Summary

COSMOS 1855 (also known as Kosmos-1855) is a military communication satellite launched on June 16, 1987, from the Plesetsk Cosmodrome LC132/1 launch pad using a Kosmos 11K65M launch vehicle. The spacecraft has dimensions of 0.8 meters in length, diameter, and span with a dry mass and launch mass both at 60 kilograms. It is equipped with solar cells and batteries for power and was designed to operate for about six months. Manufactured by NPOPM (NPO Precision Mechanics), this satellite's primary mission was military communication, carrying the Strela-1M Blok 41 No. 4 payload. The satellite has a polyhedral shape with an RCS of 0.6649 and is attributed to the former Soviet Union under unknown ownership.
