Arthur W. Radford
On 4 February 1999 at about 23:34, "Arthur W. Radford" collided with the "Saudi Riyadh", () a 29,259-ton, -long, roll-on/roll-off container ship, which was preparing to enter the Chesapeake Bay bound for Baltimore. According to the Navy, "Arthur W. Radford" was conducting calibration tests on electronic warfare equipment at the time of the collision. As a part of that test, the ship had been sailing in circles around an electronic buoy for six hours prior to the collision. "Saudi Riyadh", meanwhile, was approaching the Chesapeake Bay from the northeast, preparing to line up in the shipping lanes before taking on a marine pilot for its eventual trip to Baltimore.
