Armored Systems Modernization

The Armored Systems Modernization (ASM) was a U.S. Army combat vehicle procurement program canceled in 1992. The Army sought to develop a family of six armored vehicles based on two common chassis, one heavy and one medium, which would both share commonalities. Systems that the ASM sought to replace included the M1 Abrams main battle tank, M109 howitzer and M2 Bradley infantry fighting vehicle. The Army spun out several of the systems—Advanced Field Artillery System, Line-of-Sight Anti-Tank and the Armored Gun System—after canceling the program, but all of these programs were eventually canceled.
