"The 'Invincible Shield' drill is aimed at improving the allies' capabilities of attacking North Korea's major military and leadership facilities (if provoked) but also intercepting incoming fighters from the North," the spokesman said as quoted by Yonhap news agency.
According to the spokesman, the combined aerial exercises will kick off on November 4 and will last until November 10. The drills will take place at Osan Air Base in the county of Pyeongtaek, some 40 miles south of Seoul.
"Through the exercise, the three countries will be able to bolster the interoperability of their military arsenals and joint operational capabilities in the event of conflict breaking out on the Korean Peninsula," the spokesman said.
On Wednesday, the South Korean Defense Ministry said that the North had made a significant progress in miniaturization of its nuclear arms and reached a high level of nuclear weapons' power.
