[Yang Nak-gyu's Defence Club] Second Submarine Equipped with SLBM Deployed for Combat

A submarine equipped with submarine-launched ballistic missiles (SLBM) will be delivered to the Navy. It was developed purely with domestic technology as a core force of the ‘Kill Chain’ capable of preemptively striking North Korea.

Jangbogo-III Class Batch-I No. 2 Ship, Anmu Ship

According to the military on the 20th, in the afternoon, Geoje Daewoo Shipbuilding & Marine Engineering will deliver the Anmu submarine (pictured), the second vessel of the Jangbogo-III Batch-I, at the Okpo Shipyard. ‘Batch’ refers to a group of ships built of the same type, with performance improvements made from Batch-I to II to III. The first vessel of the Jangbogo-III Batch-I is the Dosan Ahn Changho, commissioned in August 2021.

Once the Navy acquires the Anmu submarine, it will possess 20 submarines in total: nine 209-class, nine 214-class, and two Jangbogo-III-class. Among these, only the Jangbogo-III-class submarines are equipped with vertical launch systems (VLS) capable of firing SLBMs. They are equipped with six VLS units. The SLBM is one of the Hyunmoo-4 series missiles, known as ‘Hyunmoo 4-4.’

The Jangbogo-III-class is South Korea’s first 3,000-ton class submarine. Unlike the earlier Jangbogo (209)-class and Son Won-il (214)-class submarines, which were built using German technology, the Jangbogo-III was designed and constructed entirely with domestic technology. Although it uses a conventional propulsion system rather than nuclear power, it is equipped with an air-independent propulsion (AIP) system, allowing it to conduct underwater operations for several weeks.

The military has also begun constructing a 3,600-ton medium-sized submarine capable of launching 10 SLBMs. This is the Jangbogo-III Batch-II. When delivered to the Navy in 2027, it is expected to become a core force alongside the three Dosan Ahn Changho-class submarines. The Batch-II is about 5.5 meters longer and approximately 600 tons heavier in displacement than the Batch-I Dosan Ahn Changho-class (83.5 meters, 3,000-ton class). It will carry a crew of about 50.
