Chrysler built 9,002 steel pontoons for the Navy at its Jefferson Avenue plant at the foot of Conner Street, in Detroit, (still active today), where it also made its marine engines. They then combined the two product lines, building 8,229 "Sea Mules", which were powered and steerable pontoons. Finally, they built 1,038 tractor tugs for the Army.
