USS Cimarron (AO-22) was a Cimarron -class oiler serving with the United States Navy and the second ship
to be named for the Cimarron River in the Southwestern United States. She was launched 7 January 1939 by
Sun Shipbuilding and Drydock Company, Chester, Pennsylvania; sponsored by Mrs. William D. Leahy; and
commissioned 20 March 1939 with Lieutenant Commander William W. Behrens, Sr. in command.

Cimarron cleared Houston 31 May 1939 for Pearl Harbor, arriving 21 July. She transported oil between west
coast ports and Pearl Harbor, making 13 such voyages until she sailed for the east coast on 19 August 1940.
After repairs and alterations, she began oil runs on the east coast, principally between Baton Rouge and Norfolk,
until August 1941, when she took part in amphibious operations. From 5-16 September she put to sea with a transport
convoy bound for Iceland, and voyaged north again from 12 October to 5 November to refuel ships at Placentia Bay.
On 15 November 1941, she joined a convoy at Trinidad bound for Singapore with reinforcements, but was detached
from the convoy on 9 December at Cape Town, South Africa. Returning to Trinidad on 31 December, she operated
from Brazilian ports to Iceland until 4 March 1942, when she cleared Norfolk for San Francisco.

Cimarron departed Pearl Harbor 29 September 1943 with the force which raided Wake Island on 5-6 October, and
returned to Pearl Harbor 16 October. She sailed once again 14 November to fuel in support of the Gilbert Islands
campaign, returning 1 December, and sailed to San Pedro, California to reload 12 December to 4 January 1944.
Clearing Pearl Harbor 13 January 1944, she supported the Marshall Islands operation and the February attacks
on Truk from Majuro until 6 June; the Marianas operation from Eniwetok until 26 August;
and the Palau Islands operation from Ulithi
