The Imgui-class submarine is an Anikatian class of nuclear-powered balistic missile submarines that were built by the DSRA. The official designation by the Anikatian People's Navy is the Imgui-class, but the manufacturer designation of this class was Project 949; Imgui (이무기) refers to a mythical water dragon or sea serpent creature in the Anikatian language. Displacing over of 50,000 tonnes, the Imugi-class vessels are the largest submarines ever built and allow enough space for unparalleled living facilities for the crew especially compared to contemporary DSRA vessels. This allowed the vessel and crew to stay submerged for months on end.

History and development

While the Haema-class submarine was still entering service research and development had begun on the development of a new solid-fuel three-stage intercontinental ballistic missile alongside the modernisations of the liquid-fuelled SKG-15 missile. The design progressed and was approved by the government after a series of successful missile tests showing favourable characteristics in flight distance and throw-weight.

Because of the dimensions of the new SKG-17 missile system a new tactical and technical design was issued by the state to develop a submarine of Project 949, that would be equipped with twenty-four solid-fuel missiles SLG-17s. To accommodate such large missiles a new generation of strategic submarines with a completely innovative layout had to be created.

A programme for a new strategic nuclear missile submarine system was given authorization for development by the DSRA. While development of successful Haema-class submarine was already undertaken the government was keen to maintain and edge and gain any advantage in the Cold War.

Using skills and knowledge acquired from both the Haema and other programmes development of a new class of submarine was given the highest priority due to the long-standing notion of a "SSBN Gap" due to the inaccurate intelligence that the CDI developing a lead in nuclear ballistic missile submarines, with exaggerated estimates that hundreds were available, it was eventually discovered that the gap was entirely fictional.

The result was a massive expansion of the DSRA's own submarine building programmes, which led to the eventual introduction of numerous advanced nuclear ballistic missile submarines while after the Cold War the majority of CDI nations were revealed to only maintain a minimum deterrence of SSBNs.

Variants

• Imgui (Project 949): The baseline configuration, these were nuclear-powered submarines that first saw service in 1987; 4 were built. They had 6 torpedo tubes and carried up to 22 torpedoes or mines. 24 x SKG-17 SLBMs each carrying a warhead consists six to ten multiple independently targeted re-entry vehicles (MIRVs), each rated at 200 kt with a maximum range of 8,250 km. The missile uses stellar inertial guidance to provide a circular error probable (CEP) of 400 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

Units

Following is a list of all 4 Imgui-class submarines built for the DSRA. A total of 10 were originally planned before the fall of the DSRA while a total of 6 were cancelled only one more had been laid down but it was scrapped before completion.
