Orlets-1 was developed after the Yantar-2K satellite was deemed incapable of providing strategic warning of attack. It drew on features of an existing draft project called Yantar-6K. Equipped with a wide-spectrum panoramic camera and carrying eight film return capsules, Orlets-1 had a design life of 60 days.<ref name="NSSDC" /> After completing its mission, the satellite was detonated in its orbit.<ref name="Gunter/Orlets-1" />
