The Kaelon warship was a type of warship used by the Kaelons during the 24th century. These starships were capable of landing on planetary surfaces.
In 2367, following a request of political asylum to the crew of the USS Enterprise-D from the Kaelon scientist Timicin, two Kaelon warships approached the Enterprise from the surface of Kaelon II, taking a standard attack posture with staggered approach vectors. Their orders were to open fire on the Enterprise if it attempted to leave orbit. The three ships remained in a stalemate until Dr. Timicin's request for asylum was withdrawn. (TNG: "Half a Life")
