Upon being commissioned, Hollandia underwent a shakedown cruise down the West Coast to San Diego.
Shakedown continued as she underwent a transport mission, carrying a load of replacement aircraft and military personnel.
She departed on 10 July, bound for Espiritu Santo.
On her return trip, she stopped at Manus and Guadalcanal, before arriving at Port Hueneme, California on 27 August.
For the next few months, Hollandia continued these transport missions to the West and South Pacific, transporting supplies and passengers.

She continued these duties until 1 April 1945, at which point she was anchored at Ulithi.
As U.S. forces began their landings, beginning the Battle of Okinawa, Hollandia joined the Special Escort Carrier Group as its flagship.
She, along with White Plains, Sitkoh Bay, and the 
Bogue-class escort carrier Breton, transported Marine Air Groups 31 and 33 to land bases captured on Okinawa.
In total, the air group being transported consisted of 192 Vought F4U Corsair and 30 Grumman F6F Hellcat fighters.
Hollandia was delegated to take on the planes of Marine Air Group 33.
After departing on 2 April, the destroyers Kilty, Manley, George E. Badger, and Greene provided a screen for the carriers.

The escort carriers managed to safely arrive at Okinawa on 6 April, although the destroyers dropped depth charges to deter a suspected submarine en route.
There, Hollandia prepared to begin launching her aircraft, which would be the first land-based aircraft to support the U.S. forces fighting their way down the island.
However, she, along with White Plains, were ordered to postpone their launchings for several days, as the transport ships ferrying the equipment of the marines had been attacked and damaged, with much equipment lost.
On 9 April, she launched her planes to the hastily expanded Kadena Air Base, where the aircraft began operations.
Marine Fighter Attack Squadron 323, transported aboard the escort carriers, would go on to become the highest-scoring air unit participating in the Battle of Okinawa, claiming 124.5 Japanese planes.

Having completed her duties, she returned to San Diego, arriving on 1 May. Whilst at port, Captain John Thompson Brown, Jr. took over command of the vessel.
She then conducted a transport run to Pearl Harbor, ferrying cargo and passengers.
On 7 June, she departed the West Coast to serve as a replenishment carrier, supporting the Fast Carrier Task Force in its operations against Japan.
Replenishment carriers enabled the frontline carriers to replace battle losses, and to stay at sea for longer durations of time.
Hollandia loaded replacement aircraft at Pearl Harbor, and she sailed on 18 June to join Task Group 30.8, the Fleet Oiler and Transport Carrier Group (also known as the At Sea Logistics Service Group).
She provided replacement aircraft up until news of the Japanese surrender broke.

Post-war, Hollandia berthed at Guam, where overhaul was conducted to transform her into a passenger ship.
She then joined the Operation Magic Carpet fleet, which repatriated U.S. servicemen from around the Pacific.
She conducted four Magic Carpet runs, before heading to San Pedro, where she was released from the Magic Carpet fleet.
She departed Southern California on 4 February 1946, bound for Puget Sound, and upon arriving on 15 February, she underwent inactivation.
The ship was decommissioned on 17 January 1947, and mothballed as part of the Pacific Reserve Fleet.
Whilst mothballed, she was redesignated as a utility aircraft carrier, CVU-97, on 12 June 1955.
The hull was then once again redesignated, this time as an aircraft transport, AKV-33, on 7 May 1959.
Finally, her hull struck from the Navy list on 1 April 1960, and sold sometime in July 1960 to Eisenberg & Co. of New York for scrapping.
Her ultimate fate was to be broken up in Japan during November 1960.
