Why in News: India successfully test-launched the short-range ballistic missile Agni-1 from the Integrated Test Range (ITR), Chandipur, Odisha on May 22, 2026. The launch was conducted by the Strategic Forces Command (SFC) and validated all operational and technical parameters. The periodic user trial confirms continued operational readiness of the system in India’s nuclear arsenal.
About Agni-1
Technical Profile
| Parameter | Specification |
|---|---|
| Class | Short-Range Ballistic Missile (SRBM) |
| Range | 700-1,200 km |
| Configuration | Single-stage, solid-fuelled |
| Mobility | Road and rail-mobile (TEL — Transporter-Erector-Launcher) |
| Payload | Up to ~1,000 kg; conventional or nuclear-capable |
| First inducted | 2007 |
| Developer | DRDO (under IGMDP) |
Agni-1 was developed to fill the operational gap between the Prithvi series (150-350 km) and Agni-2 (~2,000 km). Its solid-fuel configuration provides rapid launch readiness and higher survivability compared to liquid-fuelled predecessors.
The Agni Series — Comparison
| Missile | Range | Stages / Fuel | Year Inducted | Key Feature |
|---|---|---|---|---|
| Agni-1 | 700-1,200 km | Single-stage, solid | 2007 | SRBM, road/rail mobile |
| Agni-2 | ~2,000 km | Two-stage, solid | 2004 | MRBM |
| Agni-3 | ~3,500 km | Two-stage, solid | 2011 | IRBM |
| Agni-4 | ~4,000 km | Two-stage, solid | 2014 | Lighter, road-mobile IRBM |
| Agni-5 | >5,000 km | Three-stage, solid | 2018 | ICBM-class; MIRV via Mission Divyastra (March 11, 2024) |
| Agni-Prime (Agni-P) | 1,000-2,000 km | Two-stage, solid | Under induction | MaRV-capable; replaces Agni-1/Agni-2 |
| Agni-6 (planned) | >10,000 km | Multi-stage | Under development | Heavy ICBM |
Mission Divyastra on March 11, 2024 was India’s first successful flight test of Agni-5 with Multiple Independently-targetable Re-entry Vehicles (MIRV) capability — joining a select club (US, Russia, UK, France, China) with this technology.
Integrated Test Range (ITR), Chandipur
- Located in Balasore district, Odisha, along the Bay of Bengal
- Operational since 1989
- Premier facility for testing tactical and strategic missile systems
- Houses Launch Complex (LC)-III, LC-IV, LC-V among others
- Adjacent to Dr. APJ Abdul Kalam Island (formerly Wheeler Island) — used for longer-range strategic launches
Integrated Guided Missile Development Programme (IGMDP)
- Launched: 1983
- Father of the programme: Dr. APJ Abdul Kalam (then DRDO chief)
- Officially completed: January 8, 2008
- Five missile programmes:
| Missile | Type |
|---|---|
| Prithvi | SRBM (surface-to-surface) |
| Agni | IRBM / ICBM family |
| Akash | Medium-range SAM |
| Trishul | Short-range SAM |
| Nag | Third-generation ATGM |
Strategic Forces Command (SFC)
- Established on January 4, 2003 under the Nuclear Command Authority (NCA)
- Headquartered in New Delhi
- Tri-service formation managing India’s land-, sea- and air-based nuclear arsenal
- Headed by a three-star officer (rotational among Army, Navy, IAF)
- NCA chaired by the Prime Minister, advised by the Political Council and Executive Council
India’s Nuclear Doctrine (2003)
Adopted by the Cabinet Committee on Security (CCS) in January 2003, the doctrine rests on the following pillars:
- Credible Minimum Deterrent (CMD)
- No-First-Use (NFU) — first formalised in 2003
- Massive retaliation to inflict unacceptable damage
- Civilian political control over nuclear weapons (via NCA)
- Continued moratorium on nuclear testing (since Pokhran-II, May 1998 — Operation Shakti)
- Commitment to global, verifiable nuclear disarmament
Comparison with Adversaries’ Systems
| Country | Notable SRBM/IRBM | Range | Doctrine |
|---|---|---|---|
| Pakistan | Shaheen-I | 750 km | Full-Spectrum Deterrence; rejects NFU |
| Shaheen-II | 2,500 km | ||
| Ababeel | 2,200 km | MIRV claimed | |
| China | DF-21 | 1,500-2,150 km | Declared NFU (with caveats) |
| DF-26 | 4,000 km | ||
| DF-31 / DF-41 | 10,000+ km | ||
| India | Agni-1 | 700-1,200 km | NFU; CMD |
| Agni-5 (MIRV) | >5,000 km |
Strategic Context: Post-Operation Sindoor
Following Operation Sindoor (May 2025) — India’s calibrated strikes against terror infrastructure across the LoC and IB — periodic Agni-class trials serve as credibility signalling to adversaries. Routine user trials demonstrate continued operational readiness of India’s strategic deterrent without escalating tensions.
