Bengaluru: Hindustan Aeronautics Limited (HAL) is set to deliver the first batch of HTT-40 basic trainer aircraft to the Indian Air Force (IAF), strengthening indigenous pilot training capabilities and helping meet the force’s growing requirement for new pilots.
Three HTT-40 (Hindustan Turbo Trainer-40) aircraft are ready for delivery, with two manufactured at HAL’s Bengaluru facility and one at its Nashik facility, according to officials aware of the development.
The deliveries mark an important step in the long-delayed HTT-40 programme, which is aimed at providing the IAF with an indigenous platform for basic flying training.
Three HTT-40 Aircraft Ready for IAF Delivery
HAL has completed three HTT-40 aircraft for the first batch of deliveries:
- Two aircraft have been built at HAL’s Bengaluru facility.
- One aircraft has been manufactured at the Nashik facility.
- The three aircraft are now ready to be handed over to the IAF.
- The HTT-40 is designed for basic flying training of rookie pilots.
The induction is expected to strengthen the IAF’s basic training fleet while reducing dependence on imported trainer aircraft.

IAF Ordered 70 HTT-40 Aircraft for ₹6,838 Crore
The IAF had placed an order for 70 HTT-40 basic trainer aircraft worth ₹6,838 crore around three years ago.
Under the contract, HAL was scheduled to deliver 12 aircraft during fiscal year 2025-26. However, the company could not deliver any aircraft during the period due to delays in the supply of engines.
The programme faced a major bottleneck because of shortages of the TPE331-12B turboprop engines required for the aircraft.
Honeywell Engine Supplies Help Restart Deliveries
US-based Honeywell had signed a $100 million contract for the supply and manufacture of 88 TPE331-12B engines and kits for the HTT-40 programme.
Under the arrangement:
- Honeywell will directly supply 16 engines.
- HAL will manufacture the remaining engines through technology transfer.
- The first engine was originally scheduled for delivery in September 2025.
- Supply-chain bottlenecks delayed the engine deliveries.
- Honeywell delivered the first batch of engines a few months ago and has assured HAL of timely supplies going forward.
The availability of engines has allowed HAL to resume the planned production and delivery of HTT-40 aircraft.
HAL Can Produce 20 HTT-40 Aircraft Annually
HAL has now expanded its HTT-40 manufacturing capability across its Bengaluru and Nashik facilities.
The company can currently produce up to 20 HTT-40 aircraft annually from the two facilities.
The production lines for the HTT-40 and LCA-Mk1A were inaugurated at HAL’s Nashik facility by Defence Minister Rajnath Singh last October as part of efforts to expand indigenous aircraft manufacturing capacity.
The increased production capacity is expected to help HAL accelerate deliveries and meet the IAF’s contracted requirement.
HTT-40 to Strengthen IAF’s Basic Pilot Training
The HTT-40 is intended to conduct the initial flying training of IAF pilots before they move on to more advanced aircraft.
At present, rookie pilots undergo Stage-I (ab initio) flying training on the Swiss-origin Pilatus PC-7 MkII basic trainer aircraft.
After completing the common initial training stage, pilots are divided into three streams:
- Fighter
- Transport
- Helicopter
Pilots selected for the fighter stream subsequently continue training on the PC-7 MkII and Kiran Mk-1A jet trainers before progressing to the Hawk advanced jet trainer for Stage-III training.
The induction of the HTT-40 will provide the IAF with an indigenous option for basic pilot training.
HTT-40 Induction Marks Key Step for Indigenous Aerospace Manufacturing
The first deliveries are significant for HAL as it seeks to scale up production and overcome delays in the programme.
The aircraft will add to India’s indigenous defence manufacturing capabilities and support the IAF’s long-term pilot training requirements.
With production now underway at both Bengaluru and Nashik and engine supplies expected to become more regular, HAL is positioned to increase the pace of HTT-40 deliveries in the coming years.
