Customers (Kunden)
The Indian air force and navy need to replace their Kiran trainers. A requirement of around 210 was mentioned in early 2001, including 24 for the navy.

Remarks (Bemerkungen)
The HJT-36 is designed as a light jet trainer (intermediate jet trainer, IJT, in Indian nomenclature) to replace the HJT-16 Kiran. It features a conventional layout with light alloy construction and use of some composites. Smiths Industries is contributing an integrated avionics system.

History (Geschichte)
Design of the new trainer started in 1997. The HJT-36 was first revealed at the Singapore Air Show in February 1998.
A full-scale mock-up was shown at Aero India in December 1998.
The Indian government awarded a 1,8 billion roupies (42 million Dollar) development contract in July 1999. Design was fully on computers, with 140 CAD/CAM-stations networked to speed progress.
Parts production began in early 2000. In that year, the Larzac engine was selected as well. In June 2001 Smiths Aerospace signed a contract for the development of an integrated avionics system.
Ground tests were under way in February 2003. The first flight of the HJT-36 took place on 7 March 2003 at Bangalore, some six months late. Sqn Ldr Baldev Singh was at the controls for the 20 min hop. The first prototoype is destined for aerodynamic tests.
A second HJT-36 is due to fly in August 2003, fully equipped with a glass cockpit and avionics.
Deliveries could begin in 2005.
