Ro.45
The last of the classic biplanes made by IMAM was this machine, an enhanced Ro.37. It was 10.37 m length, with a 12.32 m wingspan. First flight was on 10 December 1935.
The 820 hp Isotta-Fraschini Asso XI.RC40 engine boosted maximum speed to 350 km/h, ceiling to 8,000 m, and endurance to 2,250 km. Destined for long-range reconnaissance and light bombing, it remained a single prototype for unknown reasons: perhaps it was rated too costly or the improvements over the Ro.37 were not enough.
