The US Army decided in February 1941 that it should have airborne forces with armor support. General Motors, Christie, and Marmon-Herrington were asked to submit designs in May 1941.

500 were ordered in April 1942 before service tests had begun. Eventually 1,900 were ordered but due to design changes and manufacturing problems only 830 were delivered.

No suitable glider or aircraft to transport it was found.
