After entering the civil aviation market, in the early part of the 1920s, Breda envisaged its first military aircraft design, the A.3.

biplane bomber, utilizing the sesquiplane configuration, also featuring a biplane tail and four engines arranged in tandem nacelles.

Early test flights with the SPA 6A engines showed very modest performance, so it was decided to replace the four SPA 6As with two Lorraine 12Db V-12 engines, each yielding 298 kW (400 hp).

However, this modification failed to translate into much better performance, and development of the A.3 was halted.
