Joint B-52H USAF patrol escorted by Japan Air Self-Defense Force fighters

As part of the ongoing bilateral military co-operation between the two countries, US Air Force (USAF) B-52H bombers were escorted for the first time this year by Japan Air Self-Defense Force fighters-F-15s and F-2s-during a Pacific patrol. The mission took place in international airspace over the South China Sea and the Sea of Japan, against a backdrop of a sharp rise in Chinese and Russian naval and air activity around several sensitive areas near Japan’s island chains-an enduring source of concern in Tokyo.

Japan’s Ministry of Defence reported that, from 16 to 18 February, Japan Air Self-Defense Force fighter units from the 7th, 8th and 9th Air Wings-based at Hyakuri, Tsuiki and Naha-linked up with USAF B-52H aircraft after the bombers deployed from Andersen Air Force Base on Guam. According to the information released, the aircraft carried out combined sorties and tactical co-ordination activities designed to strengthen interoperability.

Monitoring, co-ordination and the message behind the flights

On 18 February, the exercise was also monitored remotely from the headquarters at Ichigaya and Yokota, where Japanese officials received a detailed briefing on how the operations unfolded. As is customary, Japanese authorities emphasised that drills of this kind are intended to demonstrate the co-operation and resolve shared by both countries in the face of any attempt to alter the regional “status quo” by force.

Even so, deploying B-52H bombers alongside Japanese fighters is not a one-off event. Similar training was recorded during 2025, particularly after combined Russian and Chinese bomber operations were observed near the Japanese archipelago. By way of example, last December the United States and Japan conducted joint manoeuvres involving B-52H and F-15J aircraft in response to long-range air patrols carried out by Moscow and Beijing in the western Pacific.

In the same vein, the use of US strategic bombers in the Asia–Pacific theatre functions as a visible deterrent: it can project power over long distances while integrating with allied forces. It is also worth noting that, from Japan’s perspective, the presence of these platforms reinforces the security umbrella provided by Washington and highlights the strength of their mutual defence relationship.

The operating areas: the South China Sea and the Sea of Japan

The choice of training areas in the Pacific is far from incidental. The South China Sea is a frequent arena for friction between Japan and China, especially in relation to the Senkaku/Diaoyu islands, while the Sea of Japan concentrates a significant share of Russian air and naval activity in the Far East.

Within this setting, the context for the combined manoeuvres with B-52H bombers enabled several aims to be met-ranging from tighter operational co-ordination in the event of a future conflict to sending a clear political signal in an environment where the military activity of regional actors continues to increase.

Guam: a strategic island for the US Air Force

As noted earlier, the USAF’s B-52H strategic bombers departed from Guam, a strategically important Indo-Pacific location for the United States. The island forms part of Bomber Task Force (BTF) operations and represents the closest US territory to the region-defined by its proximity to Japan, South Korea and the Philippines, among others-while serving above all as a deterrence hub focused on China.

Its position gives aircraft-especially bombers-the ability to operate quickly towards the South China Sea, the Korean Peninsula, or even the Taiwan Strait. It also provides the United States with a staging point for combined flights with Japan, South Korea, Australia and the Philippines, underscoring cohesion with these partners.

Lastly, Andersen Air Force Base’s location allows the United States to sustain operations without relying solely on allied bases, such as those in Japan and South Korea, and it also serves as an instrument of indirect pressure within the regional landscape.
