The Chŏngŏri-class submarine is an Anikatian highly advanced experimental single-ship class nuclear-powered submarine built by the DSRA. It was a essentially all new submarine based on a modified Songŏryu III hull.
The official designation by the Anikatian People's Navy was the Chŏngŏri-class, but the manufacturer designation of this class was Project 335; Chŏngŏri (정어리) means sardine in the Anikatian language.
It introduced a number of highly innovative features, it was the first Anikatian vessel to be built with a titanium hull allowing far greater operating depths than previous submarines. In addition, it introduced the use of a special escape capsule within the sail that allowed the crew to evacuate the ship in the event of an accident or emergency. The vessel remains one of the deepest diving submarines in the world.
History and development
It was developed as an experiential single vessel to trial new technology for future nuclear submarines. Despite its prototype and experimental status, it was fully combat-capable. It was the first use of titanium on an Anikatian submarine which significantly reduced the weight of the vessel. Structurally the submarine was a was double hull design, the inner hull was titanium, which allowed it to achieve extreme an operating depth far greater than that of all but the most advanced contemporary submarines.
Carefully consideration was taken to crafting the exterior contours of the light-weight hull to reduce hydrodynamic resistance. As a result, the lightweight teardrop shaped hull was lined with rubber coating that enhanced the stealthy characteristics of the craft. The pressure hull was composed of seven compartments with the second and third protected by stronger forward and aft bulkheads creating a "safety zone" in case of an emergency. The experience gained in the creation of this submarine, would later be put to use in creating a series production of the deep diving titanium-hulled Kalmaegi-class submarine.
It also saw the pioneering use of an escape capsule in an Anikatian submarine. Which was fitted in the sail above these compartments to enable the crew to abandon ship in the event of an underwater emergency, the design saw the introduction of other advanced innovations including the automation of many systems allowing for smaller crews.
Variants
- Chongori (Project 335): The experiential titanium hulled single vessel nuclear-powered submarine that first launched in 1973 but did not enter service until 1974; only a single vessel of this type was built. It had 6 torpedo tubes and could carry up to 24 torpedoes, mines or other tube-launched weapons like cruise missiles. The only vessel was laid up in 2004 and has once against entered active service after being laid up for over ten years. It underwent extensive repair, refit and modernisation before reentering service.
