USS Moccasin (ID-1322)

USS Moccasin (ID-1322) was a United States Navy refrigerated cargo ship in commission from 1918-1919. She was the third ship to carryher name.

Moccasin was built as the German commercial passenger-cargo ship SS Prinz Joachim in 1903 at Flensburg, Germany, by Flensburger Schiffbau-Gesellschaft for the Hamburg America Line. When the United States entered World War I on the side of the Allied in April 1917, the United States Government seized her and placed her under the control of the United States Shipping Board for use during World War I. Renamed SS Moccasin, she entered service as an American civilian cargo ship. Late in 1917, the United States Army chartered her.

The U.S. Navy acquired Moccasin at New York City on 19 February 1918 for World War I use as a refrigerated cargo ship. She was assigned the naval registry Identification Number (Id. No.) 1322 and commissioned as USS Moccasin on 26 February 1918.

Service history
Assigned to the Naval Overseas Transportation Service, Moccasin departed New York City on 14 March 1918 with a convoy for Europe, arriving at Bordeaux, France on 13 April to unload her cargo of frozen food.

Moccasin continued to operate as a refrigerator ship, making cross‑Atlantic runs to Europe from New York, until she decommissioned on 2 June 1919. She was transferred to the United States Shipping Board the same day.

She returned to commercial service as SS Moccasin, later in her career being renamed SS Porto Rico.
