1963-043A
I-2B was a prototype of the IS satellite with an Isayev engine. Two flight vehicles, No. 102 and 103, were built. I-2B No. 102 was launched as Polyot 1. The I-150 (or I-2B No 102) (Polyot 1) satellite was launched on 1963 Nov 1 by the 11A59 launch vehicle, a special variant of the 8K74A (R-7A) Sputnik class core vehicle with no upper stage. Converted 8K74 ICBMs were used, refurbished at NII-88/Podlipki with a new fairing and adapter and modified systems. Orbital insertion was performed by the Polyot propulsion system. The purpose of the mission was to test the anti-satellite propulsion engine; it was originally planned to use the UR-200 rocket to launch Polyot, but that rocket was behind schedule.
