The Navy’s oldest deployable warship takes two days to get to sea

The USS Blue Ridge is the lead ship of her class and the oldest deployable warship in the U.S. Navy.

Assigned to the United States Seventh Fleet based in Yokosuka, Japan, the Blue Ridge is one of the U.S. Navy's two command ships.

When the U.S. Navy's ships are in port and undergoing maintenance, they are put in dry dock — a narrow basin that a ship can sail into and then have all of the water in it drained. This enables workers to access the ship's underside, and enable stability during construction and upgrading operations.

Footage released by the Department of Defense shows that it takes the USS Blue Ridge two days to get out of dry dock.
