The LVT, or amtrac, was an amphibious vehicle designed from Donald Roebling's Alligator for military operations on land and sea. More than 18,000 were produced between 1941 and 1945. Originally built in Dunedin, Florida, LVTs played a significant role in victory in World War II. The Dunedin LVTs and the Marines stationed in Dunedin served in Guadalcanal in 1942, the first major land offensive in the Pacific, exactly eight months after the attack on Pearl Harbor. In a letter sent from Okinawa in 1945, USMC Major General Roy S. Geiger called LVTs “the work horses of the Marine Corps” and said that except for the amtracs, it would have been impossible for troops to get ashore on Tarawa, Saipan, Guam, or Pelelieu without severe, if not prohibitive, losses. The Dunedin LVT honors Donald Roebling, the history of LVTs, the Spirit of America, Dunedin, the 1st Marine Corps LVT Battalion established in Dunedin and those that followed, all veterans, and all who served the nation.
