The Tarangŏ-class submarine is a class of diesel-electric patrol submarines that were built in the DSRA. These were the first Anikatian post-war submarines built by the new socialist state. The official desgination by the Anikatian People's Navy was the Tarangŏ-class, but the manufacturer designation of this class was Project 243; Tarangŏ (다랑어) means tuna in the Anikatian language.

The Tarangŏ-class was a double-hulled submarine and the first Anikatian design to use a streamlined hull torpedo-like hull which offered it comparable performance and armament to most contemporary designs. However, despite the advanced hull, low-noise variable-pitch propellers, and the use of vibration dampening its three screw design made it noisier than most Western designs.

The Tarango-class was effectively obsolete by the time the last submarine was launched. The Anikatian Navy retired its last Tarango's between 1992 and 2001, units were scrapped and disposed of for museum purposes.

History and development

Unlike the earlier vessels, this new design was maximized for underwater speed by fully streamlining the hull. The Tarangos' design was based on the extensive research and development in submarine designers which sought to shift the dynamic so that surface performance characteristics would be completely subordinated to high submerged speed and agility. The bulk of research on hydrodynamics led to a number of experimental programs to determine what hull design would offer the best dynamics for submerged operations.

While the fastest designs were single screw aft of the rudder and stern the navy opted for a unique three screw design with one aft and two side mount, this offered far greater maneuverability and safety because of the redundancies. However, it did slightly lower speeds and increase noise compared to contemporary single screw designs.

Variants

• Tarangŏ I (Project 243): The baseline configuration, these were diesel-electric patrol submarines that first saw service in 1955; 27 were built. They had 8 torpedo tubes and carried 22 torpedoes.
• Tarangŏ II (Project 243A): Improved design, with a new bow sonar dome in the keel and a hydrophone antenna over the torpedo tubes, 20 were built.

Tarangŏ III

• Tarangŏ III (Project 243G): 8 vessels of Tarangŏ I class were updated to Tarangŏ II specification and converted to carry a cruise missile system making it a SSG. These boats had two missile tubes behind the sail. This setup did not handle well, and the missile launchers caused stability problems and water flow around the missile fittings was very noisy. However the provided key experience and development towards later cruise missile submarine designs.

Tarangŏ IV

• Tarangŏ IV (Project 243B): 5 Tarangŏ I submarines were converted to carry ballistic missiles for testing development. Initially it was fitted with two SKG-4 SLBM's but later conversions were fitted with SKG-8 SLBM and finally all vessels were updated with the new SKG-9 SLBM. It was classed as a SSB. They carried two missiles fitted in the rear of the large sail behind the bridge. They could only be fired with the submarine surfaced and the missile raised above the sail but the submarine could be underway at the time.
