USS Forster (DE-334) was an Edsall-class destroyer escort built for the U.S. Navy during World War II.

Forster was commissioned 25 January 1944 and served as an escort in the Atlantic and Mediterranean during World War II.

She was stationed out of Pearl Harbor in the 1960s and served in the Western Pacific on Operation Market Time in 1968-69 patrolling the South Vietnamese coast for contraband shipping and providing sea to shore fire when called upon.

In February 1966, Forster escorted the nine cutters comprising Division 13 of Coast Guard Squadron One from Naval Base Subic Bay to Vung Tau in South Vietnam.

The Vietnam People's Navy renamed her VPNS Dai Ky (HQ-03), she was apparently still seaworthy in 1997 and was used as a training ship.
