During the period of 198 1 ~ 1982, the US Army Engineering School in Fort Bevo, Virginia conducted a preliminary study on a new type of obstacle-crossing vehicle. Later, based on the chassis of American M88 armored rescue vehicle, Belfo R&D and Engineering Design Center designed the 1 test sample, which was manufactured by Bowen-Ma Kraulin-York Branch of Hasko Company in Pennsylvania. The first prototype started testing in June 1985, and the second prototype was sent to Israel for evaluation and testing. The success of the test laid the foundation for the US Army to determine the operational performance required for mass production of COV. Small batch production is expected to start at the end of 1990.
