LCH, a derivative of the Advanced Light Helicopter (Dhruv), is an attack helicopter and the first of its kind in the country. The LCH inherits many technical features of the Dhruv which includes the rotor system Transmission, power plant, Hydraulics, IADS, weapons system and avionics.

The features that are unique to LCH are sleek and narrow fuselage, tri-cycle crashworthy landing gear, tandem cockpits, crashworthy and self sealing fuel tanks, aero foil shaped stub wings for weapons, armour protection, NBC protection and, low visibility features which make the LCH lethal, agile and survivable. LCH prototype development was based on the concept of design, ground testing and fabrication concurrently.

This resulted in building the first machine within 40 months. The design and manufacturing was carried-out using the state-of-art CAD/CAM facilities which obviated the requirement of an interface check rig. The ground testing included wind-tunnel testing, landing gear drop tests, and shake test. A mock up was also built for evaluation by the Indian Air Force.
The development team included members of HAL, Indian Air Force, the certification authorities CEMILAC, DGAQA and the various suppliers of the onboard systems.
