The Tacoma class was a class of 96 patrol frigates which served in the United States Navy during World War II and the Korean War.

The class is named for its lead ship, Tacoma, a Maritime Commission (MARCOM) S2-S2-AQ1 design, which in turn was named for the city of Tacoma, Washington. Twenty-one ships were transferred to the British Royal Navy, in which they were known as Colony-class frigates, and twenty-eight ships were transferred under Lend-Lease to the Soviet Navy, where they were designated as storozhevoi korabl, during World War II. All Tacoma-class ships in US service during World War II were manned by United States Coast Guard crews.

When the United States entered World War II at the end of 1941, the United States Navy found itself deficient in ocean escort-type vessels. A crash building program was instituted; but, to meet more immediate needs, the government contracted with shipbuilding firms in England and Canada to build Flower-class corvettes. Vim (PG-99) was one of those British-type escorts. She was launched on 1 April 1943 at the Collingwood Shipyard in Collingwood, Ontario. Nine days later, however, she was transferred to the Royal Navy under the terms of the lend-lease agreement in return for another Flower-class corvette then under construction in Canada. The British renamed her HMS Statice, and she served the Royal Navy under the name through World War II. On 21 June 1946, she was returned to the United States Navy. Though carried on the Navy list as PG-99, the corvette never saw active service with the United States Navy. She was sold on 7 May 1947. To whom she was sold and to what purpose she was put is unknown.
