MOBILE, Ala. (AP) - A new U.S. Navy ship named in part for a county in Oklahoma has been christened at a shipyard in Mobile.

U.S. Navy Secretary Ray Maybus was the keynote speaker at Saturday's christening of the USNS Choctaw County at the Austal USA shipyard. He told WKRG-TV the new ship will transport Marines and soldiers across oceans.

It's the second joint high-speed vessel to come from Austal's Mobile facility.

The ship is named after Choctaw County in Oklahoma, Choctaw County in Mississippi and Choctaw County in Alabama.
