SEOUL (Reuters) -North Korea said it successfully tested a new tactical ballistic missile on Monday capable of carrying a 4.5-ton super-large warhead, state news agency KCNA reported on Tuesday.
A day earlier, South Korea reported the launch of two ballistic missiles by North Korea and said the second likely failed soon after launch, blowing up in flight over land.
KCNA made no mention of the second missile.
It said the test of the new tactical ballistic missile, named Hwasongpho-11 Da-4.5, was conducted with a simulated heavy warhead to verify flight stability and accuracy.
It did not elaborate on the nature of the simulated warhead.
The country's Missile Administration will conduct another launch of the same type of missile in July to test the "explosion power" of the super-large warhead, KCNA said in a rare disclosure of a future missile launch plan.
The Hwasongpho-11, or Hwasong-11, is a series of short-range ballistic missiles (SRBM) developed by the North that are otherwise known as KN-23 and KN-24.
South Korea's military said on Monday the first of the two missiles launched by the North appeared to be a KN-23 that flew about 600 km (373 miles).
The KN-23 is likely the missile that North Korea has supplied to Russia and was used in the war against Ukraine, according to Ukrainian authorities who examined debris from missiles launched by Russia since December.
North Korea and Russia deny any arms trade, but their ties have rapidly developed since their leaders met in September in Russia pledging closer military cooperation.
Russian President Vladimir Putin and North Korean leader Kim Jong Un met again in Pyongyang in June and signed a pact on a Comprehensive Strategic Partnership that included a mutual defence agreement.
South Korean officials have said North Korea's recent short-range ballistic missile launches may be intended to show its wares to potential buyers.
The second missile launched on Monday flew about 120 km, the South Korean military said. Given the trajectory and the location of the launch near the west coast, the missile likely fell inland in North Korea, South Korea's military said.
North Korea has raced to develop a range of ballistic missiles in recent years, which it names with the Hwasong identifier, including its intercontinental ballistic missiles (ICBM). Hwasong is Korean for Mars.
On Tuesday, KCNA reported the North's ruling Workers' Party Central Committee concluded four days of policy meetings led by its leader Kim.
The report said Kim highlighted the progress made in the industrial and agricultural sectors in the first half of the year and presented goals and strategy for the second half.
In a departure from usual reporting on his fiery remarks on arms development and anti-U.S. struggle at similar meetings, KCNA made scant mention of any discussion on defence or foreign policy, only saying Kim gave directions for its armed forces.
