Integrated Guided Missile Development Programme (IGMDP)

Science & Technology › Defence Technology and Missile Systems · Topic 16.2

The Integrated Guided Missile Development Programme, IGMDP, was approved by the Government of India in 1983 under the leadership of Dr A P J Abdul Kalam at the Defence Research and Development Laboratory, Hyderabad, to make India self-reliant in missiles through a single coordinated plan instead of separate projects. It aimed at five missile families: Prithvi, a short range surface to surface missile; Agni, an intermediate range ballistic missile; Trishul, a short range low level surface to air missile; Akash, a medium range surface to air missile; and Nag, a third generation anti-tank guided missile. The programme developed also related technologies such as solid propellants, guidance and composites. The Government declared it completed in January 2008.

Where Does It Fit?

This topic follows the account of missile types. It explains the programme that created India’s missile family, which the next topic on Indian missile systems describes one by one. Previous topic: Classification of Missiles: Ballistic vs Cruise Missiles. Next topic: India’s Missile Systems: Prithvi, Trishul, Nag, Akash, Agni Series.

What Was the IGMDP and What Did It Aim to Do?

Aspect	Details
Approval	1983, by the Government, after the Defence Research and Development Organisation proposed a package under Dr Kalam to end dependence on imports
Leader	A P J Abdul Kalam, who later became Missile Man of India and the 11th President of India (2002 to 2007)
Nodal laboratory	Defence Research and Development Laboratory, Hyderabad, with many other DRDO labs and industry
Approach	Parallel development of several missiles under one umbrella to share technologies, rather than one project at a time
Prithvi	Surface to surface, first IGMDP missile tested in February 1988
Agni	Started as a re-entry technology demonstrator; first flight on 22 May 1989 and later developed as a strategic missile
Completion	Declared complete on 8 January 2008 after the five systems were developed, with further work taken up as separate projects

What Did the IGMDP Achieve and Why Was It Important?

Trishul: short range, low level quick reaction surface to air missile for the three services; development was stopped as the missile did not meet needs, though its technologies were used elsewhere
Akash: medium range surface to air missile inducted in the Air Force in 2008 and the Army in 2015
Nag: third generation fire and forget anti-tank missile with imaging infrared seeker
Technology base: solid propellant motors, ring laser gyroscopes, composites, radar seekers and test ranges
Industry: Bharat Dynamics Limited in Hyderabad produces many of the missiles
Response to sanctions: the programme grew while India faced technology denial regimes
Strategic effect: gave India a credible missile base for deterrence after the 1998 nuclear tests
Later programmes: Astra, BrahMos with Russia, Pralay, Nirbhay and hypersonic systems follow from this base

What Else Should You Remember?

DRDO origins: set up in 1958 and now the main defence research agency under the Ministry of Defence
Research Centre Imarat: RCI at Hyderabad makes missile avionics and guidance systems
Advanced Systems Laboratory: ASL in Hyderabad develops long range missile structure and propulsion
Defence Research and Development Laboratory: DRDL leads the missile design
Integrated Test Range: a testing facility in Chandipur, Odisha
Missile Man: a title given to Dr Kalam for his missile work
Agni technology demonstrator: first flight was a test of re-entry technology, with a Prithvi first stage as booster
Kalam and Bharat Ratna: Dr Kalam received the Bharat Ratna in 1997
Foreign help: early programme used some foreign technology but India developed most of it
Parallel development: a modular approach that shared guidance and propulsion
Science of guidance: inertial and radar based guidance, later GPS and NavIC
Delays and cost: projects such as Trishul and Nag took longer than expected
Production partners: Bharat Electronics, Larsen and Toubro and private firms
Lessons: integrated planning, user involvement and testing at the right time
Current role: DRDO continues missile work in cluster labs, as in India’s Missile Systems
Defence indigenisation: positive indigenisation lists and Atmanirbhar Bharat now support domestic production
Export: Akash was approved for export, and BrahMos has been exported to the Philippines
Technology denial: after the 1974 nuclear test and later in 1998, India faced restrictions on dual-use technology, which pushed indigenous development
Kalam as scientific adviser: Dr Kalam later served as Principal Scientific Adviser to the Government from 1999 to 2001
Wings of Fire: Dr Kalam wrote an autobiography of that name, with Arun Tiwari

Why Does It Matter for the Exam?

Year and leader: 1983, Kalam
Missiles: Prithvi, Agni, Trishul, Akash, Nag
Lab: DRDL Hyderabad
Current affairs link: Agni tests and export of Akash
Common errors: adding BrahMos or Astra to IGMDP

As an analytical point, the IGMDP is cited as a model of mission mode technology development, with a clear leader, time bound goals and shared technologies. Its slow areas, such as Trishul and aircraft engines, show the limits of domestic development without maturity in some technologies.

Why Is This Topic Important?

Frequently Asked Questions

What is the Integrated Guided Missile Development Programme?

The Integrated Guided Missile Development Programme was a mission approved in 1983 and led by Dr A P J Abdul Kalam at DRDO to develop a family of guided missiles in India. It produced the Prithvi, Agni, Trishul, Akash and Nag missiles and was declared complete in January 2008.

Which missiles were developed under IGMDP?

The five missile systems were Prithvi, a short range surface to surface missile, Agni, an intermediate range ballistic missile, Trishul, a short range surface to air missile, Akash, a medium range surface to air missile, and Nag, a third generation anti-tank guided missile.

Who led the IGMDP?

Dr A P J Abdul Kalam led the programme as its chief at the Defence Research and Development Laboratory in Hyderabad. His role earned him the name Missile Man of India. He later became the 11th President of India, serving from 2002 to 2007, and received the Bharat Ratna in 1997.

Is BrahMos part of the IGMDP?

No. BrahMos is a separate project, a joint venture of India's DRDO and Russia's NPO Mashinostroyenia, formed in 1998 as BrahMos Aerospace. The IGMDP covered only the five systems Prithvi, Agni, Trishul, Akash and Nag, which were all developed within India.

When was the IGMDP closed?

The Government declared the programme completed on 8 January 2008, after the five systems had been developed and inducted or taken to advanced stages. Later missile work, such as new versions of Agni and Akash, was taken up as separate projects by DRDO.
