In several science fiction universes, a cloaking device is an advanced stealth system which causes an object, such as a spaceship or individual, to be invisible and extremely difficult to detect with normal sensing instrumentation. Klingons ( Klingon: tlhIngan; Pronunciation /ˈt͡ɬɪŋɑn/ are a warrior race in the fictional Star Trek universe Klingon Starships appear in televised and filmed installments of the Star Trek Fictional universe. Star Trek VI The Undiscovered Country is the sixth feature film based on the Star Trek Science fiction Television series. A fictional universe is a self-consistent fictional setting with unique background elements such as an imaginary history or geography and possibly fantasy or science Stealth technology also known as LOT (Low Observability Technology is a sub-discipline of military Electronic countermeasures which covers a range of techniques used with A spacecraft is a Vehicle or machine designed for Spaceflight.
In Star Trek, cloaking devices were first introduced and used by the Romulans in the Original Series episode "Balance of Terror", though the device was only referred to as "a practical invisibility screen. Romulans are an alien species in the Star Trek universe that are related to the Vulcans and are at war or in an uneasy truce with the United Federation of Star Trek is a Science fiction Television series created by Gene Roddenberry that aired from September 8, 1966 through The phrase " balance of terror " is usually used in reference to the nuclear Arms race between the United States and the Soviet Union " The invisibility came as a surprise to the crew of the USS Enterprise, who considered it only a theoretical possibility. The USS Enterprise (NCC-1701 is a Starship in Star Trek, which chronicles the vessel's mission "to explore strange new worlds to In a later episode, "The Enterprise Incident", the Enterprise is sent on a mission to capture one of the devices, and the device is first given its name in that episode. " The Enterprise Incident " is a third season episode of Star Trek The Original Series, first broadcast September 27, 1968 Decades later, the episode "Minefield" of Star Trek: Enterprise contradicted this by revealing that Romulans possessed a form of cloaking technology in the mid-22nd Century, suggesting that what was featured in "Balance of Terror" et al was some sort of improvement, or that, for some reason, Starfleet Intelligence (or perhaps agents in the Temporal Cold War) suppressed knowledge of the cloaking devices encountered a century earlier, after the 4th season opener which ended the temporal cold war thread, all references to cloaking devices were removed by the new show runner, this could taken as part of the restored timeline. "Minefield" is the 29th episode (production #203 of the Television series Star Trek Enterprise. Star Trek Enterprise (simply titled Enterprise prior to season three is a Science fiction Television program created by Brannon This article describes the Starfleet organization in the Star Trek universe for other uses see Starfleet (disambiguation In the Fictional universe The Temporal Cold War is a Fictional conflict waged throughout history in the Star Trek universe notably during the 22nd century AD. Enterprise also encountered several other races with cloaking technology, including briefly obtaining a cloak-capable pod belonging to the Suliban. The Enterprise (NX-01 is a fictional Starship in the Science fiction Television series Star Trek Enterprise. The Suliban are a starfaring race in the fictional Star Trek universe seen throughout the series Star Trek Enterprise. In addition, the Mirror Universe Enterprise was also fitted with a Suliban cloaking device in the two "In a Mirror, Darkly" episodes. The Mirror Universe (MU is a Fictional parallel universe in which the plots of several Star Trek television episodes take place " In a Mirror Darkly " is a two-part episode of Star Trek Enterprise. The Suliban cloaking device allowed the Mirror Enterprise NX-01 to fire weapons while cloaked.
The device was next seen in Star Trek III: The Search for Spock being used by Klingons. Star Trek III The Search for Spock ( Paramount Pictures, 1984) is the third feature Film based on the Star Trek Klingons ( Klingon: tlhIngan; Pronunciation /ˈt͡ɬɪŋɑn/ are a warrior race in the fictional Star Trek universe The original script of Star Trek III featured Romulans as the antagonists, but was rewritten to feature Klingons. Much of the plot relied on the use of a cloaking device, although prior to Star Trek III the Romulans were the only race to have developed cloaking technology. To explain how the Klingons acquired cloaking technology, fans have speculated that as part of an earlier mentioned Romulan-Klingon alliance, the cloaking device was given to the Klingons in return for warp drive. Warp drive is a form of Faster-than-light propulsion in the Fictional universe of Star Trek, capable of propelling spacecraft or objects to many multiples Critics of this theory point out that this requires the Romulans to have fought an interstellar war without faster-than-light drives. The Enterprise episode "Minefield" shows cloak-using Romulans in a system that was far away from Romulan space, which would certainly have required the use of a warp drive. Star Trek Enterprise (simply titled Enterprise prior to season three is a Science fiction Television program created by Brannon The alliance must have existed, however, as Romulans have been seen using a Klingon ship in the original series. This has led some fans to theorise it was this ship, the D-7, that was traded to the Romulans as opposed to the warp drive.
