The Challenger 2 Life Extension Project (LEP) is a British MoD contract to remove obsolescence from Challenger 2 and extend its out-of-service date by ten years to 2035. As well as removing obsolescence, there will be the opportunity to make further capability enhancements. The upgraded tank will be referred to as Challenger 2 Mark 2. The prototype was displayed at DVD 2018, painted in black to justify its nickname: “Black Knight”.
