The Armstrong-Siddeley automobiles (and later aircraft engines) were an English marque manufactured from 1919 (after the company was formed in 1917 by a merger between two Coventry_based companies, Armstrong-Whitworth and Siddeley-Deasy) to 1960. ...

Its main use was in the Westland Wyvern carrier-based heavy fighter, the turboprop engine replacing the Wyvern prototype's original Rolls-Royce Eagle 22 piston engine. In this application, the Python was rated at 4,110 EHP. The Westland W.34 Wyvern was a single-seat carrier-based attack aircraft of the 1950s intended to cover a wide variety of roles. ...
