USN:
Essex-class aircraft carrier USS Wasp (CV-18), showing damage to the carrier's bow from her 26 April 1952 collision with Gleaves-class destroyer USS Hobson (DMS-26)
During the night of 26 April 1952 at 2220,
Hobson was steaming in formation with the
aircraft carrier USS Wasp (CV-18) and destroyers
USS Rodman (DD-456) and
USS Ross (DD-563) about 900 kilometres (490 nmi) southeast of
St. John's, Newfoundland during night flight operations en route to
Gibraltar.
Hobson was moving at 24 knots and following the carrier 3,000 yards off her
starboard quarter with
Rodman following
Wasp off her port quarter.
Hobson's commanding officer, Lt. Comdr. William J. Tierney, had been in command of the ship for 5 weeks. He anticipated that
Wasp, preparing to recover her aircraft at 2300, would change course to 250–260 degrees to bring the carrier into the wind, necessary for the aircraft landings. The destroyer's executive officer, Lt. William A. Hoefer, was on the bridge with the
conn and control of the ship when Tierney outlined a course to manoeuvre
Hobson ahead of
Wasp and then come up on the massive carrier's port quarter as the destroyer's new station.
Rodman would move to the starboard quarter as her new station. Hoefer, who had been on
Hobson for 16 months, was immediately concerned when he saw Tierney's plan and turned the conn over to Lt. Donald Cummings, so that he could voice his opposition and belief that Tierney's manoeuvre would put the two ships on a collision course. Since
Wasp had to turn to starboard to recover aircraft, the trailing destroyer had two options, slow down and let
Wasp turn, the conventional method, or cross in front of the carrier. A heated argument ensued that Hoefer lost and he strode off the bridge to the outside wing to cool off.
Meanwhile,
Wasp's commanding officer, Capt. Burnham C. McCaffree, was on his bridge, where Lt. Robert Herbst had the conn and ordered right standard rudder and flank speed to bring the carrier into the wind. McCaffree observed the red aircraft warning lights of the two destroyers and believed that they were also beginning the evolution. Tierney, now in control of
Hobson ordered right standard rudder and a course of 130 degrees. The wind shifted and McCaffree ordered a necessary course change from 260 to 250 degrees to head into the wind. At that time
Wasp's surface radar failed, while on
Hobson, the port
pelorus was fogged, thus preventing an accurate bearing on
Wasp. McCaffree notified the destroyers of his course change, but it is unclear whether anyone on
Hobson's bridge heard the communication. Tierney, without disclosing his intention, was going to put the
Hobson into a
Williamson turn that would bring the ship back to the point she had been. Tierney suddenly ordered full left rudder and within 30 seconds ordered full right rudder. Hoefer rushed back onto
Hobson's bridge when he realized what Tierney was doing and yelled "Prepare for collision!, Prepare for collision!" At that moment, Tierney ordered left full rudder, intending to race ahead of
Wasp which was bearing down on the destroyer. Aboard
Wasp, Lt. Herbst told Capt. McCaffree, "We're in trouble" as McCaffree ordered "all back emergency."
At first it looked as though
Hobson might escape the massive carrier as her bow and number-one stack moved past the carrier's course, but then there was a horrendous, grinding crash as
Wasp struck
Hobson amidships. The force of the collision rolled the destroyer-minesweeper over onto her port side, breaking her in two. The aft section of
Hobson trailed alongside of the carrier while the forward half was temporarily lodged in the
Wasp's bow. The aft part of the ship sank first but 40 of the survivors came from that section as men were literally shot out of a scuttle hatch they had managed to open, propelled by the force of water and expelling air. Aboard the carrier, life rafts were being dropped over and lines lowered. One set of double rafts fell on top of a cluster of five men who were never seen again. One lucky man, a
chief petty officer in the bow, managed to grab a pipe protruding from
Wasp just as
Hobson's bow began her descent under the waves and leaped onto
Wasp without getting wet. Survival for the rest of
Hobson's crew in the thick, glutinous fuel oil was incredible, yet it happened for some.
Rodman and
Wasp pulled aboard 61 oil-coated survivors, but the destroyer and 176 of her crew including Tierney, who dove from the bridge into the sea moments before the carrier plowed into
Hobson, were lost in less than five minutes. Most of the deceased crew were recovered by
Ross and placed on the blood soaked main deck. This horrific incident brought about the tragic end of the destroyer-minesweeper's valiant service
