Hindustan Aeronautics Limited (HAL) has delivered the first three HTT-40 basic trainer aircraft to the Indian Air Force (IAF), opening the induction of an indigenous platform meant to strengthen Stage-I flying training. The service expects the transition to full rookie pilot training on the new aircraft to take up to two years, as more trainers arrive and instructors are prepared for the type.
The handover took place in Bengaluru on 18 September 2026 during a ceremony attended by Defence Minister Rajnath Singh. In IAF service, the HTT-40 has been named “Ankur”. The first three aircraft will be based at the Flying Instructors’ School in Tambaram, near Chennai.
At this initial stage, the aircraft will be used to familiarise instructors with its handling and systems, frame standard operating procedures, develop the training syllabus and set proficiency standards for future trainee pilots. The IAF intends to start routine ab-initio training only after it has built up a fleet of about 25–30 aircraft and has enough qualified instructors in place. The eventual main base for Stage-I training is expected to be the Air Force Academy near Hyderabad.
Order, production and supply chain
The IAF has ordered 70 HTT-40 aircraft under a contract valued at approximately ₹6,828–6,838 crore. The agreement was signed around 2023, following earlier steps at DefExpo 2022 and Cabinet approval in March 2023. The package includes associated equipment and training aids, including simulators.
Delivery of the aircraft had been delayed mainly because of supply-chain issues linked to the Honeywell TPE331-12B turboprop engines. Under a related arrangement, Honeywell is supplying 88 engines and kits, with an initial batch delivered directly and the remaining units to be manufactured by HAL under technology transfer. With engine supply stabilising, HAL expects to produce up to 20 HTT-40 aircraft annually from its Bengaluru and Nashik facilities.
The aircraft currently has about 56% indigenous content. HAL plans to increase that figure to above 60% through further indigenisation of components and subsystems.
What the HTT-40 is designed to do
The HTT-40 has been designed by HAL’s Aircraft Research and Design Centre as a fully aerobatic, tandem-seat turboprop trainer. It features an air-conditioned cockpit, modern glass cockpit avionics, hot-refuelling capability and zero-zero ejection seats.
According to the source details, the aircraft has a maximum speed of around 450 km/h, a range of approximately 1,000 km, a service ceiling of 6,000 metres and an endurance of about three hours. It is cleared for load factors of +6/-3g. The type is intended for basic flying, aerobatics, general handling, instrument flying, navigation, night flying and close formation flying.
The HTT-40 first flew on 31 May 2016 and later underwent extensive development and certification trials.
Why the induction matters
The arrival of the HTT-40 restores an indigenous option in the basic trainer segment. The IAF had grounded its earlier HAL-built HPT-32 Deepak fleet in 2009 after a series of fatal crashes. Since then, Stage-I training for rookie pilots has been carried out mainly on the Swiss-origin Pilatus PC-7 MkII aircraft, of which 75 were acquired.
After Stage-I, pilots move into fighter, transport or helicopter streams and continue training on aircraft such as the Kiran, Hawk, or the relevant transport and helicopter platforms before operational conversion. The HTT-40 is expected to complement, rather than immediately replace, the PC-7 fleet while helping address the IAF’s broader shortage of basic trainers, estimated at around 180 aircraft.
The first three deliveries mark only the opening phase of the larger induction plan, but they also begin a measured transition toward indigenous basic training capability. For now, the IAF is focusing on instructor familiarisation, syllabus development and fleet build-up before the HTT-40 enters regular use for trainee pilots.
