43rd anniversary of the naming of the M1 Abrams Main Battle Tank on 28 February 1980. On that day, the first Low Rate Initial Production (LRIP) Abrams tank came off the line at the Lima Army Tank Plant in Lima, Ohio.
Still classified as the XM1, the tank bore the name of "Thunderbolt", which was the name General Creighton Abrams (former 37th Tank Battalion Commander and later Army Chief of Staff) had bestowed on all his M4 Shermans in World War II. The General's family was in attendance as the Army announced the new tank would be named for the renowned Armor Officer, who had died in 1974. The Abrams has since served in theaters around the world with multiple with upgrades to its firepower and protection.
The Collection is home to an M1 that even earlier than the first production tank. The first Full-Scale Engineering Development (FSED) XM1, with serial number PV001, was built in 1978 and heavily used in field testing. Today, it is the oldest M1 in the U.S. Army inventory.
