North Korea said on Tuesday that it had tested a new ballistic missile with a “super-large warhead,” the most recent development in an arms race with South Korea as the countries vie to introduce weapons of increasingly destructive power.

Two of the new missiles, known as the Hwasong-11Da-4.5, were launched on Monday, each with a dummy warhead that weighed 4.5 tons, the North’s official Korean Central News Agency said. ​Ballistic missiles often carry warheads that weigh less than a ton.

South Korea already has similar missiles that can deliver large warheads. Col. Lee Sung-jun, a spokesman for the South’s military, said the North’s Hwasong-11 series missiles were believed to be capable of carrying payloads of half a ton to 2.5 tons, but that it was “theoretically possible” to modify them to deliver a 4.5-ton payload.