Cloaking is not perfect. In "Balance of Terror", the Enterprise was still able to detect the Romulan ship on motion sensors, and in the Star Trek: Deep Space Nine episode "The Search" we learn that running at a high warp speed may allow detection. "The Search" is the title of a two-part episode of Star Trek Deep Space Nine, the first episode of the third season The biggest weakness is that the device has such high power demand, it must be deactivated for a ship to enter combat. Thus, an alert enemy can target it normally when the ship decloaks. Another weakness on older Klingon ships is the need to drop the force field in order to use the cloak as it utililizes the same power systems as the shields. This was shown in the movie Star Trek Generations where the Enterprise was able to cloak the Klingon vessel using an ionic pulse and then target the cloaking ship whose shields had to go down in order for the cloak to engage. Star Trek Generations is a 1994 Science fiction film and the seventh feature film based on the Star Trek science fiction television A major plot element of Star Trek VI: The Undiscovered Country was the invention of a new type of cloaking device that would allow firing whilst cloaked. Star Trek VI The Undiscovered Country is the sixth feature film based on the Star Trek Science fiction Television series. However, it was learned that the prototype ship using it could be tracked by plasma (ionized gas) exhaust from the ship while moving at impulse. In Physics and Chemistry, plasma is an Ionized Gas, in which a certain proportion of Electrons are free rather than being bound In the fictional Star Trek universe the impulse drive is the method of propulsion that Starships and other Spacecraft use when they are travelling It is very strange that no such technology was shown to be possessed by the Klingons 70-80 years later.
In the Star Trek: The Next Generation episode "Redemption", the Federation discovers a way to use nets of tachyon beams to set traps for cloaking ships. Star Trek The Next Generation ( STTNG or TNG) is an Emmy and Peabody Award-winning science fiction television program created by Gene Roddenberry " Redemption " is the name of a two-part Star Trek The Next Generation Episode. A tachyon (from the Greek, takhyónion, from, takhýs, ie swift fast is any hypothetical particle that travels at Faster-than-light
In the Star Trek: Voyager episode "Prophecy", Voyager encounters a Kirk-era Klingon vessel wandering the Delta Quadrant. " Prophecy " is an episode of the TV series Star Trek Voyager, the fourteenth episode of the seventh season In the television series Star Trek and its spin-offs Galactic quadrant refers to an area of the Milky Way Galaxy (although it's apparently no longer called A brief exchange between Janeway and Tuvok indicates that a simple method of detecting cloaked ships of that era is common knowledge in Voyager's time. Kathryn Janeway, played by Kate Mulgrew, is a main character of the Television series Star Trek Voyager. Tuvok, a Vulcan played by Tim Russ, is a character on the television series Star Trek Voyager where he serves as the ship's chief of security "As detection methods advance, so too do cloaking devices".
Many have wondered why the Federation did not begin using cloaking devices after Kirk captured one. The reason is that Gene Roddenberry depicted a Starfleet that morally rejected such a "sneaky" technology despite the obvious strategic advantage being ceded to the Romulans. Eugene Wesley "Gene" Roddenberry (August 19 1921 &ndash October 24 1991 was an American Screenwriter and producer. An in-universe explanation is that the Federation signed a peace agreement in 2311, the Treaty of Algeron, in which they promised not to develop cloaking technology ("The Pegasus"). The following is a list of treaties in the Star Trek Fictional universe. " The Pegasus " is the 164th episode of the Science fiction Television series Star Trek The Next Generation and the 12th Satisfied that the Federation would not develop threatening technology, the Romulans then turned their attentions inward, and for the most part withdrew from galactic affairs for over fifty years ("The Neutral Zone"). " The Neutral Zone " is the finale of the first season of Star Trek The Next Generation. However, the "The Pegasus" did depict a failed covert Federation programme to develop a phased cloaking device.
In Deep Space Nine, the Romulan Empire allowed Starfleet to place a cloaking device on board the USS Defiant. The USS Defiant (NX-74205 is a fictional Starship in the television series Star Trek Deep Space Nine (DS9 and the Feature film Originally, the Federation was only allowed to use the device in Gamma Quadrant space, in exchange for any Federation intelligence gathered from the Defiant. However, that restriction soon was regularly ignored by Captain Sisko, who used the device to hide from Klingon vessels during the brief breakdown in relations between those two powers. It was also discovered that the Dominion could detect a cloaked ship by scanning the area with an anti-proton beam. In Particle physics and Quantum chemistry, antimatter is the extension of the concept of the Antiparticle to Matter, where antimatter is composed It's not clear if the Federation is still prohibited from using cloaking technology, or if the two powers have since signed a new agreement regarding such technology.
Jem'Hadar warriors are born with the ability to "shroud" themselves naturally making them invisible to the naked Human eye and most sensors, though this cannot be achieved if the individual is suffering from Ketracel White withdrawal due to the intense concentration required. In the fictional Star Trek universe the Jem'Hadar are the Shock troops of the powerful Dominion located in the Gamma Quadrant. In the fictional Star Trek universe the Jem'Hadar are the Shock troops of the powerful Dominion located in the Gamma Quadrant. This concentration also forces a Jem'Hadar to stop shrouding before performing any action requiring focus, such as attacking. The Tosk, who are possibly related to the Jem'Hadar, possess a similar ability. "Captive Pursuit" is the sixth episode of the first season of Star Trek Deep Space Nine.
In Star Trek Nemesis, the Remans developed a new cloaking device which was impenetrable to Federation scans. Star Trek Nemesis ( 2002) is the tenth feature Film based on the Star Trek television series In the fictional Star Trek universe Remans are natives of the planet Remus, resembling bats. This was employed on Shinzon's ship the Scimitar. This article lists characters in the various canonical incarnations of Star Trek. Star Trek Nemesis ( 2002) is the tenth feature Film based on the Star Trek television series The Reman cloaking device employed Thaloran radiation as the source of power. The radiation also had the affect of transforming biomatter to stone. Like the Klingon ship in Star Trek VI, the Scimitar had the ability to fire while cloaked, and also demonstrated the ability to raise its shields. This reflects a fundamental change in cloaking technology, as the biggest drawback of no shields has been overcome.
