The amphibious landing transport USS Somerset is named for the Pennsylvania county where the hijacked United Airlines Flight 93 crashed after passengers fought back against a terrorist takeover.
The ship is the last to be built at the Huntington Ingalls Shipyard in suburban Avondale. The yard is scheduled to close in 2013; its workforce has been cut nearly in half since 2010.
The Somerset's sister ships are the New York and Arlington. Each carries steel salvaged from the 9/11 wreckage. The Somerset has a room set aside with a display of 9/11 artifacts.
