The unique radar system covers the missile entire effective range, tracing concurrently 15 targets, and assigns six designated targets under intensive EW environment. The gun fire control system detects air and surface targets, performs automatic tracking, and computes firing data. The radar which is used to detect surface targets provides fire control system with designation data for five targets at a time. The corvette is also fitted with active radar jammers and IFF radar. The missile corvette is equipped with the full set of navigation and communication equipment, powerful gas turbine power plant, air-conditioning and ventilation systems to provide efficient operation in any climatic conditions.
