The Koraesango-class submarine was the last purpose built Anikatian class of nuclear-powered cruise missiles submarines that were built by the DSRA.

The official designation by the Anikatian People's Navy was the Koraesango-class, but the manufacturer designation of this class was Project 524; Koraesango (고래상어) means whale shark in the Anikatian language. They are among the largest cruise missile submarines in the world in terms of displacement and length.

History and development

While the Korae-class submarine was still entering service intelligence on CDI naval forces indicated the construction of large aircraft carriers of which the Korae-class even after modernisation, would be insufficient to guarantee the destruction of the CDI carrier groups.

It was clear a new class of cruise missile submarine was to be undertaken. The DSRA leaders knew they could not match the economic spending on surface fleet carriers. The People's Navy was operating only a single small pre-revolutionary fleet carrier while the comparatively small Motyekkoyu-class aircraft carrier was under construction.

Instead, it was considered far more cost effective to invest into cruise missile submarines which would be able to destroy a carrier group with a salvo of 20-24 missiles fired from a submerged and safe position.

The class was to have enhanced stealth, speed and immersion depth on existing designs research from all leading submarine operations was shared for the development of this vessel.

The submarine was to be equipped with the new SH-6 cruise missile system, the design featured a double hull with a two-shaft, two propellers setup. Special care was made to streamline the contours along the entire length of the design.

The vessel featured the use of automatic and remote control system as well as automatic control of emergency systems. The design is equipped with an advanced sonar system and radio system, command and control, space reconnaissance and target designation. Receiving intelligence from satellites or aircraft is carried out in a submerged position in the special antenna.

In the bow and amidships, are the missile silos with 24 placed antiship missile SH-6 they war arranged in groups of three under the large silo doors, on the advanced Koraesango II the number of silos was increased to 30 SH-6 missiles.

The rockets can be fired both in single use or as a salvo. Used as a salvo, the target distribution is carried out in a volley. The SH-6 provides a high probability of hitting and heavily damaging an aircraft carrier and its escort ships.

Variants

• Koraesango I (Project 524): The baseline configuration, these were nuclear-powered submarines that first saw service in 1982; 2 were built. They had 6 torpedo tubes and carried up to 28 torpedoes, and 24 mines. 24 x SH-6 anti-ship cruise missiles which were later replaced with SH-8 missiles.

• Koraesango II (Project 524A): Advanced improved design, with increased length by nearly 13.75 metres and higher displacement allowing greater diving depths, other improvements were new electronic equipment, new sonar and increase in silos allowing up to thirty anti-ship cruise missiles. These were nuclear-powered submarines first saw service in 1985; 10 were built. They had 6 torpedo tubes and carried up to 28 torpedoes, and 24 mines. The 30 x SH-6 anti-ship cruise missiles were later replaced and upgraded with either 30 x SH-8 anti-ship cruise missiles, or with up to 120 x SH-11 (four in each missile silos) greatly improving the combat effectiveness of the type.

Units

Following is a list of all 12 Koraesango-class submarines built for the DSRA. A total of 20 were originally planned before the fall of the DSRA while a total of 8 were cancelled only two had been laid down but they were scrapped before completion.
