The hospital ship USNS Mercy will set sail Monday for the Seattle area, one of the regions hardest-hit by the coronavirus outbreak, U.S. defense officials told Fox News on Thursday.

The news came a day after Defense Secretary Mark Esper said preparations for the deployment of both the Mercy and the USNS Comfort would be expedited given the urgency with which the ships are needed in their destination areas.

The Comfort, based in Norfolk, Va., is scheduled to deploy to New York City, possibly as soon as April 2 after initially being set to arrive in mid-April, according to Navy officials. The ship has been undergoing extensive maintenance in Virginia, delaying its availability, but top Pentagon officials say they have expedited measures to ready the vessel.

The Mercy is currently docked in San Diego, Calif.

Both ships will carry 750 beds (75 percent of normal capacity) to house trauma patients to reduce the pressure on local hospitals as they deal with the coronavirus outbreak.

The ships also will carry "three times as many medical staffing as normal," a senior U.S. defense official told Fox News.

The surgeon general of the U.S. Navy said Thursday afternoon that medical staffing aboard both hospital ships was set to begin earlier in the day.
