Officials have confirmed a rare collision between two U.S. Navy ships. Col. Emmanuel Ortiz, a U.S. Southern Command spokesman, said in a statement that the Arleigh Burke-class guided missile destroyer USS Truxtun and the Supply-class fast combat support ship USNS Supply collided during a replenishment-at-sea on Wednesday.

Collisions of U.S. Navy warships are relatively rare but can be fatal. On June 17, 2017, the destroyer USS Fitzgerald collided with MV ACX Crystal, a Philippine-flagged container ship, near Japan, killing seven sailors.

The Navy is looking for armed drones that can be launched from austere locations or from surface warships other than aircraft carriers.

The US Navy’s newest supercarrier was built to send a “100,000-ton message” to rivals. This winter, USS Gerald R. Ford is finally delivering that signal in real time, from the Caribbean to Europe, even as Navy leaders question how often they should lean on such massive ships in a crisis.
