The Hawker Hurricane Mk IV was the last major change to the Hurricane design, the various versions of the Mk II with modified modified wings to meet specialised uses resulted in maintenance and supply problems, it was decided to design a more standardised and universal model to be known as the Hawker Hurricane Mk IIE fighter, after the first 250 had been built it was deemed prudent to re-designate the aircraft the Hawker Hurricane Mk IV to further reduce confusion and errors when ordering spare parts.
The Hawker Hurricane Mk IV was powered by the Merlin 24 or 27 engines equipped with dust filters for desert work, delivering 1,620 hp, it had a new universal wing capable of being fitted with two bombs, four 40mm cannons or eight 60 pound RP-3 unguided rocket projectiles as required to replace the standard eight machine guns.
Many Hawker Hurricane Mk IV's were converted by retro fitting the more powerful Merlin 32 engine and a four-bladed propeller into Mark V's, indeed the majority of surviving Hawker Hurricane Mark V's are converted Hawker Hurricane Mk IV's.
Hawker Hurricane IV Armament:
- Four 20 mm Hispano Mk II cannon
