In a tiny patch of grass off Naval Avenue in Bremerton stands the upright black sail of the USS Parche, the only surviving piece of one of the most secretive submarines in the US fleet. The sail — the fin-like structure that rises out of the hull — is mounted beside a plaque, a flagpole and a single bench; you can walk around it, lean against it, read the dedication. Total visit time, fifteen minutes.
It is a strangely affecting little memorial, more interesting once you know the story. Combine with the Naval Undersea Museum in Keyport up the road for the full Cold War undersea picture.
