M113 Armoured Personnel Carrier, United States of America
The M113 armoured personnel carrier was developed by the FMC (Food Machinery Corp.) based on M59 and M75 armoured personnel carriers from the 1950s. The first prototype of M113 was produced in 1957. The US Army adopted the vehicle in 1960. Kaiser Aluminum and Chemical produced the aluminium required for the development of M113.
FMC transferred the production of M113 vehicles to its new subsidiary, the United Defense in 1994. United Defense was acquired by BAE in 2005.
As of November 2011, more than 80,000 M113 vehicles were produced in different variants. The vehicle is operational in more than 44 countries.
