The M1064 mortar carrier is an American vehicle, consisting of the M121 mortar – a version of the M120 mortar – mounted on an M113 chassis.

The M1287 mortar carrier vehicle will replace the M1064 in U.S. Army service.

The design consists of the M298 cannon, M191 bipod, M9 baseplate, and the carrier adaptation kit.

With the use of an auxiliary M9 baseplate and extension feet for the M191 bipod, the M121 can be dismounted from the vehicle and emplaced for ground-mounted operations.

[citation needed] The first M1064s were converted from M106 mortar carriers, whose 107 mm mortars had been replaced by the 120 mm mortars.
