Naval Mobile Construction Battalion 13 (NMCB 13), known as the "Lucky 13," is a unit of the United States Navy Seabees. Established during World War II in 1942, the battalion played a vital role in constructing airfields, bases, and infrastructure throughout the Pacific Theater, supporting Allied operations. After deactivation post-war, NMCB 13 was reactivated as a Reserve unit in 1968, contributing to both military and humanitarian missions worldwide. Today, NMCB 13 continues to provide critical construction and engineering support to Navy and joint forces, upholding the Seabee motto, "We Build, We Fight."
