She was laid down on 1 August 1918 at Bath, Maine by the Bath Iron Works, launched on 10 April 1919, sponsored by Mrs. Washington Lee Capps, the daughter of Admiral Ward and the wife of Rear Admiral Capps.
The ship was commissioned on 21 April 1919 with Commander Raymond A. Spruance in command.

Upon commissioning, the destroyer reported for duty with Destroyer Division 13 (DesDiv 13), Destroyer Squadron 2 (DesRon 2), Atlantic Fleet.
She performed her first significant service for the Navy at Trepassey Bay in May 1919 when she served as one of the pickets for the transatlantic flight attempt by three Curtiss NC flying boats.
One of the boats—NC-4—completed the flight successfully.
Aaron Ward continued to serve with Atlantic Fleet until September, at which time she was transferred to the Pacific.
Her first assignment there consisted of a month of salvage operations in Angeles Bay, Baja California, Mexico, to recover a downed Army DH.4B observation plane and the bodies of its crew who had been murdered by Mexican fishermen.
At the conclusion of that mission, she began training operations with the Battle Fleet.
On 17 July 1920, the Navy adopted the alphanumeric system of hull designations, and Aaron Ward became DD-132 (before this, she had been Destroyer No.
132).
Her work with Battle Fleet was interrupted early in 1921 by two rescue missions near the Panama Canal Zone.
Between January and March of that year, she cruised the waters along the coast of the Canal Zone searching for the flying boat NC-6, which had crashed in the vicinity.
In February, she turned from that mission to pursue another errand of mercy, the rescue of survivors from  the destroyer Woolsey which had sunk after a collision with the merchant vessel SS Steel Inventor on 26 February.
Aaron Ward resumed normal duty with the Battle Fleet in March 1921, and continued that duty until she was decommissioned on 17 June 1922 and berthed with the Reserve Fleet at San Diego.

The destroyer remained inactive for almost eight years, and then was recommissioned at San Diego on 24 May 1930.
After active service until mid-1932, she entered the Rotating Reserve in which she alternated active periods at sea with intervals of inactivity at pierside with a minimal crew embarked.
The ship continued in that status until December 1934, when she returned to full activity.
On 1 April 1937, the destroyer once more was placed out of commission and returned to the Reserve Fleet.
On 30 September 1939, Aaron Ward came out of reserve for the final time.
Recommissioned on that day (in response to President Franklin D. Roosevelt's establishment of the Neutrality Patrol following the outbreak of war in Europe at the beginning of the month), she became flagship of DesDiv 65, Pacific Fleet.
In December, she was transferred to the Atlantic Fleet and, on the 11th, arrived at Key West, Florida.
For the rest of her U.S. Navy career, she conducted neutrality patrols in the Gulf of Mexico and in the West Indies.
