Important points to remember about Indian defence for SSC Exams Part -III

Dr Abdul Kalam, who had previously been the project director for the SLV-3 programme at ISRO, was inducted as the DRDL director in 1983 to conceive and lead it. 4 projects, to be pursued concurrently, were born under the IGMDP.

  • Short range surface to surface missile (Prithvi).
  • Short range low level surface to air missile (Trishul).
  • Medium range surface to air missile (Akash).
  •  3rd generation anti-tank missile (Nag).

The Agni missile was initially conceived in the IGMDP as a technology demonstrator project in the form of a re-entry vehicle and was later upgraded to a ballistic missile with different ranges.

Prithvi Missile Series

  • Surface to surface
  • short Range Ballistic Missile (SRBM) developed by DRDO.


Agni Missile Series

  • Agni Missile  was first tested at the interim test range in Chandipur in 1989 and was capable of carrying a conventional payload of 1000 kg or a nuclear warhead.
  • The Agni series of missiles are guided by Ring Laser Gyro (RLG) based Inertial Navigation System (INS) and the most modern and accurate Micro Navigation System (MINS).


  • This is a two-stage Agni technology demonstrator, with a solid-fuel first stage. It is capable of carrying a conventional payload of 1000 kg. Agni-I has a range of 700-1250 km.


  • It is the improved version of Agni-I. It uses solid propellant in both of its two stages. Agni-II has a range of 2000-3000 km. It can carry a payload of 750-1000 kg.


  • It uses solid propellant in both stages.
  • Agni-III has a range of more than 3000 km and can take a warhead of 1.5 tonnes.


  • It has a range of 2500-4000 km.
  • This missile can carry nuclear payload weighing close to a tonne.


  • It is a solid fueled Inter Continental Ballistic Missile (ICBM) developed by DRDO.
  • It has a range of 5000-5500 km and can carry a nuclear warhead of 1500 kg.


  • It will be capable of being launched from submarines as well as from land and will have a strike-range of 8000-10000 km with MIRV warheads.


  • This is a medium range surface to air missile defence system developed by the DRDO. It can target aircraft up to 30 km away.
  • Akash files at supersonic speed, reaching around Mach 2.5. The missile is supported by a phase-arrayed fire control radar called the Rajendra.

Trishul Missile System

  • Trishul (means trident) is the name of a short range surface to air missile. It has a range of 9 km. It is designed to be used against low level (sea skimming) target at short range.

Some Strategically Important Missiles Outside the IGHDP


  • It is an active radar homing Beyond-Visual-Range Air to Air Missile (BVRAAM) developed by the DRDO.
  • Range 80-110 km.


  •  Surface to Air Missile
  •  The naval and air force variants will be called Revati and Rohini respectively.


  • It is a long range, subsonic stealth cruise missile and will arm 3 services, the Indian Army, the Indian Navy and the Indian Air Force.
  • Nirbhay will supplement BrahMos in the sense that is would enable delivery of warheads further than the 290 km range of BrahMos.

Novator K-100

  • It is an Air to Air missile designed as an AWACS killer for ranges up to 300-400 km.
  • It is likely to be used in India’s Su-30 MKI aircraft.
  • joint venture project of India and Russia.


  • It is a solid fuelled surface to surface guided short range tactical ballistic missile developed by DRDO.
  • Operational Range-150 km.

Sagarika /K-15

  • It is a nuclear capable Submarine Launched Ballistic Missile (SLBM) with a range of 700 km. It belongs to the K Missile family. It will be integrated with India’s nuclear powered Arihant class submarine.
  • Operational Range – 700 km with 1000 kg warhead and 1900 km with 180 kg warhead.

Shaurya Missile

  • It is a canister launched hypersonic surface to surface tactical ballistic missile developed by the DRDO. Operational range 600 km with 700 kg warhead and 1900 km with 180 kg warhead.

Dhanush (Means Bow)

  • It is a naval vriant of the surface to surface Prithvi II missile with an operational range up to 350 km. It is capable of carrying both conventional as well as nuclear warheads with payload capacity of 500 kg and can be launched from ships.


  • It is an Israeli designed missile. India purchased this missile system from Israel. It is a Surface to Air missile meant to protect ships against aircraft, anti-ship missiles, UAV’s etc.


  • It is a supersonic cruise missile that can be launched from submarines, ships, aircraft or has a maximum range of 290 km. It is the world’s fastest cruise missile and can also evade enemy radar by skimming close to the land and sea surface.


  • It is a surface based, solid and liquid propellant ballistic missile. It is speculated to have a range between 10000 to 16000 km.
  • Originally conceived as a defence against nuclear armed Intercontinental Ballistic Missiles (ICBMs), its application has broadened to include short-ranged non-nuclear tactical and theater missiles.
