Dolphin VI

(SS-169: dp. 1,560; 1. 319'1", b. 27'11", dr. 13'1"; s. 17
k.; cpl. 57; a. 1 4", 6 21" tt.; cl. Dolphin)

The sixth Dolphin (SS-169) bore the name V-7 and the classfication SF-10 and SSC-3 prior to her commissioning. She was launched 6 March 1932 by Portsmouth Navy Yard; sponsored by Mrs. E. D. Toland; and commissioned 1 June 1932, Lieutenant J. B. Griggs in command.

Dolphin sailed from Portsmouth 24 October 1932 for San Diego arriving 3 December to report to Submarine Division 12. She served on the west coast, taking part in tactical exercises and test torpedo firings until 4 March 1933 when she gut underway for the east coast. She arrived at Portsmouth Navy Yard 23 March for final trials and acceptance, remaining there until 1 August.

Dolphin returned to San Diego 25 August 1933 to rejoin Submarine Division 12. She cruised on the west coast with occasional voyages to Pearl Harbor, Alaska, and the Canal Zone for exercises and fleet problems. On 1 December 1937 Dolphin departed San Diego for her new home port, Pearl Harbor, arriving a week later. She continued to operate in fleet problems and training exercises, visiting the west coast on a cruise from 29 September to 25 October 1940. At Pearl Harbor on 7 December 1941, Dolphin took the attacking enemy planes under fire, then got underway for a patrol in search of Japanese submarines in the Hawaiians.

Dolphin departed Pearl Harbor 24 December 1941 on her first war patrol, during which she reconnoitered in the Marshall Islands in preparation for later air strikes. She returned to Pearl Harbor 3 February 1942 to refit and make repairs, and got underway once more 14 May. Searching a wide area west of Midway, she patrolled off the island itself during the critical Battle of Midway from 3 to 6 June. She put in to the island, saved by the American victory in battle, for repairs from 8 to 11 June, then returned to her patrol, attacking a destroyer and a tanker with undetermined results before returning to Pearl Harbor 24 July.

Her third war patrol, from 12 October 1942 to 5 December, was in the storm-tossed waters of the Kurile Islands, where she performed reconnaissance essential to the operations which were to keep Japanese bases there largely ineffective throughout the war. With younger submarines now available for offensive war patrols, Dolphin was assigned less dramatic but still vital service on training duty at Pearl Harbor until 29 January 1944, when she sailed for exercises in the Canal Zone, and duty as a schoolship at New London where she arrived 6 March. She served in this essential task until the end of the war, then was decommissioned 12 October 1945 at Portsmouth Navy Yard. Dolphin was sold 26 August 1946.

The second of Dolphin's three war patrols was designated as "successful," and she received two battle stars for World War II service.

Dolphin SS-169 - History

USS Dolphin SS 169 (ex-V-7) Interior Photos

These interior photos (and many of the exterior photos) of the USS Dolphin SS-169 (formerly V-7) were offered to PigBoats.COM by a Naval Researcher named Roger Torgeson who acquired them during a visit to the National Archives "a while back".

In his words: "I may have some recently scanned photos from the National Archives you might be interested in. One of my finds was a box of images of the USS Dolphin V-7, SS-169 which appear to be the builders album of photos which the 5th floor staff were kind enough to disassemble so I could make scans, the total number of scans I have come to 76 both interior and exterior."

The results of those scans are presented here as a PigBoats.COM exclusive. The photos, along with many close ups showing interesting portions of the larger photos, make up this extensive tour of the USS Dolphin SS-169, popularly known to the public at the time as "Submarine D1"!

Several months of intensive research has gone into developing the captions and background information for these pages. Submarine technology has changed tremendously between the Dolphin's era and the time Dave and Ric were in the Submarine Navy in the 60's, 70's and 80's. With all of the Dolphin's crew and the men who designed and built her long gone much of her technology has been "forgotten" and it took the accumulated experience of the two of us, assisted by several other submarine veterans to decipher and interpret the machinery and features in the photos. With all of that, many features remain open to further research, and in some cases we were forced to speculate. If anyone can correct or update any of the information presented here we would welcome your assistance and you will be given full credit for your contributions.

