Imam Ro.57 bis

The I.M.A.M. Ro.57bis was an Italian single-seat, twin-engine dive bomber used by the Regia Aeronautica in 1943 during WWII. Developed from a 1939 fighter prototype, about 50–60 units were produced and used for ground attack and anti-ship missions in Sicily, but they were considered obsolete and largely ineffective against Allied forces. 
 
Key Details of the Ro.57bis:
Role: Primarily a ground-attack aircraft and dive bomber.
Armament: The standard version featured two 12.7 mm Breda-SAFAT machine guns in the nose (later upgraded in some to include 20 mm cannons) and a centerline crutch for bombs up to  1,100lb, or in some cases up to  2,205lb.
Performance: Powered by two Fiat A.74 radial engines, the Ro.57bis had a maximum speed of roughly 284mph, which was insufficient for 1943 combat conditions.
Service History: It entered service with the 97° Gruppo in early 1943, but many were destroyed during Allied bombing raids on Italian airfields.
Structure: It featured a robust welded steel tube frame, designed for fast production, but was considered slow and poorly armed compared to contemporary twin-engine fighters.
