- The ASAT missile destroyed a live satellite in Low Earth orbit (283-kilometre).
- As per DRDO, the missile is capable of shooting down targets moving at a speed of 10 km per second at an altitude as high as 1200 km.
There are 2 kinds of Missiles, Ballistic and Cruise
|Ballistic Missiles||Cruise Missiles|
|It follows a ballistic trajectory with the objective of delivering one or more warheads to a predetermined target.||It is a guided missile that remains in the atmosphere and flies the major portion of its flight path at approximately constant speed.|
|Target is predetermined. Fit for large targets.||Target can be mobile. More appropriate for small mobile targets.|
|Guided only during relatively brief periods of flight and the rest of its trajectory is unpowered and governed by gravity.||Are self-navigating|
|High altitude. Easy to track||Able to fly in extremely low-altitude trajectory. Makes it difficult to track|
Integrated Guided Missile Development Program(IGMDP)
ASTRA the first indigenously developed air-to-air missile was successfully flight-tested off the coast of Odisha.
- The Astra missile is developed by Defence Research and Development Organization (DRDO).
- It works on the Beyond Visual Range Air-to-Air Missile (BVRAAM) technology that enables the fighter-pilots to shoot precisely at the enemy targets which are beyond their visual range.
- The specifications of the missile are:
- Speed: over 5,555 km per hour or 4.5 mach
- Range: over 70 km,
- Payload/warhead capacity: 15 kg.
Air to Air Missile (AAM) is a missile fired from an aircraft for the purpose of destroying another aircraft or any airborne object.
AAM is broadly classified into 2 types depending on the range factor of the missile.
- Short Range Air to Air
Missile (SRAAM) or Within Visual Range Air to Air Missile (WVRAAM) – These
Missiles are designed to engage aerial targets within a range of 30 km.
Most of these missiles use infrared guidance and are called heat-seeking
missiles. These missiles are designed for better agility, hence they are also
called dogfight missiles.
- Beyond Visual Range Air to Air Missile (BVRAAM) – These missiles can hit targets beyond the range of 37 Km. These are radar-guided missiles. They don’t use infrared detector since the infrared signatures of aerial targets would be too weak at long ranges.
Astra is the Beyond Visual Range Air to Air Missile (BVRAAM) developed by DRDO (Defence Research and Development Organisation). It can engage aerial targets at a range of 80 km – 110 km. It has been integrated with Sukhoi 30 Mki, Mirage 2000, LCA, MiG-29 fighter aircraft.
Quick Reaction Surface-to-Air missiles (QRSAM)

- AAD was recently successfully test-fired from a test range in Odisha.
Mission Shakti was undertaken to develop highly-potent Anti-satellite weapons (ASAT). It is a joint programme of the Defence Research and Development Organisation (DRDO) and the Indian Space Research Organisation (ISRO). Anti-satellite (ASAT) System is missile-based system to attack moving satellites.
- ASAT propels India to the coveted space-superpower league.
- India will now have the power to decimate satellites for pure military and strategic purpose.
- With this missile, India will have the capability to interfere with satellites or engage in direct attacks.
- ASAT missile can be air, sea or land-based.
Why is it made to destroy Satellites?
- Satellites assume a great importance now-a days, because it is a part of critical civil and defence infrastructure of any country, manifested in the fact that a large number of crucial applications are dependent on it.
- These include navigation systems, communication networks, broadcasting, banking systems, stock markets, weather forecasting, disaster management, land and ocean mapping and monitoring tools, and military applications.
- Destroying a satellite would render these applications useless. It can cripple enemy infrastructure without causing any threat to human lives.
- Outer space is also emerging as the fourth arena of warfare. Hostile state and non-state actors can therefore damage Indian space assets.
- The ASAT capability has created some deterrence against potential hostile behaviour against Indian interests.
- The Kessler syndrome (also called the Kessler effect, collisional cascading or ablation cascade), proposed by the NASA scientist Donald J. Kessler in 1978, is a scenario in which the density of objects in low Earth orbit (LEO) is high enough that collisions between objects could cause a cascade where each collision generates space debris that increases the likelihood of further collisions.
- One implication is that the distribution of debris in orbit could render space activities and the use of satellites in specific orbital ranges impractical for many generations.