Dolphin was a transitional submarine. The Navy, in its attempt to create a long range submarine to operate with the fleet, was pushing the boundaries of the technology of the day. The previous classes up through the S-class were harbor defense and coastal patrol designs and did not have the speed, range, or reliability needed to cruise with the Battle Fleet and operate as the eyes of the Navy. The first attempt was the short lived "M-1", a one boat class followed by the three T-class, these ultimately proved to be failures because the knowledge base and the manufacturing state of the art were not sufficient to provide those robust qualities, and with diesel engine technology still in its' infancy they did not have the necessary power and speed.

The follow-on V-class (of which Dolphin was a member) was an attempt to correct these issues. The first six boats were giants (compared to earlier classes) and while they had the requisite range they still suffered from many of the same problems that plagued the M and T-class.

Dolphin (originally named V-7, her name was changed before she was launched) was an attempt to reign in this trend in gigantism. With rearranged interiors, better handling, and better engines the designers had unintentionally hit upon the nearly optimum combination of qualities that would lead nearly 10 years later to the war winning Gato, Balao, and Tench class boats.

The intention to build more of the Dolphin version of the V-class was never carried out because limitations imposed by the London Treaty of 1930 made her still too large. The result was the construction of the last two of the authorized "V" class submarines, the smaller, lighter Cachalot SS-170 and Cuttlefish SS-171 at 1200 tons, versus the Dolphin at 1700 tons.

We hope that further clarification on the pictures and captions will come in the next few months as a research group is traveling to the National Archives this fall. In the mean time captions may change as discoveries and better information is found. The hope for this trip is the possible discovery of more photos and blueprints/line drawings that will help us refine the information found here.

Dolphin SS-169 - History

The USS Dolphin Interior Diagram. The photos in the following sequences begin at the right and work their way to the left or aft. The Torpedo Rooms are unmarked as they are pretty self explanatory.

This is the Dolphin's forward Torpedo Room under construction. At the forward end of the compartment are the openings for four of her six torpedo tubes (the other two are in the stern). The tubes themselves have not yet been installed. Views of the shipyard are visible through the openings.

It is noted by the light seen between the frames that the hull plating has yet to be completed.

Dolphin has been reported in several authoritative history texts has having been of fully riveted construction. Yet, in the lower left-hand corner of this photo welding beads can be seen where the I-beam frames meet the deck (actually the top of the forward trim tank). There is also a line of rivets running port to starboard along the top of the deck.

This photo, along with photos 015 and 016 on the Dolphin Exterior Photos page are proof positive that this boat was built to a partial-riveted/partial welded construction method, over a year prior to the start of construction of the USS Cuttlefish (SS-171) at Electric Boat. The Cuttlefish is incorrectly believed to be the first welded submarine by most historians.

This is the Dolphin's forward Torpedo Room just shy of 13 months later, still under construction. At the forward end of the compartment the four torpedo tubes have been installed and mostly plumbed. Equipment is being installed and the room is nearing completion. The large brackets installed on the frames are to hold the MK14 torpedo weighing 3300 pounds. Dolphin was designed to carry 18 of these weapons.

Dolphin's forward escape trunk can be seen above where the planks cross. The angled ladder leading to the trunk is seen leading into the trunk. In the upper left a large rod is seen. This is the mechanical linkage for the bow planes that runs back to the control wheel in the control room.

This is the Dolphin's Generator Room, the next compartment aft of the After Battery. The starboard generator engine has been installed and the view is looking forward. The forward walking deck has not been completed and the sheet metal sides of the storerooms around the galley and Chief's dining area can be seen.

One more engine will be installed, and this will be lowered into the space via an opening in the hull above the wood ladder. Engineering spaces had what is called a "soft patch" in the hull that was bolted to the pressure hull to allow large pieces of equipment to be removed, repaired or replaced without needless cutting into the hull.

The USS Dolphin interior photo of the Forward Torpedo Room. The view shows the forward half of the room including the four Torpedo Tubes and operating valves.

The image was taken 13 months after the submarine had been commissioned. There are no torpedoes loaded at the time the picture was taken as she was at the Portsmouth Naval Shipyard from March 23, 1933 for final trials and acceptance and remaining there until August 1, 1933.

The ventilation ducting in the overhead splits around the Torpedo Room Deck Hatch. A ladder would attach to the forward side of the hatch. In this photo the ladder is laying on the top torpedo rack on the left or Port side of the room.

