Three Ba.88s were modified by the Agusta plant in late 1942 to serve as ground-attack aircraft. The Ba.88M had the wingspan increased by 2 meters (6 ft 6½ in) to alleviate wing-loading problems, and featured dive brakes, Fiat A.74 RC.38 engines, and a nose armament increased to four 12.7 mm (0.5 in) Breda-SAFAT machine guns. Evaluated at Guidonia, they were delivered to the 103° Gruppo Autonomo Tuffatori at Lonate Pozzolo on 7 September 1943, the day before Italian Armistice.
