The S-3 Viking was the U.S. NAVY standard anti-submarine aircraft operating from aircraft carriers since the mid-70s.

This big twin-jet plane is equipped with cutting-edge electronics to control sea missions and surveillance in close contact with ships and helicopters entrusted to protect aircraft-carriers. Viking II has an ample range, thanks to in-flight refuelling to ensure long patrol periods.

Additionally, Viking II can transport plenty of material in its large hold: torpedoes, depth charges, and an enormous quantity of buoys to receive underwater signals..