Close up of the torpedo tube doors on the USS Dolphin. The torpedo support stanchions in front of the tubes appear to be non-removable. On close analysis of the bases of these there appear to be bolts holding frames to the deck.

The appearance that they look like they interfere with loading the lower tubes we think is a trick of angle with the camera. We believe the fore shortening effect of the camera makes them seem closer to the tubes and doors than they really are.

The curved lockers on the port side are unusual. We have not seen lockers shaped like this before.

If you look at the hull shape surrounding the tube doors you can see that the Navy was still building elliptical hull shapes. The hull is taller than it is wide.

The USS Dolphin Forward Torpedo Room looking aft. Bunks and torpedo storage racks can be seen to each side. There would be storage for 12 torpedoes here. That means one in each tube and two reloads for each tube.

Note the torpedo loading hatch in the overhead just aft of the screened in enclosure. The wheel and the electronics on the aft bulkhead are for the Q series sonar heads with the periscope looking shaft used to lower the heads below the keel for use.

To the left is a small room. At this time we have no idea what this was for. Above is a small work area with a bench and vice plus a large electrical cabinet.

We call this the "Mystery Room". More research will probably tell us what this space was used for but until then this is the Mystery Room. It has a well used sliding door that has made scrape marks on the metal bulkhead and has an upper and lower ventilations screens at the inboard end. Part of a dial can be seen through the upper one. The overhead of the room forms a mezzanine with a large electrical cabinet and work bench with a vice. What was it used for? Unknown at this point.

This is looking up at the bottom of the Torpedo Room Escape Hatch of the USS Dolphin. The bottom hatch seems to oval in shape and offset at an angle. To the left are the Torpedo Tubes and the Bow. To the right is aft. The glare coming down the hatch makes it hard to see any detail of the Escape Trunk itself.

Looking aft at the Dolphin Ward Room. The ward room is "Officers Country" where they ate, hung out and socialized. The chairs are of a folding type and have leather backs and seats. A chair of the same type can be seen in the Captains stateroom.

A counter is at the left that held dishes, linens and silver service such as serving bowls and platters and knives and forks. An electric coffee pot sits on the counter with a coffee cup on top that is turned up side down, in Navy parlance, meaning there is no coffee.

Seen stowed in the overhead are a number of rifles and sub machine guns.

A storage unit on the the hull has cubbies for each officer for his paperwork.

A closer look at the guns stored in brackets in the overhead. Visible are three Thompson Sub Machine Guns. The part hanging down are the hand grips. Also seen are the butts of what are probably two M1903, 30-06 caliber Springfield Rifles. This rifle was known as the "United States Rifle" and was in general use in the military up into the early years of WW II when it was replaced by the M1 Garand.

A close up of the counter that held dishes, linens and silver service such as serving bowls and platters and knives and forks. An electric coffee pot sits on the counter with a coffee cup on top that is turned up side down, in Navy parlance, meaning there is no coffee. For the record, the fan is spinning as the photo was taken.

The Ward Room of USS Dolphin. If we are understanding the seating arrangements correctly, it seems to be turned 90 degrees to conventional. Seating as we have understood it the Captain sits at the "head" of the table which on US submarines was the after end of the table. and in descending order of rank the other officers. Here it seems to indicate that the Captain sat at the inboard end of the table and the other officers sat on the fore and aft sides. Not sure if that was followed in any later classes of submarines.

This close up of the library shows a collection of popular reading material and technical books. A closer look shows only a few books titles can actually be read. The box on the right bulkhead is probably a radio receiver.

The Chelsea clock shows that this photo was taken at ten fifty eight in the morning on July 3, 1933. Chelsea Clocks are one of the most accurate marine clocks in the world.

Books on the book shelf. A number of titles can be made out but overall the resolution isn't good enough to read them all.

One of the titles is: "The Case of the April Fools" published in 1933 by Christopher Bush. Part of a mystery novel series. Another is: "The Ear in the Wall" by Arthur B. Reeve. The last one we can read the title of is "The Hawk(s) Eye" but we can find no information on it.

