Black Night is a technology demonstrator for BAE Systems' proposal for the Challenger 2 life extension project LEP . The Black Night has several new enhancements, mainly around the turret, including a Safran Paseo commander's independent sight, a Leonardo thermal imager for the gunner, and a Leonardo night sight DNVS 4 to provide hunter-killer capabilities thanks to thermal imaging equipment for the gunner, commander, and driver. Other additions included a laser warning system and the IMI Iron First hard-kill active protection system.
