Japanese F-35A stealth fighters are participating in training missions over Australia for the first time as part of Exercise Pitch Black, a biennial multinational air combat exercise running from July 20 to August 7. This deployment marks a significant step in defense cooperation among Japan, Australia, and the United States, reflecting a strategic shift aimed at enhancing allied resilience amid increasing tensions with China, particularly concerning Taiwan.
Exercise Pitch Black involves up to 100 aircraft from multiple nations, providing a large-scale training environment. The drill follows closely on the heels of the inaugural Southern Cross exercises, which saw Japanese, Australian, and US F-35s training together. Southern Cross also introduced a new trilateral logistics arrangement that facilitates sharing fuel and equipment among the three air forces. This arrangement is intended to improve the sustainability of coalition air operations far from home bases.
Experts characterize these developments as part of a broader pivot toward using northern Australia as a critical rear-area hub for coalition air operations. The region's remoteness, less congested airspace, and expanded infrastructure—including enhanced fuel storage and upgraded bases—make it strategically valuable for refueling, rearming, and relaunching aircraft while maintaining distance from potential conflict zones near China’s coast. This setup allows coalition forces to maintain operational reach with an increased degree of flexibility and survivability.
Timothy Heath, head of the defense research firm Perceptum, noted that improved interoperability between partners enables forces to relocate and operate more easily from alternate bases, enhancing their survivability. However, Heath cautioned that northern Australia is unlikely to replace forward bases located closer to contested areas such as Japan and the Philippines, which remain central to operations near Taiwan.
Japan’s involvement in these exercises is motivated by a desire to train in large, unconstrained airspace unavailable domestically, while deepening interoperability with allied forces. Masashi Murano, senior fellow at the Hudson Institute, said Tokyo views northern Australia as a complementary asset providing strategic depth and sustainment rather than a frontline operating base. Japan continues to prioritize strengthening a network of defense infrastructure across the Pacific, including in the home islands, the Philippines, and the Mariana Islands.
The growing integration of Japan, Australia, and the United States is further supported by the Reciprocal Access Agreement, which came into effect in 2023. This agreement enables more routine deployments of the Japan Air Self-Defense Force to Australia, strengthening bilateral military ties and complicating potential adversaries’ strategic calculations.
The emphasis on logistics and industrial cooperation is also increasing, reflecting lessons from recent conflicts that demonstrated the rapid depletion of munitions and equipment during sustained operations. Ensuring allied forces can support each other’s supply chains and production capabilities is becoming an essential element of maintaining long-term combat readiness.
