It appears that North Korea is trying to advance their ballistic missile technology to include hypersonic capabilities:

North Korea fired what appeared to be an intermediate-range ballistic missile (IRBM) into the East Sea on Tuesday, the South Korean military said, in its third ballistic missile launch of the year.

The Joint Chiefs of Staff (JCS) said in a message to reporters that it detected a missile presumed to be intermediate-range class fired from the Pyongyang region at 6:53 a.m. and the missile flew about 600 kilometers before landing in the East Sea.

Military officials suspect the North may have test-fired an intermediate-range missile equipped with a hypersonic warhead to test the performance of its delivery system following an engine test last month.

On March 20, Pyongyang said it successfully conducted a ground jet test of a solid-fuel engine for a new type of intermediate hypersonic missile.

“North Korea appears to have put a hypersonic warhead on top of the delivery system used in the engine test last month,” a senior military official said on the background.
