"Let me in," said George Sandoval, who told Eyewitness News he'd been waiting for close to three hours to see the independent variant littoral combat ship. "I'm not going to get in. I want in."

The ship is the 16th to be named for a woman and the 13th named for a living person since 1850. It is 419 feet in length and was built in Mobile, Alabama. Its home port will be San Diego.
