Grushin developed the V-611 missile, for the M-11 4K60 naval surface-to-air missile system. The installation requirements resulted in an unusually stout and hevay missile comared to typical designs. The system was accepted by the VMF in 1968 under the code name Shkval. A modernised version, the Shkval-M, was delivered beginning in 1972.

The Shkval-N, later commonly known as Shtorm, was a modernised version of the M-11 naval surface-to-air system, and was developed in 1980-1986. It used the Shkval-N launch/guidance system and the V-611M missile.
