• Polet 1; Polyot 1 Spacecraft: Polyot-1. Payload: I-2B s/n 1. Mass: 1,400 kg.

  ASAT interceptor control and propulsion test. Launched by Korolev R-7 because Chelomei's own UR-200 was not yet available. Purpose - elaboration of system providing for the extensive manoeuvring of space apparatuses. Flight was considered a great success. Micro-engine fired 350 times and main stabilizing engine fired 300 times. Orbit given is final orbit after manoeuvres.

• Polet 2; Polyot 2 Spacecraft: Polyot-2. Payload: I-2B s/n 2. Mass: 1,400 kg.

  ASAT interceptor control and propulsion test. Elaboration of systems providing for the extensive manouevring of space apparatuses.
