ASTRA: Air to Air missile


The Astra missile programme is headed by the Defence Research & Development Organisation (DRDO). The goal of this programme is to provide the Indian Air Force (IAF) with an indigenously-designed beyond visual range (BVR) air-to-air missile to equip the IAF’s Mirage 2000, MiG-29, Su-30MKI and the future Light Combat Aircraft (LCA).

This indigenous missile is intended to have performance characteristics similar to the R-77RVV-AE (AA-12), which currently forms part of the IAF’s missile armoury.

The missile is 3.8 metres long and is said to be configured like a longer version of the Super 530D, narrower in front of the wings. Astra uses a HTPB solid-fuel propellant and a 15 kg HE (high-explosive) warhead, activated by a proximity fuse. Although designed to use a locally-developed solid fuel propellant, DRDO is also looking at rocket/ramjet propulsion to provide greater range and enhanced kinematic performance.

The missile, which has strike range of 25 to 40 km, uses a terminal active radar-seeker and a mid-course internal guidance system with updates to track targets.

The missile has a maximum speed of Mach 4+ and a maximum altitude of 20 km. The missile can reportedly undertake 40 g turns close to sea level, when attacking a manoeuvring target.