The Captains Stateroom. This is the only officers stateroom we have a photo of. There were probably two or maybe three more. The Captains stateroom was directly aft of the Ward Room and aft of that was the Radio Room on the port side. More staterooms for Junior Officers were on the starboard side, there were probably two rooms with bunks for two or three officers. Aft of those may have been the ships office, a fore shadowing of what was to be the conventional layout for submarines for the next twenty years.

A view looking aft in the Captains stateroom. A large bunk with a fine wood bunk frame and a spare upper bunk above for a high ranking guest are seen on the right or port side of the room. The Captains desk is against the after bulkhead.

Commanding Officer Lieutenant John B Griggs Jr. as seen in a news paper photograph.

The forward Battery well of the Dolphin showing the arrangement of batteries and the battery cell ventilation system piping identified by Submarine Historian Jim Christley. At the left a two wire extension cord is seen, probably used for the lights for lighting the space for this photo.

The forward Battery well of the Dolphin looking aft showing the arrangement of battery cell ventilation system piping as well as at the aft end of the space are the main battery disconnects that isolated the battery from the rest of the electrical bus.

Aft of the Captains stateroom is the Dolphins Radio Room.

The following quotes are from Jon Krup who served in the Navy in early 1960's. He has these speculations on what we see here ". the three pieces of equipment [above the desk] appear to be radio receivers.

"Above them and to the left (above the loudspeaker), are what appear to be drawers. They are the necessary electronics to change frequency bands on the receivers. Pull one out and install in the radio and you are on the 10 MHz band. Another would put you on the 15 MHZ band, etc. The transmitters are out of the frame to the right. They appear to be either RCA, Collins or possibly Westinghouse receivers, more than likely Collins. Definitely tube type."

"The drawers contained capacitors, coils (tuned circuits) and crystals specifically cut for a certain frequency band. There is in the upper right of the panels, a tuning dial - either a moving paper, or a rotating card, back lit, with multiple number scales, coordinated with the (I'm going to call them ) tuning drawers. Put in drawer #1 and use scale #1 to go with it, etc."

The USS Dolphin Radio Room looking aft

The following quotes are from Jon Krup who served in the Navy in early 1960's. "This is definitely the transmitter, more than likely specially designed for submarines. Note that it doesn't "go back into the wall" very far.

I see no tuner dial on it, so I have to assume it is crystal controlled. There would be a small box containing crystals especially cut for the frequencies that submarines would use/be authorized to use. The radioman could change crystals depending on their location, time of day, and the atmospheric conditions. By atmospheric conditions, I don't mean weather, but what's happening up in the ionosphere. This could include the proximity of lightning, sun spots and the aurora. These frequencies would be set by the operational orders of that particular boat, and is coordinated with COMSUBLANT and COMSUBPAC.

"The transmitter appears to be made by MCA, according to a plaque on the lower left corner, behind the chair. I can't quite make it out, but will, again, nose around the internet.

"Note that they would only operate with Morse code. Voice transmissions were probably not permitted at that time, nor were they able with this transmitter. To talk ship to ship would be in Morse code until the boats got close enough to holler across the distance with megaphones."

Further research has indicated that Dolphin had voice capabilities

The USS Dolphin Radio Room looking outboard to port. Chairs are of a different type than seen in the Ward Room. Between the chairs down almost at deck level we see another of the manual Ballast Tank Flood Valve handles.

The primary gyrocompass is the black barrel shaped object just inside the door. The black box directly aft and next to the helm I believe to be the gyrocompass repeater that took inputs from the gyro and indicated the course you were steering.

In the center above the helm wheel is the rudder angle indicator, flanked on both sides by the engine order telegraphs. The lever on the vertical shaft was used to engage/disengage the control room helm from the conning tower and bridge helm.

Which helm would have been the primary station for submerged operations? I would lean towards the conning tower, but that opinion might be flavored by what was done in combat in WWII and may not necessarily reflect pre-war 1930's practice.

Large levers next to helm are for switching from normal hydraulic to hand hydraulic. In hand hydraulic you spun the wheel to develop hydraulic pressure and this was a very laborious process.

The view looking aft from the front of the Control Room. The motor on the deck in the center is suspected to be the hoist motor for the Control Room and Conning Tower periscopes. The location of the control room scope does not seem to be in a good place. It is at the far aft end of the room behind the ladder to the Conning Tower and cut off from direct view of the helm.

