Re: Sikorsky S-61. SH-3
Sikorsky was quick to develop a commercial model of the Sea King.
The S-61L first flew on 2 November 1961, and was 4 ft 3in (1.27m) longer than the HSS-2 in order to carry a substantial payload of freight or passengers.
Initial production S-61Ls were powered by two 1350shp (1005 kW) GE CT58-140 turboshafts, the civil version of the T58.
The S-61L features a modified landing gear without float stabilisers.

On 7 August 1962, the S-61N made its first flight.

Otherwise identical to the S-61L, this version is optimized for overwater operations, particularly oil rig support, by retaining the SH-3's floats.
Both the S-61L and S-61N were subsequently updated to Mk II standard with improvements including more powerful CT58-110 engines giving better hot and high performance, vibration damping and other detail refinements.
