The Tolmuksangŏ-class submarine is a class of nuclear-powered balistic missile submarines built by Anikatia. The official designation by the Anikatian People's Navy was the Tolmuksangŏ-class, but the manufacturer designation of this class was Project 960; Tolmuksangŏ (돌묵상어) means basking shark in the Anikatian language.

While the Tolmuksangŏ-class is the latest Anikatian ballistic missile submarine to enter service and intended to replace the existing Haema II-class, Haema III-class and Imgui-classes. They are were designed to be far more cost effective than the preceding Imgui-class and are therefore considerably smaller while increasing operational effectiveness.

History and development

The Tolmuksangŏ-class was intended in part as a less expensive alternative to the massive Imgui-class submarines, whose production run was stopped after just four vessels had been completed. Yet the DSRA still required a large number of new SSBNs to replace the ageing Haema-class submarines. To reduce costs it was proposed to redesign the new ballistic missile submarines by sharing a substantial number of components including some aspects of the hulls with the Sango-class attack submarines.

The Ministry of Defence decided to develop a new solid-fuelled intercontinental ballistic missile after further development of with the SKG-17H stalled. This was done alongside the modernisations of the liquid-fuelled SKG-15 missile. The Tolmuksangŏ-class which was initially slated to carry 14 missiles were able to carry a further four due to the decrease in mass of the new SKG-18 SLBMs over the originally proposed SKG-17H. The new missile uses advanced technology allows it to carry up to 10 hypersonic, individually guided, manoeuvrable warheads with a yield of 100–150 kt each allowing warheads to bypass missile defence systems.

As a result of the collapse of the DSRA regime and wider 2000 Far Eastern financial crisis the programme suffered numerous delays due to reduced funding, the economic turmoil between companies and subcontractors. Despite this, the basic design was substantially revamped underwent a considerable redesign and modernisation most notably was the introduction of the pump jet which replaced the single shaft propeller and helped improve noise reduction. Significant updates were made by the installation of more sophisticated communication, detection and control systems. Along with an enhanced habitability and survivability for the crew.

Variants

• Tolmuksangŏ I (Project 960): The original configuration, only two vessels were built to this specification for the DSRA that first saw service in 2001; They had 6 torpedo tubes and carried up to 24 torpedoes or mines. 18 x SKG-18 SLBMs each carrying a warhead consists six to ten multiple independently targeted re-entry vehicles (MIRVs), each rated at 100-150 kt with a maximum range of 8,300-8,500 km. The missile uses stellar inertial guidance, Astro-inertial guidance along with satellite navigation to provide a circular error probable (CEP) of 340 m. The CEP value is a measure of the accuracy of strike on the target and is the radius of the circle within which half the strikes will impact
• Tolmuksangŏ II (Project 960A): 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 2005; 6 have been built with a further 14 on order. They had 6 torpedo tubes and carried up to 24 torpedoes or mines. 18 x SKG-18 SLBMs each carrying a warhead consists six to ten multiple independently targeted re-entry vehicles (MIRVs), each rated at 100-150 kt with a maximum range of 8,300-8,500 km. The missile uses stellar inertial guidance, Astro-inertial guidance along with satellite navigation to provide a circular error probable (CEP) of 340 m. The CEP value is a measure of the accuracy of strike on the target and is the radius of the circle within which half the strikes will impact
