The U.S. and Russian Navies are at odds over an apparent near collision in the Pacific early this morning with each side blaming the other.
The U.S. Navy says the two ships came so close together that the U.S. ship was forced to throw it in reverse and hit the gas.
The Navy says this happened in the Philippine Sea.
The U.S.S. Chancellorsville Cruiser came within 50-to-165 feet of a Russian destroyer.
Russian officials say it was the U.S. warship that instigated the incident.
The U.S.S. Chancellorsville was conducting helicopter operations at the time so it was unable to turn.
