At first glance, it might seem like this mammoth U.S. Navy aircraft carrier is about to visit Davy Jones' Locker, but despite its exaggerated tilt, the ship is just performing a training exercise.
In the below photo, the USS Harry S. Truman, a nuclear-powered Nimitz-class supercarrier, performs sea trials in the Atlantic Ocean on July 8, 2012. Its reactor was recently upgraded, and these tests are part of a regimen designed to check the ship's seaworthiness.
The high-speed exercise is called a swing check. It tests the ship's ability to stop the movement of its bow by counter-steering. To "check your swing" is one of several U.S. Navy and Coast Guard helm commands that concern the ship's rudder.
The USS Harry S. Truman is the eighth Nimitz-class aircraft carrier in the U.S. Navy fleet. It served in the Persian Gulf during Operation Iraqi Freedom in 2004-2005 and was the naval task force flagship in response to Hurricane Katrina.
