USS Avocet (AM-19/AVP-4) was a Lapwing-class minesweeper initially acquired by the U.S. Navy for the dangerous task of removing mines from minefields laid in the water to prevent ships from passing. Avocet was commissioned at the Norfolk Navy Yard, on 17 September 1918, as a minesweeper with Lieutenant Christian Crone in command. Recommissioned on 8 September 1925 as a small seaplane tender, USS Avocet (AVP-4) was present during the Pearl Harbor attack on 7 December 1941. The ship survived the war, and was sold as a hulk on 6 December 1946.
