Aero Ae 03

The Aero Ae 03 was a prototype Czechoslovakian military reconnaissance aircraft aircraft designed in 1921. It was an ambitious monoplane design, and was completely original to Aero, unlike the firm's licence-built designs from World War I. It was to be equipped with an early turbocharger.

As work progressed, it became clear that the finished product was not going to meet the requirements of the Czech Air Force specifications that it was developed to meet. Specifically, the aircraft was going to be too heavy, and with redesign judged to be impractical, construction was halted before the aircraft ever flew.
