North Korea Tests Submarine-Launched Strategic Cruise Missiles Amid Rising Peninsula Tensions

The cruise-missile test follows a series of recent military activities on the peninsula. A land-mine explosion in the Demilitarized Zone on September 21 injured three South Korean soldiers, prompting accusations against North Korea. In early October, South Korea successfully flight-tested a domestically developed hypersonic glide vehicle, a capability that Pyongyang has framed as a provocation. North Korea announced a hypersonic intermediate-range missile test on October 3 and launched multiple ballistic missiles on October 12, which it described as a response to the South’s hypersonic test.