Cloaking devices play a much less significant role in the Star Wars universe. The first Star Wars reference to cloaking devices is heard in The Empire Strikes Back when Captain Needa states that no ship as small as the Millennium Falcon can be equipped with a cloaking device—however, the Expanded Universe has appeared to contradict this in places, mentioning that Emperor Palpatine's shuttle had a cloaking device, as did the personal spaceship of his early apprentice, Darth Maul. Star Wars Episode V The Empire Strikes Back is a 1980 Space opera Film directed by Irvin Kershner. This article is about minor Villains in the Fictional Star Wars universe. The Millennium Falcon is a fictional spacecraft in the Star Wars universe commanded by smuggler Han Solo ( Harrison Ford) and his The Star Wars Expanded Universe encompasses all of the officially licensed fictional background of the Star Wars universe outside of the six feature films Palpatine is a Fictional character in George Lucas 's Science fiction saga Star Wars. Darth Maul is a Fictional character in the Star Wars universe and a villain in Star Wars Episode I The Phantom Menace. Various retcons have been proposed, most notably by Dan Wallace who suggests that this discrepancy could be retconned as Needa referring to power requirements of early hibridium cloaking prototypes, or possibly the power requirements of the old, failing, stygium cloaking devices. 
The Expanded Universe Star Wars books and games have included and elaborated upon cloaking devices, and have presented a solution to the earlier problem as to how big a ship has to be equipped with such a device: the original cloaking devices were small objects created from very rare naturally occurring stygium crystals. The following is a list of substances including food and drugs found in the fictional series Star Wars. However, in later years (such as during the Empire) these crystals seem to have been depleted, with the surviving devices being extremely expensive, only ships as important as Palpatine's shuttle would be equipped with them. By the time of The Empire Strikes Back, the only cloaking devices known to exist (without the aid of stygian crystals) were much larger, and required vast amounts of power, as well as the design being an Imperial military secret. It is one of these far less practical devices that Captain Needa was referring to.
In the Star Wars: Battlefront II game, a Bothan Spy has the ability to activate a cloaking device which also hides the weapon. Star War Battlefront II is a First-person shooter / Third-person shooter Video game developed by Pandemic Studios, and published by
The plot of the Rebel Assault II video game concentrates on the danger presented by a type of TIE fighter that can cloak, according to the game the first ship of the size with such a capability. Star Wars Rebel Assault II The Hidden Empire is the sequel of the LucasArts action game Star Wars Rebel Assault, set in the Star Wars A video game is a Game that involves interaction with a User interface to generate visual feedback on a video device. TIE fighters are fictional Starfighters in the Star Wars universe This "TIE Phantom", a modified V-38, was the brainchild of the genius Grand Admiral Martio Batch. The new fighter had undergone some combat experience and entered production before the factory and all existing models were destroyed. The cloaking device of the TIE Phantom seems to be fueled by oridium ore and produces a "cloak field" that renders the fighter effectively invisible to both electronic sensors and human sight. The fighter becomes visible a short time before firing, suggesting the cloak field renders the ship double-blind. As the fighter cloaks or uncloaks, various parts of it fade in and out of view and the ship shimmers a bluish color. The TIE Phantom's cloaking device is considered by some to be more of an active stealth system with electronic systems to break up incoming sensor beams and a refractive surface covering to make it harder to spot visually.
In the PC game TIE Fighter, the Vorksnix Project manages to develop an experimental cloaking device that is small enough to be used on a Corvette. TIE Fighter, a computer space combat game, is the sequel to Star Wars X-Wing, and the first game of the series that puts the However, it had a significant flaw in that it was very unstable when used in conjunction with a hyperdrive. Attempting to operate both at the same time would cause the ship to explode.
The Star Wars universe's cloaking devices were a major element of The Thrawn trilogy: it was explained that cloaking devices in the Star Wars galaxy are limited by fundamental laws of physics (in order to observe, one must be observable as well) and were never put into widespread use because of this limitation. The Thrawn trilogy, also known as the Heir to the Empire trilogy, is a series of best-selling Novels written by Timothy Zahn. The cloaking device renders a ship effectively "double-blind"; a ship using a cloaking device can sense nothing about its surroundings. Although a cloaked ship could fire while cloaked, it would be firing blindly and the probability of hitting its target would be minimal to the point of impracticality, even with the addition of a fire control predictor computer to the system. Worse, basic navigation was impossible, and a cloaked ship might end up fatally ramming an enemy ship or a friendly ship. Communication with a cloaked ship is also impossible.
