The US Army's Crusader field artillery system is a two-vehicle system that consists of a fully automated 155mm self-propelled howitzer and a resupply vehicle. Crusader can fire up to 12 rounds per minute and can travel at cross-country speeds of 48 kilometers per hour, highway speeds of 78 kilometers per hour, and dash speeds of 750 meters in 90 seconds. Crusader was conceived to replace the Paladin howitzer cannon.
