The Baldwin Locomotive Works was charged with modifying the M3 hulls to fit the T40 design standard and this work began in 1941. Some 1,000 of the type were on order by the American Army following the Japanese attack on Pearl Harbor in December of 1941. Despite the work ongoing through much of the early part of 1942, the program was cancelled during August due to the limited stock of 3" guns on hand as well as the shifted in focus to the promising M10 "Wolverine" tank destroyer. This left the T40/M9 project to the pages of history and nothing more.
The M10 would go on to become a classic American wartime fighting vehicle with over 6,700 produced from 1942 to 1943.
