U.S. XM2001 Crusader 155mm Self-Propelled Howitzer

U.S. XM2001 Crusader 155mm Self-Propelled Howitzer. . Development of the Crusader began in the 1980s as a replacement self-propelled artillery system to the M109 series, 155mm self-propelled howitzers. The program requirements drove significant enhancements in the areas of mobility, lethality and survivability. It was originally planned to use a new liquid propellant. However, in 1996 this requirement was changed to the more familiar solid propellant. This, as well as numerous other changes coupled with the requirement to reduce its maximum weight from 61 to 41 tons, slowed development of the program. Crusader was fully automated, requiring a crew of only three, yet, still capable of firing 8 rounds to strike a single target at one time. Along with Crusader, a new ammunition vehicle was developed capable of resupplying Crusader's 48 rounds of ammunition and re-fuel it automatically. The first prototype Crusader was delivered in early 2000 and was tested at Yuma Proving Ground, Arizona. First production was planned for 2006 with Crusader to enter service in 2008.
