TOKYO - Tensions between the United States and North Korea have been intensifying behind the scenes, despite the recent spotlight on former President Donald Trump. On April 15th, two U.S. Air Force B-1B bombers participated in a joint training exercise with the South Korean Air Force over South Korean airspace.
Following the exercise, North Korea’s Ministry of Defense issued a statement condemning the operation as a "reckless display of force," directly criticizing the B-1B bombers for "unilaterally raising military tensions."
The B-1B is known for its ability to carry the largest payload of bombs and missiles among U.S. bombers. Special commentator Nobuyuki Nose of Fuji TV explained that the B-1B can be equipped with up to 24 JASSM-ER missiles, each capable of striking targets across North Korea from areas around South Korea. After destroying air defense systems with these missiles, the aircraft could enter enemy airspace at low altitude and use a Sniper Pod targeting device to accurately deliver bombs and missiles onto nuclear or submarine facilities, potentially enabling pinpoint strikes.
After completing the joint exercise, the two B-1B bombers landed at Misawa Air Base in Aomori Prefecture. Later, FNN cameras confirmed the arrival of two additional B-1B bombers. The deployment of four B-1B bombers to Japan is extremely rare. North Korean media on April 26th criticized the move, stating that the notorious "swans of death" had now established a presence in Japan.
The U.S. show of force appears to be a response to North Korea’s recent military activities. At the start of 2025, North Korean leader Kim Jong Un inspected a facility lined with uranium enrichment equipment essential for nuclear weapons production. In March, North Korean media reported that Kim had also visited the construction site of a nuclear-powered strategic guided missile submarine. In April, his sister Kim Yo Jong publicly rejected the idea of North Korea’s denuclearization.
Nose pointed out that if North Korea manages to equip a nuclear-powered submarine with strategic missiles and approach the U.S. mainland, it could deliver a serious blow to American security. North Korea’s repeated provocations likely contributed to the unusual deployment of four B-1B bombers to Japan.
Meanwhile, the U.S. Navy’s expeditionary mobile base ship Miguel Keith, which had been undergoing maintenance in Yokohama, Kanagawa Prefecture, has begun preparations for full operational deployment. The vessel, capable of launching helicopters, Ospreys, and high-speed boats, can also deploy special forces for reconnaissance and target designation missions deep in enemy territory.
As the United States strengthens its deterrence capabilities, North Korean media reported on April 26th that a new destroyer named Chae Hyon had been launched. Equipped with vertical missile launchers and capable of rapid anti-air missile fire, the Chae Hyon is believed to be designed to prevent hostile bombers and aircraft from approaching North Korea.
