A submarine-launched ballistic missile (SLBM) is a ballistic missile capable of being launched from submarines. Modern variants usually deliver multiple independently targetable reentry vehicles (MIRVs) each of which carries a nuclear warhead and allows a single launched missile to strike several targets. Submarine-launched ballistic missiles operate in a different way from submarine-launched cruise missiles.
The two new North Korean submarines could be a modified Soviet-made Romeo-class diesel/electric submarine also known as Sinpo-C that was revealed on North Korean TV on July 2019 and a new North Korean design submarine. According to open-source information, submerged displacement of the Sinpo-C will be from 1,650 to 2,000 tons with a length of 65 m and an estimated beam measurement of 6.5 meters.
The Sinpo-C could be armed with Pukkuksong-1 KN-11 or Pukguksong-3 (KN-26) submarine-launched ballistic missiles (SLBM) which has an estimated range of 1,900 km. North Korea first tested the Pukguksong-3 on October 2, 2019.
According to a U.S. report, North Korea has 40 SANG-O 37-meter Class special operations midget submarines, 33 YUGO 20-meter Class special operations midget submarines, and ten YONO 29-meter submarines. The KPN also can deploy 20 Romeo-class attack submarines against surface ships.
Citing the U.S. report, North Korea’s possession of nuclear weapons and the missiles to transport it up to 9,650 km makes it a threat to US forces stationed in Korea, Japan, Alaska, or even the west coast of the continental United States. Even more concerning was the DPRK’s first successful test launch of a KN-11 missile from a submarine on 23 January 2015 since, in the near future, the North Korean submarines could silently move closer to their targets before launching a nuclear missile that would give the US less warning time.
