Today the U.S. Navy commissioned a new ship,
the USS Somerset.
She's a San Antonio-Class amphibious transport dock, built in part with metal salvaged from United Airlines Flight 93.
United Flight 93 crashed in Somerset County, Pennsylvania on September 11, 2001, when the passengers attempted to re-take the Boeing 757 from the hijackers who intended to use it as another weapon of mass destruction.
The USS Somerset can launch hovercraft to deliver disaster relief supplies, angry Marines or anything in between, wherever the need arises.
