North Korea has launched its latest submarine, with the ceremony attended by leader Kim Jong Un. The Sinpo-C class submarine is the latest and most potent addition to North Korea’s nuclear arsenal. Diesel-electric propulsion is a decades-old technology, but North Korea has radically altered the design, stretching the sail to include some missile launch tubes. This is a huge leap in capabilities for North Korea. All signs indicate that North Korea now intends to modernise and expand its missile submarine fleet.
