Finnish Air Force
The Aero A.11 was a biplane light bomber and reconnaissance aircraft built in Czechoslovakia between the First and Second World Wars. It formed the basis for many other Czechoslovakian military aircraft of the inter-war period. Around 250 were built, with some remaining in service at the outbreak of World War II.
Designed by Antonin Husnik, it was a development of the Aero A.12 (despite what the numbering of the designs might suggest). A Hispano-Suiza 8Fb-powered version, the A.11H-s was built for the Finnish Air Force, the only foreign operator of the type. The Finns had eight aircraft of this type and used them between 1927-39.
- A.11 : Two-seat light bomber, reconnaissance biplane.
