The USNS Herschel “Woody” Williams is neither fast nor heavily armed. And while she may look like a commercial cargo ship, the Navy's new vessel is also one of the most useful ships in the entire U.S. military.
Called an “expeditionary mobile base,” the Woody Williams can do just about any job, whether that means supporting a fleet of minesweepers or potentially hosting F-35B Joint Strike Fighters. The Williams was recently christened by builder General Dynamics National Steel and Shipbuilding Company (NASSCO) and is set to join the fleet soon.

One major maritime blog called the USNS Woody Williams “unsexy,” and to be honest it’s not a unfair statement. Call it the cargo pants of boats. The 785-foot long, 164 foot-wide, 90,000-ton ship is based on the civilian Alaska-class oil tanker, also built by NASSCO, and despite the gray paint job it still looks like it. This is where the similarity with an oil tanker ends, however.
