The flight-test was jointly conducted by team of scientists of the Defence Research and Development Organisation (DRDO), the Indian Army, and the Indian Air Force, as part of the user validation trials.
The flight trials were conducted from an Advanced Light Helicopter (ALH) and the missile was fired successfully engaging simulated tank target.
Guided by an Infrared Imaging Seeker (IIR) operating in the Lock on Before Launch mode, the missile is one of the most advanced anti-tank weapons in the world.
In continuation to validation trials conducted at Pokhran, proof of efficacy at high altitudes paves the way for its integration on the ALH.
The trials were witnessed by senior Army commanders and senior scientists of DRDO.
Defence Minister Rajnath Singh congratulated the DRDO and the Indian Army for the maiden achievement through joint work. Defence Research and Development Secretary and DRDO Chairman G. Satheesh Reddy congratulated the teams for the commendable job performed in difficult conditions.
The missile hit both the targets under different ranges and conditions with very high accuracy as desired by the armed forces, an official statement said.
"With these two successful flight trials, and the flight test conducted earlier in June in the peak of summer, the complete functionality of Nag ATGM along with launcher system NAMICA has been established and marked the successful completion of development trials of Nag Missile," the release said.
The test on Wednesday was the third stage of successful testing of the MPATGM, a low-weight fire-and-forget missile.
A Defence Ministry official said all objectives of the test mission conducted on Wednesday were met by the missile.
The missile was launched from a man portable tripod launcher and the target was mimicking a functional tank in the Kurnool ranges. The missile hit the target in top attack mode and destroyed it with precision.
The third-generation missile is incorporated with state-of-the-art infrared imaging seeker along with advanced avionics. The missile weighs around 14 kg and can be used by infantry battalions against armored vehicles. It has a maximum range of around 2.5 kms and will replace Soviet-era anti-tank missiles that are being used by the Army.
Earlier, India had cancelled a mega order of Israeli anti-tank missile, Spike, in favor of the MPATGM. A multi-million dollar deal with an Israeli firm for the Spike missile had been abandoned after the DRDO promised to deliver its indigenously developed guided missile by 2021.
The DRDO successfully developed the anti-tank guided missile without any technological assistance from foreign firms.
The missile systems have been designed and developed by the Defence Research and Development Organisation (DRDO).
Joint user trials for Helina, the Army version, and Dhruvastra, the Air Force version, were carried out from the Advanced Light Helicopter (ALH) platform in the desert ranges.
Five missions were carried out for evaluating the missile capabilities in minimum and maximum ranges, the DRDO said.
The missiles were fired in hover and maximum forward flight against realistic static and moving targets.
"Some missions were carried out with warheads against derelict tanks. A mission was carried out against a moving target from a forward flying helicopter," DRDO said.
The Helina and Dhruvastra are third generation, Lock on Before Launch (LOBL) fire and forget Anti-Tank Guided Missiles that can engage targets both in direct hit mode as well as top attack mode.
One of the most advanced anti-tank operations in the world, the missile system has all-weather day and night capability and can defeat battle tanks with conventional armour as well as with explosive reactive armour. Now, it is ready for induction into the armed forces.
Defence Minister Rajnath Singh congratulated DRDO, the Army and Air Force for the achievements.
