On Thursday, 09 January 2020, while conducting routine operations in the North Arabian Sea, USS Farragut (DDG 99) was aggressively approached by a Russian Navy ship.
Farragut sounded five short blasts, the international maritime signal for danger of a collision, and requested the Russian ship alter course in accordance with international rules of the road. The Russian ship initially refused but ultimately altered course and the two ships opened distance from one another. While the Russian ship took action, the initial delay in complying with international rules while it was making an aggressive approach increased the risk of collision.
The statement from the U.S. Navy states that the armed force “continues to remain vigilant and is trained to act in a professional manner. We continue to encourage vessels from all nations to operate in accordance with internationally recognized maritime laws, standards and norms.”
