What is lpd-29?

As an AI language model, I do not have access to sensitive or classified information, but based on public sources, LPD-29 is a San Antonio-class amphibious transport dock ship, designed to support amphibious assault, special operations or expeditionary warfare missions. Its primary mission is to transport and deploy Marines, their equipment, and supplies. The ship is capable of handling air-cushioned landing craft, amphibious assault vehicles, and other surface craft.
