Zenit-6U (Argon, 11F645)

Zenit-8 (Oblik) [GDK]
Zenit-6U (Argon) similar

The Zenit-6U, also known as Argon or 11F645, was a soviet optical reconnaissance satellite of the Vostok-based Zenit-family to replace the earlier Zenit-2M (Gektor), Zenit-4M (Rotor), Zenit-4MK (Germes) and Zenit-4MKM (Gerakl) series.

Zenit-6U was both used for both low-altitude, high-resolution missions and higher-altitude area surveillance missions. The satellites consisted of the Vostok-based service and reentry modules and featured an additional maneuvering engine, which was jettisoned before reentry. The spherical reentry module returned both the cameras and the film to earth at the end of the mission. The lifetime of the battery powered spacecraft was typically 12 to 14 days.

97 satellites of this type were launched between 1976 and 1984. The return capsules could be reused several times.
