Darwin became the centre of international military cooperation on 3 August 2026 as the Japan Air Self-Defense Force (JASDF) deployed its F-35A Lightning II fighter aircraft to RAAF Base Darwin for Exercise Pitch Black 2026. This marks the first time Japanese F-35A stealth fighters have participated in the multinational exercise, representing a significant milestone in defence cooperation between Australia, Japan and other partner nations.

Exercise Pitch Black is one of the world's largest multinational air combat training exercises and is hosted by the Royal Australian Air Force. The 2026 edition has brought together air forces from numerous countries to conduct realistic training scenarios designed to improve interoperability, tactical coordination and regional security cooperation.

The arrival of the Japanese aircraft has attracted attention from defence experts because the F-35A is one of the world's most advanced fifth-generation fighter jets. The deployment allows Japanese pilots to train alongside Australian and allied forces in complex air combat missions while strengthening strategic partnerships across the Indo-Pacific region.

Operations are being conducted from RAAF Base Darwin, one of Australia's most important northern defence bases. During the exercise, aircraft participate in day and night flying missions that simulate a wide range of operational scenarios, including air defence, strike missions and coalition operations. The training helps participating nations improve readiness while sharing operational knowledge and experience.

The exercise also delivers economic benefits to Darwin, with hundreds of military personnel, support crews and international visitors staying in the city throughout the training period. Hotels, restaurants, transport providers and local businesses typically experience increased activity during Exercise Pitch Black.

Residents may notice increased aircraft movements and military activity around Darwin during the exercise. Defence authorities have published scheduled flying times and continue working with the community to minimise disruption while ensuring the success of the international training program.

Exercise Pitch Black has grown into one of Australia's flagship defence activities and demonstrates Darwin's strategic importance in the Indo-Pacific. The participation of Japan's F-35A fleet highlights the expanding defence relationship between the two countries and their commitment to regional stability.
