Tonopah 701k New York Navy Yard on 4 November 1915. Waterfront, Looking Southeast from South Side of Pier F:
Two former monitors, converted to submarine tenders appear one behind the other. The Tonopah (M-8) is most likely the 1st ship & the Ozark (M-7) the other. Their charges are 4 K class submarines in camouflage; (in no particular order that can be determined here) K-1 (SS-32), K-2 (SS-33), K-5 (SS-36) & K-6 (SS-37). What appear to be 3 submarines are moored port side of the Ozark in the photo here.

68810981.16kNew York Navy Yard on 24 January 1916, 6 submarines in drydock.
G-4 (SS-26) is in the center. Stern planes configuration makes this definitely her. Cool thing - notice the two part hatch on the aft deck. It is a hatch/scuttle combination normally found on surface ships, but EXTREMELY rare on submarines. In fact I would say this is the first time that I have ever seen this on a USN boat. It is probably a feature of her original Italian Laurenti design.
The boat on the right is definitely the G-2 (SS-27). G-3 (SS-31) had a similar after superstructure, but by the date of the photo she had already received prominent blister saddle tanks on the side of the hull, and those are missing on this photo. Both boats were known to be in New York during the time of the photo.
I'd like to say that the left hand boat is a "K" boat just due to the fact there is some painted Camo in the top of the periscope shears. K-5 (SS-36) or K-6 (SS-37) maybe. The rest of the boats are the other K boats, K-1 (SS-32) & K-2 (SS-33).

K 696k There are fewer busier places in Philadelphia than the large drydock at the Philadelphia Navy Yard, where repairs are being made on eleven of Uncle Sam's submarine craft.
Among the boats visible is the K-1 (SS-32), which appears in the front left corner, and K-5 (SS-36), behind her. The remainder of the K-boats are likely here as well.

674kThe Sesqui-Centennial International Exposition of 1926 was a world's fair in Philadelphia, Pennsylvania. Its purpose was to celebrate the 150th anniversary of the signing of the United States Declaration of Independence, and the 50th anniversary of the 1876 Centennial Exposition. The fair opened on 31 May 1926.
Text of photo reads Sesqui-Centennial International Exposition, Philadelphia, PA. Docking 11 submarines, League Island Navy Yard.
It would be my guess that these boats are K-boats submarines. The date is most likely late 1924 after they had been towed to Philadelphia. K-6 (SS-37) and K-8 (SS-39) are the only two identifiable on the right. They had been decommissioned in Norfolk on 24 February 1923 and sat there for a while. They were all towed to Philadelphia in September 1924 until finally sold for scrap in 1931.
