F-22 Tsuiki deployment operations began at Japan’s Tsuiki Air Base on Oct. 19, 2026, as U.S. Air Force Raptors arrived for Exercise Keen Sword 27. Officially released Air Force photographs identify the jets as belonging to the 525th Expeditionary Fighter Squadron, deployed from Joint Base Elmendorf-Richardson, Alaska.
The move puts a U.S. fifth-generation fighter contingent at a Japanese base on Kyushu for a bilateral exercise with multinational participation. The U.S. military describes the training as intended to improve readiness and coordination with Japan’s Self-Defense Forces.
Although the images were released several days after the aircraft arrived, the reported event date is Oct. 19. The deployment is part of a scheduled exercise, not evidence of combat sorties or a permanent reassignment of the squadron.

F-22 Tsuiki Deployment Uses a Japanese Air Base
The Air Force photography released Oct. 22 depicts maintenance personnel and at least one F-22 at Tsuiki. The accompanying captions identify the 525th Expeditionary Fighter Squadron and its Alaska home base, supplying primary confirmation of the deployment location and aircraft type.
Tsuiki is a Japan Air Self-Defense Force installation in Fukuoka Prefecture. Operating there during Keen Sword provides an opportunity for combined procedures at a Japanese-operated facility rather than relying solely on a permanent U.S. base.
Publicly available images establish aircraft presence, but do not establish the number of sorties flown, weapons loaded or operational tactics practiced. Those details should not be inferred from a photo showing an aircraft and ground crew.
Keen Sword 27 Covers More Than Fighter Operations
Keen Sword 27 is the latest iteration of the recurring Japan–U.S. field exercise. Public reports put the overall training period between Oct. 19 and Oct. 29, with land, maritime, air and logistics activities conducted at locations across Japan.
The exercise includes participants from several partner countries. The operations described in the current reporting range from air and missile defense to resupply and coordination of combined forces, rather than a single air-combat event at Tsuiki.
USNI News reported that aircraft supporting the exercise also include tanker and transport platforms. Such support aircraft allow participating forces to rehearse coordination across different mission types, although their presence does not disclose particular flight plans or deployment intentions.
What the Raptor Presence Means for Training
The F-22 is a U.S. Air Force air-superiority fighter. Its use in a multinational exercise gives participating forces opportunities to coordinate around a fifth-generation platform and practice procedures for working together in a shared operating environment.
Those are the stated exercise goals; they should not be described as confirmation of a planned combat mission or as a response to a specific immediate incident. Regional tensions are part of the broader setting but are not proof of the purpose of any individual training sortie.
TAD has previously reported another allied fifth-generation fighter basing development in Finland. This Japan deployment differs in aircraft, geography and mission, but both show how basing arrangements feature in partner airpower planning.
