The Indian Air Force on Thursday released its first-ever video showing an S-400 air defence missile system in action. In an apparent reference to Operation Sindoor, the missile in flight was tagged as having carried out the “longest ever air kill recorded in military history”. The Russian-origin S-400 system played a key role in Operation Sindoor against Pakistan in May last year and had brought down a Pakistan Air Force aircraft around 300 km away, deep inside Pakistani territory. “Enemy may be out of reach, but is never out of sight,” the IAF said in the video released on Thursday. The footage includes a radar image detecting an approaching jet and activating the air defence mechanism. The missile footage is not from Operation Sindoor but is part of promotional material for the upcoming Vayu Shakti exercise, scheduled to be held on February 27 in Rajasthan.
