It's a floating hospital that's traveled the world serving others.
The USNS Comfort does everything from medical to dental -- even veterinary work.
Tuesday, the ship was headed back out to sea as a part of Continuing Promise 2013.
USNS Comfort has been docked in Baltimore for 25 years. As a part of the mission, it will now be docked at home in Norfolk, Virginia.
Baltimore's loss is worth what's gained by USNS Comfort's deployment.
From early April though August, Continuing Promise 2013 will provide health care and construction projects in eight countries: Belize, Costa Rica, Guatemala, Honduras, El Salvador, Jamaica, Nicaragua and Peru.
Hundreds of surgeries are expected to be performed aboard the Comfort, and thousands of patients will be treated ashore - an effort that Rear Adm. Sinclair Harris, the U.S. Naval Forces Southern Command and 4th Fleet commander, called "real work for real people that will make a real difference in their lives."
