IMAM (Industrie Meccaniche e Aeronautiche Meridionali) was an Italian aircraft manufacturer founded in Naples in 1923 by the engineer Nicola Romeo.
[1] In addition to their use aboard ships, a few Ro.43's (average strength, four floatplanes) were employed by the 161ª Squadriglia Caccia Marina of the Aeronautica dell'Egeo as fighter protection for the Italian-held islands in the Aegean Sea.
Designed by Giovanni Galasso, the IMAM Ro.57 began to leave the production lines of the Naples factory early in 1942, and entered service in small numbers with the Regia Aeronautica as a fighter-bomber because of its comparatively low speed and poor manoeuvrability.
[5] Carrying up to a 500 kg (1,102 lb) bomb under its fuselage, this version was fairly successful but had faded from the scene before the Armistice of Cassibile.
[6] The Ro.63, a short-range reconnaissance and light transport aircraft of comparable quality and reliability or even superior to its German competitor, the Fieseler Fi 156 Storch, was not put into production in significant numbers due to the shortage of available engines.
After World War II Officine di Pomigliano per le Costruzioni Aeronautiche e Ferroviarie-Aerfer was constituted and in 1955 merged with IMAM to form Aerfer.
