Outsiders doubt North Korea’s claim of new missile with ‘super-large warhead’

SEOUL, South Korea — North Korea said Tuesday that it had test-fired a new tactical ballistic missile capable of carrying “a super-large warhead,” a claim quickly disputed by South Korean officials and experts who say the North most likely fabricated a successful test to conceal a botched launch.

It’s the second time that South Korea has questioned North Korea’s claim on the development of new weapons in recent days, as the rivals are locked in heightened animosities over the North’s testing activities.

The North’s official Korean Central News Agency said that Monday’s test involved the Hwasongpho-11 Da-4.5 missile, which can carry a 4.5-ton-class warhead. It said the test was meant to verify the weapon’s flight stability and hit accuracy at the maximum range of 310 miles and the minimum range of 55 miles.

The test apparently refers to the two ballistic missile launches that South Korea said North Korea performed Monday.

Joint Chiefs of Staff spokesperson Lee Sung Joon said at a briefing later Tuesday that the second North Korean missile was found to have fallen on an uninhabited area near Pyongyang, the North’s capital. He said he could find few previous test-launches by North Korea that have aimed at ground target sites.

“Regarding the North Korean assessment, we’re weighing a possibility of deception,” Lee said.

The South Korean military has said the second North Korean missile possibly traveled abnormally during the initial stage of its flight. It said if the missile exploded, its debris would most likely have scattered on the ground.

The KCNA dispatch did not say from where it launched the new missile and where it landed. Unlike previous weapons tests, North Korea also did not publicize any photos of Monday’s test. The fact that it tested both the missile’s maximum and minimum ranges suggested North Korea performed two launches.

KCNA, citing North Korea’s Missile Administration, reported that North Korea will test-fire the missile again later in July to verify the performance of its simulated warhead at the medium range of 155 miles.

Some experts say that test-firing missiles at ground targets could be related to efforts to test how powerful warheads are to destroy underground bunkers and structures.

But Shin Jongwoo, a Seoul-based military expert, said the lack of any photos of the launches means it is highly likely that the North is trying to deceive outsiders to cover up Monday’s failed launches. He said North Korea most likely launched an existing missile on Monday, not the new missile as it claimed.

Yang Uk, an analyst at the Asan Institute for Policy Studies, said that Monday’s tests reflected North Korea’s push to acquire a variety of conventional weapons. But he also said if North Korea truly succeeded in hitting a ground target, it probably would have already published related images to brag about its achievements as it has done in the past.

Since 2022, North Korea has sharply accelerated weapons testing activities to enlarge its nuclear arsenal. The North Korea-claimed ranges of the newly tested missile imply that it targets South Korea. Experts say North Korea would ultimately want to use an expanded weapons arsenal to increase its leverage in future diplomacy with the U.S.

On June 26, North Korea launched what it called a new multiwarhead missile in the first known test of a developmental weapon aimed at penetrating its rivals’ missile defenses. North Korea said the launch was successful, but South Korea dismissed the North’s claim as a deception to cover up a failed launch. South Korea said the weapon blew up, sending debris in the waters off the North’s east coast.

Also Tuesday, South Korea held live-fire drills near the heavily fortified land border with North Korea, the first of their kind since the South suspended a 2018 agreement with the North aimed at reducing front-line military tensions in early June. Last week, South Korea conducted similar firing exercises near its disputed western sea boundary with North Korea.

The back-to-back South Korean exercises could prompt North Korea, which also said it will no longer be bound by the 2018 pact, to take provocative steps at border areas.

Meanwhile, during a four-day key ruling party meeting that ended Monday, North Korean leader Kim Jong Un claimed that his country’s economic and food situations have improved and presented officials with tasks to maintain steady economic development, KCNA said Tuesday. It did not mention whether the meeting discussed any security or foreign policy issues.
