Cloaking is the term used to hide vessels from visual and sensory
Since as early as the 23rd century, the Federation has struggled to
compete with invisible enemies.
The first cloaking device encountered by the Federation was in 2266,
under use of the Romulan Star Empire. Cloaking technology was shared
with the Klingons around 2268, during an alliance with the Romulans.
The Federation agreed to prohibit the use of cloaking devices on its
ships in the 2310's,
in the Treaty of Algeron. The one and only exception has been the U.S.S.
Defiant, but even then it was only to be used in the Gamma quadrant,
and in exchange for intelligence reports
on the Dominion. A cloak is an energy screen.

meetings with cloaked enemies, has devised methods to find such ships.
One is using a tachyon heterodyne detection grid, a network of tachyon
Developped by Geordi LaForge, the net is disrupted when cloaking fields
are passed through. Other methods include using subspace

gravitic sensor nets that can detect the use of the nullifier cores.
