The objective of this audit was to determine whether the Marine Corps effectively stored and maintained repositioned equipment and supplies aboard Maritime Prepositioning Ships in the Indo‑Pacific region. We focused on the U.S. Naval Ship Dahl, because it was the only ship located in the region that conducted an exercise using Marine Corps prepositioned equipment during our review period. The U.S. Naval Ship Dahl had 647 Marine Corps prepositioned equipment items. Blount Island Command (BICmd) officials, part of the Marine Corps Logistics Command, are responsible for the Marine Corps prepositioning programs.

BICmd officials effectively monitored the contractors’ storage of the 88 prepositioned equipment items in our stratified statistical sample; however, they can improve how they monitor the contractors’ maintenance of some items, such as batteries. BICmd officials did not ensure that the contractors:

• performed or documented semi-annual start-ups for 3 (6 percent) of 52 items requiring that type of maintenance (2 vehicles and 1 radio set); and

• initiated service requests for 5 (6 percent) of 88 prepositioned equipment items, for vehicles with Class III leaks—leaks that form drops that fall from the item.
