My father was an ME and EE and was one of the principle engineers on that project (of Clementine, the BIG claw that picked up the Russian Golf Class sub).

I used to drive him to and from the Redwood City shipyard as there wasn't a lot of parking there.

He also gave me 9 or 10 manganese nodules from the "test" mining run, which was the CIA cover story.

They look like fist sized black to gray cauliflower heads.

After the project was declassified he got a Presidential Commendation, which he framed and hung over the kitchen table.
