Introduction
The India-Pakistan conflict of 2025 has reignited global concerns about a potential nuclear confrontation in South Asia. With Pakistan’s recent missile and drone attacks on Jammu and Kashmir—and the retaliatory air defence responses from India—many are asking: Can India’s missile defence system stop a nuclear attack?
India’s Missile Defence: A Four-Tiered Shield
India has developed a sophisticated, layered Ballistic Missile Defence (BMD) system that includes:
- Prithvi Air Defence (PAD): Designed to intercept high-altitude missiles.
- Advanced Air Defence (AAD): Targets lower-altitude ballistic threats.
- Barak-8 System: Jointly developed with Israel, protects against cruise missiles and drones.
- Surface-to-Air Missiles (SAMs): Deployed for tactical air defence.
What Happened During the May 2025 Escalation?
Following India’s Operation Sindoor, Pakistan launched coordinated missile and drone attacks targeting 15 Indian cities, military installations, and bases in Jammu. Reports confirm that India’s air defence shot down multiple targets, including three Pakistani fighter jets—one of them a US-supplied F-16.
Can the Missile Defence System Stop Nuclear Missiles?
India’s BMD system is capable of intercepting incoming ballistic threats, including nuclear-capable missiles, but the challenge lies in:
- Speed and Range: ICBMs travel at hypersonic speeds, limiting interception windows.
- Multiple Warheads: MIRVs (Multiple Independently Targetable Re-entry Vehicles) can overwhelm defences.
- Decoys and Countermeasures: Many nuclear missiles deploy decoys to confuse interceptors.
Hence, while India’s defences reduce risk, they do not guarantee full protection against a large-scale nuclear strike.
India’s Strategic Deterrence Posture
India follows a ‘No First Use’ nuclear doctrine. However, its deterrence lies in a credible second-strike capability—powered by nuclear triad assets including Agni-5 ICBMs with ranges of 5,000–8,000 km, nuclear submarines like INS Arihant, and bomber aircraft.
Role of International Diplomacy and Technology Partners
India has partnered with nations like France and Israel to develop advanced systems. Though the U.S. has historically limited high-end missile tech exports to India, the strategic dialogue continues to evolve, especially as India takes a more central role in counterbalancing China.
Conclusion: A Shield, Not a Guarantee
India’s missile defence system provides a robust response capability against conventional and some nuclear threats. However, no missile defence—no matter how advanced—is foolproof against a determined full-scale nuclear assault. The key lies in deterrence, diplomacy, and continued technological advancement.
