Submarine Relics: The Fin Project
Seattle, Washington
Unveiled in 1998, "The Fin Project" is made out of 22 diving-plane fins from the Puget Sound Naval Shipyard, salvaged from decommissioned 1960s Navy nuclear submarines. The pieces are mounted upright into the ground of a park, like the fins of a pod of Puget Sound Orca whales or a school of Washington state salmon.
A well-worn dedication plaque from artist John T. Young states that the purpose of The Fin Project was to promote peace, turning weapons into art, and recycling. Back in 1998 a plaque on each fin identified the sub that it came from, but some or all of those those plaques may be missing now.
The Fin Project proved so popular (and decommissioned nuclear submarines so plentiful) that Young built a second version in Florida, even though that state has no Orcas or salmon.
