The EKW C-35 was a 1930s Swiss two-seat reconnaissance biplane aircraft built by the Swiss Federal Construction Works (Eidgenoessische Konstruktionswerkstaette, K+W), Thun.

Development[edit]

Two aircraft were designed by the Eidgenössische Konstruktions Werkstätte to replace the Fokker C.Ve which the Swiss Air Force were using. The two projects were the EKW C-35 biplane and the EKW C-36 monoplane. After evaluation the air force ordered 40 C-35s in 1936. Additional aircraft were built from spares. The C-35 was a two-seat biplane with fixed tailwheel landing gear and conventional tail unit. The aircraft was powered by a Hispano-Suiza HS-77 V-12 piston engine (licence-built Hispano-Suiza 12Ycrs).

Operational history[edit]

The first aircraft was delivered to the Swiss Air Force in May 1937, and all had been delivered by the end of 1938. To supplement the aircraft in-service a further eight aircraft were built between 1941 and 1942 from spares. The aircraft were removed from front-line service in 1943 when replaced by the F&W C-3603 and transferred to night-flying units. The aircraft was withdrawn from service in 1954.
