S-500 Prometheus air defense system
Why in news?
Russia's S-500 Prometheus air defense system, an advanced successor to the S-400, is in discussions for potential acquisition by India, including co-production and technology transfer, amid Russian President Vladimir Putin's recent visit to New Delhi.
Key Facts
- Russian next-generation surface-to-air missile (SAM) system, known as S-500 Prometheus or 55R6M Triumfator-M, developed by Almaz-Antey.
- Designed to intercept ballistic missiles, hypersonic weapons (up to Mach 20 or 7 km/s), stealth aircraft, UAVs, cruise missiles, and low Earth orbit satellites.
- Range up to 600 km for anti-aircraft and 500 km for anti-ballistic missile defense; altitude up to 200 km into near-space.
- Can detect targets at 2,000 km (ballistic) or 800 km (airborne) and engage up to 10 hypersonic targets simultaneously with hit-to-kill interceptors like 77N6-N and 40N6M.
- Features advanced radars (91N6A(M), 96L6) and mobile components on BAZ trucks for rapid deployment.

Significance for India
- Enhances layered air defense beyond S-400 (already operational and proven in Operation Sindoor against Pakistani threats), countering China's hypersonic DF-21D/DF-26 and Pakistan's missiles.
- Russia offered joint production, technology transfer, and co-production under G2G deal to align with Make in India, potentially allowing India to export and bypass sanctions.
- Strengthens deterrence amid regional tensions; no confirmed procurement yet, as India prioritizes more S-400s, but interest persists post-S-400 success.
