Passage: The HAL Rudra, earlier known as Dhruv-WSI (Weapons Systems Integrated), is an attack variant designed for the Indian Army. Development was sanctioned in December 1998 and the prototype first flew on 16 August 2007; it is to be armed with both anti-tank and anti-aircraft missiles, and a 20-mm turret-mounted cannon. The Dhruv-WSI is to be capable of conducting combat air support (CAS) and anti-submarine warfare (ASW) roles as well. In addition to the Dhruv-WSI, HAL is also developing the Light Combat Helicopter (LCH) based on the Dhruv for the Indian Armed Forces. It is fitted with stub wings for carrying up to eight anti-armour missiles, four air-to-air missiles, or four pods loaded with either 70 mm or 68 mm rockets. The LCH will also have FLIR (Forward Looking Infrared), a CCD (Charge Coupled Device) camera, and a target acquisition system with laser rangefinder and thermal vision.
