OF-40

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 developed and produced the hulls, and automotive components were provided by Fiat (the designation of the vehicle comes from the initials of the two companies, whereas "40" refers to the mass of the tank). Initial design work was started by OTO Melara in 1977, with the first prototypes ready by 1980.

Variants

 * OF-40 Mk.2: The Mk.2 version of the OF-40 featured an improved OG14LR fire control system which included dual-axis main gun stabilisation and improved sensors. The Mk.2 had an improved day/night periscope for the commander, an improved sight with variable 7x and 14x magnification for the gunner, and a turret-mounted LLLTV camera which provides night-time observation and identification up to 2 km and relays imagery to monitors at both the gunner's and commander's stations. This variant also received welded steel appliqué armour on the turret front face. All Ethiopian and UAE OF-40s have been upgraded to Mk.2 standard.
 * OF-40 ARV: An armoured recovery vehicle based on the OF-40 chassis, manned by a 4-man crew and equipped with an 18-ton crane, a 35-ton winch, dozer blade and a welding kit.
 * OF-40 SPAAG: Although it was never produced, a self-propelled anti-aircraft vehicle similar to the Gepard was proposed should any customers request it.
