EKW C-3603

The Eidgenoessische Konstruktionswerkstaette (EKW) C‑3603 was a Swiss-designed, all‑metal fighter‑bomber that entered service in 1942. Conceived as a response to the need for a domestically produced combat aircraft during the Second World War, the C‑3603 evolved from the earlier C‑3602 prototype and incorporated a powerful Hispano‑Suiza 12Y-51 V‑12 engine delivering 860 hp. Its low‑wing monoplane layout, retractable under‑carriage and a bubble canopy gave it a sleek silhouette and excellent visibility for the pilot. Armament typically comprised two 20 mm Oerlikon cannons and up to four 7.5 mm machine guns, while wing‑mounted hard points allowed the carriage of bombs or rockets, making the type versatile for ground‑attack missions. A total of 164 airframes were built, serving with the Swiss Air Force throughout the war and remaining in frontline service until the early 1950s. The C‑3603’s significance lies in demonstrating Switzerland’s capacity to design and produce a competitive fighter on its own, reinforcing national neutrality and self‑sufficiency. Its robust construction, reliable performance at high altitude, and adaptability made it a respected aircraft among contemporaries. Following its retirement, several examples were preserved in museums, and a handful were later fitted with modern avionics for civilian experimental flights, underscoring the type’s lasting engineering value.