Open grate in the deck leads most likely to the Pump Room and the grating is for drainage of any flooding into the Pump Room, where it can be pumped out through the main drainage system.

The square hatch is suspected to be the access to the Cold Room/Freezer. The padlock seen on the hatch seems to correspond to other food storage areas with padlocks making us think this is that space. Drawings indicate that the Cold Room/Freezer was directly under the middle of the Control Room.

Stern planes on the left, bow planes on the right. Two shallow water depth gauges with the deep water gauge in the center. Horizontal bubble clinometer gauges for angle. Rudder angle indicator is probably for the Diving Officer to keep in the loop.

Another view of the Dolphin Control Room looking forward this time showing some detail in the forward port corner of the room. The enclosed cabinet in the far corner is probably an electrical equipment storage space. Spare parts, fuses, tubes, etc. It's purpose is not known for sure at the present time.

Control looking to Starboard and aft. In many respects this is the general layout for the starboard side of control rooms throughout the coming sequence of submarines through WW II and after. The type of equipment will change with newer and more modern versions as time passes but this was the template for the future.

Electrical panels at the left will become enclosed to prevent short due to condensation and for crew safety as time went on.

Just to the right of these panels is a barometer. This was important to letting the crew know what was happening with weather but also in letting them know the submarine was closed up properly for diving. When all hatches were closed and a small amount of air was bled into the submarine the barometer would register this pressure change and if there were no leaks the pressure would not change. The report "Pressure in the boat", would signal all was well and the dive could proceed. An important piece of equipment indeed.

Moving right we see the row of gauges for the air system and air banks and various pressures. The manifold seen below these gauges is the Trim Manifold which ports internal ballasting water around the boat. Air system valves are to the right and below of this manifold.

These two valve handles are seen in the overhead of the control room in the large scale photo above.

Looking across the Pump Room to the Port side where the York Compressor is visible. The flask seen in the right foreground could hold a verity of gases including Freon used the ice maker. This bottle is seen in the photo showing the compressor for refrigeration. Forward is to the right. The Chill box and freezer are also to the right.

The Dolphin Conning Tower looking forward. On the right is the #1 periscope. Just to the left of that at the top is the bridge access trunk. You can see daylight coming down the hatch.

In the center bottom is the Conning Tower access hatch from the Control Room. Directly above that on the forward bulkhead is the ships helm.

Close up of the Conning Tower helm area. To the left is the port engine order telegraph and the right is the Rudder Indicator showing Dolphin has an 8 degree Right Rudder angle at the time the photo was taken.

The close up provides a look of the top of the mystery object sitting in the Conning Tower. It appears to have a polished brass cover on the top of it. Suggestions as to its purpose welcome.

The Dolphin Conning Tower looking aft. Just to right of center is the #1 periscope used solely in the Conning Tower. The #2 periscope, that was used solely from the Control Room, was housed outside the Conning Tower. This arrangement was eventually done away with and both periscopes could be used in the Conning Tower though the use of #2 in Control remained for a while longer.

As an aside note it has been noted on the barrel of the periscope markings every two feet to allow the Conning Officer looking through the periscope to ask for and get the exact elevation he asks for and also remind him how much of the periscope has been raised.

On the far left is a portion of the hand rail for the bridge access ladder and to the right of that are the Port and Starboard shaft RPM dials. Below them is a desk area with a desk lamp. To the right of these are the pulleys and cables for raising and lowering the #1 periscope. The motor for this can be seen at the foot of the ladder to the Conning Tower in the Control Room.

The right side of the image shows at the top are the Conning Tower Blow, Vent and Drain valves. Next to them are the Torpedo Firing Buttons.

The USS Dolphin was the first submarine to have a Water Tight door in the conning tower to give access to the deck gun. Subsequent sub classes had this feature until wartime modifications removed them. Ladder steps lead up to the cigarette deck.

At the top in this close up are the Conning Tower Blow, Vent and Drain valves.

There to the right of the valves is the Torpedo Firing Panel. The USS Dolphin had four torpedo tubes forward and two aft. These two boxes with buttons on them are firing panels. When the order was given to fire a torpedo a command was given such as ,"Fire One", and the button was pushed. at the same time the command was broadcast to the torpedo room and a firing actuator was pushed for that tube. This was a backup in case there was a malfunction in electronic communication.

