The first three ships of MPS Squadron TWO raced from their Diego Garcia homeport to reach Saudi Arabia 15 August, marking the first use of the MPS in an actual crisis. Within four days of their arrival in the port of Jubail, Navy cargo handlers averaging 100 lift-hours per day offloaded more equipment and supplies from the three 755-foot ships than could have been moved by 3,000 C-141 cargo flights. The 16,500 Marines of the 7th Marine Expeditionary Brigade (MEB), a component of the 1st Marine Expeditionary Force (MEF), arrived via the Military Airlift Command. They "married-up" with the MPS equipment and were ready for combat on 25 August-- the first heavy ground combat capability in-theater.
The five ships of MPS Squadron TWO brought the essentials to support the 7th MEB Marines for 30 days of combat-- food, water, fuel, millions of pounds of ammunition for aircraft, artillery and small arms, construction materials and medical supplies. The balance of the equipment for the 1st MEF arrived from Guam aboard the ships of MPS Squadron THREE. Delivering all the equipment delivered by MPS ships to the 45,000 men of the 1st Marine Division would have required 2100 lifts by C-5s, our largest military transport aircraft.
