Hey!! The DRDO Anti-tank missile (ATM) is a first generation wire-guided missile developed in India by Defence Research and Development Laboratory (DRDL) of Defence Research and Development Organisation (DRDO).

The missile was test-fired near Imarat, a village on the outskirts of Hyderabad, which held the reliability order of 65%.

The test trials were attended by Gen Bewoor, then Deputy Chief of Army Staff of the Indian Army

Two Indian army teams which were trained on European ATMs, Cobra and ENTAC, carried out the tests.

The missile was tested 16 times and hit its target 14 times.

Control and Guidance

The actuator and gyroscope were the main components of the control and guidance system of the ATM.

The Actuators were spoiler type, (similar to Mosquito (missile)), which gave a response time of 10 millisecond with a stay time varying from 80-20 and 20-80 milliseconds.

The gyroscope developed for the ATM was a three degree freedom gyroscope


Development

After the first aerodynamic design was completed, a full-scale model of the complete configuration was tested in a wind tunnel at IISc Bangalore.
