Indian Air Force is entering a critical transition phase in its strategic airlift capability, increasingly relying on its aging fleet of Ilyushin Il-76 to bridge a capability gap until next-generation transport platforms are introduced. With production of the Boeing C-17 Globemaster III discontinued and India’s Medium Transport Aircraft still under development, the Il-76 has become a key interim solution expected to remain in service into the next decade.
Inducted in the late 1980s, the Il-76 has long served as the backbone of India’s heavy-lift capability. However, the fleet has declined from its original 17 aircraft to around 11–12 operational units. Maintenance challenges—particularly limited access to spare parts and engine support—have affected availability, with at least two aircraft grounded at Chandigarh since 2022 due to issues with Soloviev D-30KP engines. These supply constraints worsened following the Russo-Ukrainian War, which disrupted access to Russian-origin components.
To sustain operations, the IAF has resorted to cannibalizing parts from grounded aircraft—a short-term solution that underscores the logistical strain of maintaining legacy platforms. In response, the force has begun engaging domestic private firms for structural repairs and undercarriage maintenance, marking a shift away from reliance on Russian OEM support.
Despite its age, the Il-76 remains indispensable for strategic air mobility, enabling rapid deployment of troops, heavy equipment, and humanitarian aid. To maintain this capability, the IAF is pursuing a comprehensive life-extension and modernization plan aimed at keeping at least 10 aircraft operational until the mid-2040s.
Key upgrade proposals include replacing the older D-30KP engines with Aviadvigatel PS-90A-76 units, offering improved thrust, fuel efficiency, and compliance with global emission standards. Additional plans involve transitioning to a glass cockpit with digital avionics, integrated flight management systems, and enhanced navigation capabilities.
The upgrades may also incorporate indigenous communication systems and network-centric features to improve integration with modern command-and-control architectures. Parallel efforts are exploring structural enhancements to extend the aircraft’s total technical life beyond its current limit of around 2035, potentially pushing operational viability closer to 2050.
