For the first time in seven years, B-1 Lancers have conducted live munitions drops over South Korea during exercises with the South Koreans. Recently, North Korea has been floating hundreds of balloons filled with trash across the DMZ into South Korea. In response, the South Koreans have fully suspended a 2018 inter-Korean military agreement. The exercises come soon after South Korea deployed new fifth-generation F-35s in response to an upcoming North Korean spy satellite launch.
