As far as we know of anyway...

Deep submergence vessel NR-1

https://en.wikipedia.org/wiki/American_submarine_NR-1

The vessel was casually known as "Nerwin" and was never officially named or commissioned. The U.S. Navy is allocated a specific number of warships by the U.S. Congress. Admiral Hyman Rickover avoided using one of those allocations, and he also wanted to avoid the oversight that a warship receives from various bureaus.

Through the 1970s and 1980s, NR-1 conducted numerous classified missions involving recovery of objects from the floor of the deep sea. These missions remain classified and few details have been made public. One publicly acknowledged mission in 1976 was to recover parts of an F-14 that was lost from the deck of an aircraft carrier and sank with at least one AIM-54A Phoenix air-to-air missile. The secrecy typical of USN submarine operations was heightened by Rickover's personal involvement, and he shared details of NR-1 operations only on a need-to-know basis. Rickover envisioned building a small fleet of NR-1 type submarines, but only one was built due to budget restrictions.

Following the loss of the Space Shuttle Challenger in 1986, NR-1 was used to search for, identify, and recover critical parts of the Challenger craft. It could remain on the sea floor without resurfacing frequently, and was a major tool for searching deep waters.

Name: NR-1
Builder: General Dynamics Electric Boat
In service: 27 October 1969
Out of service: 21 November 2008
Displacement: 400 tons
Complement: 3 officers, 8 crewmen, 2 "scientists"
(quotes are mine; my guess would be that they'd be better called "mission specialists" for any classified mission)

The recent article that brought the existence of this sub to my attention:
