USS Mifflin

After shakedown, Mifflin embarked 1,100 troops and sailed to Pearl Harbor. Exchanging her initial passengers for members of the 4th Marine Division, she continued amphibious exercises off Maui, until ordered to Saipan 27 January 1945.[3]

On 19 February, her boats landed the[3] 2nd Battalion 23rd Marines and their Shore Party, B Co 133 NCB—4th Marine Division on beach "Yellow 2", Iwo Jima.[4] She remained almost a week to offload priority, then request cargo, and to take on board battle casualties. This included her own, for the ship's beach party was hard hit the first day suffering 14 wounded and three missing.[5] Mifflin also sustained a shell hit on her 40mm gun director before retiring with the wounded to Saipan on 28 February.[3]

Having replaced lost equipment and boats, she sailed 16 March, to nearby Tinian to practice for the invasion of Okinawa. In position for this last great assault, on 1 and 2 April, her boats feinted a landing of 2d Division Marines on the southeastern shore to lessen opposition to the main effort on the western beaches.[3]

Again returning her Marines to Saipan, she remained until early June. Steaming to the New Hebrides, Mifflin loaded stores which she discharged 30 June, at Guam. Independence Day, she weighed anchor for San Francisco with a small passenger list and a need for repairs.[3] Two months later, when she returned to the western Pacific to disembark 1,600 US Army replacement troops at Manila, Philippines, the war had ceased. Mifflin reloaded with men of the 33rd Infantry Division assigned to occupation duty and arrived Wakayama, Japan, 25 September. The next month, over 1,000 troops of the 24th Infantry Division were transported from Mindanao, Philippines, to Okajama, Japan. Sailing to Okinawa 30 October, she engaged in "Magic Carpet" duty from November to March 1946, returning additional thousands of veterans to San Francisco.[3]

Inactivation soon began with Mifflin placed out of service in reserve 5 July 1946, assigned to the 19th Fleet, Stockton, California. Struck from the Naval Register 1 October 1958, she was returned to MARCOM the same day. Assigned to the National Defense Reserve Fleet, she was berthed as Suisun Bay, California, into 1969.[3] She was sold under a "non-transportation use" (NTU) contract to West Waterway Lumber Company, 17 July 1975, for $128,009. She was transferred out of the fleet 6 August 1975.[6]
