The M113 Armored Personnel Carrier (APC) helped to revolutionize mobile military operations since it was developed from the M59 and M75 APCs by Ford and Kaiser Aluminium in the late 1950s. Its first use was in Vietnam were the M113 was extensively deployed with great success.
The M-113 Armored Personnel Carrier (APC) is possibly the largest family of armored tracked vehicles, with over 72,000 vehicles worldwide and more than 40 different variants. Originally developed in the late 1950s, the M113 family of vehicles (FOV) is still in service in the U.S. Army and in the military of many other countries.
M-113 Armored Personnel Carrier (APC) Family of Vehicles
The M113 vehicles carried eleven soldiers plus a driver and track commander under armor protection across hostile battlefield environments. The M113 is air transportable, air-droppable, and swimmable, allowing planners to incorporate APCs in a much wider range of combat situations, including many 'rapid deployment' scenarios.
The M113s were so successful that they were quickly identified as the foundation for a family of vehicles. Over the years, the M113 FOV has undergone numerous upgrades and development of derivitive configurations, including the M577 command track and the M106 mortar carrier. In 1964, the M113A1 package replaced the original gasoline engine with a 212 horsepower diesel package, significantly improving survivability. In 1979, the A2 package of suspension and cooling enhancements was introduced.
The M113A3 RISE (Reliability Improvements for Selected Equipment) package includes an upgraded propulsion system (turbocharged engine and new transmission), greatly improved driver controls (new power breaks and conventional steering controls), external fuel tanks, and 200 AMP alternator with 4 batteries. Additional A3 improvements include incorporation of spall liners and provisions for mounting external armor. The rear-mounted external fuel tanks make the M113A3 visually distinct from earlier variants. The M113A3 was introduced in 1987.
The M113A3 fleet will include vehicles with high speed digital networks and data transfer systems. The M113A3 digitization program includes applying appliqué hardware, software, and installation kits and hosting them in the M113 FOV.
