[1] Following her shakedown cruise out of Casco Bay, Maine and post-shakedown availability at the New York Navy Yard, Aaron Ward sailed for the Pacific on 20 May 1942 and proceeded via the Panama Canal to San Diego.Subsequently assigned to screening duties with forces seeking to cover and resupply Guadalcanal, Aaron Ward saw the fleet carrier USS Wasp (CV-7) torpedoed by I-19 on 15 September 1942.The destroyer went ahead at flank speed when she spotted the attackers, to carry out evasive maneuvers and avoid the falling bombs, radically swinging to the right or left as the occasion demanded.For three hours, Aaron Ward shelled Japanese shore positions, her targets ranging from a gun emplacement to ammunition dumps; fires, smoke, and explosions marked her visit as she quit the area.Reaching Lunga Roads, she disembarked her passengers and after going on alert for a Japanese air raid that failed to materialize, cleared Lengo Channel and rejoined her task force.[1] Ten days after this, Aaron Ward carried out another bombardment of Japanese positions on Guadalcanal, this time in company with the light cruiser Atlanta, flagship of Rear Admiral Norman Scott, and destroyers Benham, Fletcher, and Lardner.Arriving off Lunga Point at 0520 on 30 October, the task group stood in, and Atlanta embarked a liaison officer from Major General Alexander A. Vandegrift, Commander of the 1st Marine Division, 20 minutes later.On the evening of 12 November, Aaron Ward retired with her task force – five cruisers and eight destroyers under Rear Admiral Daniel J. Callaghan – in an eastward direction, escorting the transports out of what would become known after the battle as "Ironbottom Sound".At about 0125 on 13 November, the American ships which possessed radar picked up numerous contacts on their screens – the "Volunteer Attack Force" under Rear Admiral Hiroaki Abe, which consisted of battleships Hiei and Kirishima, the light cruiser Nagara, and 14 destroyers.A short time later, after the ship had fired approximately ten salvos, she saw that the cruisers ahead of her had apparently changed course; Aaron Ward observed two torpedoes pass beneath her.[1] A short time later, the destroyer commenced firing on an enemy ship, and hurled some 25 salvos in her direction; her target may have been Akatsuki, which did blow up and sink, with very heavy loss of life.[1] In the minutes that followed, Aaron Ward received eight more direct hits; unable to identify friend from foe and certain that the enemy had surely established her American character, the destroyer then stood out to clear the area.At 0500, Aaron Ward moved slowly ahead, bound for Sealark Channel; ten minutes later, American motor torpedo boats closed, and the destroyer signaled them to ask Tulagi for a tug.
