R-7

R-7 approaching the finger piers at Submarine Base Pearl Harbor, approximately 1925. Note the extent to which the main deck had to be flared outward to form a sponson for the deck gun. The gun itself is elevated upward.

This and the next four photos are of the R-7's crew and were taken at Pearl Harbor in 1925. The commanding officer, LTjg Robert Andrew Knapp, is shown in the center front. The R-2 is moored on the right side of the photo.

The R-7's enlisted crew are lined up on the main deck behind the gun, and the officers are shown on the bridge. Pearl Harbor, 1925. Sister boats R-2 (SS-79) and R-10 (SS-87) are moored alongside.

The center closeup of the photo above. This also gives good details of the 3"/50 caliber Mk 6 gun that was carried by the R-class boats. For more information on this gun, see the link here and this link to the NavWeaps.com page.

The right side of the crew photo. Strangely, this photo shows only one Chief Petty Officer. These boats were billeted for three to four CPOs. Why there is only one shown here is unknown.

The final closeup of the crew photo, showing the officers on the bridge. The CO, LTjg Robert Knapp, is in the center. Normally these boats would have been commanded by a full Lieutenant. The Pacific Fleet submarine force may have been experiencing some personnel shortages at the time which forced the squadron to assign a LTjg as CO, or Knapp may have been selected for LT but had not yet been advanced. The exact situation is not known.

A series of photos gifted to Ric Hedman that show R-7 and her crew at sea off Hawaii for a training cruise in 1925. The weather was uncharacteristically rough (or "ruff" as described by the photographer) with water breaking over the deck. It is actually unusual for the CO to let his crew up on deck under these conditions. It was not safe.

R-7 crew members McLaurin & Hively at Submarine Base Pearl Harbor, 1925. They are topside standing near the aft end of the conning tower fairwater. Note the configuration of the air whistle at the top of the shears, above their heads.

Gunnery practice off Hawaii, 1925. This photo was taken from the bridge.

It was not uncommon for the crew to try to supplement their diet with fresh fish. Also at time it was just a recreational activity. Here two R-7 sailors proudly display their day's catch. Photo taken off Hawaii in 1925.

R-7 crew photo taken at Pearl Harbor, approximately 1926. The R-1 (SS-78) is moored in the background. There are two officers, one Chief Petty Officer (to the right of the officers), and 27 crew shown here.

Pearl Harbor, circa 1929-30. According to the photo caption in the scrapbook the R-7 is undergoing a dockside upkeep in this photo. There is a man standing, half hidden, in front of the conning tower. He must be standing on the back of the deck gun to be at that height. One foot appears to be resting on the lifeline. R-7 appears to be painted black in this photo, well ahead of the Navy's mandate to repaint all submarines black in 1934-35. It is known that the command in Hawaii was experimenting with different paint schemes in the early 1930's, as it became apparent during tests with aircraft that the haze gray painted boats were still very visible at periscope depth in the clear Hawaiian waters. Apparently, several different colors were tried, including dark blues and even several shades of dark green. So it is possible that the color shown here is not black, but there is no way of knowing this in a black and white photo.

R-7 in a refit period at Pearl Harbor, approximately 1930. Some of the crew are posing for the camera while chipping paint. There appears to be a destroyer in the dry dock with her. Looks like they are preparing to remove the bow planes hinge cover, it has "R 7 Port" written on it in chalk. They have yet to chip the paint from the lower bow, also they seem to be avoiding the draft marks. Chipping paint was an extremely tedious but very necessary process during a submarine overhaul. Chipping away the old paint revealed corrosion problems that could be addressed before new paint was applied.

Another view of the R-7 in dry dock approximately 1930 showing the bow with towing fairlead (aka "bullnose") on the far left and open torpedo tube shutter doors below. The bow planes fairing cover shows the "R 7 Port" marking. A crew member is in the bottom of the dry dock. He probably has the messy job of chipping paint from the mushroom anchor seen hanging from the bottom of the sub on the right side of the photo.

The crew of the R-7 in the late 1920's and early 1930's were apparently quite the fishermen. Here they are gathered around on the aft deck with their latest catch, a rather large mahi-mahi, commonly known as a dolphinfish, the symbol of the Submarine Service. It appears that one of the Asian Mess Attendants is examining the catch. The rest of the crew look on. On the back of the submarine can be seen two large "pipes". This is the normal storage location for the torpedo loading King Post, (right) and Boom, (Left).
