The HAL (Hindustan Aeronautics Ltd) HPT-32 "Deepak" ("Lamp") was an Indian basic/primary trainer aircraft development of the Cold War period, the design being adopted by both the Indian Air Force (IAF) and Indian Navy (8 examples) services for basic airman training. Development took place in the 1970s and a first-flight was recorded on January 6th, 1977. Two primary operational versions were eventually produced - the "HPT-32" and "HTT-34".

The aircraft was of fundamental design driven by a two-bladed propeller unit at the nose, seating its crew of two (student and instructor) in side-by-side arrangement, and sporting low-mounted, straight mainplane wing members. The tail unit was largely conventional, given a single vertical fin and low-set horizontal planes. The tricycle undercarriage (nose leg with main legs) were fixed in flight non-retractable) while the wide-view canopy provided excellent vision "out-of-the-cockpit".

As built, the HPT-32 had an overall length of 25.3 feet, a wingspan of 31.1 feet, and a height of 9.6 feet. Empty weight reached 2,280lb with a Maximum Take-Off Weight (MTOW) nearing 2,915lb. The aircraft held a maximum speed of 175 miles-per-hour and ranged out to 755 nautical miles on internal fuel. Four external hardpoints were integral, these positions satisfying armed training endeavors. Up to 562lb of ordnance could be carried including machine gun pods, rockets, and conventional drop bombs.

The base operating version was the HPT-32 and this was followed into service by the HTT-34 which upgraded to a turboprop engine installation offering more power and better performance over the original. The powerplant-of-choice for this entry became the American Allison 250-B17D engine of 420 horsepower and a first-flight of this variant was recorded on June 17th, 1984.

Beyond its basic training role, the versatile, lightweight HPT-32 covered liaison/observation and target towing duties.

The line was replaced by the much more modern Swiss-originated Pilatus PC-7 (Mk.II) in same role during 2013.©MilitaryFactory.com
