The Ch'ŏngŏ-class submarine is a class of diesel-electric submarine built in the DSRA. The official desgination by the Anikatian People's Navy was the Ch'ŏngŏ-class, but the manufacturer designation of this class was Project 514; Ch'ŏngŏ (청어) means herring in the Anikatian language.
It is mainly intended for anti-shipping and anti-submarine operations in relatively shallow water. The later Ch'ŏngŏ II class would be continuously improved during construction, as a result, the final production models have superior acoustic performance. Some later vessels have undergone a series of updates including the insertion of a new hull section with an air-independent propulsion system equipped with Stirling engines.
They remain in service with the Anikatian Navy and have been exported to many Otterup Pact allies and other nations such as Rodarion who operates the largest fleet outside of Anikatia.
History and development
Realising the rapidly approaching obsolescence of the Tarango-class submarines along with an increase in research and develop in the submarine technologies such as sonar acoustic field detection. Anikatian designers began development of quieter designs became a high priority over redundancies and maneuverability.
Since efforts to improve the Tarango-class submarine, failed as the design had reached the limits of its developmental pathways it was decided to create a brand new ship. The new vessel was designed for anti-shipping and anti-submarine warfare while implementing and highly streamlined teardrop shaped hull which incorporates a hydro-dynamically efficient shaped sail, four diving planes and a single large shaft. Which was allowed for the optimal combination of a low noise, hard to detect, but balanced in armament and speed.
As production continued the type was improved and some Ch'ŏngŏ II vessels have undergone a series of updates including the insertion of a new hull section with an air-independent propulsion system equipped with Stirling engines. The use of this systems allows the submarine to operate at high speed on the powerful diesel power systems and then switch to the air-independent propulsion system for silent slow cruising, staying submerged for weeks without surfacing and with no exhaust heat.
The system is also said to be vibration-free, extremely quiet and virtually undetectable and has been implemented on later model Ch'ŏngŏ submarines and will be a standard system on the new Kodungo-class submarines.
Variants
- Ch'ŏngŏ I (Project 514): The baseline configuration, these were diesel-electric attack submarines that first saw service in 1976; 26 were built. They had 6 torpedo tubes and carried 20 torpedoes, anti-ship missiles, or mines.
- Ch'ŏngŏ II (Project 514A): Improved design, with increased length by 7.5 metres and higher displacement allowing greater diving depths, other improvements were new electronic equipment, improved sonar, new larger improved 7 bladed propeller, 43 have been built. They had 6 torpedo tubes and carried 22 torpedoes, anti-ship missiles, cruise missiles, surface to air missiles or mines. Some later DSRA production Ch'ŏngŏ II's were fitted with an air-independent propulsion system.
Units
Following is a list of the 60 submarines built.
Operators
Most saw service in the Anikatian People's Navy. Ch'ŏngŏs were also built for the Saarland Naval Flotilla, Goredemabwan Naval Force, People's Navy and the Papal Navy.
Anikatian Navy - 32 units consisting of 16 Ch'ŏngŏ I's along with twelve Ch'ŏngŏ II's active with a further 4 Ch'ŏngŏ I's and 2 Ch'ŏngŏ II vessels in reserve or undergoing modernisation and refits.
- Template:Country data Saarland Saarland Naval Flotilla - 6 units consisting of three Ch'ŏngŏ I's along with three Ch'ŏngŏ II's the earlier vessels are being updated and modernised.
- Template:Country data Goredemabwa Goredemabwan Naval Force - a single Ch'ŏngŏ I
- Kolenomai People's Navy - three Ch'ŏngŏ I's
- Template:Country data Hornatyia Royal Hornatyian Navy - 5 units consisting of two Ch'ŏngŏ I's along with three Ch'ŏngŏ II's the earlier vessels are being updated and modernised.
- File:Flag of Rodarion.png Papal Navy - 12 units all Ch'ŏngŏ II models.
- Template:Country data Minnysota Arkian Navy - 9 units all Ch'ŏngŏ II models.
- Anikatian People's Navy (passed on to successor states)
