The U.S. has deployed B-1B Lancer bombers to Guam for training with allies and partners in the region, the U.S. military announced this week, raising the possibility that the bombers will once again conduct drills around the Korean Peninsula to deter North Korean weapons tests.

In a press release, the U.S. Indo-Pacific Command stated that multiple B-1B Lancers landed at Andersen Air Force Base on June 3 as part of a “Pacific Air Forces (PACAF) Bomber Task Force (BTF) deployment,” without specifying the exact number of aircraft.
