De Havilland Mosquito PR Mk IX

The Mosquito B Mk IX saw a change of engine to the 1,680 hp Merlin 72 engines with two stage superchargers that allowed them to produce 1,505 hp at 21,000 feet. The new engines gave the Mk IX a top speed some 50mph faster than the earlier B Mk IV.

Of the total of 144 Mk IXs produced, 90 became PR Mk IXs. With a full internal fuel load, two 50 gallon drop tanks and a 100 gallon tank under each wing, this aircraft could carry over 1,000 gallons of fuel, giving it a range of 2,450 miles at 250mph. The PR Mk IX entered service with No. 540 Squadron in April 1943, and remained in service for the rest of the war.
