North Korea tests electronic warfare systems, cluster-bomb missile

SEOUL, April 9 (UPI) -- North Korea said Thursday that it carried out a series of weapons tests this week, including a tactical ballistic missile with a cluster-bomb warhead as well as electromagnetic and other electronic warfare systems.

The tests, conducted from Monday to Wednesday, were part of efforts to assess the performance and battlefield use of several new weapons systems, the North's official Korean Central News Agency said.

KCNA said that its surface-to-surface Hwasong-11Ka missile was tested with a cluster-bomb payload capable of striking targets over a wide area, claiming it could "reduce to ashes" targets spanning roughly 16 to 17.2 acres.

The Hwasong-11 missile, also known as the KN-23, is a highly maneuverable short-range ballistic missile similar to Russia's Iskander.

The report came one day after South Korea's Joint Chiefs of Staff said it detected multiple missile launches on Wednesday from the coastal Wonsan area toward the East Sea. The military also reported the launch of an unidentified projectile from the Pyongyang area on Tuesday.

In addition to the missile tests, North Korea said it conducted trials of an electromagnetic weapon system and carbon-fiber bombs, as well as a mobile short-range anti-aircraft missile system.

The tests were overseen by Kim Jong Sik, a senior official involved in the North's missile development programs.

Kim said the electromagnetic weapon and carbon-fiber bomb are "special assets of strategic nature" that can be combined with various military systems.

Carbon-fiber bombs -- also known as graphite bombs-- are designed to disable electrical grids by dispersing fine conductive filaments to short-circuit power infrastructure, causing widespread outages without physical destruction.

Electromagnetic weapons, meanwhile, emit high-energy pulses that can disrupt or damage electronic systems, including communications networks, radar and computing infrastructure.

KCNA also said engineers conducted a test to measure the "maximum workload" of a missile engine using low-cost materials.

The reported mix of electronic weapons systems and cost-efficient production methods points to ongoing efforts to modernize and expand the North's hybrid warfare capabilities.

The tests came after South Korean President Lee Jae Myung on Monday expressed regret over unauthorized drone incursions into the North.

His remarks drew a rare response from Pyongyang, as Kim Yo Jong, the influential sister of leader Kim Jong Un, described Lee as "frank and broad-minded."

Seoul's Unification Ministry called the exchange a positive signal, saying it represented "meaningful progress toward peaceful coexistence on the Korean Peninsula."

North Korea's first vice foreign minister, Jang Kum Chol, later rejected that interpretation, calling it a "hope-filled dream reading" and insisting the South remains "the enemy state most hostile to the DPRK."

The Democratic People's Republic of Korea is the official name of North Korea.

A South Korean military official said the allies are continuing to track developments in the North's weapons programs.

"We maintain the ability and readiness to overwhelmingly respond to any provocation under a solid South Korea-U.S. joint defense posture," Jang Do-young, public affairs director of the Joint Chiefs of Staff, said at a press briefing Thursday.
