Project history

This improved Project 613 could dive deeper and had greater range. The TTZ was reportedly issued in 1952-53. The Balcon-like passive array below the bow was replaced by a larger passive array on the upper part of the bow. The Tamir attack sonar was replaced by an Arktika tracking sonar feeding a torpedo fire control system, Leningrad-633. Many units had small sonar domes on deck forward carrying a sonar intercept array, with underwater telephone above it. Unlike Project 613, this submarine had a deeper bow carrying an extra pair of bow tubes. It appears that production of these boats, a large number of which were planned, was reinstated (with the Project 641) about 1956, then finally stopped a few years later and parts and tooling sold to China. Production in North Korea was apparently unauthorized by the Soviets.

Modernizations

1970, S-350 - under Project 633L: science equipment was installed; - 6 spare torpedoes

1972, S-49; 1986, S-11 - under Project 633RV: 1350/1810t, 78.3x6.70x4.90m, /12kts; armament consisted of 2 - 650 TT (bow, 4 Veter ASuM), 4 - 533 TT (2 bow, 2 stern, Vodopad ASuM)

1978, S-128 - under Project 633KS: 2 bow TTs were modified for launch of Granat CruM
