After her May 1915 commissioning, O'Brien sailed off the east coast and in the Caribbean. She was one of seventeen destroyers sent out to rescue survivors from five victims of German submarine U-53 off the Lightship Nantucket in October 1916. After the United States entered World War I in April 1917, O'Brien was sent overseas to patrol the Irish Sea out of Queenstown, Ireland.
After returning to the United States in January 1919, O'Brien revisited European waters in May to serve as one of the picket ships for the NC-typeseaplanes in the first aerial crossing of the Atlantic. O'Brien was decommissioned at Philadelphia in June 1922. She was struck from the Naval Vessel Register in March 1935 and sold for scrapping in April.
Design and construction
O'Brien was authorized in March 1913 as the lead ship of the O'Brien class, which was an improved version of the Cassin-class destroyers authorized in 1911. Construction of the vessel was awarded to William Cramp & Sons of Philadelphia which laid down her keel on 8 September 1913. On 20 July 1914, O'Brien was launched by sponsor Miss Marcia Bradbury Campbell, great-great-granddaughter of Gideon O'Brien, one of the ship's namesakes. Gideon and his four brothers—John, William, Dennis, and Joseph—were crewmen aboard sloop Unity, under the command of their brother Jeremiah O'Brien, when that vessel captured HMS Margaretta on 12 June 1775 during the American Revolutionary War; the destroyer O'Brien was named after all six brothers, and was the second US Navy vessel named in their honor.[1] As built, the destroyer was 305 ft 3 in (93.04 m) in length, 31 ft 1 in (9.47 m) abeam, and drew 9 ft 6 in (2.90 m).[1][3] The ship had a standard displacement of 1,050 long tons (1,070 t) and displaced 1,171 long tons (1,190 t) when fully loaded.[3][4]
O'Brien was commissioned into the United States Navy on 22 May 1915 after which she conducted her shakedown cruise between Newport, Rhode Island, and Hampton Roads, Virginia.[1] In fleet exercises off New York in November, O'Brien collided with the destroyer Drayton, in a minor incident that carried away part of Drayton's topmast and wireless gear.[9] In December, she was assigned to the 5th Division, Torpedo Flotilla, Atlantic Fleet. From early 1916-spring of 1917, she operated with the Fleet along the East Coast and in Cuban waters.
At 05:30 on 8 October 1916, wireless reports came in of a German submarine stopping ships near the Lightship Nantucket, off the eastern end of Long Island. After an SOS from the British steamer SS West Point was received at about 12:30, Rear Admiral Albert Gleaves ordered O'Brien and other destroyers at Newport to attend to survivors.[10][Note 2]
The American destroyers arrived on the scene at about 17:00 when the U-boat, U-53 under the command of KapitänleutnantHans Rose,[Note 3] was in the process of stopping the Holland-America Line cargo ship Blommersdijk. Shortly after, U-53 stopped the British passenger ship Stephano.[12] As Rose had done with three other ships U-53 had sunk earlier in the day,[Note 4] he gave passengers and crew aboard Blommersdijk and Stephano adequate time to abandon the ships before sinking the pair.[13][14] In total, 226 survivors from U-53's five victims were rescued by the destroyer flotilla.[15]
In February 1917, one of O'Brien's gun crews hit a target at 5,000 yd (4,600 m) eight times in eight attempts with one of the destroyer's 4 in (100 mm) guns, a feat which earned the crew and O'Brien recognition in The Independent, a weekly newsmagazine published in Boston.[16]
World War I
Returning from winter maneuvers off Cuba in March 1917, the ship was in the York River when the United States declared war on Germany on 6 April, entering World War I. After fitting out at Brooklyn Navy Yard, she got underway from New York on 15 May with Cummings,[1][17]Nicholson,[18]Cushing,[19] and Sampson,[20] and joined convoy at Halifax, Nova Scotia, en route to Ireland. Upon arrival at Queenstown on 24 May, O'Brien was assigned to the 6th Destroyer Division which cooperated with the British forces. She patrolled off the Irish coast in company with other destroyers answering distress calls and meeting eastbound convoys to escort them through the war zone.[1]
While escorting SS Elysia 12 nmi (14 mi; 22 km) off Queenstown on 16 June, lookouts on O'Brien sighted a periscope. Heading toward the submarine for an attack, a lookout in the foretop saw the submerged boat pass close along the starboard side. A depth charge was dropped but no immediate evidence of damage was found. Nearly three hours later, the British vessel HMS Jessamine reported a large patch of oil in approximately the same position. The next morning, Cushing also reported and confirmed Jessamine's report. The British Admiralty believed the submarine was probably seriously damaged. However, later investigation reveals that German submarine U-16, the submarine in question, continued to operate and completed her cruise.[1]
In the summer of 1918, O'Brien was transferred to the French coast where she continued her antisubmarine patrols through the end of the war.[1]
Inter-war period
After the signing of the Armistice on 11 November, which ended all fighting, O'Brien transported mail and passengers between Brest, France, and Plymouth, England.[1] She returned to New York on 8 January 1919,[1] but returned to European waters in May when she served as one of the rescue pickets stationed along the route across the Atlantic flown by three Navy NC-typeseaplanes in the first aerial crossing of the Atlantic.[21]
^The 50 denotes the length of the gun barrels; in this case, the gun is 50 calibers, meaning that the gun is 50 times as long as its bore, or 200 inches (5.1 m) in this case. The Mark number is the version of the gun; in this case, the ninth US Navy design of the 4-inch/50 gun.
^U-53 had called at Newport on 7 October 1916, the day before the attacks, to drop off a letter for Johann Heinrich von Bernstorff, the German Ambassador to the United States, and had exchanged courtesy visits with Admirals Albert Gleaves and Austin M. Knight before departing.
