Joshua Humphreys served in the United States Atlantic Fleet under MSC control until taken out of active service on 29 June 1996, the second ship of her class to be deactivated. She was subsequently berthed at the Naval Inactive Ship Maintenance Facility (NISMF) at the site of the former Philadelphia Navy Yard in Philadelphia, Pennsylvania, and placed in reserve.

In March 2010 Atlantic Marine in Philadelphia was awarded a $12.8 million contract for the reactivation of the Joshua Humphreys. Upon reactivation, she joined the US Fifth Fleet in support of counter-piracy and counter-terrorism operations in the Indian Ocean and Gulf area. As 11 November 2010 she was providing fuel to the USS Abraham Lincoln (CVN-72) Carrier Strike Group.