Despite the Empire's attempt to produce and use a cloakable fighter, cloaking devices were never widespread in the Star Wars universe. Using the insane Dark Jedi Master Joruus C'baoth, Imperial Grand Admiral Thrawn successfully implemented a plan whereby C'baoth would use the Force to communicate with the firing crews on cloaked Dreadnaughts, allowing him to A) fool the New Republic into thinking he had developed or obtained a weapon that could fire through planetary shields, which he had not, and B) in the ingenious conquest of the planet Ukio with its defenses intact. Master C'baoth is a fictional character in the Star Wars Expanded Universe. Grand Admiral Thrawn (full name Mitth'raw'nuruodo) is a Fictional character and major antagonist from the Star Wars galaxy. The Force is one of the main concepts in the fictional Star Wars universe, created by George Lucas. See also List of Star Wars starfighters The following is a list of Fictional Starships cruisers Battleships and other Spacecraft in the Basic Premise of the New Republic "The New Republic is a mutual self-protection pact among over four hundred sentient species and an economic partnership between Ukio was an important foodstuff-producing plant vital to Thrawn's plans to rapidly expand his forces with clones, and when his fleet advanced Ukio activated their planetary shields, rendering them impervious to orbital bombardment. However, Thrawn had already positioned cloaked Dreadnaughts beneath the planetary shield, and using C'baoth's communication with the cloaked ships, he executed an incredibly well timed maneuver: his Star Destroyers would fire at ground targets that were directly underneath the cloaked Dreadnaughts; the Star Destroyer fire would be deflected by the shield, but C'baoth would order the cloaked ships to fire a split second later: to the observers on the ground, it appeared that the Star Destroyers were firing through the planetary shield, and Thrawn fooled them into thinking this was some sort of new superweapon which they had no defense against. Star Destroyers are iconic vessels of the fictional Star Wars universe The government of Ukio then contacted Thrawn and surrendered, with their planetary defenses fully intact for Thrawn to take control of. However, the ruse was eventually revealed, and with the death of C'baoth, cloaking devices were again rendered impractical for widespread deployment.
Grand Admiral Thrawn also devised a use in which a cloaking device was used to conceal several squadrons of TIE fighters and mole miners inside a freighter's cargo bay, which was then piloted into a heavily-used shipyard (Sluis Van). Grand Admiral Thrawn (full name Mitth'raw'nuruodo) is a Fictional character and major antagonist from the Star Wars galaxy. TIE fighters are fictional Starfighters in the Star Wars universe Ragoon 6 A dangerous yet lush world Ragoon 6 was the location of a Jedi training site The freighter's cargo was cloaked instead of static damped, to reduce suspicion as to the surprise in the cargo bay. The freighter was scuttled explosively, and the fighters released in a surge to the complete surprise of the yard's defenders. This was timed to coincide with an attack by several Star Destroyers. Star Destroyers are iconic vessels of the fictional Star Wars universe
Thrawn also developed one additional tactic involving the use of cloaking devices—as a siege weapon. This tactic was only used once, involving, as it did, an enormous amount of resources, but it was highly successful. Essentially, Thrawn attacked the then-New Republic controlled Couruscant with a full fleet. As the battle progressed to the point that Thrawn wished, Thrawn's flagship Chimaera (as well as other Star Destroyers present at the battle) began to launch 22 cloaked asteroids, knowing, and intending, that the energy of the launches would be detectable by surface-based sensors. However, the asteroids were launched cloaked, and to further the confusion of the defenders, the tractor beam emitters had shunts attached to them, allowing them to draw power—and thus be detectable on the sensor boards—without them actually doing anything. So, when the New Republic military detected a grand total of 287 tractor launches from Chimaera and other Star Destroyers present, they were faced with the possibility of having to find up to that number of cloaked asteroids, in unstable orbits around Coruscant, that would eventually crash down on the planet. As a 40-meter asteroid would do an incredible amount of damage on a planet with Coruscant's population density, they were unable to lower the planetary shields. Besides requiring massive amounts of energy, this also prevented any ships from landing, shutting the planet off from food supplies and other important imports.
In the Dark Nest trilogy showed that the Chiss, a species that Thrawn belonged to, utilized a Star Destroyer design that featured a working cloaking device. A Chiss is also a Fictional creature from L Frank Baum 's Oz books.

Sith Assassins from Star Wars: Knights of the Old Republic II The Sith Lords also use Stealth Field Generator devices to attack enemies, but their only difference from the player is, their weapons can attack while the generator is active and only switched off once the assassin is injured. Star Wars Knights of the Old Republic II The Sith Lords ( KotOR II) is a role playing Video game released for the Xbox In Knights of the Old Republic II, G0-T0's Yacht also poses a clocking device to protect it from republic and other ships due to its pirating of trading ships entering the Nar-Shadda system, the Jedi Exile deactivated this from four controls inside the yacht and as soon as they escape the ship, it is almost instantly destroyed.
In the TV series Stargate SG-1, Goa'uld Tel'tak cargo ships have an imperfect cloaking device which makes them invisible but still allows for detection; this has been modified (to the surprise of SG-1 and the dismay of the Tok'ra) by the System Lord Apophis to cloak entire Ha'tak motherships. In the Science fiction Television series Stargate SG-1, the Goa'uld (pronounced go-ah-OOLD or, commonly mispronounced or shortened The Tok'ra are a fictional alien race on the Science fiction Television series Stargate SG-1. This is a list of the Goa'uld characters that have appeared so far in Stargate, Stargate SG-1, and Stargate Atlantis. Anubis, a partially Ascended goa'uld (and therefore in possession of some of the knowledge of the race that built the Stargates, the Ancients, who also Ascended), regularly used Al'kesh (mid-range bombers) that were capable of cloaking. (It was unclear whether all Al'kesh ships in all the goa'uld fleets could cloak, or just those used by Anubis and Apophis after his takeover of Sokar's fleet; since those are the only Al'kesh ever seen to cloak, however, the latter possibility seems more likely. )
In "The Shroud", when Daniel Jackson has become an Ori Prior, he upgrades The Odyssey with a cloaking device, powered by a ZPM.

