The proposed Fw 300 had an all-metal airframe, a low-wing cantilever configuration, and a pressurized fuselage, possessing a smoothly contoured forward fuselage and nose, somewhat reminiscent of the Boeing 307 Stratoliner airliner in shape. Space was provided for up to 50 passengers in individual compartments. The landing gear was retractable. Four wing-mounted piston engines were proposed to drive the aircraft. Two engine candidates were:

• The highly experimental Junkers Jumo 222, a 24-cylinder "multibank" inline engine (six inline banks of four cylinders each, arranged at 60° intervals around the crankcase), rated at 1,864 kW (2,500 hp), which in the event never proceeded to the production stage during the course of the war with just under 300 examples built in several different versions;
• The Daimler-Benz DB 603, a 12-cylinder inverted-V engine rated at 1,342 kW (1,800 hp) and the largest displacement inverted-V12 aviation powerplant built by Germany in World War II.

Both engines were liquid-cooled.

In the proposed military configuration, the eight-man crew was to have been enclosed in one pressure cabin, and the defensive gun armament operated remotely. For anti-ship missions, it would have carried guided missiles.

Design work continued during the first years of the war, but was shelved as the need for long-range bombers or other long-range efforts diminished and other priorities emerged. Construction of a prototype was never started.
