There is something unique about diving a submarine - the Bass
The protected waters of Connecticut and Rhode Island were the site of much of the US Navy's early submarine development efforts, and continue to be even to this day. Many of the Navy's early submarine designs were less than successful, and a number of these boats, some of which were obsolete before they were completed, were used as subjects in weapons tests. If you would like to see a sub closer to home, you may tour the USS Ling in Hackensack.
There are also several German U-boats in the region, most notably the U-853.

The Bass was an unsuccessful design. Her three-ship class was envisioned as long-range, long-endurance attack craft, designed to patrol in distant waters, and sported a number of very advanced features for their day. However, many of these features did not work as well as hoped, and the boats were plagued with mechanical difficulties, unreliable propulsion systems, and poor handling characteristics, both at the surface and submerged.
The Bass and her two sisters were huge - 340 ft, 2000 tons - over twice the size of most contemporary boats. For some idea of her size, the Bass dwarfs the nearby
U-853 of almost twenty years later - 251 ft, 1051 tons. In fact, the U-853 would probably fit inside the Bass. The Gato class submarines that were the WWII workhorses of the US Navy in the Pacific were actually smaller than the Bass, at 311 ft, 1816 tons. Even the modern Los Angeles class nuclear attack submarines, largest of their type, are only some 20 ft longer, although considerably heavier.
Bass (right) and a sistership. Evidently, the forward diving planes retract into
the hull, which explains their absence on the wreck.
Because of her shortcomings, the Bass was forced into early retirement less than 15 years old, but called out again for wartime service in 1940. Her duties were mostly patrol and training, and she never saw combat. After a devastating internal fire, she was converted to cargo duties, and was eventually used as a test target, a fate similar to several previous submarines.
The first Bass (SF-5) was launched as V-2, 27 December 1924 by Portsmouth Navy Yard, sponsored by Mrs. Douglas E. Dismukes, wife of Captain Dismukes, and commissioned 26 September 1925, Lieutenant Commander G. A. Rood in command.
V-2 was assigned to Submarine Division 20 and cruised along the Atlantic coast and in the Caribbean through November 1927 when the Division sailed for San Diego arriving 3 December 1927. V-2 operated with the fleet on the west coast, in the Hawaiian Islands, and in the Caribbean until December 1932. V-2 was renamed Bass 9 March 1931 and in April was assigned to Division 12. On 1 July 1931 her designation was changed from SF-5 to SS-164. On 2 January 1933 she was assigned to Rotating Reserve Submarine Division 15, San Diego. Bass rejoined the fleet again in July 1933 and cruised along the west coast, in the Canal Zone, and in the Hawaiian Islands until January 1937. She then departed the west coast and arrived at Philadelphia 18 February 1937 where she went out of commission in reserve 9 June.
Bass was recommissioned at Portsmouth, N. H., 5 September 1940 and assigned to Submarine Division 9 Atlantic Fleet. Between February and November 1941 she operated along the New England coast and made two trips to St. Georges, Bermuda. She arrived at Coco Solo, C.Z., 24 November and was on duty there when hostilities broke out with Japan.
During 1942 Bass was attached to Submarine Division 31, Squadron 3, Atlantic Fleet. Between March and August, while based at Coco Solo, she made four war patrols in the Pacific, off Balboa. On 17 August 1942, while at sea, a fire broke out in the after battery room and quickly spread to the after torpedo room and starboard main motor, resulting in the death of 25 enlisted men by asphyxiation. The following day Antaeus (AS-21) arrived to assist the submarine and escorted her into the Gulf of Dulce, Costa Rica. Both vessels then proceeded to Balboa.
Bass remained In the Canal Zone until October 1942 when she departed for Philadelphia, arriving on the 19th. After undergoing repairs at Philadelphia Navy Yard Bass proceeded to New London, Conn., where she conducted secret experiments off Block Island in December 1943. She was again in Philadelphia Yard for repairs from January to March 1944. During the remainder of the year she was attached to Submarine Squadron 1, Atlantic Fleet, and operated out of New London in the area between Long Island and Block Island. Bass was decommissioned at the Submarine Base New London 3 March 1945 and "destroyed" 12 March 1945.

