Ajax is a family of armoured fighting vehicles developed by General Dynamics UK for the British Army, intended to replace the ageing Scimitar and CVR(T) reconnaissance fleet. Contracted in 2014 for 589 vehicles across six variants at roughly £5.5 billion, the programme's cost had grown to £6.3 billion by April 2026 with only 165 vehicles delivered, 28% of the order.
Ajax became the defining emblem of British defence procurement failure after trials from around 2019 surfaced abnormal noise and vibration that caused crew injuries, alongside malfunctioning sights and software instability that kept vehicles off-road for extended periods. General Dynamics and the Ministry of Defence spent years disputing responsibility, with deliveries originally due by 2017 still incomplete nearly a decade later.
The programme is now routinely cited in parliamentary debate and reviews of procurement culture, including Lord Robertson's Strategic Defence Review, as the clearest example of the gap between Britain's stated defence ambitions and its industrial and procurement capacity. Vehicles delivered to date are reported operational, but the overrun has consumed resources that could have expanded the fleet or funded other capabilities.