The "Butt Kit", a Navy version of the Ash Tray. It was attached almost everywhere and was portable. They were deep to accommodate heavy usage. A peek into the top of this one shows it is almost full to the top and in need of emptying.

The after battery compartment of the USS Dolphin. This space had 30 bunks, 12 of which were two high and wide stacked over the crews mess table and the 18 others were three bunks high on the port and starboard sides. The oval hatch in the deck was the access into the actual after battery compartment and the battery cells themselves.

The Dolphin Crew Berthing and Messing Compartment. The Stainless Steel table is a permanent fixture. Cast steel or aluminum legs hold it to the deck and the 12 benches seem to be the lockers for the 12 bunks over the table.

It was in the lower right foreground where the man photographed sitting at the table in a previous image (number #35) was seated.

The view is looking aft down the starboard side to the water tight door leading to the galley and engine rooms. The ladder and hatch exit just aft of the conning tower fairwater and just under the starboard side of the raised deck, (there are no good photos of this arrangement). Note the bright sunlight coming down the hatch.

Close up of the after Starboard corner of the Crew Compartment of the USS Dolphin. To the left can be seen the ladder to the deck. The black box with gauges at the top appears to be a Hydrogen Monitor. One half of the ships massive battery sits below the deck of this compartment. A build up of Hydrogen gas could cause an explosion. Below that a locked cabinet appears to have four grapefruit sitting on its top.

The bulkhead these objects are attached to is the forward wall of the crews shower room. This space is a little less than twice the size of an enclosed telephone booth, maybe about 4 feet by 4 feet.

Between the grapefruit and Hydrogen detector is a frame for holding any number of notices that could range from a crew list, a watch bill or even a menu of the weeks meals. It could even hold emergency procedures. In this photo it is empty.

The water tight door gives a glimpse into the ships Galley. There seems to a number of holes from removed equipment. This same bulkhead can be seen behind the man seen through the door from the Control Room.

The crews toilet room or "Head" as it is known in nautical terms. There seems to be only one.

A lot going on in this picture. At the top is a lamp, minus the bulb, so men can use the stainless steel mirror to shave. The mirror reflects the underside of the bunk opposite it. The mirror itself hangs on the door for a cabinet that contains, . what? Maybe cleaning supplies.

The sink, counter, back splash appears to be one assembled unit. A wash cloth or rag is stuffed into the niche above the sink. Between the two sinks is a liquid soap dispenser. It appears a towel has been tied below the sink for men to wipe their hands on.

The After Battery well of the Dolphin looking aft showing the arrangement of batteries and the battery cell ventilation system piping as well as at the aft end of the space are the main battery disconnects that isolated the battery from the rest of the electrical bus.

The USS Dolphin Galley on the Port side aft of the Crews Berthing and Mess Room. The door on the right leads forward.

There is a sliding door that closes off the Galley when it is not in use or in port. This is seen hanging to the left with the ventilation louvers cut in it. This was still very much the surface Navy train of thought that the crew could not be trusted.

After WW II the submarine service went to a "open galley" policy and food was available anytime a crewman wanted it. The rule became that you could cook it but you had to clean everything up afterwards. You were treated as a mature adult and you were expected to act as one.

The USS Dolphin Galley close up showing some detail to the left of the galley range with two grill cook tops and two ovens below. There seems to be a grill or cook top at the back. Tucked into a nook at the back of the counter is a meat saw used to portion out the large slabs of meat still on the bone. The saw is for cutting the bone.

There is a drain in the forward port corner to aid in washing and cleaning galley deck which was probably done after each meal preparation so that would be four times a day at sea.

The Store Room, Port side of passageway aft the Galley and across from the Chief Petty Officer's mess table. At left is an unknown space.

Seems to be a lot of Apricots! Maybe the crew liked them. Have to remember that this is 1933 and foods like we have them today were not available. People ate more seasonal foods and more fresh foods. Post WW II was the beginning of major packaged foods sales. The food companies had ramped up to feed troops overseas and if they didn't find a way to keep selling prepared foods they were going to be in trouble.

