Jet aircraft is used in the detection and attack of submarines, and as an armed scout in the anti-surface role. Extremely versatile, the aircraft is also equipped for tanking, mining, and limited electronic surveillance.
Modified from the earlier S-3A Viking, the S-3B's high speed computer system processes information generated by the acoustic and non-acoustic target sensor systems. This includes a new Inverse Synthetic Aperture Radar (ISAR) and ESM systems suites. To destroy targets, the S-3B Viking employs an impressive array of airborne weaponry. This provides the fleet with a very effective airborne capability to combat the significant threat presented by modern combatants and submarines. Additionally, all S-3B aircraft are capable of carrying an inflight refueling "buddy" store. This allows the transfer of fuel from the Viking aircraft to other Naval strike aircraft, thus extending their combat radius.
