Breda Ba.27 was an Italian single-seat biplane fighter developed in the early 1930s by Società Italiana Ernesto Breda for evaluation by the Regia Aeronautica and export trials. Designed during a period of rapid aviation innovation alongside contemporaries such as the Fiat CR.30 and Hawker Fury, the Ba.27 reflected interwar design trends and the influence of foreign engines and airframe practices. Although it failed to enter large-scale production, the type contributed to Italian aeronautical experience that informed later fighters like the Fiat G.50.
The Ba.27 emerged from design activity at Breda during a period when companies including Fiat, Caproni, Macchi, and Savoia-Marchetti were responding to procurement competitions held by the Regia Aeronautica and comparable services such as the French Armée de l'Air and the Royal Air Force. Drawing on structural practices seen in designs by Hawker Aircraft and Gloster, the Ba.27 combined a welded steel tube fuselage with wooden wing structures similar to those used by Bristol and Armstrong Whitworth. Prototype flights were conducted at facilities near Milan and the Breda works, and testing involved pilots associated with the Accademia Aeronautica and Regia Aeronautica evaluation squadrons. During evaluation, comparisons were made with prototypes like the Fiat CR.30, Ansaldo A.300, and Reggiane types, influencing Breda's approach to aerodynamics and pilot ergonomics.
The Ba.27 featured a single-bay biplane layout with staggered unequal-span wings, using N-type interplane struts influenced by designs from Handley Page and Fairey. The fuselage incorporated welded tubular steel similar to methods practiced at Piaggio and Savoia, while control surfaces employed conventional cable-and-pulley systems like those seen on Morane-Saulnier and Dewoitine types. Powerplants trialed included the Bristol Jupiter and Alfa Romeo radial engines, reflecting licensing and procurement links between Italian firms and Bristol Aeroplane Company and Fiat. Armament provisions mirrored contemporaries such as the Hawker Fury, offering synchronized Vickers-style machine guns and options for Breda-manufactured guns. Landing gear was fixed with trouser-style fairings, following patterns used by Avro and PWS, and instrumentation catered to pilots trained at the Reparto Sperimentale and Scuola di Volo.
After flight testing, a small batch of prototypes and pre-production airframes were allocated to Regia Aeronautica units for evaluation, alongside competing types from Fiat, Macchi, and Breda's rivals. Service trials involved units based at airfields in Sardinia and Sicily, and exercises coordinated with naval units such as Regia Marina assets for coastal patrol comparisons similar to exercises that involved CANT and Savoia-Marchetti seaplanes. The Ba.27 did not see combat deployment on the scale of later fighters in the Spanish Civil War, where aircraft like the Fiat CR.32 and Heinkel He 51 operated, and the type was phased out as the Regia Aeronautica adopted monoplanes and more powerful engines like those found in the Fiat A.74 and Piaggio P.XI. Export prospects to countries such as Hungary, Romania, and Paraguay were explored but disappointed due to rapid advances in designs from Messerschmitt, Polikarpov, and Boeing.
Several variants and experimental modifications were attempted during the Ba.27 program. Proposals included engine swaps to accommodate powerplants from Alfa Romeo and Bristol, structural revisions inspired by Curtiss and Gloster practices, and trials with alternate armament mounts similar to those used on Dornier and Junkers fighters. Some airframes were used as testbeds by Breda and associated engineering teams collaborating with companies such as OM, Caproni, and Fiat to evaluate materials and manufacturing techniques that later influenced projects like the Breda Ba.65 and other Breda designs.
- Regia Aeronautica - Breda works test squadrons and Reparto Sperimentale personnel participated in evaluation flights. - Proposed but unrealized customers included air arms of Romania, Hungary, and Paraguay, which instead procured types from manufacturers such as Hawker, PZL, and Fokker.
No complete Ba.27 airframe is known to survive in museum collections such as Museo Storico Aeronautica Militare, Museo Nazionale della Scienza e della Tecnologia Leonardo da Vinci, or other European aviation museums that house examples from Breda, Fiat, Caproni, and Macchi. The Ba.27's principal legacy lies in its contribution to Italian design practice and industrial collaboration networks linking Breda with Alfa Romeo, Fiat, and Bristol, and in the experience gained by pilots and engineers who later worked on significant types including the Fiat CR.32, Breda Ba.65, and Macchi C.200. The program also informed procurement lessons relevant to the Regia Aeronautica as it transitioned to monoplanes and engaged with international suppliers such as Messerschmitt, Polikarpov, and Boeing.
