Drdo’s Major Missile Programmes and Collaborations

India’s indigenous missile development program transformed the country into a key missile power with complete coverage across land, air, sea, and sub-surface domains. Spearheaded by the Defence Research and Development Organisation (DRDO), the missile ecosystem evolved from early import dependencies into advanced indigenous design, production, and international joint ventures. Strategic systems range from long-range ballistic platforms and supersonic cruise missiles to quick-reaction air defense systems and anti-tank guided weapons.

Integrated Guided Missile Development Programme (IGMDP)

Sanctioned in 1983 under the leadership of Dr. A.P.J. Abdul Kalam, the Integrated Guided Missile Development Programme laid the foundation for national missile technology self-reliance. The program officially concluded in 2008 after successfully achieving operational capability across five core baseline missile systems represented by the acronym PATNA.

• Prithvi: Short-range, surface-to-surface tactical ballistic missile utilizing liquid and solid propulsion systems.
• Agni: Re-entry vehicle and ballistic missile platform initially launched as a technology demonstrator before evolving into a multi-tiered strategic deterrent series.
• Trishul: Short-range, quick-reaction surface-to-air missile designed to counter low-level aerial attacks.
• Nag: Third-generation, top-attack anti-tank guided missile featuring fire-and-forget capability with imaging infrared homing.
• Akash: Medium-range surface-to-air missile system equipped with multi-target capability and high-energy ram-rocket propulsion.

Strategic Ballistic Missile Systems

India maintains a credible nuclear triad powered by land-based and sea-based ballistic missile systems developed by DRDO.

Agni Series

The Agni family forms the backbone of land-based strategic deterrence.

• Agni-I to Agni-IV: Covers operational strike ranges from 700 km to 4,000 km using solid-propellant stage engines and inertial navigation networks.
• Agni-V: Intercontinental Ballistic Missile (ICBM) with a strike range exceeding 5,000 km. It features canisterized road-mobile launching systems and Multiple Independently Targetable Re-entry Vehicle (MIRV) technology under Project Divyastra.
• Agni-P (Prime): New-generation, two-stage solid-fueled canisterized missile with advanced guidance systems covering ranges between 1,000 km and 2,000 km.

Tactical and Submarine-Launched Missiles

• Prithvi-II: Single-stage liquid-fueled tactical missile with an operational range of 250 km to 350 km.
• Pralay: Solid-fueled, short-range surface-to-surface quasi-ballistic missile with a range of 150 km to 500 km, designed to alter its flight path mid-air to defeat interceptors.
• K-15 (Sagarika): Submarine-Launched Ballistic Missile (SLBM) with a 750 km range, integrated into INS Arihant class submarines.
• K-4: Two-stage solid-fueled SLBM with a 3,500 km strike range, enhancing sea-based second-strike capability.

Cruise Missiles and Tactical Systems

Cruise Missile Platforms

• BrahMos: Supersonic cruise missile operating on a two-stage propulsion principle (solid booster and liquid ramjet) with speeds up to Mach 2.8 and ranges extended from 290 km up to 800 km.
• Nirbhay: Indigenous long-range subsonic cruise missile powered by a solid booster and turbojet engine, capable of loitering and terrain-hugging flight at low altitudes up to 1,000 km.
• Long-Range Land-Attack Cruise Missile (LRLACM): Advanced indigenous stand-off land-attack cruise missile platform developed for multi-service deployment.

Air Defense and Anti-Tank Missiles

• Astra: Beyond Visual Range Air-to-Air Missile (BVRAAM) equipped with active radar homing, integrated on Su-30MKI and Tejas fighter jets. Astra Mark-I reaches ranges beyond 110 km, while Astra Mark-II features dual-pulse rocket engines for extended ranges up to 160 km.
• Akash-NG (New Generation): Surface-to-air missile with a dual-pulse solid motor, active electronically scanned array seeker, and reaction times targeting threats up to 70 km.
• HELINA / Dhruvastra: Helicopter-launched air-to-surface version of the Nag missile designed for integration on Advanced Light Helicopters.
• MPATGM: Man-Portable Anti-Tank Guided Missile built with tandem HEAT warheads for infantry anti-armor operations.
• RudraM Series: Air-to-surface anti-radiation missiles designed for Suppression of Enemy Air Defences (SEAD) by homing in on radiation-emitting radar and communication nodes.

International Collaborations and Joint Ventures

DRDO partners with international aerospace leaders to co-develop advanced missile technologies and air defense systems.

Key Missile Systems Technical Summary

Essential Facts to Remember

• The Integrated Guided Missile Development Programme (IGMDP) started in 1983 under Dr. A.P.J. Abdul Kalam and concluded in 2008.
• The acronym PATNA denotes the five original IGMDP missiles: Prithvi, Agni, Trishul, Nag, and Akash.
• BrahMos Joint Venture takes its name from two rivers: the Brahmaputra in India and the Moskva in Russia.
• The K-series submarine-launched ballistic missiles are named after former Indian President Dr. A.P.J. Abdul Kalam.
• Agni-V features canister launch technology and Multiple Independently Targetable Re-entry Vehicle (MIRV) capability.
• India’s Ballistic Missile Defence (BMD) program operates a two-layer shield: Prithvi Air Defence (PAD) for exo-atmospheric interception and Advanced Air Defence (AAD) for endo-atmospheric interception.
• Astra represents India’s first indigenous Beyond Visual Range Air-to-Air Missile integrated onto frontline combat aircraft.
• Barak-8 was co-developed by DRDO and Israel Aerospace Industries (IAI) to protect naval and ground assets against aerial threats.
