If fictional is OK, then have something from a setting that I'm working on. ;)
MBT-01A7X, which is the first to put an automated turret on the tank series.
The original MBT-01A7 tank, the last tank with an unautomated turret in Sol.
The MBT-01A8, the last tank in the SolForce arsenal that is armed with an ETC cannon...
The MBT-01A9, the first serial production tank in Sol with an electromotive weapon as its main armament.
The MBT-01A9M, the last of the MBT-01s and only recently coming out in-setting. ;)
(Thank Schwarzweiler for these)
The MBT-01 'General Williams' series of MBTs is one of the oldest MBT designs still in use in the solar system. Designed soon after the creation of SolForce as replacement part shipments were cut off, the MBT-01 was designed by the then newly-formed Solforce White Section wholely in-house but based off of the numerous designs that SolForce used up to that point.
Using a hybrid
/torsion bar suspension, the MBT-01 series has consistently kept its cross-terrain ability throughout the centuries. With a top speed of 80km/h on-road and 50km/h off-road, it is quite a speedy tank for its weight.
Its primary armor is -oddly enough, similar to the concepts brought about by the fictional setting Battletech, although in hindsight this isn't exactly surprising as what was essentially EndoSteel was first revealed to the world in the 2010s. The armor is a composite of various materials including conventional and unconventional alloys, metal foams, composites, metallic and nonmetallic ceramics, and carbon nanotubes with a weave of electro-reactive armor and various materials. This allows the MBT-01 series to withstand numerous weapon impacts while retaining effectiveness. Now, unlike its fictional counterpart, it doesn't make anyone wearing it invulnerable to penetrations (or close to it depending on the rules you use), it simply makes penetrations (especially when double-digit megajoule energies or greater are being thrown around) uncommon. The thicker the plate, the more uncommon these penetrations are. The front of the MBT-01 series is one of the few that goes with the Battletech stereotype due to how thick the frontal plate is (250mm).
The active protection systems are also a key component to the MBT-01's lifespan on the battlefield. Consisting of a suite of electronic warfare equipment (requiring an electronic warfare officer (EWO)) and an active protection system suite. While systems like TROPHY were used, newer models utilize the 'HardKill' 2cm pulse laser CWIS units. While the electronic warfare suite would degrade ATGMs, the active protection system shoots them down alongside any recoilless rifle rounds or RPGs. The RWS mount with the 15.5mm HMG can do ADS in a pinch, but it isn't recommended.
The armament of the MBT-01 series has changed over the centuries, with the current models utilizing a 65mm coilgun instead of an Electrothermal Chemical cannon. Outside of the MBT-01 to MBT-01A2, the entire series uses an iridium-alloy dart instead of a depleted uranium or tungsten carbide dart as its armor-piercing round. Each round has a muzzle velocity of 2km/s as standard, giving the projectile kinetic energy measured in the double-digit megajoules. In eras previous, this would simply rip any tank apart. The coaxial is a 15.5mm or 15.5mm ETC-FLARE HMG, capable of unleashing rounds with 100kj of kinetic force onto any target. The RWS mount is configurable to use a 15.5mm HMG or a 60mm AGL system. All of these (and the ADS) is controlled by VGI (Virtual General Intelligence) fire control systems that utilize the extensive sensor suite that the tank has.
It has a crew of four (a driver, a gunner, an EWO, and a commander).
