Tested in Dec 1944, Yakovlev Yak-9M production actually began 10 months prior in Feb 1944. With uprated engine and propeller its cockpit had to be moved rearward 400mm to compensate for the heavier nose section. In flight characteristics and armament the Yak-9M proved equal to the Yak-9D. 4239 Yak-9Ms were produced from May 1944 to June 1945.
