LPD-25 USS Somerset is a San Antonio-class amphibious transport dock of the United States Navy. It is the fourth United States Navy vessel and the second warship to bear this name, the first two being a wooden-hulled motorboat and a ferry. The first warship, an armed cargo ship from World War II, was named for the Somerset counties of Maine, Maryland, New Jersey and Pennsylvania. The modern ship was named specifically for Somerset County Pennsylvania, in honor of the passengers who died on United Airlines Flight 93, which was hijacked during the terror attacks of 11 September 2001. The passengers prevented the plane from reaching its intended target by forcing it to crash in Stonycreek Township in Somerset County, Pennsylvania. The words "Let's Roll," spoken by a passenger of United Airlines Flight 93 before trying to storm the cockpit of the doomed flight, are painted on the ship above the rear deck, along with a "93" seal which mirrors the "93" flag seen flying on the vessel in many photos.
