India's Light Combat Helicopter (LCH) is eyeing weapon-based trials with its fourth technology demonstrator, TD-4. The weapon firing trials are planned for the middle of 2016. HAL claims that the LCH is designed to carry out dedicated combat roles such as Air Defence, anti-tank, scout and support combat search/rescue missions. It incorporates a number of stealth features such as reduced visual, aural, radar and infra-red signatures, crashworthy landing gear and armour protection for better survivability. The helicopter is powered by two Shakti engines. There are plans to produce LCH in large numbers to meet the operational requirements.
