USS Sage (AM-111) was an Auk-class minesweeper acquired by the United States Navy for the dangerous task of removing naval mines.

On 11 February, she and three other AMs tracked and attacked a possible submarine one mile off Gea, but the depth charges they dropped seemingly inflicted little or no damage.

On the 15th, however, she sailed with Task Group 51.11 for Eniwetok; and, the same day, joined the destroyers Phelps (DD-360) and Macdonough (DD-351) in sinking the Japanese submarine RO-40.

Arriving on 7 May, she underwent overhaul at Alameda, California; resumed escort duty on 11 June; and, by mid-August, had completed several runs between the Hawaiian and Marshall Islands.

On the 17th, her division left the formation and, despite high winds, frequent squalls, and reduced visibility, commenced sweeping operations at the entrance to Leyte Gulf.

At 0207 on the 20th, the minesweepers began maneuvering to avoid the main body of the assault force as it entered the gulf and, soon after 0630, they resumed mine disposal activities.

On the 24th, intensified enemy air activity opened the multi-phased Battle for Leyte Gulf, and Sage was ordered to make smoke to cover smaller vessels in her area.

On the 19th, she assumed antisubmarine patrol duties between Homonhon and Manicani, where a party from the ship provided the first medical assistance to the inhabitants in over three years.

Later in the day, as the troops moved off the beaches and secured their objectives, she got underway to return to Leyte, where she prepared for her next invasion, Lingayen Gulf, on Luzon.

On 4 February, Sage departed Subic Bay; returned briefly to Leyte; then sailed east to Guam; whence she set a course for Ulithi where she staged for Operation Iceberg, the invasion of the Ryukyus.

On 31 March and 1 April, she replenished at Kerama Retto; then, got underway to support the main assault force as it went ashore on Okinawa's Hagushi beaches.

After stops at Saipan and Guam, she got underway for Ulithi, whence she escorted a reinforcement and resupply convoy to the Ryukyus, where she resumed sweeping operations on 4 July.

On 6 August, she got underway again; escorted a convoy back to Leyte; and remained in San Pedro Bay until after the cessation of hostilities in the Pacific.

On 5 September, she moved north, to the Japanese home islands, and began clearing minefields and planting navigational aids in waters off Shikoku.

Ordered to the U.S. East Coast of the United States, Sage transited the Panama Canal in February 1946; and, in early March, she arrived at Charleston, South Carolina, for overhaul.

Recommissioned on 16 March 1951, she was homeported at Charleston; and, for the next three years, conducted training exercises off the southeastern seaboard, in the Caribbean, and in the Gulf of Mexico.

Reclassified MSF-111 on 7 February 1955, Sage departed Charleston ten days later; and, on the 18th, arrived at Green Cove Springs, Florida, where she was decommissioned on 19 April 1955 and shifted to the Orange, Texas, berthing area.
