PHIBCB ONE

PHIBCB ONE, or **Naval Mobile Construction Battalion ONE (PHIBCB ONE)**, was established in 1942 as part of the U.S. Navy’s efforts to provide specialized construction capabilities for amphibious operations during World War II. The unit played a critical role in the Pacific Theater, constructing and maintaining essential port and beach facilities to support landing forces during major campaigns. Over the decades, PHIBCB ONE has continued to support U.S. Navy and Marine Corps operations, specializing in ship-to-shore movement of troops, equipment, and supplies. Today, the battalion remains an essential element of the Naval Construction Force, ready to deploy worldwide in support of both combat and humanitarian missions.
