IAF successfully conducts development trials of Astra missile

The Indian Air Force (IAF) successfully conducted developmental trials of indigenously developed Astra beyond visual range air-to-air missile (BVRAAM) over the Bay of Bengal, off the coast of Chandipur in Odisha.

Total of seven trials of Astra BVRAAM were conducted in various missions and two of them were against Pilotless Target Aircrafts (PTA) successfully fired from Sukhoi-30 MKI aircraft. They were final development flight trials of the missile, paving way for its early induction into IAF.

Astra Missile

Astra is air to air beyond visual range air-to-air indigenously developed by DRDO. It is one of the smallest weapon system developed by DRDO, having length of 3.8-metre and weighing 154kg. It is single stage solid fuelled missile and has payload capacity of 15 kg conventional explosives.

It can be launched from different altitudes and is capable of engaging targets at varying range and altitudes at both short-range targets (up to 20 km) in tail-chase mode and long-range targets (up to 80 km) in head-on mode. It is radar homing supersonic missile having maximum speed of Mach 4 (four times speed of sound).

It possesses high Single Shot Kill Probability (SSKP) making it highly reliable. It is all-weather missile with active radar terminal guidance, excellent electronic counter-counter measure (ECCM) features, smokeless propulsion and process improved effectiveness in multi-target scenario.

It has advance on-board electronic counter-measures that jam radar signals from enemy radar, making tracking of the missile difficult. It is fitted with terminal active radar-seeker and an updated mid-course internal guidance system that helps missile to locate and track targets.

The missile can be integrated with all fighter aircraft of IAF including Sukhoi-30 MKI, Mirage-2000, MiG-29, Jaguar and the Tejas Light Combat Aircraft (LCA).

3rd Generation ATGM NAG successfully test fired

The Defence Research and Development Organisation (DRDO) has successfully twice flight tested indigenously developed 3rd generation Anti-Tank Guided Missile (ATGM) Nag in Rajasthan.

During the test, ATGM Nag missile has successfully hit both the targets under different ranges and conditions with very high accuracy.

Comment

With these two successful trials and earlier test conducted in June 2017, complete functionality of Nag ATGM along with launcher system NAMICA has been established. It marks successful completion of development trials of Nag Missile.

Nag Missile

The ATMG Nag missile is one of five missile systems developed indigenously by DRDO under integrated guided missile development programme (IGMDP). The other four missiles developed under this programme include Agni, Akash, Trishul and Prithvi.

The Nag missile is third generation anti-tank guided missile which works on “fire and forget” principle. It has been equipped with highly advanced Imaging Infrared Radar (IRR) seeker along with integrated avionics. This technology is possessed by very few nations. It also possess advanced passive homing guidance system.

The missile has been designed mainly to destroy modern main battle tanks and other heavily armoured targets. It can be launched from land and air-based platforms. It has operational range of 500m to 4km (Land version) and 7-10km (when air-launched).

The helicopter launched version known of NAG missile is known as NAG (HELINA) can be fired from Dhruv advanced light helicopter (ALH) and HAL Rudra attack helicopter. The land-based version of missile is at present available for integration on the Nag missile carrier (NAMICA).
