Cloaking device

A cloaking device was a device that had the ability to render an object invisible to the naked eye as well as from most sensors.



The Federation and cloaking technology
Following the Treaty of Algeron in 2311, the Federation agreed not to develop cloaking technology. 

In the mid 2360s, the Captain Menchez of the IKS loaned his ship's cloaking device to Captain Daniel of the USS after Daniel had saved Menchez's reputation and life in the Klingon Empire. When the Phoenix was nearly destroyed in the Tiloniam system, in 2374, it was found that Menchez's cloaking device was salvageable. The device was later re-installed into the X-Project designed starship, USS. (: "The Tiloniam System", "Betrayal and Honour", "The Tilonian System", "These Aren't the Voyages...")



In 2383, the Phoenix-X lost its Klingon cloaking device when the ship became under attack. Following the loss, Section 31 ordered the Phoenix-X to the Mutara sector where an Interphasic cloaking device would be installed onto the ship. (: "These Aren't the Voyages...")

The interphase cloak
The Treaty of Algeron did not stop Starfleet Intelligence from secretly and illegally developing the interphase cloaking device, a device which not only rendered a starship invisible, but also allowed it to pass through solid matter unimpeded. The device was lost in 2358 when the testbed vessel, the USS Pegasus was presumed destroyed by a warp core breach in a mutiny by members of the crew concerned about the legality of the test. In 2370, the Pegasus was found not to have been destroyed and the existence of the illegal device was made public to the Romulans. The device was soon handed over to the Romulan government, but was destroyed during transport by Mackenzie Calhoun, working for Intelligence. A similar device was developed again, by Section 31, 13 years later and installed onto the Phoenix-X. (Star Trek: New Frontier: "Loose Ends", : "These Aren't the Voyages...")

The Srivani normally used phased cloaking technology to beam onto alien vessels and run scientific tests on the crew. The Srivani's medical devices were also phased. In 2383, the Phoenix-X encountered the Srivani, who ran tests on the crew until the scientists were attacked by genetically altered interphasic organisms. (: "Fantastic Method")
