A transportation heavy boat company's mission is to provide and operate landing craft, utility (LCU's), for transporting personnel and heavy cargo in offshore discharge operations, and to augment lighterage service in a harbor, in inland or coastal water, or on the open sea, including lighterage service required in joint amphibious or other waterborne tactical operations. A heavy boat company is assigned and attached to organizations similar to those to which the light boat company is assigned and attached. It may operate separately under an appropriate staff transportation officer.

5th Heavy Boat Transportation unit was known as the Pacers and provided ship to shore transportation of men and material for the U.S. Army in large Vietnamese harbors.
