S-400 Triumf
The long-range shield over Indian airspace.
About the Triumf
The S-400 Triumf, previously known as the S-300 PMU-3, is a mobile surface-to-air missile (SAM) system developed in the 1990s by Russia's NPO Almaz as an upgrade to the S-300 family of missiles. The S-400 was approved for service on 28 April 2007 and the first battalion of the systems assumed combat duty on 6 August 2007. Its longest-ranged interceptor missile, the 40N6, has a purported range of 400 km.
Service history
India signed for five S-400 squadrons in 2018 for $5.43 billion, accepting the risk of US sanctions under CAATSA to do so. Deliveries began in 2021 and were slowed by the war in Ukraine. The system engages targets out to 400 km at up to 30 km altitude, and was used operationally during the May 2025 exchanges with Pakistan.
