One of a new class of fast escort vessels designed for convoy work, Hooper conducted shakedown training out of her home port, San Diego, before deploying with the 7th Fleet.

The escort vessel took part in antisubmarine operations and joined the vital Formosa Patrol before returning to the United States 9 April 1959.

Entering the yard at Hunter's Point in March, the ship had her aft 3-inch mount replaced with a helicopter flight deck and a single 20 mm cannon to increase her versatility, and also had the newest sonar equipment installed.

Returning to her regular pattern of deployments to the Far East, Hooper continued to play an important role in keeping the peace in this vital area.

En route the ship assisted in the search for a downed Royal Thailand Army DC-3 aircraft carrying Brigadier General Joseph Stilwell Jr.
