On Thursday, the Russian frigate Yaroslav Mudryy came within 150 yards of the guided missile cruiser USS San Jacinto — two weeks after the same Russian ship came within 315 yards of the American destroyer USS Gravely.

The USS San Jacinto was operating near the aircraft carrier USS Dwight D Eisenhower in the eastern Mediterranean Sea, where it is conducting flight operations against ISIS targets in Iraq and Syria.

According to Captain Danny Hernandez, a spokesman for U.S. European Command, the Yaroslav Mudryy positioned itself about 650 yards from the American cruiser. “Then, Yaroslav Mudryy repeatedly informed San Jacinto over VHF radio of its intended course, as the Yaroslay Mudryy maneuvered towards and unnecessarily close to USS San Jacinto before turning away,” said Hernandez.
