Armstrong Siddeley Python

The Armstrong-Siddeley Python was an early turboprop engine designed and built by the British Armstrong-Siddeley company.

Its main use was in the Westland Wyvern carrier-based heavy fighter, the turboprop engine replacing the Wyvern protoype's original Rolls-Royce Eagle 22 piston engine. In this application, the Python was rated at 4,110 EHP.

The Python, like other Armstrong-Siddeley's gas turbine engine designs, was named after a variety of snake.
