It made its maiden flight in August 1935, powered by a 720 hp (537 kW) Hispano-Suiza 9Vbrs radial engine. With this engine it reached a speed of 352 km/h (219 mph). In October that year it was re-engined with a 680 hp (507 kW) Hispano-Suiza 14Hbrs radial in a

engine. These aircraft were to be assembled in secret by the Belgium company LACEBA (Les Ateliers de Construction et d'Exploitation de Brevets Aéronautiques). Flight testing in Belgium was carried out with a 280 hp (209 kW) Salmson 9ABa engine, to give the impression that the aircraft was a trainer rather than a fighter, with the more powerful engine to be fitted when the aircraft was delivered to Spain. A second landplane fighter derivative was designed and built for the Spanish Republicans, the Romano R.92. This was powered by a Hispano-Suiza 12Ycrs engine as tested in the Romano R.90, and reverted to the gulled upper wing of the floatplane. A single example was built in 1938.


Operational history

The first six R.83s were delivered to Barcelona between April and July 1938. The six R.83s were re-engined with the intended Wasp-Junior engines and were probably used as advanced trainers.Nash, David

The remaining 18 R.83s had not been completed by the time the Spanish Civil War ended in April 1939. The sole R.92 was also delivered to Spain in 1938, but any use is unknown.