In the Xbox 360 video game Mass Effect, the SSV Normandy is equipped with a stealth system that relies more on the masking of thermal emissions rather than optical invisibility. The Xbox 360 is the second Video game console produced by Microsoft, and was developed in cooperation with IBM, ATI, and SiS. Mass Effect is an Action role-playing game developed by BioWare for Xbox 360 and Microsoft Windows. In the game, ship sensors detect emissions such as heat and radiation from other ships' engines. The Normandy's stealth system shunts these emissions into sections of the ship's hull, where the energy is stored and kept from leaking out. As a result, the ship becomes completely invisible to passive sensors (visual detection is still possible, but unlikely against the darkness of space). The Normandy can only maintain "stealth mode" for a few hours before having to vent the energy into space and thus reveal its position, otherwise the contained energy will boil the inside of the ship.
The title character of the Predator films uses an imperfect cloaking device; although the Predator is virtually invisible while stationary, movement causes a characteristic "shimmer" effect, and it's wrist blades extend inside the field. Predator is a 1987 science fiction, action and Horror film directed by John McTiernan, starring Arnold Schwarzenegger Unlike the other mentioned types of cloaking field, the device equipped to the Predator Suit allows for continuous cloaking, even during hand-to-hand combat. Contact with water, even as shallow as a puddle, causes the device to temporarily short-circuit, rendering the Predator visible.
In the 1996 Doctor Who television movie based upon the long-running British series, Doctor Who, the Doctor's TARDIS was said to possess a "cloaking device" that got stuck, leaving it in the form of a British police box.

"Boom Town" also contains the first mention of the perception filter. " Boom Town " is an episode in the British Science fiction television series Doctor Who, which was first broadcast on This is a list of items from the BBC Television series Doctor Who. A perception filter is a field generated by a TARDIS that convinces people to ignore it, which in the case of the Doctor's TARDIS makes the normally anachronistic police box seem perfectly ordinary wherever it lands, no matter how out of place it may be. In "Boom Town," the TARDIS also imparts a perception filter to a stone slab near a fountain in Cardiff, which Torchwood Three has attached to an elevator, as seen and first named in the Doctor Who spin-off Torchwood. This article is about the organisation within Doctor Who; for the spinoff programme see Torchwood. Doctor Who is a British science fiction television programme produced by the BBC. Torchwood is a British science fiction Drama Television programme, created by Russell T Davies and starring John Barrowman In "The Sound of Drums" it is suggested that the field extends to objects associated with the TARDIS, such as the keys used to open it.

Perception filters can also be added to other objects, such as the fob watches used by the Doctor and the Master. This is a list of items from the BBC Television series Doctor Who. The Master is a recurring character in the British Science fiction television series Doctor Who. The field does not work if the object it surrounds draws too much attention to itself, or if someone is specifically searching for the object in question.
In the anime series Ghost in the Shell: Stand Alone Complex (continuing in its second season under the name 2nd GIG), Section 9 employs "optical camouflage" suits which allow the wearer to render himself completely invisible. is the second season of the Japanese Anime series Ghost in the Shell Stand Alone Complex, based on Masamune Shirow 's ''Ghost in the Shell'' Public Security Section 9 ( Japanese: 公安9課 Kōan Kyūka) also referred to as Public Safety Section 9 in some translations is a fictional intelligence The older models did not hide shadows or body heat, but as Solid State Society suggests, later models were designed that cloaked even these methods of detection. is the 2006 anime film based on the Ghost in the Shell Stand Alone Complex series which is based on Masamune Shirow 's Manga Often characters using this optical camouflage will disengage it after using it for a short period of time, but they have been known to use it while firing and attacking. Presumably the camouflage eats away at a power source, so it's best used for short time sets. Sometimes the suits can be seen slightly, and other times not at all; in episode 21 "Eraser", there is a scene where the Major can plainly see two enemies using optical camouflage, but it is unclear whether Section 9 simply has the best quality optical camouflage or not. In the series, the camouflage seems to become disrupted when it comes into contact with water, while in the original movie it does not, although as the movie is set after the series, this could be due to technological advances.
The Deathscythe Hell from the 1995 anime Mobile Suit Gundam Wing employs an active camouflage system that makes it invisible to visual and sensor detection.

