The S-400 Triumf, previously known as the S-300 PMU-3, is a mobile surface-to-air missile system developed in the 1990s by Russia's NPO Almaz as an upgrade to the S-300 family of missiles. From Wikipedia
India successfully intercepted all Pakistani missiles and drones during a coordinated attack, marking the first combat use of the S-400 system within its multi-layered defence strategy.
