All of the V-boats, but especially the huge V-4, suffered from an underdeveloped diesel engine industrial base in the United States. The industry was still in its infancy in the U.S., and the Navy was forced to rely on license-built derivations of German MAN company designs.

Design, Construction, and Naming Notes
V-4 was a giant. At 381 feet long and a displacement of 3,046 tons submerged her size would not be exceeded by a USN submarine until the nuclear-powered USS Triton (SSRN-586) of 1955. Her great size was dictated by the need to achieve long range. Only a very large submarine would be able to carry the fuel necessary to span the Atlantic and Pacific in search of the enemy's merchantmen. V-4 was also to be equipped with the largest caliber gun ever installed on a USN submarine, two 6"/53 caliber Mk 17 guns, one forward and one aft of the conning tower fairwater in open mounts.
Her great range enabled V-4 to go to an enemy's coastline and lay an effective minefield. The minelaying gear was unique to the boat, and it occupied the after end. Space was provided for sixty huge Mk 11 mines and specialized, automatic, hydraulically operated handling gear. The mines were launched from two large aft facing tubes, and the mines could be laid while the boat was completely submerged. She also was equipped with four 21-inch torpedo tubes forward, with a capacity of 20 Mk 14 torpedoes.
All of the V-boats, but especially the huge V-4, suffered from an underdeveloped diesel engine industrial base in the United States. The industry was still in its infancy in the U.S., and the Navy was forced to rely on license-built derivations of German MAN company designs. The V-4 was definitely underpowered, with her plant consisting of two direct drive 1,400 hp BuEng/MAN main propulsion diesels, and one 450 hp BuEng/MAN generator engine. The Navy specified 15 knots for this boat, and she struggled to make that.

A number of interesting things are seen and happening in this photo. The launch is complete and the signal flags are coming down. The flags forward of the conning tower are being gathered up. The after string of flags is being loosened. A Bi-pod of boards supported the after string. A man has climbed to a cross brace to free them. A man stands behind him to steady him. A Chief or Officer is on the stern inspecting and ensuring that all is satisfactory.
The dark triangle seen between the tugs is the forward gun sponson. There is a similar one behind the conning tower hidden by the Mohave. The Mohave itself has just applied forward thrust to is propeller as evidenced by the wash seen at her stern. The white "splash" seen at the waterline at the side of Mohave is the outlet for the cooling water for the tugs' boiler.
The tug all the way to the left is taking charge of the building cradle seen floating next to it. A crew in a small boat is assisting.
