South Korea’s president on Tuesday called for stronger air defenses and high-tech stealth drones while the military apologized for failing to shoot down North Korean drones that crossed the border for the first time in five years. South Korea’s military scrambled warplanes and attack helicopters on Monday, but they failed to bring down any of the North Korean drones that flew back home or disappeared from South Korean radars. It raised serious questions about South Korea’s air defense network at a time when tensions remain high over North Korea’s torrid run of missile tests this year. “We have a plan to create a military drone unit tasked with monitoring key military facilities in North Korea. But we’ll advance the establishment of the drone unit as soon as possible because of yesterday’s incident,” President Yoon Suk Yeol said during a regular Cabinet Council meeting. “We’ll also introduce state-of-the art stealth drones and bolster our surveillance capability.” He said that South Korea’s military needs more intensive readiness and exercises to cope with threats posed by North Korean drones.

Kang Shin Chul, chief director of operation at the Joint Chiefs of Staff, said in a televised statement the military feels sorry because of its failure to shoot down the North Korean drones and for causing big public concerns. Kang acknowledged South Korea lacks capacities to detect and strike small surveillance drones with a wingspan of less than 3 meters (9.8 feet) though it has assets to spot and bring down bigger combat drones. Kang said South Korea will establish drone units with various capacities and aggressively deploy military assets to shoot down enemy drones. A front-line county office in South Korea on Tuesday sent emergency text messages notifying residents of a new batch of North Korean drones. But the military later said it was a flock of birds. On Monday, South Korea sent its own surveillance assets, apparently unmanned drones, across the border as corresponding steps against the North Korean drone flights. South Korea’s public confirmation of reconnaissance activities inside North Korea is highly unusual and likely reflects a resolve by Yoon’s government to get tough on North Korean provocations. It was the first time North Korean drones entered South Korean airspace since 2017. The drone flights came three days after South Korea said North Korea launched two short-range ballistic missiles, extending its record testing activities this year. North Korea has touted its drone program, and South Korean officials have previously said the North had about 300 drones. Advanced drones are among modern weapons systems that North Korean leader Kim Jong Un has vowed to procure, along with multi-warheads, underwater-launched nuclear missiles and a spy satellite.

Korea fires warning shots after North drones cross border Earlier Tuesday, North Korea’s state media said Kim called for stronger effort to overcome hardships and challenges facing his country at the start of a key ruling Workers’ Party meeting the previous day. Some experts say Kim will likely use the meeting to reaffirm his resolve to expand his nuclear arsenal and introduce high-tech weapons targeting the U.S. and South Korea while laying out projects to revive pandemic-battered public livelihoods. In Seoul, the South Korean president used the drone incident to hit at his liberal predecessor’s engagement policy with North Korea. Yoon, a conservative who took office in May, said South Korea’s military had conducted little anti-drone training since 2017, when Moon Jae-in was inaugurated. “I think our people must have seen well how dangerous a policy relying on the North’s good faiths and (peace) agreements would be,” he said. Moon’s liberal opposition Democratic Party accused Yoon of shifting his government’s “security disaster” to someone else. Party spokesperson Park Sung-joon called on Yoon to thoroughly disclose what he did when the North Korean drones were flying in South Korean territory. Moon was credited with arranging now-dormant diplomacy on North Korea’s nuclear program, but also faced criticism that his appeasement policy allowed North Korea to buy time and boost its nuclear arsenal despite international sanctions. The North Korean Workers’ Party meeting is expected to last several days, and Kim will likely address issues such as his arms buildup, relations with the United States and the economy in later sessions.

North Korea’s military said Monday its recent barrage of missile tests were practices to attack its rivals’ air bases and warplanes and paralyze their operation command systems, showing Pyongyang’s resolve to counter provocative U.S.-South Korean military drills “more thoroughly and mercilessly.” North Korea fired dozens of missiles and flew warplanes last week, triggering evacuation alerts in some South Korean and Japanese areas, in response to massive U.S.-South Korean air force drills that the North views as an invasion rehearsal. U.S. and South Korean officials strongly condemned the North’s missile launches, saying their drills were defensive in nature. “The recent corresponding military operations by the Korean People’s Army are a clear answer of (North Korea) that the more persistently the enemies’ provocative military moves continue, the more thoroughly and mercilessly the KPA will counter them,” the General Staff of the Korean People’s Army said in a statement carried by state media.

The North’s military said it carried out an important test of a ballistic missile with a special functional warhead missioned with “paralyzing the operation command system of the enemy.” It said it also launched super-large, multiple-launch missiles and tactical ballistic missiles. It didn’t specifically mention a reported launch Thursday of an intercontinental ballistic missile aimed at hitting the U.S. mainland. Almost all other North’s missiles launched last week were likely short-range, many of them nuclear-capable weapons. They place key military targets in South Korea, including U.S. military bases there in striking range. “The KPA General Staff once again clarifies that it will continue to correspond with all the anti-(North Korea) war drills of the enemy with the sustained, resolute and overwhelming practical military measures,” it said. This year’s “Vigilant Storm” air force drills between the United States and South Korea were the largest-ever for the annual fall maneuvers. The drills involved 240 warplanes including advanced F-35 fighter jets from both countries. The allies were initially supposed to run the drills for five days ending on Friday, but extended the training by another day in reaction to the North’s missile tests. On Saturday, the final day of the air force exercises, the United States flew two B-1B supersonic bombers over South Korea in a display of strength against North Korea, the aircraft’s first such flyover since December 2017.

Even before the “Vigilant Storm” drills, North Korea test-launched a slew of missiles in what it called simulated nuclear attacks on U.S. and South Korean targets in protests of its rivals’ other sets of military exercises that involved a U.S. aircraft for the first time in five years. Some experts say North Korea likely aims to use the U.S.-South Korean military drills as a chance to modernize its nuclear arsenal and increase its leverage to wrest greater concessions from the United States in future dealings. U.S. and South Korean militaries have been expanding their regular military drills since the May inauguration of conservative South Korean President Yoon Suk Yeol, who has promised to take a tougher stance on North Korean provocations. Some of the allies’ drills had been previously downsized or canceled to support now-stalled diplomacy on North Korea’s nuclear program and cope with the COVID-19 pandemic.
