Early FBMs had three periscopes, A 2F type attack scope, an 8B observation scope and a Type 11 sextant scope.

Did any other submarines in the US submarine force have three periscopes?  If so, what was the first to have three scopes?

Triton SSRN-586 .......#1 scope was a navigation sextant scope ,but so far I can't find out if it had two more pericopes, or just one more.
Finns may have faults,but being wrong isn't one of them.

There were other submarines that had three.  So that is part of the answer.  Now which was first.  Not Triton.  Nice try.

USS S-8 (SS-113) had three periscopes. #2 scope was an alti-periscope. 


After further research, it looks to me that ALL S-Class had three scopes.

You are getting closer.  Not all S boats had three but most did at least when built.  Keep going.

The boats with three periscopes were of the S-3 (The 'Government Design') Class and the R-Class.  The R-Class was the last of the 'split classes' which were divided between Electric Boat and Lake Torpedo Boat.  The EB R boats carried three periscopes as did the S-3 Class.  The R-1 was commissioned in December of 1918 while the S-3 was commissioned in January of 1919.  Thus, the R class were the first with three periscopes as standard equipment. 

But only by a little bit.

In this close-up we see the conning tower fairwaters in more detail. Also,it would be noted that each of the three submarines has four masts raised, three of which are periscopes, and one telescoping radio mast.

This is from the "http://pigboats.com"    O-Class site. 

Is the fourth mast something else???

The dark 3rd mast aft (of 4) appears to be a radio antenna mast/flag hoist.
