The Integrated Guided Missile Development Programme (IGMDP) was started in 1983 and completed in March 2012. When the Akash surface-to-air missile (SAM) entered service with the Indian Air Force (IAF) in September 2012, it had taken 30 years to develop and built. Shaken by this delay, the Navy and the IAF sponsored a new development model for their next-generation missiles, which would see the Defence Research & Development Organisation (DRDO) moving away from indigenous technology development, and operating instead as a project manager. Effectively, the DRDO had been handed the coordination role traditionally played by the defence ministry (MoD).

There have been some offer for joint collaboration/cooperation in the field of development of missile system from various countries. One joint development project already exist for Long Range – Surface-to-Air Missile (LR-SAM) with Israeli Aerospace Industry (IAI), Israel. Indian defence scientists are involved in the design, development, test & evaluation and productionisation of missile and its sub-systems in collaborative mode.

The Integrated Guided Missile Development Programme (IGMDP), launched in 1983, was headed by Dr. Avul Pakir Jainulabdeen Abdul Kalam, who made significant contribution as Project Director to develop India's first indigenous Satellite Launch Vehicle (SLV-III) which successfully injected the Rohini satellite in the near earth orbit in July 1980 and made India an exclusive member of Space Club. He was responsible for the evolution of ISRO's launch vehicle program, particularly the PSLV configuration. After working for two decades in ISRO and mastering launch vehicle technologies, Dr. Kalam took up the responsibility of developing Indigenous Guided Missiles at Defence Research and Development Organisation as the Chief Executive of Integrated Guided Missile Development Programme (IGMDP). He was responsible for the development and operationalisation of AGNI and PRITHVI Missiles.

The following missiles and technology demonstration systems were developed under Integrated Guided Missile Development Programme (IGMDP) – Agni, a technology demonstration project for re-entry technology; Prithvi, surface-to-air missile with 150, 250 & 350 Km range for Army, Air Force and Navy; Akash, surface-to-air missile with a range of 25Km and multi-target handling system; Nag, third generation “fire & forget” and “top attack” anti-tank missile; Development of Trishul missile system has been completed as technology demonstration.

By 1999 the Government had approved the development of the Second Phase of AGNI. This follows successful completion of the Phase-I of AGNI during which three tests were conducted demonstrating re-entry technology. The PRITHVI missile of the Defence Research and Development Organisation (DRDO) had already been inducted. The other missiles of DRDO under its Integrated Guided Missile Development Programme were in various stages of development. The short range surface-to-air missile TRISHUL was in the final stage of development tests. The medium range surface-to-air missile AKASH and the third generation anti-tank guided missile NAG were entering the final stage of guidance flight trials.

By 2003 all the guided missiles being developed under Integrated Guided Missile Development Programme (IGMDP) had gone through successful flight trials. Prithvi I had been completed and inducted. Prithvi II and Dhanush were in progress of induction in Army, Air Force and Navy respectively. Akash and Nag had gone through successful flight test recently. Nag, anti tank missile, had been proved for day and night capability with advanced technology seeker. Agni and BrahMos had been flight tested.

By 2008 only one project i.e. NAG, third Generation Anti Tank Missile, remained under development as part of Integrated Guided Missile Development Programme. The probable date completion was December 2008. User Trials of NAG third generation anti-tank missile were scheduled during 2nd half of 2008.
