The Shughart class large medium-speed roll-on/roll-off ships are strategic sealift assets of the U.S. Military Sealift Command. They can carry up to 58 tanks, 48 tracked vehicles, over 900 wheeled vehicles, and massive deck cargo using two 110-ton cranes and multiple ramps, providing the critical surge capacity needed to rapidly deploy entire Army or Marine units overseas in support of major contingency or humanitarian operations.
