Sinpo-class submarine
The Sinpo-class submarine (Korean: 신포급 잠수함), also called the Gorae class (고래급; lit. whale) or Pongdae class (봉대급), is a new class of submarine produced in North Korea. Only one submarine has been observed in service, the 8.24 Yongung. It is the largest submarine designed and built for the Korean People's Navy.
The design may be influenced by older Yugoslav designs such as Heroj and Sava. There has been speculation the design is influenced by modern Russian submarines of the Kilo-class, or Golf-class submarines, but the submarine is significantly smaller than these designs.
If the design is successful, the Sinpo class could replace the aging Romeo-class submarines. However, it is possibly a one-off experimental submarine as the Korean People's Navy has built previously.
Satellite images suggest the presence of an opening on the conning tower indicating the presence of a launch tube for one or two missiles.
In August 2016, during the annual joint US-South Korea military exercise, a submarine presumed to be this one launched what is believed to be a Pukguksong-1 (KN-11) ballistic missile into the Sea of Japan. North Korea's first released pictures of the submarine associated it with the test of the KN-11 missile.
The only submarine of this class is named 8.24 Yongung ("August 24 Hero"), with pennant number 824, named after the DPRK's first successfully launched submarine-launched ballistic missile (SLBM) from a submarine on 24 August 2016.
On 19 October 2021, the 8.24 Yongung conducted a launch of an SLBM apparently based on the Hwasong-11A (KN-23), later identified as Hwasong-11S. On 14 March 2023, two cruise missiles were fired as part of a launching drill.
As of May 2025, the 8.24 Yongung is docked alongside the Hero Kim Kun Ok at Sinpo South Shipyard.