We've tried to identify the brands. The Apricots are from a brand called S.F.P.. We haven't been able to find anything on this brand yet. There is one can is noted as being "Livingston - Garden Beets", again the brand is still illusive. The up-side-down can is Kadota Figs from the Pratt-Low Preserving Company of Santa Clara, California. Pratt-Low was noted for having a large production of canned Apricots. Since the fig can is up-side-down we are unable to determine if the brand might be the S.F.P. as well. Kadota is a region of California near Merced, California.

At left are the lids to two bulk food bins. What was stored in them is unknown but possibly Sugar, Flour and maybe Beans or Coffee.

The two boxes with "Ward's Fine Cakes" is from a bakery in Ocean City, NJ. that shipped its baked goods, mostly cakes in the early years, all over the north eastern states. Stores would advertise that fact they stocked Wards Cakes in their newspaper advertising. The company is still in business today as Wards Pastry. If it is cakes instead of some other baked goods is not known. Perhaps bread since the boxes are on their sides.

The USS Dolphin Chief Petty Officer's Quarters. At the right is the water tight door from the Crews Berthing and Mess Compartment. Just beyond that is the door to the Galley.

The scullery, where the crews dishes were washed is at the left. The Store Room must be just aft of the galley.

Close up of the Chief table. There appears to be the remnants of some sort of pie left on the table with a fork still in it. After 85 years it is probably stale.

The frame with the bars is actually a Bulletin Board with a glass front and various Navy messages and directives are posted in it. The bars are to prevent someone falling into the glass in rough weather.

Several notable things about this close up. First the door with the strange pattern of screws is notable in several other photos, one looking aft from the control room and another looking aft from the Crews Berthing and Messing Compartment.

The USS Dolphin Generator Room looking forward through the door into the area where the Chiefs dining area was (to the right of the door) and most likely where the food storeroom was at (to the left of the door.)

The USS Dolphin Main Engine Room. The first thing you see on either side of the photo, left and right, are the Diesel Air Start Flasks. High pressure air used to roll the engines over until compression causes fuel to ignite.

Second thing is the ladder from the deck access hatch passes through an opening into the lower engine room. Unfortunately there are no photos of this lower engine room to allow us to know what was in this space.

The next thing that becomes apparent is the forward faces of the two huge MAN diesels. The large wheels are most likely the throttles for increasing and decreasing the engine speeds. The gauges give vital information into the performance of all the cylinders and pressures.

Flanking the ladder, at the front of the engines, are two large clutch handles for engaging and disengaging the shafts from the engines. Note the angles foot plates for the Motor Machinist Mates (later to become Enginemen) to brace a foot against to gain the leverage needed to pull the levers.

The Port engine, looking forward. The shiny bar at an angle, in the foreground, is actually a "T" handled wrench slipped through a handhold.

Pearl Harbor Attack, USS Dolphin (SS-169)

U.S.S. Dolphin (SS169)
Serial 055 Pearl Harbor, T.H.
December 12, 1941.

From: Commanding Officer.
To: The Commander-in-Chief, U.S. Pacific Fleet.

Subject: Detailed Report Offensive Measures Taken and Damage to Enemy During Raid of December 7, 1941.

Reference: (a) CinCPAC conf. desp. 102102 of December 1941.

In compliance with reference (a), the following information is submitted:
On Sunday, December 7, 1941, this ship was moored port side to, Pier #4, in Berth S-8, U.S. Submarine Base, Pearl Harbor, T.H.
At 0755, Japanese aircraft commenced a dive bombing and torpedo attack on Pearl Harbor Naval Base. This ship sounded general quarters, and passed word on the attack. At 0800, machine gun, automatic rifles and rifles were manned and commenced firing on enemy aircraft. In this area the planes were flying very low appeared to have no objective, and were readily identified by large red balls on each wing. During the next hour this ship fired intermittently at enemy planes which flew overhead sporadically. At some time during this period, it was reported to the Duty Officer that an enemy plane had been shot down and dove into the channel somewhere out off Pier #3. The Duty Officer did not witness this. About 0900 fired continuously on enemy plane flying low and heading astern. When plane was about mid-channel and dead astern, the Duty Officer saw smoke start to come from the tail of the plane and it appeared to have crashed beyond the trees in the Navy Yard. It is believed that thi! ! s ship shot this plane down. At 0903, Japanese planes commenced another heavy attack but were flying considerably higher. This ship fired in short bursts when planes appeared to come within range. At 0930, the attacks appeared to have been discontinued, though there was intermittent fire from various places at single planes flying high and not readily identifiable. This ship withheld fire as planes never came within range.
There were no losses nor damage to this ship.
At one time during the attacks, there was a large splash about thirty (30) yards on the starboard bow, just between Piers #3 and #4. It was not determined what caused the splash which was seen by practically all hands.

