S-9 731k All the boats in the image are S-boats.
On the left is the S-9 (SS-114). The next is probably S-24 (SS-129). All of the rest are 20 series boats. The boat in the background IS NOT the S-2 (SS-106). It is a 20 series like the others. The last digit in the boat's name is obscured by the torpedo davit on the boat in the middle.
As for a location, the pier in the background looks like some images I have seen of San Pedro, California. Although the fact that this came from the New York Daily News Archive seems to indicate the Brooklyn Navy Yard or some location in the city.
I can't see the stern of any of the boats. This helps in dating the photo. It appears that the aft skeg of the S-24 is still in place and there are no post S-4 (SS-109) safety modifications so this would indicate that the photo was taken in the mid to late 1920's, but this is only a rough guess.

S-21 74k The Presidential review off the Atlantic coast saw a number of boats underway.

refleting 140k S-boats top and bottom as in a refleting pool, probably at Pearl Harbor when they operated with Division 7, circa 1931-33. S-21 (SS-126), S-22 (SS-127), S-23 (SS-128) & what was thought to be S-24 (SS-129).
On 25 April 1931, S-22 & S-23 arrived together at Pearl Harbor.
If you look closely at the outboard one (on the far left) the fairings that cover the bow plane pivots are rounded. On the other boats in this photo these fairings are angular in shape. The angular fairings are a distinctive characteristic of the Quincy built 20 series S-boats (S-18) to (29). For the Union Iron Works built boats (S-30) to (41) this fairing is rounded and smaller in size. The only exception to this rule is the (S-19). She alone amongst the Quincy boats had the rounded fairings of the UIW boats (why I donít know yet). Therefore, the outboard boat in this photo can not be the (S-24). It has to be (S-19) or (30) to (41).
