Kosmos 1894 (Russian: Космос 1894 meaning Cosmos 1894) is a Soviet US-KS missile early warning satellite which was launched in 1987 as part of the Oko programme. The satellite is designed to identify missile launches using optical telescopes and infrared sensors.^[1]

Kosmos 2155 was launched from Site 200/40 at Baikonur Cosmodrome in the Kazakh SSR.^[1] A Proton-K carrier rocket with a DM-2 upper stage was used to perform the launch, which took place at 15:15 UTC on 28 October 1987.^[2][3] The launch successfully placed the satellite into geostationary orbit. It subsequently received its Kosmos designation, and the international designator 1987-091A.^[2] The United States Space Command assigned it the Satellite Catalog Number 18443.^[2][3]

It was operational for about 2 years.^[3]
