History

Workers check new fuel tanks during World War II

HAL was established as Hindustan Aircraft Limited in Bangalore on 23 December 1940 by Walchand Hirachand in association with Krishna Raja Wadiyar IV of Kingdom of Mysore.^[10] Walchand Hirachand became chairman of the company. The company's office was opened at a bungalow called "Eventide" on Domlur Road.

The organisation and equipment for the factory at Bangalore was set up by William D. Pawley of the Intercontinental Aircraft Corporation of New York. Pawley obtained a large number of machine-tools and equipment from the United States.

The Mysore Kingdom bought a one-third stake in the company until April 1941 by investing ₹25 lakh as it believed this to be a strategic imperative. The decision by the government was primarily motivated to boost British military supplies in Asia to counter the increasing threat posed by Imperial Japan during Second World War. The Kingdom of Mysore supplied two directors, Air Marshal John Higgins was resident director. The first aircraft built was a Harlow PC-5.^[11] On 2 April 1942, the government announced that the company had been nationalised when it bought out the stakes of Seth Walchand Hirachand and other promoters so that it could act freely. The Mysore Kingdom refused to sell its stake in the company but yielded the management control over to the British Indian Government.

In 1943 the Bangalore factory was handed over to the United States Army Air Forces but still using Hindustan Aircraft management. The factory expanded rapidly and became the centre for major overhaul and repair of American aircraft and was known as the 84th Air Depot. The first aircraft to be overhauled was a Consolidated PBY Catalina followed by every type of aircraft operated in India and Burma. When returned to Indian control two years later the factory had become one of the largest overhaul and repair organisations in the East. In the post war reorganisation the company built railway carriages as an interim activity.

After India gained independence in 1947, the management of the company was passed over to the Government of India.

The total number of broad-gauge coaches manufactured by the Hindustan Aircraft Limited during the year 1954 is 158. ^[12]

Hindustan Aeronautics Limited (HAL) was formed on 1 October 1964 (the Registrar of Companies has a registration date of 16 August 1963)^[13] when Hindustan Aircraft Limited joined the consortium formed in June by the IAF Aircraft Manufacturing Depot, Kanpur (at the time manufacturing HS748 under licence) and the group recently set up to manufacture MiG-21 under licence, with its new factories planned in Koraput, Nasik and Hyderabad.^[14] Though HAL was not used actively for developing newer models of fighter jets, except for the HF-24 Marut, the company has played a crucial role in modernisation of the Indian Air Force. In 1957, the company started manufacturing Bristol Siddeley Orpheus jet engines under licence at new factory located in Bangalore.

Production line of the HAL Dhruv at Bangalore

During the 1980s, HAL's operations saw a rapid increase which resulted in the development of new indigenous aircraft such as the HAL Tejas and HAL Dhruv. HAL also developed an advanced version of the Mikoyan-Gurevich MiG-21, known as MiG-21 Bison, which increased its life-span by more than 20 years. HAL has also obtained several multimillion-dollar contracts from leading international aerospace firms such as Airbus, Boeing and Honeywell to manufacture aircraft spare parts and engines.

By 2012, HAL was reportedly bogged down in the details of production and has been slipping on its schedules.^[15] On 1 April 2015, HAL reconstituted its Board with TS Raju as CMD, S Subrahmanyan as Director (Operations), VM Chamola as Director (HR), CA Ramana Rao as Director (Finance) and D K Venkatesh as Director (Engineering & R&D). There are two government nominees in the board and six independent directors.

Light Combat Helicopter induction into the Indian Army

In March 2017, HAL's chairman and managing director T Suvarna Raju announced that the company had finalised plans for an indigenisation drive. The company plans to produce nearly 1, 000 military helicopters, including Kamov 226, LCH (Light Combat Helicopter) ALH (Advanced Light Helicopter), and over 100 planes over the next 10 years. HAL will manufacture the Kamov 226T helicopter under a joint venture agreement with Russian defence manufacturers. The Kamov 226T will replace the country's fleet of Cheetah and Chetak helicopters. Over the next 5 years, HAL will carry out major upgrades of almost the entire fighter fleet of the Indian Air Force, including Su-30MKI, Jaguars, Mirage and Hawk jets, to make them "more lethal". The company will also deliver 123 Tejas Light Combat Aircraft to the IAF from 2018 to 2019, at a rate of 16 jets per year.^[16] LCH production will now take place in a newly built Light Combat Helicopter Production Hangar at Helicopter Division in HAL Complex.^[17]

In view of Make in India policy and to increase the share of defence exports to achieve the target of $5 billion by 2025, HAL is planning to set up logistic bases in Indonesia, Malaysia, Sri Lanka and Vietnam with priority target for Southeast Asia, West Asia and North African markets. It would not only help to promote HAL products but also act as service centre for Soviet/Russian origin equipment.^[18]

In October 2024, HAL was given Maharatna status, which allows the company to have more operational and financial autonomy.^[19]

Operations

One of the largest aerospace companies in Asia, HAL has annual turnover of over US$3 billion. More than 40% of HAL's revenues come from international deals to manufacture aircraft engines, spare parts, and other aircraft materials. A partial list of major operations undertaken by HAL includes the following:
