History

World War II – 104th Naval Construction Battalion
ACB-1 was originally commissioned at Camp Peary, Williamsburg, Virginia, 16 July 1943, as the 104th Naval Construction Battalion and was sent to Camp Endicott, Gulfport, Mississippi. During World War II CBs sent to the Pacific were attached to one of the four Amphibious Corps: I, III, and V were U.S. Marine Corps while VII Amphibious Corps was U.S. Army. During WWII there were five battalions tasked with pontoons, barges and the building of ship to shore causeways: CBs 70, 81, 111, 128, and 302. The 104th was attached to VII Amphibious group in 1943 and sent to Gamadodo, Milne Bay, New Guinea; Australia in 1944; and Leyte, Philippine Islands, 1945. During these two years, the 104th completed numerous land based construction projects ranging from an airfield on Los Negros Island, in the Admiralties, to Naval Air Station Cubi Point on island of Leyte in the Philippines. The battalion was eventually deactivated in Dec 1945.
In January 1947, the 104th was reactivated and first began their Amphibious mission when the unit was tasked with "the assembly and placement of pontoon structures, beach rehabilitation, harbor development, salvage, and training of reservist in these operations". In October 1950, it was recognized by the Chief of Naval Operations, Admiral Forrest Sherman, that the 104th and 105th NCBs had specialized capabilities that separated them from the other Naval Construction Battalions and were re-designated Amphibious Construction Battalion One and Two.
Korean War – Amphibious Construction Battalion ONE

During the Korean War several detachments were deployed to the Western Pacific in support of amphibious operations. In the September 1950, invasion of Inchon a pontoon causeway was brought into Inchon Harbor on D-Day plus 1 to be used a tide level landing. General Douglas MacArthur came ashore over this pier on D plus 2.
A month after 15 September 1950, landing at Inchon, ACB-1 moved to the east coast of Korea and again supported the 1st Marine Division. This time they landed at the port city of Wonsan as part of the 1st Marine Division's shift from the Inchon-Seoul area to the northeast coast of Korea. While the Marines moved north to positions in the Chosin Reservoir area, the Seabees built piers and unloaded ships.
Operation Crippled Chick: The assignment to build the emergency landing strip behind enemy lines on Yo Do island, fell to ACB-1s Detachment George. Led by Lt. T.E. Rowe, Detachment George was composed of one warrant machinist, six chief petty officers and 69 Seabee enlisted men. Six of these Seabees had landed at Inchon two years earlier. The seabees named the runway Briscoe Field for the Commander of the fleet Admiral Robert P. Briscoe
Vietnam
ACB 1 was the first CB to deploy to Vietnam as a component of Task Force 90 "Passage to Freedom" in 1954. That year an agreement was reached in Geneva recognizing the Communist government of North Vietnam which allowed for people residing in the North to move South before 15 May 1955. Both ACBs were assigned to TF-90. Nine years later, in 1964 ACB 1 would return as the first CB in the Vietnam war.
Gulf War – Somalia – Persian Gulf
In August 1990, PHIBCB ONE was the first Naval Construction Force unit to deploy to Saudi Arabia in support of Operation Desert Shield. The Battalion assisted in the successful offload of the ships from Maritime Prepositioning Squadron TWO and Maritime Prepositioning Squadron THREE in support of the First Marine Expeditionary Force and provided some limited technical support to other joint units operating in the area.
On 10 December 1992, ACB-1 arrived at Mogadishu as part of the Naval Support Element in Somalia. Within a short time ACB-1 unloaded five of the Marines' Maritime Pre-positioning Force ships, refurbished the port, and provided fuel and water for military forces in Somalia.
In August 1994 and again in August 1995, the command deployed the Offload Preparation Party for Maritime Prepositioning Squadron TWO in support of Operation Vigilant Warrior and Operation Vigilant Sentinel in the Persian Gulf due to the threat of resurgence of Iraqi aggression. In each case the personnel returned home after a couple months but were in a 48hr standby until March 1996.

The Battalion was the first Naval Construction Force unit to deploy during Operation Desert Shield.

Most recently, in January 2003, ACB-1/2 was deployed to Kuwait Naval Base, Kuwait in support of Operation Enduring Freedom and Operation Iraqi Freedom. Moving over of cargo, on nine C-5 Galaxy aircraft, the PHIBs constructed the largest Logistics Support Area in ACB history, housing over 4,500 personnel. Additionally, ACBs were instrumental with the complete download of 13 MPF ships encompassing three MPSRONs. ELCAS-M was also deployed to move thousands of ammo containers from ship to shore. A small detachment from ACB-1 also moved forward in Iraq to assist the NMCBs with the anchoring of a floating bridge.

In 2005 ACB 1 took part in the U.S. military's Operation Unified Assistance response to the Indian Ocean tsunami.