In the Metal Gear series, portable cloaking technology is a reality. is a critically acclaimed series of Stealth games created by Hideo Kojima and developed and published by Konami. Within this series, the "stealth camouflage", as it is referred to, comes in the form of a small device about the size of a bulky CD player and in the MGS remake at the end, Otacons type resembles a bulky scientific calculator. When activated, the user becomes mostly invisible, save for a slight "ripple-effect" when in motion. The device is also featured anachronistically in Metal Gear Solid 3, where the game is set in the 1960's. An anachronism (from the Greek "ana" " ανά " "against anti-" and "chronos" " χρόνος " (commonly abbreviated to MGS3) is a stealth action Video game directed by Hideo Kojima. The device does have a drawback; it is depicted to consume stamina so great that the wearer needs to replenish his/her stamina every now and then, whereas its modern counterparts do not feature such limitations. Players can acquire this camouflage for themselves as a reward for accomplishing special task(s) prior to completion of the game. (ex. collecting all of a certain item, remaining undetected for the entirety of the game, or performance on special sections of the game. )
In the RTS game Total Annihilation (TA) a small number of units have the ability to cloak, becoming invisible. A real-time strategy ( RTS) Video game is a strategic game that is distinctly not turn-based. Total Annihilation (abbr TA) is a critically-acclaimed Real-time strategy game created by Cavedog Entertainment and released The starting unit of both ARM and CORE, the Commander unit, has the ability to cloak. Other units which can cloak include the ARM 'Shooter' sniper Kbot and the ARM 'Infiltrator' and CORE 'Parasite' spy Kbots. The ARM 'Podger' and CORE 'Spoiler' vehicles can lay land mines which are automatically cloaked (although this feature can be deactivated to save energy if necessary). A land mine is an Explosive device designed to be placed on or in the ground to explode when triggered by an operator or the Proximity of a vehicle person Both sides can build cloakable Fusion power plants. Fusion power is power generated by Nuclear fusion reactions In this kind of reaction two light atomic nuclei fuse Cloaked units in TA will uncloak if they fire a weapon, use their nanolathe or if an enemy unit approaches within a specific radius, they will also uncloak if the player runs low on/out of energy. In the RTS computer games Total Annihilation and Supreme Commander, nanolathes are the systems used by construction units and structures to more Also, although invisible, they are still detectable by radar. All cloaking devices (with the obvious exceptions of both mines and reactors) consume exponentially larger amounts of energy while moving, and fail completely upon the activation of a weapon or tool. With the exception of the Commanders, all other units with cloaking ability come with Total Annihilation: The Core Contingency expansion pack. The Core Contingency is a 1998 expansion to the popular 1997 Real-time strategy computer game Total Annihilation Also present in TA are related concepts such as radar invisibility and radar and sonar jamming. Radar is a system that uses electromagnetic waves to identify the range altitude direction or speed of both moving and fixed objects such as Aircraft, ships Sonar (which started as an Acronym for sound navigation and ranging) is a technique that uses Sound propagation (usually underwater to navigate
In the RTS game Homeworld, one can build cloak generators to hide a fleet, and playing as the Kushan gives you access to the cloaked fighter. Homeworld is a Real-time strategy (RTS Computer game released in 1999 developed by Relic Entertainment and published by Sierra However, the technologies are far down the tech tree, and cloaked ships can easily be detected by proximity sensors or sensor arrays. Furthermore, the cloaked fighter has weak attack power, long construction time, and must decloak when attacking. In the sequel, Homeworld 2, both races are able to build the cloak subsystem which performs a similar function to cloak generators. Homeworld 2 is a Real-time strategy computer game sequel to Homeworld developed by Relic Entertainment.
In the RTS game StarCraft, the Terrans possess cloaking devices, which allow Wraiths to turn invisible, as well as Personal Cloaking for Ghosts. StarCraft is a Military science fiction Real-time strategy Video game developed by Blizzard Entertainment. The Dark Templar also learned how to bend light to make themselves virtually invisible. Blizzard Entertainment's 1998 bestselling Real-time strategy game series StarCraft revolves around interstellar affairs in a distant sector of the galaxy A gravitational lens is formed when the light from a very distant bright source (such as a Quasar) is "bent" around a massive object (such as a cluster of The Protoss Arbiter has the ability to automatically cloak all nearby friendly units, excluding the Arbiter itself and any other Arbiters. Blizzard Entertainment's 1998 bestselling Real-time strategy game series StarCraft revolves around interstellar affairs in a distant sector of the galaxy The Protoss Observer remains perpetually cloaked, but has no attack. StarCraft is a Military science fiction Real-time strategy Video game developed by Blizzard Entertainment. Incidentally, the Terran devices use Energy (both devices instantly draw 25 Energy units when activated, and then consume 1 Energy unit per second until deactivated) to stay active (and the Ghost uses the same Energy pool for cloaking and the Lockdown ability), while Protoss cloaking abilities are "always on" and do not consume Energy. Magic points ( MP; also called mana) are units of magical power that are used in many role-playing, computer role-playing and similar games The Zerg do not have cloaking technology, but most Zerg land units can "burrow" to hide from enemies; like cloaked units, burrowed units are invisible to most units, but unlike cloaked units, they are also immobile and cannot attack (except the Brood War expansion Lurker unit, which attack only while burrowed). StarCraft Brood War is an Expansion pack for the award winning military science fiction, real-time strategy Video game In Starcraft cloaked units may attack without becoming uncloaked, but certain buildings and units with the Detector attribute can reveal their positions, allowing enemy units to target them. These include the Terran Science Vessel, Terran Missile Turret, Zerg Overlord, Zerg Spore Colony, Protoss Observer, and Protoss Photon Cannon. In addition, Terran Vulture Spider Mines (which themselves remain burrowed and invisible except to Detector units - at least until triggered), while not able to directly reveal cloaked units, can themselves be triggered by (and attack) cloaked non-hover ground units. The Terran ComSat Station add-on to their Command Center building, while lacking the detector attribute for it's own sight radius, can use a Scanner Sweep to temporarily reveal any cloaked (or burrowed, or otherwise hidden) units in a target area anywhere on the map. Certain effects, such as Irradiate or Ensnare, that are accompanied by visual effects, have the side-effect of making affected units visible, to all players, even while cloaked (but not while burrowed). Attacking while cloaked will reveal the presence of a unit to the enemy (and to astute human players, the location of the unit, since muzzle flashes and in-flight projectiles of cloaked units are still visible), most likely prompting the use of one of the above counter-measures (detector unit, scanner sweep, area-effect ability) to reveal the cloaked unit. Cloaked or burrowed ground units (including Spider Mines), detected or not, will prevent buildings from being constructed, and airborne Terran buildings (or Infested Command Centers) from landing, on top of them - the positions they occupy will be shaded red (marked as non-buildable) in the building placement template. Cloaked and burrowed units, even when not detected, are not invincible, and can still be harmed by spider mines (if applicable to the unit type in question), area-effect attacks (i. e. psionic storms and nukes) or units with splash-damage weapons (like Reavers or siege-mode Siege Tanks) attacking nearby targets.
