In a significant development for global military aviation, Japan has reportedly approached the United States Air Force (USAF) to explore the acquisition of Boeing’s C-17 Globemaster III strategic airlifters. This move comes on the heels of India’s renewed interest in procuring additional C-17s to bolster its airlift capabilities, signaling a broader trend among nations seeking reliable, high-capacity transport aircraft.
However, with Boeing having ceased C-17 production nearly a decade ago in 2015, both countries face challenges in securing these coveted platforms. Japan’s interest is particularly intriguing given its domestically developed Kawasaki C-2 transport aircraft, raising questions about the motivations behind its pursuit of the C-17.
Japan, which currently does not operate any C-17s in its Japan Air Self-Defense Force (JASDF) fleet, has traditionally relied on a mix of transport aircraft, including the Lockheed Martin C-130 Hercules and the indigenously developed Kawasaki C-2. The C-2, a mid-size, twin-turbofan military transport aircraft, was designed to meet Japan’s specific airlift requirements. Boasting a range of approximately 7,600 km (with a 20-ton payload), high speed, and advanced avionics, the C-2 is a capable platform for regional missions, humanitarian assistance, and disaster relief operations—key priorities for Japan given its geographic and geopolitical context.
However, the C-17 Globemaster III offers distinct advantages that may explain Japan’s interest. With a maximum payload capacity of 77.5 tons (compared to the C-2’s 37.6 tons), a longer range of 8,700 km (with a 40-ton payload), and proven interoperability with U.S. and allied forces, the C-17 is a true strategic airlifter designed for rapid global deployment. Its ability to operate from short, austere runways and carry oversized cargo, such as main battle tanks or helicopters, makes it uniquely suited for expeditionary operations and large-scale disaster response.
Analysts speculate that Japan’s pursuit of the C-17 could be driven by evolving security dynamics in the Indo-Pacific region. With increasing tensions involving China and North Korea, Japan may seek to enhance its strategic airlift capacity to support rapid troop deployments, evacuate citizens from conflict zones, or deliver aid during crises. Additionally, the C-17’s compatibility with U.S. forces could strengthen Japan’s role in joint operations under the U.S.-Japan security alliance, particularly in scenarios requiring heavy-lift capabilities beyond the C-2’s scope.
Yet, the question remains: why pursue the C-17 when Japan has invested heavily in the C-2? The C-2, while advanced, is still a relatively new platform with a smaller production run, and its operational costs and scalability may not match the C-17’s proven track record. The C-2 also lacks the global operational pedigree of the C-17, which has been battle-tested in conflicts and humanitarian missions worldwide. Japan may view the C-17 as a complementary asset to address capability gaps, particularly for long-range, heavy-lift missions that the C-2 cannot fully support.
India, one of the largest operators of the C-17 with a fleet of 11 aircraft, has also expressed interest in acquiring an additional three to four units. The Indian Air Force (IAF) has been highly satisfied with the C-17’s performance, citing its high availability rate—often exceeding 85%—and versatility in supporting missions ranging from military logistics to disaster relief. The IAF’s C-17s have been instrumental in operations such as troop deployments along the Line of Actual Control (LAC) with China, humanitarian aid deliveries, and strategic airlifts to remote airfields in the Himalayas.
The IAF’s desire for more C-17s is partly driven by the poor availability of its aging Ilyushin Il-76 fleet, which has faced maintenance challenges and obsolescence issues. The Il-76, while capable, lacks the C-17’s payload capacity (77.5 tons vs. 48 tons) and modern avionics, making it less efficient for India’s growing airlift demands. With India’s strategic focus on enhancing its military posture in the Indo-Pacific and supporting rapid-response capabilities, the C-17 remains a critical asset.
The biggest hurdle for both Japan and India is that Boeing halted C-17 production in 2015 after delivering 279 aircraft to operators worldwide, including the USAF, India, Australia, Canada, Qatar, the UAE, Kuwait, and the UK. With no new C-17s being built, any acquisitions would likely involve refurbished or surplus aircraft from the USAF’s inventory, subject to approval under the U.S. Foreign Military Sales (FMS) program.
For Japan, securing C-17s could also involve navigating domestic political and industrial considerations. The Kawasaki C-2 program represents a significant investment in Japan’s aerospace industry, and diverting resources to foreign-built aircraft might face resistance from stakeholders advocating for indigenous platforms. However, the C-17’s unmatched capabilities may outweigh such concerns, particularly if Japan prioritizes operational readiness over industrial priorities.
India, already an experienced C-17 operator, may have an easier path to acquiring additional units, but availability remains a constraint. The USAF maintains a fleet of over 200 C-17s, but transferring even a small number would require careful consideration of its own operational needs. Alternatively, India could explore purchasing aircraft from allied operators, though this would involve complex negotiations and potential refurbishment costs.
