Hurricane in Combat - Mk I - Mk II - Mk III - Mk IV - Mk V - Mk X-XII
The prototype of the Hurricane Mk IV had been equipped with the Merlin 32 engine, capable of providing 1,700 hp. The final production version had used the slightly less powerful Merlin 24 and 27, each of which gave 1,620 hp. In 1943 two Mk IVs were converted to use the Merlin 32, and re-designated as Mark Vs. The Mark V first flew on 3 April 1943. It reached a maximum speed of 326 mph, but overall performance was not significantly improved, and the Merlin 32 engine tended to overheat. The project was abandoned, and the two aircraft converted back to the Mk IV standard.
