The OF-40 is an Italian main battle tank developed as a joint venture between OTO Melara and Fiat, and intended primarily for export sales. OTO Melara would develop and produce the hulls, and automotive components would be provided by Fiat (the designation of the vehicle comes from the initials of the two companies, whereas "40" refers to the planned mass of the tank).^[1] Initial design work was started by OTO Melara in 1977, with the first prototypes ready by 1980.
