Kosmos 772 (Russian: Космос 772 meaning Cosmos 772) was an uncrewed military Soyuz 7K-S test. It was an unsuccessful mission as only one transmitter worked. Only the 166 MHz frequency transmitter operated, all of the other normal Soyuz wavelengths transmitters failed.  The experience from these flights were used in the development of the successor program Soyuz spacecraft the Soyuz 7K-ST.
