it was fitted with a copy of a Daimler-Benz engine made by bristol for this project due to the shortage of the merlin. A supply of spare parts for the engines were not required as the operation live of this class of aircraft was measured in hours. ( The air ministry expected them to be operational for 24 hours were they actually lasted for 18 days)