In the computer and video game Deus Ex, one of the types of augmentation canister the player finds allows them to choose between either cloaking, or radar transparency, making them invisible to either humans and animals, or robots and cameras, respectively. Deus Ex (abbreviated DX and pronounced as ˌdeɪəsˈɛks day-uss ex) is a Cyberpunk -themed Action role-playing game developed These augmentations cannot be used for very long because of their extremely high power requirements, especially if used in conjunction with other augmentations.

The Command & Conquer series of RTS games by Westwood Studios has multiple instances of cloaking. Command & Conquer (often abbreviated as C&C or CNC) is a Video game franchise, mostly of the Westwood Studios ( 1985 - 2003) was a computer and Video game developer, founded in 1985 as Westwood Associates by Brett Sperry In the original Command & Conquer game, Nod had the capability to build stealth tanks armed with missiles, the tanks were completely invisible but uncloaked if they came to close to an enemy unit or fired their weapons. In Red Alert: Counterstrike, a tank that fires missiles can cloak, but uncloaks if it gets too close to an enemy. Command & Conquer Red Alert is a Real-time strategy Computer game of the Command & Conquer franchise, produced by Westwood Studios In Command & Conquer: Red Alert 2, Albert Einstein creates a "mirage tank" which can changes its outward appearance to look like vegetation. Albert Einstein ( German: ˈalbɐt ˈaɪ̯nʃtaɪ̯n; English: ˈælbɝt ˈaɪnstaɪn (14 March 1879 – 18 April 1955 was a German -born theoretical In Command & Conquer: Tiberian Sun, the Brotherhood of Nod can create Stealth Tanks, which are invisible except to special sensors until it uncloaks to fire missiles. The Command & Conquer Tiberian series is a sub-series of Real-time strategy Video games belonging to the extensive Command & Conquer franchise Also the Brotherhood has the ability to create large "Stealth Generators" that can cloak entire bases, making the area of a base seem like empty ground. Similar technologies are employed by Nod in Command & Conquer 3: Tiberium Wars, with the stealth tank being almost identical as in Tiberian Sun. The stealth generator has been replaced with the Disruption Tower, which while it creates a large cloaking field, is not cloaked itself, and so is vulnerable to attack (similar to the arbiter in StarCraft. StarCraft is a Military science fiction Real-time strategy Video game developed by Blizzard Entertainment. ) Nod also have new cloakable units, such as the vertigo bomber, and the tiberium harvester. The avatar mech is also capable of cloaking, by ripping the cloaking device from a stealth tank. this destroys the stealth tank in the process.
In Douglas Adams' Life, the Universe and Everything, the third novel in the Hitchhiker's Guide to the Galaxy series, Slartibartfast's ship, the Bistromath, utilizes a Somebody Else's Problem field. Life the Universe and Everything ( 1982, ISBN 0-345-39182-9 is the third book in the five-volume Hitchhiker's Guide to the Galaxy Slartibartfast is a character in The Hitchhiker's Guide to the Galaxy, a Comedy / Science fiction series created by Douglas Adams The SEP field relies on the mind's propensity to ignore anything which is it not expecting to see or cannot explain. This technology was developed because "the technology required to actually make something invisible is so complex that most of the time it's simpler to take the thing away and hide it. " The technology is much simpler than a cloaking device because it relies on human nature, and in addition can be run for centuries on a single 9V battery. The main disadvantage to the SEP field is that the cloaked object needs to be unexpected, thus the Bistromath is designed to look like an Italian bistro.
In the Nintendo game Metroid Prime, a select group of Space Pirates had access to cloaking technology; these are Shadow Pirates. is a Multinational corporation headquartered in Kyoto Japan founded on Metroid Prime is a Video game developed by Retro Studios and published by Nintendo for the Nintendo GameCube, released in North America is a series of Science fiction adventure Video games conceived by designer Gunpei Yokoi and produced by Nintendo. The cloaking technology used up most of the user's energy, which forces them to rely solely on melee weapons in battle. Also because of a design flaw, the cloaking devices gave off high heat ratings, making it possible for players to track down a Shadow Pirate with the Thermal Visor. A few other enemies in the Metroid Prime series featured a cloaking-like device, but could only be seen though different methods.

An operational, non-fictional cloaking device might be an extension of the basic technologies used by stealth aircraft, such as radar-absorbing dark paint, optical camouflage, cooling the outer surface to minimize electromagnetic emissions (usually infrared), or other techniques to minimize other EM emissions, and to minimize particle emissions from the object. Non-fiction is an account or representation of a subject which is presented as Fact. Infrared ( IR) radiation is Electromagnetic radiation whose Wavelength is longer than that of Visible light, but shorter than that of The use of certain devices to jam and confuse remote sensing devices would greatly aid in this process, but are more properly referred to as "active camouflage. Active camouflage or adaptive camouflage, is a group of Camouflage technologies which allow an object to blend into its surroundings by use of panels or coatings capable " Alternatively, metamaterials provide the theoretical possibility of making electromagnetic radiation appear to pass freely through the 'cloaked' object.
