Astra, developed by DRDO, belongs to which class of missiles?
- A.Surface to surface
- B.Air to air
- C.Surface to air
- D.Anti-tank
Correct answer
Explanation
The correct answer is B, air to air. Astra is a beyond visual range air-to-air missile, which means it is fired from a fighter aircraft at an enemy aircraft the pilot cannot see with the eye, using radar to find and follow the target. It is carried on Indian Air Force fighters and was developed to replace imported missiles of the same class, giving India a weapon it can make and improve at home.
Option A, surface to surface, covers Prithvi, Agni and Shaurya, which are fired from the ground at ground targets. Option C, surface to air, covers Akash, Trishul and QRSAM, which are fired from the ground at aircraft, so the direction is the reverse of Astra. Option D, anti-tank, is the class of Nag and HELINA. Keeping the first word as the launch place and the second as the target makes these questions easy.
