About this Unit
Naval Mobile Construction Battalion 53 (MCB-53), known as a "Seabee" battalion, was commissioned by the United States Navy during World War II. Activated in 1942, MCB-53 played a vital role in constructing airfields, bases, and other critical infrastructure in the Pacific Theater, supporting major operations such as the campaigns in the Philippines and Okinawa. The battalion was recognized for its ability to work under combat conditions, often building vital facilities while under enemy fire. After the war, MCB-53 continued to serve in various overseas locations before eventually being decommissioned as part of postwar drawdowns.
