Cosmos 2290

Orlets-2 or Yenisey was an improved Orlets-1 film return reconnaissance satellite with 22 small return capsules. Following evaluation of flight trials in April-May 1977 it was concluded that the Yantar-2K was not capable of providing strategic warning of attack. Therefore three additional variants were developed, one of them the wide-spectrum detail and survey satellite Orlets. Orlets featured a panoramic camera and drew on features of an existing draft project designated Yantar-6K. The redesigned spacecraft was expandable, with Phase 1 (Orlets-1) being launched by the Soyuz-U2 launch vehicle, equipped with 8 film return capsules and having a design life of 60 days.
