English: Pictured is the new AJAX prototype shown near its future assembly site in Merthyr Tydfil, Wales.AJAX provides a step-change in the Armoured Fighting Vehicle capability being delivered to the British Army.The programme includes six variants: AJAX, ARES, APOLLO, ATHENA, ATLAS and ARGUS. Each AJAX variant will be an agile, tracked, medium-weight armoured fighting vehicle, providing British troops with state-of-the-art best-in-class protection.The vehicles are developed upon an adaptable and capable Common Base Platform, maximising commonality in mobility, electronic architecture and survivability that ensures the British Army has a family of world-class platforms.Each AJAX platform variant has extensive capabilities, including acoustic detectors, a laser warning system, a local situational awareness system, an electronic countermeasure system, a route marking system, an advanced electronic architecture and a high performance power pack.The AJAX family of vehicles has growth built in. With an upper design limit of 42 tonnes of driveline capability, scalable and open electronic architecture and a modular armour system, it has enormous potential to combat future threats and incorporate new technology throughout the lifespan of the platform.As a result, AJAX provides the kind of growth capability that the user will need to face the uncertain challenges of Future Force 2020 and beyond. AJAX will replace the less capable CVR(T), providing broad utility throughout the balanced Army 2020 force across all operations.The AJAX programme was originally known as the SCOUT Specialist Vehicle (SV) programme. It was renamed at DSEI (Defence Systems&Equipment International) exhibition on 15 September 2015.Ultimately there will be 589 SCOUT SV platforms supplied to the British Army.
