The Myŏngt'ae-class submarine is class of Anikatian nuclear-powered submarines that were built by the DSRA. The official designation by the Anikatian People's Navy was the Myŏngt'ae-class, but the manufacturer designation of this class was Project 738; Myŏngt'ae (명태) means pollock in the Anikatian language. The Myŏngt'ae-class represented a leap in steel constructed submarines along with advancements that allowed the submarine to be quieter and deeper diving than previous steel Anikatian design.

The launch of the first submarine in 1987, demonstrated a significant boost the to DSRA fleets as the submarine class now implemented many of the innovative features of previous experimental submarines while being considerably more manageable to assemble than the titanium designs allowing for greater production numbers. While designed to replace the Songŏryu-class and work alongside the Kalmaegi-class submarines, it would never completely replace the Songŏryu. The Myŏngt'ae-class would be continuously improved during construction, as a result the final production models superior acoustic performance and remain in service with the Anikatian Navy.

History and development

Despite the production of the highly successful Kalmaegi-class submarine, it's expensive and complex design limited its production numbers and intelligence gathered from its spy networks in the Free World revealed that despite significant advances the DSRA SSN fleet still had serious shortcoming compared against the CDI forces. The leader of the DSRA were eager to overcome this "Submarine Gap" and develop of an all new submarine based on experience and research gained from the advanced production multi-purpose titanium hulledKalmaegi-class submarines.

The new vessel would try to preserve the deep diving depths and also reduces the magnetic field of the Kalmaegi-class vessels. While being a more cost effective design which was intended to replace the large numbers of Songoryu-class submarines which were still the mainstay of the navy at that time. The new design made use of high-quality alloy steel which allowed for performance close to the titanium-hulled submarines but at far more economical and manageable to construct. To simplify the installation of the equipment, the vessels were designed using block units, which allowed the transfer of significant quantities of work from the restrictive compartments of the submarine directly to the workshop.

After the installation of the block units into the hull of the vessel and connected to the main cables and pipelines ship systems. To help with noise reduction, a two-stage damping system was used. Which used rubber-pneumatic shock absorbers to isolate noise. In addition to reducing the overall noise submarine, such a system can reduce the effects of underwater explosions on the equipment and the crew. The submarine is equipped with two tip-thruster and retractable bow hydroplanes with flaps and the hull featured heavily streamlining to reduce noise from hydrodynamic turbulence.

Variants

• Myŏngt'ae I (Project 738): The baseline configuration, these were nuclear-powered submarines that first saw service in 1985; 8 were built. They had 8 torpedo tubes and carried 40 torpedoes, mines or other tube-launched weapons like cruise missiles.
• Myŏngt'ae II (Project 738A): Improved design, with increased length by nearly 7 metres and higher displacement allowing greater diving depths, other improvements were new electronic equipment, new sonar, new larger improved 8 bladed propeller, they first saw service in 1988 ;14 were built. They had 8 torpedo tubes and carried 40 torpedoes, rocket torpedoes, mines or other tube-launched weapons like cruise missiles.
