Ibis was built as the commercial fishing trawler Sea Gull by the Globe Shipbuilding Company at Superior, Wisconsin, in 1917.

In June 1918, the U.S. Navy acquired her from her owner, the Atlantic Coast Fisheries Company of New York City, for use as a minesweeper during World War I.

Assigned to the 1st Naval District in northern New England, Ibis operated for the remainder of World War I and into 1919.

Satilla suffered considerable damage, with her hull buckled in on the port side and leaking, and was under repair for the next few months, not returning to duty until after the end of World War I.

[1] Ibis was decommissioned after the end of World War I and was returned to her owner on 3 March 1919.
