Aero Ae-02
The Aero Ae 02 was the first fighter aircraft to be designed and built in Czechoslovakia, first flying in 1920. Designed by Husnik and Vlasak, it was of conventional biplane configuration. The aircraft's performance was adequate for a fighter of its day, but the Czechoslovak Air Force was not interested in purchasing it. Development continued as the Ae 04.
Aero A-11
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 a large number of 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.
Aero A-30
The Aero A.30 was a biplane light bomber and reconnaissance aircraft built in Czechoslovakia in the late 1920s. It originated as an attempt to improve the performance of the Aero A.11, but soon evolved into quite a different aircraft, larger and more powerful than its predecessor. The aircraft is readily distinguished from other related types by the difference in spans between its wings - the upper set being of much greater span than the lower. Prototypes of the A.30 were retrospectively designated A.130, with the A.230 the main production version. The A.330 and A.430 featured different, more powerful engines, but the latter of these did not enter production, serving instead as the prototype for the Aero A.100.
Aero A-32
The Aero A.32 was a biplane built in Czechoslovakia in the late 1920s for army co-operation duties including reconnaissance and tactical bombing. While the design took the Aero A.11 as its starting point (and was originally designated A.11J), the aircraft incorporated significant changes to make it suited for its new low-level role.
Like the A.11 before it, the A.32 provided Aero with an export customer in the Finnish Air Force, which purchased 16 aircraft in 1929 as the A.32IF and A.32GR (which spent most of their service lives as trainers). They were assigned numbers AEj-49 - AEj-64 and were used until 1944. At least one fuselage has survived, preserved at the Finnish Air Force Museum (in storage as of 2003).
A total of 116 of all variants were built.
