Unusually, Electric Boat eliminated the bulkheads that made the control room a separate space, reverting back to the concept of having the forward battery, control room, and after battery one large space.

There is some debate about which organization actually built the K-4. The Moran Company in Seattle was going through significant organizational changes during this period, and came out of this process called the Seattle Construction & Dry Dock Company. It is likely that the construction contract was signed by Moran Company representatives, but the actual construction was handled by SC&DD.

<div style="text-align: justify;"><span style="color:#00008B">K-3 is shown here on her builder's trials, September 1914, possibly in or near San Francisco Bay. Note the two civilians on her forward deck. These would be yard workers from the Union Iron Works yard that built her.
Note the vertical number "24" on the side of the periscope shears. This is not her hull number. It was an identifier used to determine the boat's place in a steaming formation at sea, i.e. she was the fourth boat of division 2.
Her periscopes are fixed in height and do not retract. The eyepiece down in the control room does not move either. It is fixed in place and the operator cranks a handwheel to rotate the head on top with the lens.</span>

<div style="text-align: justify;"><span style="color:#00008B">This picture is most likely taken on Sinclair Inlet near the Puget Sound Navy Yard circa early 1914 showing the submarine K-4 enroute back to Seattle. At this time there were no marine fueling stations in Seattle dispensing diesel oil. On closer examination a commissioning pennant can not be seen so this is probably prior to her commissioning on October 24, 1914.
The two ships in the background are the receiving ship USS Philadelphia (rear) and the Charleston (Cruiser No. 22). The Philadelphia was serving as a prison ship and had wooden structures built on her decks to accommodate extra berthing for personnel and offices for administrative purposes.
If you look at the Charleston's funnels and number from left to right, between the 3rd and 4th funnel you can see the flag staff with flag flying from the stern of the Philadelphia.
Charleston had been placed in commission in reserve September 14, 1912, she joined the Pacific Reserve Fleet, remaining at Puget Sound (Bremerton) Navy Yard as a receiving ship through early 1916, aside from a voyage to San Francisco in October 1913 as flagship for the Commander-in-Chief, Pacific Reserve Fleet. From 1912 through early 1916, she was receiving ship at the yard.</span>
