USS Scamp (SSN 588) on the surface.
The tall mast is a high frequency radio antenna; the lower one is a type 15 periscope, behind which is another I don't recognize. I'm surprised we don't see a small surface search radar antenna since the boat is surfaced.
Scamp was one of the relatively early Skipjack class boats; known for being fast but relatively noisy. She was decommissioned in 1988. Her sister boat the USS Scorpion (SSN 589) was lost with all hands (99 men) in May of 1968.
