Astra (missile)
Astra ((サンスクリット:अस्त्र), Astra: Throwing weapon) is an active radar homing beyond-visual-range air-to-air missile (BVRAAM) developed by the Defence Research and Development Organisation (DRDO), India. Astra is designed to be capable of engaging targets at varying range and altitudes allowing for engagement of both short-range targets (up to 20 km) and long-range targets (up to 80 km) using alternative propulsion modes. Except for a failure in one test, the missile has successfully completed all its tests. The missile was last tested on 18 March 2015 from a Su-30MKI fighter against a simulated live target.〔http://www.newindianexpress.com/states/odisha/India-Successfully-Test-Fires-Air-to-Air-Astra-Missile/2015/03/19/article2721103.ece〕 Astra uses a smokeless propulsion system.
As per a defence scientist, the missile is technologically more sophisticated than the nuclear capable Agni missile series of strategic ballistic missiles.〔http://www.newindianexpress.com/states/odisha/India-Successfully-Test-Fires-Air-to-Air-Astra-Missile/2015/03/19/article2721103.ece〕
== Description ==
The missile guidance is provided by a terminal active radar-seeker and an updated mid-course internal guidance system, which locates and tracks targets. On-board electronic counter-measures jam radar signals from enemy radar, making tracking of the missile difficult. The performance characteristics of the missile are similar to the R-77RVV-AE (AA-12) and Super 530D, both currently used by the IAF. It is 3.8 metres long and is narrower in front of the wings. The propellant used is HTPB (solid-fuel). The warhead is a 15 kg HE (high-explosive) which is activated by a proximity fuse. The missile's maximum speed is Mach 4 and can attain maximum altitude of 20 km. The missile can handle 40 g turns near sea level while attacking a manoeuvring target. Astra has ECCM features and has improved effectiveness in multi-target scenarios. It can be launched in both autonomous and buddy mode operation and can achieve lock-on on its target before or after it is launched.〔(【引用サイトリンク】title=DRDO's international coming out party in Seoul features new Pragati tactical missile system )〕
