Focke-Wulf Fw-190D

The Focke-Wulf Fw 190D ("Dora") was used by the Luftwaffe as a high-altitude interceptor and fighter-bomber from September 1944 through the end of World War II, primarily on the Western Front against Allied bombers. Known for superior performance over earlier models, it was heavily used to defend Germany and in major operations like Operation Bodenplatte. 
Key details regarding the usage of the Fw 190D include:
 
Operational Role: Served as an elite interceptor, often used to protect Messerschmitt Bf 109s and other FW 190s against Allied aircraft.
Primary Fronts: Primarily operated in the European theatre during the final year of the war.
Key Units: Often assigned to elite units like JG 3 "Udet".
Distinguishing Feature: Known for replacing the radial engine of earlier Fw 190s with a Junkers Jumo 213 inline engine to improve high-altitude performance. 
 
The Fw 190D was considered one of the best piston-engined fighters in the Luftwaffe.
