Could be because it one of the few yank machines we bought and actually made better when we built them. (Especially with the gnomes).
Before Westland was licensed to build the S-58, Sikorsky had already built the HSS-1 which had two T-58s driving into a combining gearbox. I believe Sikorsky did this on their own hook but the US Navy was not too interested. Perchance Westland copied the design but with British engines?
