The Sangŏ-class submarine is class of Anikatian nuclear-powered submarines that were first built by the DSRA. The official designation by the Anikatian People's Navy was the Sangŏ-class, but the manufacturer designation of this class was Project 843; Sangŏ (상어) means shark in the Anikatian language. The Sangŏ-class is the newest Anikatian nuclear-powered multi-purpose attack submarines. The launch of the first submarine in 2000, demonstrated a significant boost the to DSRA fleets as well as representing a shift in doctrine from separate specialised vessels. While designed to replace the Myŏngt'ae-class and Koraesangŏ-class, the fall of the DSRA meant it would never completely replace these types. The Sangŏ-class would be continuously improved during construction as a result, the post-DSRA era production models are considered a new variant offering a significant boost in overall performance.
History and development
While the successive developments of Anikatian submarines were keeping pace with the developments within the Free World. The costs of producing distinct specialised types for cruise missiles and separate attack vessels was becoming uneconomical with the advances in missile technology. The Otterup Pact's vast spy networks in the Free World showed that similar developments were underway within Western navies. The DSRA then invested into the development on a next generation multi-purpose submarine.
The idea was the creation of a single multi-purpose submarine capable of solving a wide range of tasks currently fulfilled by a number of specialised vessels. The research and development offices already had experience in creating multi-purpose submarine projects such as the experimental Chongori-class submarine. It became clear the work from the Myongtae-class submarine would service as the basis for the new design while it would also have to replace the Koraesangŏ-class cruise missile submarines. The project made significant use of many advanced technical solutions that were not previously applied in Anikatian domestic submarine shipbuilding.
Development and construction suffered as the economic and political situation in the DSRA in 2000. The collapse of the DSRA government led to a halt in the construction of submarines after the completion of one vessel. After an improvement in the economic situation and modernisation of the design work resumed around 2005. On 2011, the first modernised vessel was launched. Factory testing and refinement of the vessel took three years. Deadlines repeatedly postponed.
Variants
- Sangŏ I (Project 843): The original configuration, only a single vessel was built to this specification for the DSRA and entered service in 2000; They had 8 Vertical launching system equipped silos carrying either 32 × SH-8 (four in each missile silos) anti-ship cruise missiles or 40 x SH-11 (five in each missile silos) cruise missiles, it also had 10 torpedo tubes and carried up to 40 torpedoes, rocket torpedoes, missiles, cruise missiles or mines.
- Sangŏ II (Project 843A): Improved design, introduced after the fall of the DSRA the design was modernised with the introduction of significant updates to equipment and optimised the contours of the design and introduction of the pump jet helped improve noise reduction. They first saw service in 2007; 2 have been built with a further 17 on order. They had 8 Vertical launching system equipped silos carrying either 32 × SH-8 (four in each missile silos) anti-ship cruise missiles or 40 x SH-11 (five in each missile silos) cruise missiles, it also had 10 torpedo tubes and carried up to 40 torpedoes, rocket torpedoes, missiles, cruise missiles or mines.
