Catch Your Opponent Unaware With IRST
One of the major Gripen E’s capabilities include the new sensor IRST (Infra Red Search and Track). And what makes IRST one of the most advanced technology is the fact that it can silently detect its targets.
But how does IRST catch an opponent unawares?
IRST is an electro-optical system mounted on top of the nose, just in front of the canopy, and is looking forward in a wide sector registering heat emissions from other aircraft, helicopters and from objects on the ground and sea surface.
IRST is a passive sensor, which means it never emits any energy. It only listens for energy coming from other sources. The tactical advantage of a passive sensor is that it will not give your position away. Opponents will have no indication whatsoever that Gripen E is using its IRST to monitor their activities.
Saab successfully conducted Gripen’s first flight with IRST four years ago. IRST enables detection and tracking of enemy targets including aircraft, naval vessels and ground vehicles.
