Stealth Stealth was a form of camouflage technology or ability to render anything from planet s , space station s , starship s , and personnel to small equipment and devices invisible , or at least undetectable to sensor s . Stealth technology . Many spacefaring civilizations used varying forms of stealth technology . Perhaps the epitome of stealth was the cloaking device , which used selective bending of light and emission dampening to render a ship totally invisible and undetectable . This was used by many organizations , including the Romulan Star Empire , the Klingon Defense Force , the Hierarchy , the Sky Spirit s , the Aldean s , the Minosian s , the Ba ' Neth , the Sphere - Builder s , and the Suliban Cabal . However , the power consumption of cloaking technology were high , meaning weapons , shields , and transporter s could not always be used while a cloak was on , at least in the early stages of the technology . ( ; ; ; ; ; ; ; ) The holy grail of cloaking technology was a phasing cloak , which allowed a starship to pass through solid matter and made it impervious to conventional weapons . ( ) Other technology could be used to achieve the same effect , such as subspace force field s with adjusted synchronic distortion , interphase generator s , or other interphase devices . These systems could be used to alter the phase variance of matter and energy to disappear from the perceptual range . ( ; ) More primitive versions of stealth were known to be used by many other races , such as the stealth technologies used by the Xyrillian s , the Hirogen , and the Kazon - Nistrim called masking circuitry . ( ; ) The people of Cheron had an unusual yet advanced form of stealth technology . Their ships were perfectly detectable by sensors , but sheathed in special materials that made them completely invisible . ( ) Where as Baran ' s mercenary vessel was sheathed with energy absorbing material that made it virtually undetectable to long range sensors , while the ship itself remained visually detectable . ( ) Starfleet advanced long - range torpedo es were designed to be undetectable and untraceable after they were launched . ( ) Deflector shield s could be used to produce stealth . They could be modulated to produce an interferometric dispersion to scatter RADAR signals ( ) and hide from more advanced sensors with refractive and multi - adaptive shielding . ( ) Subspace could be used as a place of concealment . The Dominion used anti - personnel mine s that hid in subspace and appeared at random to normal space . ( ) The " Think Tank " could also be absorbed into subspace to hide from detection . ( ) Stealth technology might also include the use of holographic equipment and was not limited to space travel . In 2154 , the Romulans deployed two drone ships that used holographic technology in the form of a multispectral emitter system to disguise themselves as other vessels . ( ) The Federation used holographic technology to hide facilities called duck blind s from pre - warp civilization s ( ) and isolation suit s to hide the personnel on these assignments . ( ) Vosk , leader of the Na ' kuhl , developed a form of stealth time travel that enabled him to escape ' forces in the 29th century to an alternate 1944 Earth . ( ) There were were also several methods of stealth transporting , in which it was possible to beam though deflector shields and extremely difficult for others to determine the origin and destination of the transports . These included the inverter used by the Ansata terrorists on Rutia IV , the subspace transporter used by Bok , and the ancient Iconian gateway system . ( ) Biological stealth . Some species even possessed a biological ability for invisibility , such as the and the Jem ' Hadar who had the ability to " shroud " themselves in a camouflage that acted as a personal cloaking field . This effectively hid them and their weapons from the naked eye and in the case of the Jem ' Hadar from sensors as well . ( ) The Devidian s could shift their own phase variance ( ) and the parasitic interphasic organism s from Thanatos VII lived in a natural state of interphase . While they could attach to their victims , they themselves couldn ' t be seen or touched . ( ) Other species had a chameleon - like ability to appear invisible such as the species native to Tarchannen III who produced a mimetic radiant effect in their skin and some of the genetically enhanced Suliban who possessed a similar ability from subcutaneous pigment sacs and the bio - mimetic garment s they wore . ( ; ) Several shapeshifting species could use their abilities as a form of stealth . The Changeling s had the ability to use their morphogenic enzymes to appear as fire , fog , inanimate objects , flowers , trees , and harmless small animals to avoid detection . ( ) Members of the shapeshifting Dakala n wraith species had a similar ability to hide from their hunters by becoming an inanimate object such as a rock . Sensors would also identify them as being composed of rock when they assumed that shape . ( ) The Daledian allasomorph s had the ability to alter their molecular structure to become smaller animals to avoid detection . ( ) Members of Fantome ' s species had the natural ability to refract their life sign s , making them undetectable to sensors . ( ) A substance was added to the cellular structure of Angosian soldiers , who fought in the Tarsian War , to shield electrical impulses , making the soldiers undetectable to sensors . ( ) Similarly , members of Species 8472 generated a type of bioelectric field that rendered them impervious to sensors and made transporter locks on them difficult . ( )
