PHIBCB ONE

• Legacy of World War II: PHIBCB ONE traces its origins back to the storied Naval Construction Battalions (“Seabees”) that played a vital role in amphibious operations during WWII, laying the foundation for modern amphibious construction units. • Establishment: Amphibious Construction Battalion ONE (PHIBCB ONE) was officially commissioned on 10 July 1943, making it one of the oldest units of its kind in the U.S. Navy. • Nickname: The unit is often referred to as “The Fleet’s Workhorse” because of its reputation for handling tough, critical, and rapid construction missions in support of amphibious and expeditionary operations. • Beach Support: PHIBCB ONE specializes in ship-to-shore logistics, including constructing beach causeways, operating pontoon systems, and establishing beach support areas under combat conditions. • Korean War Contributions: The battalion played a key role during the Korean War, establishing and maintaining critical beachhead infrastructure during the historic Inchon landings in 1950. • Vietnam War Operations: PHIBCB ONE supported numerous amphibious landings and logistical missions throughout the Vietnam War, enhancing the Navy’s ability to project power ashore. • Humanitarian Missions: Beyond combat, PHIBCB ONE has participated in disaster relief, including tsunami response in Southeast Asia and earthquake assistance in Haiti, showcasing its versatility and humanitarian commitment. • Innovations: The battalion is known for pioneering the use of the Elevated Causeway System (ELCAS), a modular pier that dramatically increases the speed and efficiency of offloading cargo from ships to shore. • Training and Readiness: PHIBCB ONE regularly participates in major joint and combined exercises, such as RIMPAC and Pacific Partnership, ensuring readiness for both military and civil contingency operations. • Motto and Emblem: The unit’s motto, “We Build, We Fight,” reflects its dual mission of construction and combat support. Its emblem features the iconic Seabee wielding a hammer and machine gun, symbolizing strength and versatility.
