The Focke Wulf was the only 4 engine plane used by the German Air Force during World War II. It was a good plane, but it had its limitations and was certainly not a match to the heavy long range bombers of the US Air force.
The FW 200 also called the Condor first flew in 1937. It had a range of 3600 km and an endurance of 14 hours. Orginally it was supposed to be a air liner for carrying passangers, but once war broke out it was adapted to various uses as a bomber and a military transport.
The Condorwas designed by Dr Kurt Tank, who after the war worked in India at Hindustan Aeronautics and helped design the Marut. The Condor had some distinctions. it flew non stop from Europe to America across the Atlantic on 10 Aug 1938. It did the trip in 24 hours and a return trip in 19 hours. This established the air worthiness of the Condor and it was inducted into the Luftewaffe.
The Condor had a top speed of 360 km an hour and was used by the Germans as a recce plane in the Atlantic war.
The Condor was also used to supply troops in Russia, but the harsh weather conditions made the efforts of the Condor redundent. Hitler had one Condor done up as his personal transport plane, which was destroyed in an allied attack in 1944.
The Condor was powered by 4 BMW air cooled radial engines and could carry 36 troops or 30 passangers in comfort. It had a crew of 5 to operate and a service ceiling of 19700 ft.
The Condor brought out the limitations of the German aircraft industry and the failure to develop a 4 engine long range bomber proved the nemesis of the German Air force and contributed to the defeat of Germany. Presently only one refurbished Condor is available at the Technical Museum in Berlin.
