Hindustan Aeronautics Limited (HAL) manufactures its aircraft, helicopters, engines and avionics through a network of specialised divisions and complexes spread across several Indian states, rather than from a single plant. This dispersed structure lets HAL run parallel production lines, work closely with regional supplier bases, and support maintenance, repair and overhaul (MRO) work near operating air bases.

Key facts

  • HAL operates roughly 20 manufacturing and production divisions alongside 11 dedicated research and development centres across India
  • Its principal manufacturing locations include Bengaluru, Nashik, Koraput, Lucknow, Hyderabad, Kanpur and Korwa
  • The Nashik complex has licence-built the Su-30MKI fighter since 2004, delivering 222 aircraft to the Indian Air Force
  • The Koraput division manufactures aero engines, including licence-built engines that power the Su-30MKI and Jaguar fleets
  • The Korwa division, near Amethi in Uttar Pradesh, produces avionics and mission systems for HAL's combat aircraft
  • Hyderabad houses avionics and aerospace (composite-structures) divisions supporting multiple aircraft and helicopter programmes

Bengaluru complex

HAL's headquarters and largest manufacturing complex sits in Bengaluru, Karnataka, the company's original home since 1940. The Bengaluru complex houses multiple divisions covering aircraft and helicopter final assembly, overhaul, and engine work, and is where landmark indigenous programmes such as the Tejas light combat aircraft, the HF-24 Marut and the ALH Dhruv family were designed and assembled. It also hosts several of HAL's design and research centres, which work alongside the Aeronautical Development Agency and other defence research bodies, as well as dedicated foundry, forge and composite facilities that feed components to HAL's other divisions across the country.

Nashik and Koraput

HAL's Nashik division in Maharashtra, commissioned in the 1960s, became the home of licence-built Sukhoi Su-30MKI production from 2004, alongside an aircraft overhaul division that services IAF fighter fleets. The Koraput complex in Odisha specialises in aero-engine manufacture, historically producing licence-built Soviet, British and French engines for the MiG, Jaguar and Su-30MKI fleets, and continues to support Sukhoi engine overhaul and manufacture today. Together, these two complexes have underpinned HAL's largest single production programme, the Su-30MKI, from airframe assembly through to engine supply.

Lucknow, Kanpur, Hyderabad and Korwa

The Lucknow accessories divisions manufacture undercarriages and hydraulic and fuel-system components used across HAL's aircraft and helicopter lines, while the Kanpur transport aircraft division builds and maintains fixed-wing transport types such as the Dornier Do-228 for military and paramilitary customers. Hyderabad's avionics and aerospace divisions produce composite structures and mission electronics for several aircraft and helicopter types, and the Korwa avionics division in Uttar Pradesh, near Amethi, manufactures radar and mission-computer systems that feed into HAL's fighter and helicopter programmes elsewhere in the country. Each of these divisions specialises in a distinct stage of the aerospace supply chain, reducing HAL's reliance on any single site or imported sub-system.

Why the network matters

Spreading production across seven or more states gives HAL resilience against disruption at any one site, brings final assembly and overhaul work closer to the air bases and naval yards it serves, and allows the company to build deep, specialised expertise in areas such as engines, avionics and composites rather than concentrating all disciplines in one location. This structure has also supported regional industrial development, with private-sector suppliers clustering around HAL's complexes in Karnataka, Maharashtra, Odisha and Uttar Pradesh.

Collectively, this network of complexes allows HAL to manage the full life cycle of Indian military aircraft, from design and licence production through to overhaul and upgrade, while distributing industrial activity, employment and technical expertise across multiple states.
