The problems of a shipboard installation for the Osa system proved less difficult than that for the army's mobile version. In 1963 all three launcher systems in development at TsKB-34 were in trouble, and the naval project was handed over to TsKB-7 for completion. This was for the Osa-M system, for which TsKB-7 developed the ZIF-122 launcher, capable of handling the heavy 9M33 missile. TsKB-7 began work on the troubled project in 1964. Although the state trials schedule was slipped nearly four years, in the third quarter of 1967 Osa-M trials were finally completed successfully. The system was accepted by the VMF for production. It would be another four years before the Army's version went into production.
