The XM104 self-propelled howitzer, pilot No. 3, was tested to determine the readiness of the weapon system for engineering and user tests. The automotive program consisted of amphibious operations and 4000 miles of endurance testing. Amphibious capabilities are limited by low draw bar pull and by maneuverability which is influenced by wind effects on the canvas enclosure carbon monoxide concentrations are also a potential hazard. Track life is unsatisfactory and component service life and maintenance are adversely influenced by vehicle vibration. It is recommended that the vehicle undergo engineering and user tests after the appropriate modifications are made in the problem areas revealed during this test.
