The Sikorsky SH-3 Sea King (company designation S-61) is an American twin-engined anti-submarine warfare (ASW) helicopter designed and built by Sikorsky Aircraft.

The Sikorsky SH-3 Sea King is a twin-engine medium-sized amphibious rotorcraft. The powerplant used on the Sea King was the General Electric T58-GE-8B, which was initially capable of generating up to 1,250 shp (930 kW) each.

In normal operations, the Sea King typically would have a four-man crew on board; these being a pilot and copilot in the cockpit, and two aircrews stationed within the main cabin area.

ASW equipment used on Sea Kings has included the AQS-13A/B/E dipping sonar which included specialized computers for processing sonar and sonobuoy data, various models of sonobuoys, ARR-75 Sonobuoy Receivers, and the ASQ-81 Magnetic Anomaly Detector.
