Caudron C.21
Development and Specifications
The twin-engine biplane Caudron C.21 appeared in November 1917. Initially, it was equipped with 80 hp (60 kW) Rhone rotary engines, but these were later replaced by more powerful 120 hp (90 kW) engines.
Wartime Non-Deployment
Aircraft of this type were never used during World War I. However, for post-war commercial use, they were redesigned, resulting in the C.21bis modification.
Post-War Reconfiguration and Flights
Immediately after the war, the C.21 itself undertook a series of ‘pioneering’ flights, showcasing its potential beyond initial military applications.
