The Westminster extended the Westland design organisation even further in
an attempt to produce a large single rotor transport helicopter. The project
was based upon a research vehicle, wholly funded by Westland using the Sikorsky
S-56 rotor and transmission system, powered by two large Eland gas turbines.
Two prototypes were produced, the first being a dedicated research airframe with a simple tubular steel structure, the second prototype was fully representative aerodynamically intended to lead to a production standard.
However, indications were that official support could not be guaranteed and further work did not proceed beyond the research phase.