The Philadelphia Experiment was a secret experiment conducted by the U.S. Navy at the Philadelphia Naval Yards at Philadelphia, Pennsylvania, on or before October 28, 1943, which went horribly awry. The Philadelphia Experiment was an alleged naval military experiment at the Philadelphia Naval Shipyard in Philadelphia Pennsylvania, sometime around October Philadelphia (ˌfɪləˈdɛlfiə Events 306 - Maxentius is proclaimed Roman Emperor. 312 - Battle of Milvian Bridge: Constantine Year 1943 ( MCMXLIII) was a Common year starting on Friday (the link will display full 1943 calendar of the Gregorian calendar. The experiment was allegedly to cast a veil of radar and possibly optical invisibility or transparency around a ship. Though most mainstream experts argue the incident is an urban legend, a number of people argue that the Philadelphia Experiment could be genuine. An urban legend or urban myth is a form of modern Folklore consisting of stories thought to be factual by those circulating them Whether true or not, the Philadelphia Experiment has had a major ripple effect on conspiracy theory, and elements of the Philadelphia Experiment feature in many other conspiracy tales and provided the basis for various movies and miniseries. The ripple effect is an education-related term associated with the studies of Jacob Kounin. A conspiracy theory attributes the ultimate cause of an event or chain of events (usually Political, Social or Historical events or the concealment The Philadelphia Experiment is a 1984 Science fiction film.

Optical metamaterials have featured in several recent proposals for invisibility schemes. A metamaterial (or meta material) is a material which gains its properties from its structure rather than directly from its composition "Metamaterials" refers to materials that owe their refractive properties to the way they are structured, rather than the substances that compose them. (Opals are a well known example of a naturally occurring metamaterial. OPAL ( Open Pool Australian Lightwater reactor) is a 20 megawatt pool-type nuclear research reactor that was officially opened in April 2007 ) It has been demonstrated that such materials can take on optical properties unattainable by natural substances. Most famously, a negative refractive index is possible. A metamaterial (or meta material) is a material which gains its properties from its structure rather than directly from its composition
On February 14, 2005, Andrea Alů and Nader Engheta at the University of Pennsylvania announced in a research paper that plasmons could be used to cancel out visible light or radiation coming from an object. Events 842 - Charles the Bald and Louis the German swear the Oaths of Strasbourg in the French and German Year 2005 ( MMV) was a Common year starting on Saturday (link displays full calendar of the Gregorian calendar. The University of Pennsylvania (also known as Penn) is a private University located in Philadelphia, Pennsylvania, USA. In Physics, a plasmon is a quantum of a plasma oscillation The plasmon is the Quasiparticle resulting from the Quantization of Plasma oscillations This 'plasmonic cover' would work by suppressing light scattering by resonating with illuminated light, which could render objects "nearly invisible to an observer. " The plasmonic screen would have to be tuned to the object being hidden, and would only suppress a specific wavelength: An object made invisible in red light would still be visible in multiwavelength daylight.
A concept for a cloaking device was put forward by two mathematicians in one of the UKs Royal Society journals . The United Kingdom of Great Britain and Northern Ireland, commonly known as the United Kingdom, the UK or Britain,is a Sovereign state located The Royal Society of London for the Improvement of Natural Knowledge, known simply as The Royal Society, is a Learned society for science that was founded in 1660 Shortly afterwards, blueprints for building a cloaking device were put forward in the journal Science by researchers in the US and UK . Science is the Academic journal of the American Association for the Advancement of Science and is considered one of the world's most prestigious Scientific However, "Scientists not involved in the work said the plans appear feasible but that they would require more-advanced substances than currently exist" .
While no one has yet been able to make a cloaking device for light, in October 2006, a US-British team of scientists created a metamaterial which made an object invisible to microwave radiation . Since light is just another form of electromagnetic radiation, this is the first step to a cloaking device for light, though more advanced nano-engineering techniques will be needed due to visible light's short wavelengths.
On April 2, 2007, 2 Purdue University engineers announced a theoretical design for an optical cloaking device based on the 2006 British concept. Events 68 - Galba, Governor of Hispania, names himself legatus senatus populique Romani, breaking the line of Year 2007 ( MMVII) was a Common year starting on Monday of the Gregorian calendar in the 21st century. The design deploys an array of tiny needles projecting from a central spoke that would render an object within the cloak invisible in a wavelength of 632. 8 nanometers. 
On October 19th, 2006 the AP reported that a team of British and American scientists had demonstrated a prototype metamaterial based device that rendered a copper cylinder invisible to microwaves. Events 202 BCE - The Battle of Zama results in the defeat of Carthage and Hannibal. Copper (ˈkɒpɚ is a Chemical element with the symbol Cu (cuprum and Atomic number 29 Microwaves are electromagnetic waves with Wavelengths ranging from 1 mm to 1 m or frequencies between 0 In the prototype, microwaves passing through the cloaked object were significantly dimmed but the researchers believe this behavior can be improved. . Engineers David Schurig and David Smith of Duke University successfully, although not completely, hid or "cloaked" the central copper ring by surrounding it with concentric rings of metamaterial standing one centimetre tall and spanning 12 centimeters. Duke University is a private Research University located in Durham, North Carolina, United States. A centimetre ( American spelling: centimeter, symbol cm) is a unit of Length in the Metric system, equal to one hundredth The rings were sandwiched between two plates so that microwaves could only travel through the cloak in the plane of the rings, as described in the paper published online October 19, 2006 by Science. Events 202 BCE - The Battle of Zama results in the defeat of Carthage and Hannibal. Year 2006 ( MMVI) was a Common year starting on Sunday of the Gregorian calendar.
