The U.S. Navy owns the oceans, ensuring freedom of navigation for allies and fighting fiercely when called upon.

But the Navy has a softer side too, filled with humanitarian relief and medical missions.The crown jewels of this effort are the USNS Mercy and the USNS Comfort — hospital ships with a thousand beds each.

1. The USNS Mercy and her sister ship were converted from massive supertankers. Each is 70,000 metric tons.
