America Needed Airfields Faster Than Japan Could Bomb Them. So Caterpillar Went to War.

Dwight D. Eisenhower and Admiral Halsey both named the bulldozer as a primary reason for victory in their respective theaters. This presentation examines how a machine built for farms and road construction became a critical tool on the front lines of World War II. From the Seabees clearing pillboxes on Mono Island to the rapid construction of B-29 runways on Tinian, this history traces the operational life of the bulldozer across the Pacific. You will see how these machines were used to fill bomb craters at Guadalcanal and clear paths off Omaha Beach under heavy fire. Every account detailed here is sourced from official unit records, award citations, and first-hand reports. By examining these documents, we can understand why military leadership prioritized this heavy equipment over traditional combat gear to secure key logistics. Beyond the battlefield, we look at the production efforts at Caterpillar and the contributions of Robert LeTourneau in scaling this technology for war. NEW BOOK: America Needed It.
