The DOFLUG D-3803 was a Swiss fighter aircraft developed from the D-3802 program in 1942, which had its origins in a collaboration with France before World War II. It was based on the Morane-Saulnier MS.406, known locally as "D-3800." The D-3803 retained some features from the D-3802, like the single-seat cockpit and retractable landing gear, but it also had improvements, including a better canopy for improved visibility and a shorter back fuselage. The engine was changed to a locally licensed 1,430 hp liquid-cooled Saurer YS-3 inline-piston engine.
Armed with three 20mm Hispano-Suiza HS-404 automatic cannons, the D-3803 could also perform fighter-bomber missions with bombs and missiles. Despite its modern appearance and impressive potential with speeds of up to 423 miles per hour and high altitudes, the D-3803 faced setbacks. World War II ended before the prototype could fly, and engine problems during testing delayed the project further. Eventually, the Swiss Air Force opted to acquire the North American P-51D Mustang from the United States, leading to the abandonment of the D-3803.
In summary, the DOFLUG D-3803 was a Swiss fighter plane developed from the D-3802 program, based on the French Morane-Saulnier MS.406. It featured design improvements but faced delays due to the end of World War II and encountered engine issues during testing. Ultimately, the Swiss Air Force chose a different fighter aircraft, the P-51D Mustang, instead of pursuing the D-3803.
