History

Designed and built by the newly established Aero firm in Prague, the A.11 entered service around 1925 and was exported to several countries. It represented a refinement of earlier Aero biplane designs, incorporating lessons learned from the A.10 series. The type saw broad domestic use and modest export success in the late 1920s.

Variants

Several sub-variants were produced with different engines and equipment fits; the Aero A.11 family also spawned floatplane derivatives for coastal and riverine operations.

Where you'll see it

Served as the backbone of the early Czechoslovak Air Force during the late 1920s; also exported to Yugoslavia and other regional operators.
