North Korea test-fires 2 more missiles as US sends carrier

SEOUL

A nuclear-powered U.S. aircraft carrier and its battle group began exercises with South Korean warships on Monday, hours after North Korea fired two short-range ballistic missiles in an apparent protest of the allies’ expanding drills.

The seventh missile test this month underscored heightening tensions in the region as both the North’s weapons tests and the U.S.-South Korea joint military exercises have intensified in a cycle of tit-for-tat.

The launches may have been timed for the arrival of the USS Nimitz and its strike group, including a guided missile cruiser and two destroyers, which escorted the carrier and engaged in air defense exercises with South Korean warships in waters near Jeju island.

Jang Do Young, a South Korean navy spokesperson, said the drills were aimed at sharpening joint operational capabilities and demonstrating the U.S. commitment to defend its ally with the full range of options, including nuclear, in face of the North’s “escalating nuclear and missile threats.” The Nimitz strike group was expected to arrive in the South Korean mainland port of Busan on Tuesday.

South Korea’s Joint Chiefs of Staff said the two North Korean missiles were fired from a western inland area south of the North Korean capital of Pyongyang from around 7:47 a.m. to 8 a.m. and traveled around 370 kilometers (229 miles) before landing at sea. Japan’s military said the missiles flew on an irregular trajectory and reached a maximum altitude of 50 kilometers (31 miles) before landing outside Japan’s exclusive economic zone.

Japan has previously used the term to describe a North Korean solid-fuel missile apparently modeled after Russia’s Iskander mobile ballistic system, which is designed to be maneuverable in low-altitude flight to better evade South Korean missile defenses. North Korea also has another short-range system with similar characteristics that resembles the U.S. MGM-140 Army Tactical Missile System.

Japanese Chief Cabinet Secretary Hirokazu Matsuno said North Korea may dial up its testing activity further with more missile launches or even conducting its first nuclear test since September 2017.

The South Korean and Japanese militaries denounced the latest launches as serious provocations threatening regional peace and violating U.N. Security Council resolutions and said they were working with the United States to analyze the missiles further.

The United States and South Korea completed their biggest springtime exercises in years last week, which had included both computer simulations and life-fire field exercises. But the allies have continued their field training in a show of force against North Korea’s expanding nuclear arsenal and belligerent threats of nuclear conflict.

North Korea had also fired a short-range missile when the USS Ronald Reagan and its battle group arrived for joint drills with South Korea in September, which was the last time the United States sent an aircraft carrier to waters near the Korean Peninsula.

North Korea has launched more than 20 ballistic and cruise missiles on 11 occasions this year as it tries to force the United States to accept its nuclear status and negotiate a removal of sanctions from a position of strength.

They weapons tested this month included an intercontinental ballistic missile and a series of short-range missiles intended to overwhelm South Korean defenses as North Korea tries to demonstrate an ability to conduct nuclear strikes on both South Korea and the U.S. mainland.

The North last week carried out what it described as a three-day exercise that simulated nuclear attacks on South Korean targets.

The country's leader Kim Jong Un has condemned the U.S.-South Korean joint military drills as invasion rehearsals. The allies say the exercises are defensive in nature.

The tests also included a purported nuclear-capable underwater drone that the North claimed can set off a huge “radioactive tsunami” and destroy naval vessels and ports. Analysts were skeptical about such claims or whether the device presents a major new threat, but the tests underlined the North’s commitment to expand its arsenal.

North Korea, following some of its ballistic and cruise missile tests this month, also claimed that those weapons were tipped with mock nuclear warheads that detonated 600 to 800 meters (1,960 to 2,600 feet) above their sea targets. communicating them as heights that would maximize damage.

North Korea already is coming off a record year in weapons testing, launching more than 70 missiles in 2022. It had set into law an escalatory nuclear doctrine that authorizes pre-emptive nuclear strikes in a broad range of scenarios where it may perceive its leadership as under threat.

“It appears North Korea might be practicing, or signaling that it’s practicing, the use of nuclear strikes, both preemptive and retaliatory, in a range of scenarios that are authorized in its nuclear doctrine,” said Duyeon Kim, a senior analyst at the Center for a New American Security.

“The problem is that continued testing helps Pyongyang perfect its technology, strengthen its nuclear weapons capability that threatens South Korea and Japan, increase the likelihood of miscalculation that could lead to inadvertent conflict, and accumulate political leverage ahead of future diplomatic talks with Washington.”

Following the North’s announcement of the drone test on Friday, South Korea’s air force released details of a five-day joint drill with the United States last week that included live-fire demonstrations of air-to-air and air-to-ground weapons.

The air force said the exercise was aimed at verifying precision strike capabilities and reaffirming the credibility of Seoul’s “three-axis” strategy against North Korean nuclear threats — preemptively striking sources of attacks, intercepting incoming missiles and neutralizing the North’s leadership and key military facilities.