On a day like today. 1864: At Petersburg, Union General Ulysses S. Grant realizes the town can no longer be taken by assault and settles into a siege.

SS-169 V-7 Dolphin

V-7 was approved in the FY1930 building program. She was a scout cruiser submarine, originally given the designation SF-10, then SC-3. During construction, she was renamed Dolphin in February 1931 and designated SS-169 in July 1931. She commissioned in June 1932.

The penultimate design in the V-boat series was laid down at Portsmouth in June 1930 and emerged as USS Dolphin (formerly V-7, SS-169) two years later. With a length of 319 feet and a displacement only a little more than half that of her three predecessors, Dolphin was clearly an attempt to strike a happy medium between those latter ships and earlier S-class submarines, which were little more than large coastal boats.

The general arrangement of propulsion machinery was identical to that of V-5 and V-6, but even with a surface displacement of only 1,718 tons, Dolphin's scaled-down main engines - 1,750 horsepower each - could only just deliver the surface speed of the larger ships, and her endurance and torpedo load-out were much reduced. Interestingly, however, Dolphin's size and weight were very nearly ideal for the range and duration of the war-patrols that became customary in the Pacific during World War Two, and indeed, the war-time Gato (SS-212), Balao (SS-285), and Tench (SS-417) classes had similar dimensions.

Early in the war, Dolphin herself made three patrols from Pearl Harbor without notable distinction, and her deteriorating material condition soon led to restricting her to training duties - first in Hawaii, and then in New London for the duration of the war. She was decommissioned in October 1945 and sold for scrapping a year later.

ドルフィン (SS-169)

ドルフィン (USS Dolphin, SF-10/SSC-3/SS-169) は、アメリカ海軍の潜水艦。 Vボート (英語版) の一隻で同型艦は無い。艦名はイルカの総称に因んで命名された。その名を持つ艦としては第一次世界大戦時に購入した民間モーターボート「オラベル号(Ora Belle)」を改称した哨戒艇(SP-874)以来6隻目。なお、退役から23年後に深度潜航実験開発潜水艦として7代目ドルフィン (AGSS-555)が就役している。当初の艦名はV-7であり、船体番号はSF-10/SSC-3であった。

建造の経緯 編集

ドルフィンのモデルシップは第一次世界大戦の賠償で得たUボートのうち、Ms型潜水艦の一つである U127型潜水艦である [1] 。1926年に開かれた潜水艦関連の会議において、U127型潜水艦が巡洋潜水艦として最低限の能力を持つとして「潜水部隊の総意」として建造が要望された [1] 。建造に際し、構造一切をアメリカ海軍方式に改めた上で試作艦として建造されたのが V-7 であり、建造途中に命名方式が変わってドルフィンと名付けられた [2] 。

モデルのU127型潜水艦と比較すると、ドルフィンは魚雷の搭載数が21本と艦型の割に多く [3] 、機関も艦型に手ごろなエンジンを得たことにより、艦型自体の小ささと魚雷射線の少なさ以外は、ほぼ潜水部隊の要望どおりの潜水艦となり、おおむね好評であった [4] 。しかし、1930年のロンドン海軍軍縮会議による潜水艦整備計画の修正により、同型艦が建造される事はなかった [4] 。

開戦まで 編集

哨戒 編集

12月24日、ドルフィンは最初の哨戒でマーシャル諸島方面に向かった。この哨戒は、後の空襲に備えた調査も兼ねていた。1942年1月7日にはジャルート環礁を偵察 [6] 。ジャルートとトラック諸島間の航路を哨戒した後 [7] 、1月23日からはマロエラップ環礁を偵察した。2月1日には、空母レキシントン (USS Lexington, CV-2) を基幹とする第11任務部隊(ウィルソン・ブラウン中将)とすれ違った [8] 。2月3日、ドルフィンは42日間の行動を終えて真珠湾に帰投。艦長がロイヤル・L・ルッター(アナポリス1930年組)に代わった。
