2654: The Kilrathi introduce the first full cloaking device -- although currently capable of being mounted only on large, unmanned missiles, the new weapon confirms Confederation beliefs that the Kilrathi have made significant advances in the area of cloaking technology.
2655: The first Shroud-type device is tested, on a modified Sartha light fighter -- called a "Strakha". The device hides the enemy ship only from enemy radar -- and is judged a failure after one of two prototypes is destroyed during combat trials.
2656: The first fighters featuring a full cloak enter very limited service. The ships, Strakha class, are used to destroy the Tiger's Claw. Unfortunately for the Kilrathi, the planet where Strakha are produced, Ghorah Khar, rebels against the Empire. The shipyards are destroyed, setting back plans for the ships ten years.
2665: Production of Strakha class ships again begins, in limited numbers. It is not until 2667 that the Confederation will officially confirm the existence of these ships. By 2668, the Strakha is still incredibly rare.
2669: The first pure-fighter variant of the Strakha enters service. The Confederation SHROUD and Blackfish devices enter service. A new variant of the Kilrathi Skipper is tested.
