The LCH, a twin-engine helicopter in the 5.8-tonne class, has advanced technologies and stealth features for effective combat roles. The chopper is designed to carry out multiple roles such as destruction of enemy air defence, counter-insurgency, search and rescue and anti-tank operations etc. ''The LCH is the only attack helicopter in the world which can land and take-off at an altitude of 5,000 m (16,400 ft) with a considerable load of weapons and fuel, according to the defence ministry.
Post-1999 Kargil war, the need to have an effective combat helicopter to deliver precision strikes at high altitudes was felt by the IAF. The design and development of LCH were sanctioned by the government in October 2006. Subsequently, the Indian Army joined the programme in December 2013 leading to a total projected requirement of 160 LCHs.
The prime minister also handed over drones, designed and developed by Indian startups, to the Indian Army.
The Indian Army has decided to procure these drones after detailed testing and trials. The electronic warfare systems were designed by the DRDO and manufactured by Bharat Electronics Limited (BEL). They have been manufactured for naval ships including that for Indian Aircraft Carrier Vikrant. Officials said the advanced EW suite will be used in different naval ships including destroyers and frigates.
