The AMX-45 is a joint-Sieuxerrian/Gothic main battle tank produced by GIAT Industries and Gothic Tractory Factory. The tank was a result of the unification of the Gothic Lince main battle tank and the Sieuxerrian [[Wikipedia:AMX-40|]] projects. Both tanks were designed for the export market, however a memorandum of understanding was signed in 1985 which combined the projects as to avoid Sieuxerr and Gothia competing against each other. The hull and automotive components would be mostly Gothic in origin, with the turret and much of its advanced fire control systems being Sieuxerrian. The tank, along with their precursor projections, would be foundations for later advanced Entente main battle tank designs.

Development

Development of the AMX-45 began after the lackluster trial performance of the AMX-30 in the 1960s, citing automotive and protection inefficiencies.

Armament

Primary

CN-CR105 M.68

The initial M.74 model used the CN-CR105 M.68 105mm smoothbore tank gun. The CR105 fired a series of 105mm rounds with a focus on high-performance armor-piercing fin-stabilized discarding sabot (APFSDS) rounds. Testing with the ARE M.66 and later M.69 showed that the original understanding from the 1950s that new and rapidly developing HEAT ammunition would be near-impossible to armor against was untrue, and that HEAT was easier to resist than kinetic energy penetrators like APFSDS ammo.

The smoothbore nature of the CR105 M.68 allowed for more accurate and better penetrative performance of AP ammunition. The rounds retained effective accuracy and penetrative qualities out to over 3,000 meters. By the late 1970s however Sieuxerrian military intellgence became aware of the start of a new Ostlandic main battle tank project, known as Future Ostlandic Tank, or in Merovingian, Futur char ostlandique (FCO). The hypothesized FCO tank was considered to be near-immune to all existing and still-in-development 105mm ammo from the frontal aspect at and beyond 1,000 meters. Development of a new gun had been already underway, however this accelerated development as well as replacement of the 105mm gun on all M.74s.

Ammo for the 105mm gun would still be developed however, with the last round, the OFL-105 AC M.5UA, being accepted for use in the mid-1990. The round was able to penetrate some 520mm of RHA at a range of 2km.

CN-CR120 M.82

Influenced by the larger guns used by heavy tanks from the 1940s and 1950s, a program to eventually upgun the ARE M.74 from a 105mm to a 120mm had been underway not too long after the tank entered service. A number of different gun types were tested, including a 142mm gun-launcher, however these tested guns didn’t not pan out.

By 1982 the new gun, CN-CR120 M.82, had been accepted for use in the new turret for the ARE M.74B. The new 120mm gun provided ample penetration at combat distance over 2km against most tank threats.

Secondary

AA-MAS M.57

Mounted to the commander’s cupola is an AA M.57 machine gun. The machine gun is designed to be fired under-armor by the commander and can be employed against infantry and rotor-wing aircraft. The machine gun has 2,080 rounds in a magazine that extends around the rear of the commander’s cupola.

CN-MIT20 M.53

Coaxially mounted is a M.53 20mm autocannon. The coax is able to be elevated independently of the main gun, and can be elevated higher than the main gun. The primary use for the 20mm is for use against light ground vehicles, infantry and rotor-wing aircraft in lieu of the main gun. The 20mm autocannon is supplied with 600-rounds of ammunition.
