The only reason that the number of RAF tactical reconnaissance squadrons with Mustangs diminished to only one by the end of WWII was not because of any deficiency in the aircraft, but simply due to attrition of an aircraft that was no longer in production. The aircraft that replaced it (Typhoons and Spitfire fighters fitted with cameras) were not so good in that low-level role. The Allison Mustang still was one of the highest performing aircraft at low altitude right up to the end of the war, and besides its role in reconnaissance scored quite a number of victories as a fighter in the process.
