XM2001 Crusader Guide, Meaning , Facts, Information and Description

The XM2001 Crusader was to be the United States Army's next generation self-propelled howitzer, designed to provide significant increases in artillery survivability, lethality, mobility, and operational effectiveness. In early May 2002, United States Secretary of Defense Donald Rumsfeld cancelled the US$11 billion program due to it not being considered sufficiently mobile nor precise enough for modern requirements, although some military analysts dispute this.

The Crusader was intended to displace the M109A6 Paladin Self-Propelled Howitzer and the M992A2 Field Artillery Ammunition Supply Vehicle (FAASV). Crusader is a fully automated cannon artillery system to support the Initial Brigade Combat Teams (IBCT) Counterattack Corps and is a critical technology enabler for future systems.

In addition to strategic deployability (two howitzers transportable in the C-17 Globemaster), other key features of the Crusader included:

• the XM297E2 integral mid-wall cooled cannon that enables sustained high rates of fire;
• a reliable, fully automated ammunition handling and loading system designed to use the modular artillery charge system and automatic inductively set multi-option fuze;
• a state-of-the-art cockpit with embedded command and control that allows the crew to exploit the system's full battle capabilities;
• embedded training and diagnostics to facilitate skill retention and maintenance support;
• composite armor;
• a suite of survivability features to protect the soldier and the system; and
• the LV100-5 gas turbine engine (common with the Abrams tank) that provides the improved mobility to keep pace with the supported maneuver force.

RSVs enable automatic, reciprocal transfer of ammunition, data and fuel to the SPH or another RSV to maintain required firing rates and enable autonomous operations while capitalizing on the cost and operational advantages of common components. RSV critical technologies and capabilities include an automated docking boom, ammunition resupply system, fuel transfer system, improved mobility, and embedded training and diagnostics.
