Lockheed S-3 Viking
The Lockheed S-3 Viking is the US Navy's carrier-based, fixed-wing ASW aircraft.

Designed to meet the US Navy's 1964 VSX (experimental carrier-based ASW aircraft) requirement, the first service-test YS-3A (of eight built) made its maiden flight on 21st January 1972 at Palmdale, CA.

Conventional in design for a carrier-based warplane, the Viking is a high-wing, twin-turbofan aircraft with hydraulically-folding wings, and pressurised accommodation for its crew of four )comprising pilot, co-pilot, tactical co-ordinator and acoustic sensor operator).
Based on an August 1969 contract, Lockheed manufactured the Viking in partnership with Vought, which designed and built wings, tail unit, landing gear and engine pods.

The original production S-3A variant is equipped with a Univac AN/AYK-10 digital computer, Texas Instruments AN/APS-116 radar and Texas Instruments OR-89 FLIR.
The heart of the aircraft's ASW suite is a Texas Instruments AN/ASQ-81 magnetic anomaly detector sensor housed in a retractable tail-boom.
The Viking carries 60 sonobouys in its aft fuselage and has a ventral bomb bay and wing ordnance stations able to house bombs, torpedoes or depth charges.
The first S-3A Viking went to VS-41 'Shamrocks', the first FRS for the type, located at North Island, CA, and was received in February 1974.
VS-21 'Fighting Redtails', also at North Island, became the first fleet squadron to operate the type in July 1974.
Lockheed built a total of 179 production S-3A's, delivering the last aircraft in August 1978.

The improved S-3B variant is the result of a weapons system improvement programme launched in 1981, which retains the Viking airframe and engines but adds improved acoustic processing, expanded ESM coverage, increased radar processing capabilities, a new sonobouy receiver system, and provision for AGM-84 Harpoon air-to-surface missiles.
All but identical in outward appearance to the S-3A, the S-3B can be distinguished by a small chaff dispenser on its aft fuselage.
Nearly all existing S-3A's have been upgraded to S-3B status at naval air depots.
Except for a few S-3A's scattered among the two training and two fleet air reconnaissance squadrons, the entire Viking force now consists of the upgraded S-3B model.

Cold War Operations Developed to meet the Cold War threat posed by the Soviet fleet of quiet, deep-diving nuclear submarines, the S-3 fought in Operation Desert Storm against an enemy which possessed no submarines.
The S-3A/B Viking proved an exceedingly effective conventional bomber when employed against Iraqi radar stations, anti-aircraft batteries, small vessels in the Persian Gulf and other targets.
On a typical mission on 20th February 1991, an S-3B of VS-32 'Maulers' operating from USS America (CV-66) employed its own inverse SAR and FLIR, plus guidance from the cruiser USS Valley Forge (CG-50), to despatch an Iraqi combat vessel with a stick of three Mk 82 500lb (227kg) bombs.
