May 9, 2017: A 60- to 70-foot South Korean fishing boat collided with the Lake Champlain, a guided-missile cruiser, on its port side while the cruiser was conducting routine operations in international waters. No one was injured. Fishing boat crew members later said the fishing vessel did not have a radio, so they did not hear the calls from the Navy, a Navy official said at the time.

Aug. 19, 2016: The Louisiana, a nuclear ballistic-missile submarine, and the Eagleview, a Military Sealift Command support vessel, collided while conducting routine operations in the Strait of Juan de Fuca off the coast of Washington State. There was damage to the hulls of both the Eagleview and the Louisiana. No one was injured.

Nov. 20, 2014: The Amelia Earhart and the Walter S. Diehl collided during an exchange of goods in the Gulf of Aden. Both ships resupply Navy warships for the United States Fifth Fleet, which is based in Manama, Bahrain. No one was injured. The accident happened during a tricky maneuver used by United States Navy and allied ships in which they come within 150 feet of each other to be resupplied with fuel and food without pulling into a port, according to the Navy’s website.

July 22, 2004: The John F. Kennedy, an aircraft carrier, and a dhow, a small traditional Arab sailing boat, collided in the Persian Gulf. The dhow sank immediately, and all those aboard are believed to have died. It is still unclear how many people were on it, but dhows — which are used mainly for transportation and fishing — can generally carry up to 15 people.

The Kennedy, which was engaged in night air operations at the time, had made a hard turn to avoid the tiny vessel. The carrier was unscathed from the impact on its starboard hull; its crew and aircraft were all accounted for, but two jet fighters on the deck were damaged when the ship turned. The Navy relieved Stephen G. Squires, the commanding officer of the Kennedy, after the episode.
