The Challenger 4 Main Battle Tank took over from the Challenger 2 as the UK MOD's main battle tank in 2075AD. The Challenger 3 was developed in secret and implemented the new hover technology introduced in domestic transport. The Challenger 3 was never considered suitable for combat purposes and saw a complete make over which resulted in the Challenger 4.
Like its predecessors it carried many world leading technologies including Dorchester Level 5 armour, the lazed 150mm rifled gun and a BV (boiler vessel, after all the British do like there tea!)
Also like its predecessors the tank is manned by a crew of 4 (Commander, driver, gunner and signaller)
Its main and biggest development is the Perkins Hover HV-16MBT engine which saw the tracked tank into the history books giving the Hover tank increased manoeuvrability and speed.
