The C5A program began in the fall of 2017, about a year and a half into the war. Incorporating lessons in tank design from their previous efforts, the engineers at Union Defense Systems were able to create a powerful main battle tank, one that is more than a match for any tank threat that the Russian Coalition may throw at it.
Design- The design of the C5A is a composite of the great trio of western Main battle tanks, the Abrams, Leopard 2, and the Challenger 2. The best aspects of each vehicle were carefully selected, and then upgraded thoroughly. Most importantly however, was the Rheinmetall 140mm tank gun, its main asset. The design is fairly conventional, with the standard 7 roadwheel design of most Western tanks. The vehicle has a crew of three, a driver, gunner and commander.
Defense- The C5A is the most survivable MBT in the world due to a new armor trio- Explosive Reactive Armor, Composite Armor, and Active Protection Systems. The "Arctic Wolf" contains the latest "Vigilant Watch" Explosive Reactive armor, deflecting all but the largest of shells. In order to even reach the Vigilant Watch, it must pass through the UFS standard Guardian Active Protection suite, the same kind used on the M113A5, which has a projectile intercept rate of 97.24%. 12 Anti-projectile Missiles are carried, but they can be restocked quickly. The last part of this armor system is Generation 3 Chobham armor. When fused together this tank is hard enough to hit, let alone disable or destroy.
Armament- The main armament of the C5A is the Rheinmetall 140mm tank gun, capable of penetrating all known armor threats up to 4 km away. The ammunition type is also highly advanced, and the APFSDS ammunition is considered the second best in the world (only behind US munitions). It contains the usual Predator 12.7mm HMG and missle combination, which is useful for destroying flanking armor, so the tank does not have to move its turret. It also has a coaxial 7.62mm MG underneath the turret. A highly advanced optical system allows for performance in day and night that is paralleled only by the M1A3 and Leopard 2A7.
Propulsion- The Technicians at Hadron Works decided to refine their previous engines and started working on the HW-H/E552P engine, easily matching the power of diesel engines while being 70% quieter and about 64% more fuel effiecient. The tank can run for 3 hours without gas, but with a decrease in performance. Top speed is an estimated 80 km/h on roads or very flat or downhill terrain.
