Beachmaster Unit was formed from the Navy Shore Party of
World War II. The Shore Party formed the nucleus to which the various land and naval elements were assigned for an operation. The naval elements included the
Underwater Demolition Team, a Naval Pontoon Unit, and a Boat Pool. Units called Beach Parties were formed and were composed of members of the ship's crew to ensure the mass movement and orderly flow of troops, equipment and supplies, through the surf zone, onto the hostile shore, and across the assault beaches to achieve the success of the amphibious operations. The original units consisted of approximately two officers and thirty men, to support the landing of the battalion of troops. In July 1948, the
Chief of Naval Operations ordered the commissioning of the Beachmaster Unit as a separate command with designation as
Beachmaster Unit One. Due to the operational need for a Forward Deployed Naval Force (FDNF) NBG-1 created a Western Pacific Detachment (WESTPAC DET) consisting of LCACs, LCUs, and BPTs all in one geographical location, combining a Beach Master Unit and an Assault Craft Unit for the first time in naval history. This WESTPAC DET was commissioned on August 1, 2012, into Naval Beach Unit Seven(NBU-7) and is no longer associated with BMU-1. Naval Beach Unit (NBU) 7 and the 1224th Engineering Support Company, Guam Army National Guard worked together to load heavy equipment vehicles onto the amphibious dock landing ship for transport to
Saipan in support of disaster relief efforts after
Super Typhoon Yutu on November 6, 2018. In November, 2019 the unit participated in
Tiger Triumph, the first-ever tri-service exercise involving the U.S. Navy and Marine Corps and Indian Army, Navy and Air Force. Naval Beach Unit (NBU) 7 held a change of command ceremony onboard Commander, Fleet Activities Sasebo where Commander Greta Densham was relieved by Commander Kirk Sowers, Dec. 12 2019. == Awards ==
