Astra
The 3.8-metre long Astra is the smallest of the missiles developed by DRDO. It can be launched from different altitudes and cover 110 km when fired from an altitude of 15 km, reach 44 km when launched from an altitude of eight km, and 21 km when launched from the sea-level. Designed to intercept and destroy enemy aircraft at supersonic speeds (1.2 to 1.4 Mach) in head-on and tail-chase modes, the missile uses solid propellant and can carry a conventional warhead weighing 15 kg.
