Assault Craft Unit TWO , (ACU-2) is an Atlantic Ocean Maritime Prepositioning Force in the United States Navy operated under Naval Beach Group TWO out of Naval Amphibious Base Little Creek, Virginia. ACU-2's force consists of Landing Craft Utility boats (LCU), Landing Craft Mechanized, Mark 8 boats (LCM), and Maritime Prepositioning Force Utility Boats (MPFUB). The sister unit of ACU-2 is Assault Craft Unit 1 in Naval Amphibious Base Coronado.
Following WWII and the rise of the importance of a Sea to Shore connection, all Landing Craft were organized into Beach Party Battalions. The Beach Party Battalions joined and formed the Naval Beach Group TWO. Furthermore, in 1949 Boat Unit TWO and Beachmaster Unit TWO were added to Naval Beach Group TWO. Boat Unit TWO originally had LCM-6 craft and later gained the LCM-8 in 1957 and gained LCU's in 1959 when it merged with Landing Craft Squadron TWO. After the merger, Boat Unit TWO changed it name to Assault Craft Unit TWO (ACU TWO).
