ALVIN is a submarine built in
1963. It made several discoveries, and was also used in
1966 to recover a lost american
H-bomb near the
Spanish coast. It made more than 3,800 dives, and is still in use. The name ALVIN was created both from
Allyn Vine[?], the head behind its construction, as well as the popular cartoon character,
Alvin the Chipmunk[?].
