The proposal is charted out as one of Lockheed's long-term proposals for India, though the company confirms that "[HAL] requires large quantities of Anti-Tank Guided Missile (ATGM) systems to be installed on its Advanced Light Helicopter (ALH) for the Indian Army requirement.
This opportunity is being developed in consultation with the USG and GOI."The Indian Nag anti-tank guided missile (ATGM) has been cleared for production for the Indian Army in the ground-launched variant, though the Helina (HELIcopter-launched NAg) will take atleast another 18 months to be ready for operations and integration on the Dhruv-WSI.
The Helina, incidentally, has similar stated range and other parameters to the Longbow Hellfire. The missile is expected to enter its live test phase this November.
The Army has 104 Dhruv choppers on order from HAL at the moment.
