The IMAM Ro.57 was a heavy-fighter that was used by Italy during World War II.
The IMAM Ro.57 used two Fiat A.74 RC 38 engines that were capable of propelling it at speeds of up to 501 km/h. The Ro.57 had good performance, however its armament was severely underpowered for its role of heavy-fighter. Two 12.7mm Breda SAFAT machine guns were simply too weak to take on most mid-war aircraft of the Second World War.
To correct the issue of armament, the Ro.57bis was developed as a dive bomber/heavy fighter. It was fitted with two additional 20mm autocannons and a single 500 kg bomb along with dive brakes. However, the problem was that the added weight affect performance, slowing down the aircraft's top speed to only 457 km/h.
