OSAN AIR BASE, South Korea — The United States on Tuesday sent nuclear-capable supersonic bombers streaking over ally South Korea in a show of force meant to cow North Korea after its recent nuclear test and also to settle rattled nerves in the South.
The B-1B bombers, escorted by U.S. and South Korean jets, were seen by an Associated Press photographer as they flew over Osan Air Base, which is 75 miles from the border with North Korea, the world’s most heavily armed. The bombers were likely to return to Andersen Air Force Base in Guam, without landing in South Korea.
Such flyovers are common during higher-than-normal animosity on the Korean Peninsula, which is technically in a state of war as there has never been a peace treaty to end the 1950-53 Korean War.
South Korea does not have nuclear weapons and relies on the U.S. “nuclear umbrella” as a deterrent to North Korea. Washington also stations more than 28,000 troops in the South.
North Korea is keenly aware of the U.S. presence on the peninsula and of what it considers the U.S. nuclear threat. It uses such flyovers and the American military influence in the South in its propaganda as proof of U.S. hostility that it claims as the reason it needs a nuclear bomb program.
“The United States and (South Korea) are taking actions every day to strengthen our alliance and respond to North Korea’s continued aggressive behavior,” Gen. Vincent Brooks, commander of U.S. Forces Korea, said in a statement.
Last week’s nuclear test, the North’s fifth, was its most powerful test to date. Pyongyang’s claim to have used “standardized” warheads in the detonation makes some outsiders worry that it is making headway in its push to develop small, sophisticated warheads that can be put on missiles that can reach the U.S. mainland.
After the test, the North’s nuclear weapons institute said it will take unspecified measures to further boost its nuclear capability, which analysts said hinted at a possible sixth nuclear test.
South Korea’s Defense Ministry spokesman Moon Sang Gyun said Monday that South Korean and U.S. intelligence authorities believe North Korea has the ability to detonate another atomic device at any time at one of its tunnels at its main Punggye-ri nuclear test site, where the five previous atomic explosions took place.
Moon refused to say what specific evidence pointed to another possible nuclear test. But the South’s Yonhap news agency, citing unidentified Seoul government sources, reported Monday that there were signs the North had finished test preparations at one tunnel that has never been used.
Seoul, Washington and their allies have vowed to apply more pressure and sanctions after the test, the second this year.
