The crew complement numbered ninety personnel and there were no facilities to launch and retrieve navy helicopters off the stern. The "Slim Net" and "Hawk Skreech" systems were carried as was the "Herkules" hull-mounted sonar fit and a dipping sonar. Displacement was 950 tons under standard load and 1,150 tons under full load. The ship's profile saw the mass of the superstructure contained forward of midships with low-profile funnels aft of this. A forward and rear turret dominated the rest of the silhouette. A main mast was set along the aft section of the superstructure.
Export sales to foreign navies were a way to not decommission all the ships early as well as to create (or further strengthen) ties with foreign governments like that of Ethiopia, India and Syria. The Soviets retained some ships for parts to support these overseas sales. The Indian Navy purchased eleven of the Petya III ships but all have since been sold for scrapping. Vietnam purchased a batch of six and some remain in service (2016). Ethiopia purchased four of the vessels but these are now decommissioned. Syria has two boats on active patrol (Al Assari, Al Hirasa) (2016).
