The division is supported by the co-located R&D centre – Rotary Wing Research & Design Centre (RWR&DC).
The MRO division caters to the Maintenance, Repair & Overhaul activities of helicopters.  The Rotory Wing Academy focuses on training of pilots.
 
HAL started manufacturing of helicopters in 1962, by entering an agreement with M/s SUD-AVIATION (Presently M/s EUROCOPTER, France) for production of Aloutte III helicopters. (Chetak). The first Chetak (Aloutte III) in ‘Fly Away’ condition delivered in 1965.
 
License agreement for production of Cheetah (LAMA SA 315-B) signed with M/s SNIAS (presently M/s, Eurocopter) in 1970. First
Cheetah manufactured from raw materials was delivered in 1976-77.

In 1990s, HAL has developed a light attack helicopter “Lancer”. The basic structure of the lancer is derived from reliable and proven Cheetah helicopter. The helicopter has bullet proof front panels. Gun cum Rocket pod one each (70 mm Rocket+12.5 mm Gun) fitted on either side. An optical sight has been fitted for accurate firing.
 
The Cheetal helicopter is a re-engined variant of Cheetah helicopter. The Cheetal helicopter set the world record of world’s highest landing at ‘Saser Kangri’ of Himalayas in 2006.HAL Helicopter division has successfully manufactured 682 Single Engine helicopters.
 
HAL achieved self-reliance in design, developing & manufacturing of twin engine Advanced Light Helicopter (ALH).  ALH is a multi-role, multi mission all weather helicopter in the 5.5 ton category. The indigenously designed twin engine helicopter started series production during 2001-2002. Division has produced 336 ALH in different variants.

LCH is indigenously designed and developed as a Dedicated Combat Helicopter in 5.8 Ton category. Dedicated combat helicopter capable of operating in all-weather & extreme climatic conditions with high degree of reliability, high agility and maneuverability. The LCH is being designed to fit into an anti-infantry and anti-armour role and will be able to operate at high altitudes. LCH is an attack helicopter with tandem seat configuration. Division has produced 10 LCH against the limited series production of LCH.

Light Utility Helicopter (LUH) is a single engine 3 ton Helicopter indigenously designed and developed by HAL to meet the requirements of Indian Armed Forces. This helicopter is basically for utility role, observation /reconnaissance role etc. Further in a developing economy like India, helicopters of this category are of huge demand in Civilian side.
