South Korea, US, Japan to stage anti-submarine drills amid North Korea tension

The naval forces of South Korea, the US and Japan will stage their major trilateral anti-submarine exercises for the first time in five years on Friday, amid tension over North Korea's recent series of missile tests.

The drills will be held in international waters off the Korean peninsula's east coast, just a day after North Korea fired two ballistic missiles toward its east coast and US Vice President Kamala Harris visited Seoul and the heavily fortified border between the two Koreas.

"The exercises are designed to improve their capability to respond to increasing North Korean submarine threats, including its submarine-launched ballistic missiles (SLBM) at a time when it consistently poses nuclear and missile threats with a series of ballistic missile tests," the South Korean navy said in a statement.

The one-day drills are a flagship maritime training that has not been conducted since 2017 becausethe former progressive South Korean government sought to improve inter-Korean relations and facilitate denuclearsation talks between Pyongyang and Washington, which have stalled since 2019.

Under the programme, the three countries' navies will track down a mock North Korean submarine while exchanging information with each other, a South Korean military official said.

The exercises will bring together the USS Ronald Reagan aircraft carrier, the 9,800-ton guided missile cruiser USS Chancellorsville, the 6,900-ton Aegis-equipped destroyer USS Barry, South Korea's 4,400-ton destroyer Munmu the Great and Japan's 5,100-ton tanker Asahi, among other warships, the South Korean navy said.

The drills came days after a US-based think tank said North Korea may be preparing to launch a new submarine believed to be capable of firing ballistic missiles, citing commercial satellite imagery.

South Korea's military has also detected signs that the isolated country might be gearing up for an SLBM test, Yonhap news agency reported on Saturday.
