Know 31 facts about Akash missile nuclear warhead capable missile made by DRDO BEL

Know 31 facts about Akash missile nuclear warhead capable missile made by DRDO BEL

1. Akash missile is India's medium range surface-to-air missile defense system developed by the Defense Research and Development Organization (DRDO) and Bharat Electronics Limited (BEL)

2. The first test flight of Akash missile was conducted in 1990, with development flights up to March 1997.

3. In December 2007, the Indian Air Force completed user trials for this missile.

4. The Akash system is comparable to the Patriot system

5. Akash is a surface-to-air missile with an intercept range of 30 km.

6. It has a launch weight of 720 kg, a diameter of 35 cm and a length of 5.78 meters.

7. Akash flies at supersonic speed, reaching around Mach 2.5.

8. It can reach an altitude of 18 km

9. The Akash Missile Development cost of INR 1,000crore ($200 million), including the project sanction of INR 600 crore ($120 million)

10. Akash missile can target aircraft up to 30 km away, at altitudes up to 18,000 m.

11. Akash can be fired from both tracked and wheeled platforms.

12. Akash can be launched from static or mobile platforms, including a battle tank

13. Akash can destroy manoeuvring targets such as Unmanned Aerial Vehicles (UAVs), fighter aircraft, cruise missiles and missiles launched from helicopters.

14. Communications between the various vehicles are a combination of wireless and wired links. The entire system is designed to be set up quickly

15. Akash is said to be capable of both conventional and nuclear warheads, with a reported payload of 60 kg.

16. Akash missile is capable to destroy both aircraft and warheads from ballistic missiles.

17. An on-board guidance system coupled with an actuator system makes the missile maneuverable up to 15g loads and a tail chase capability for end game engagement.

18. A digital proximity fuse is coupled with a 55 kg pre-fragmented warhead, while the safety arming and detonation mechanism enables a controlled detonation sequence.

19. A self-destruct device is also integrated. It is propelled by an Integrated Ramjet Rocket Engine. The use of a ramjet propulsion system enables sustained speeds without deceleration throughout its flight.

20. The Missile has command guidance in its entire flight.

21. The missile battery is described as being able to track and attack several targets simultaneously.

22. An Akash battery comprises four 3D phased array radars and four launchers with three missiles each, all of which are interlinked. Each radar is able to track 16 targets simultaneously and control a launcher with 3 missiles. Hence it is reported to be able to detect 100 and track 64 targets and simultaneously attack any 8 of those targets at one time.

23. The Akash Weapon System architecture is based on a Group Headquarters and a number of batteries.

24. Akash has an advanced automated functioning capability. The 3D CAR automatically starts tracking targets at a distance of around 150 km providing early warning to the system and operators. The target track information is transferred to GCC. GCC automatically classifies the target. BSR starts tracking targets around a range of 100km. This data is transferred to GCC. The GCC performs multi-radar tracking and carries out track correlation and data fusion. Target position information is sent to the BLR which uses this information to acquire the targets.

25. The BCC which can engage a target(s) from the selected list at the earliest point of time is assigned the target in real time by the GCC. The availability of missiles and the health of the missiles are also taken into consideration during this process. Fresh targets are assigned as and when intercepts with assigned targets are completed. A single shot kill probability of 88% has been achieved by the system taking into consideration various parameters of the sensors, guidance command, missile capabilities and kill zone computations.

26. The missile is guided by a phased array fire control radar called 'Rajendra' which is termed as Battery Level Radar (BLR) with a tracking range of about 60 km

27. The radar has advanced ECCM features. The Rajendra derivative on a BMP-2 chassis and to be used by the Indian Air Force is known as the Battery Level Radar-II whereas that for the Army is based on a T-72 chassis and is known as the Battery Level Radar-III.

28. The Army version also consists of the Battery Surveillance Radar (BSR). BSR is a track vehicle based, long range sensor, interfaced with the BCC. It can detect and track up to 40 targets in range and azimuth up to a range of 100km.

29. The total Indian Air Force orders thus far consist of 8 squadrons making a total of 1,000 missiles.

30. In April 2011, IAF announced that 2 squadrons will be based near Pune and Gwalior. Akash Squadrons are also to be deployed in the North-East.

31. Report in March 2011 indicates the Indian Army has ordered 2 Akash regiments --approximately 2,000 missiles-- worth INR14,000 crore ($3.1 billion).

Missiles are dangerous. India may not be so advanced with so many failed rocket launches.