Today the Bass lies in two pieces. The forward third of the hull broke off during sinking, and lies about 50 ft south of the main wreckage, skewed off at an angle and listing 45 degrees to port. There is usually a rope between the two pieces. The break occurred just forward of an internal bulkhead, so the bow section is wide open for penetration. The forward diving planes are not evident, but the torpedo doors are large and obvious. The anchor bit in the bow is of an odd shape that gave the boat a distinctive forward profile, and is worth a look.
The upright aft section, with the conning tower intact, is more interesting. Penetration of the hull at the break is possible through the hatches in the bulkhead. Penetration of the conning tower is also possible. Most of the decking has rusted away, revealing a maze of pipes below, and the cylindrical pressure hull beneath. Swimming back to the stern, you will find the most interesting area of the wreck. The dual propellers lie half buried in the sand, with the aft diving planes just behind, set permanently at a hard down angle. Above these are the large frames that guarded against entanglement, and behind and mostly buried is the rudder.
Large schools of Ling swarm over the bottom around the wreck. Higher up, cunners are dominant. Owing to the depth, this is usually a dark dive, with little ambient light.

Following builder's trials, outfitting, and crew training, USS S-5 (SS-110) departed Boston Navy Yard on 30 August 1920 to undergo full-power trials off the Delaware Capes. On 1 September, as S-5 dove in the afternoon sun, something went terribly wrong. The boat took a sharp down angle and water poured into the boat. The Main Induction valve was supposed to be closed after the engines had stopped rolling and before the valve head just aft of the Conning Tower went under water. This timing was so important that it was normally the Chief of the Watch's job to do it. An experienced person had to be able to make the judgment. Too early and the engines sucked the air pressure down in the boat and conserving air was of primary importance in the days before CO2 scrubbers and O2 generators. Too late and water was sucked down the induction into the boat. It had to be early enough to insure the boat could blow up quickly if the induction valve didn't shut all the way or leaked badly.
It was a delicate balance. The COB of S-5, GMC Percy Fox, was the man of the hour. He, however, got distracted and was late in shutting the valve. When water started to stream into the boat, he lunged at the lever and ---- jammed it open!. The only way to stop the water was to shut the four individual ventilation line valves in each of the compartments other than the Engine Room (that room's valve was shut on shutting down the engines). The crew raced to shut the valves and got all of them shut in good order ---- except the Torpedo Room. That valve would not move. The men in the space abandoned the room shutting the door and dogging it. The Torpedo Room quickly flooded. The boat had taken on about eighty tons of water through all the ventilation line openings and had a flooded Torpedo Room. She settled to the bottom in 170 feet of water.
Things looked bad. The boat was tight, true enough, but the crew had no way to get out and could not wait until help arrived, there was not enough air. There was no marker buoy, no escape trunk, no escape lungs - it was not good. The Captain, LCdr Cooke, had a plan however. He knew the boat was two hundred thirty-one feet long and the water was only one hundred seventy feet deep. If he could pump enough water out of the boat to lift the stern, the boat would pivot on the flooded bow. When it rotated upward enough, the water now in the bilges holding the boat on the bottom could pour through the watertight doors from the Motor Room, to the Engine Room, then to Control then to the Battery Compartment. This would lighten the stern more, and with just a bit of luck, maybe they could get the stern to stick out so the Motor Room hatch would clear the surface. It would be tough. The hatch center was 178 feet from the bow so, if the boat were standing straight up (90d down bubble), the hatch would be out of the water, if the bow didn't dig in, if the boat could stand up, if the waves weren't too high, if the depth gage was accurate, if-, if-, if-. It was worth a try - actually, it was their only hope.
Timing had to be correct on this one too. The water that would spill forward would go as far as the Torpedo Room bulkhead then start piling as the boat started up. It would soon enter the battery well (it wasn't watertight) and would immediately start producing chlorine gas. The doors had to stay open long enough to let the water spill through but had to be shut to prevent the gas from contaminating the air, which could not be renewed. If the Battery Compartment door to Control wasn't shut soon enough the chlorine would suffocate the crew, if it were shut too soon, all the water possible would not have drained through and the boat would not tilt up far enough. There was only one chance, they took it.
The aft ballast tanks were blown. The boat remained locked in the grip of the ocean floor mud. The aft normal fuel oil tanks were blown overboard. Slowly, the boat's stern lifted. The water in each compartment slid toward the forward bulkhead of that compartment. Then as the stern lifted more, the water overflowed the bottoms of the doors and cascaded into the next compartment forward. Then everything happened at once. As the boat tilted up, more water poured through each door, loose gear, deck plates and everything crashed to the forward end of the compartments and sometimes through the doors with the water. Several crewmembers were washed from their feet or torn away from handholds by the water and the flotsam it carried. A couple went through doors to fall the length of the next compartment as the angle got steeper and steeper. The water in the Battery Compartment got deeper as more water fell from above. Soon those in the space were swimming for their lives to keep their heads above the rising water level.
Now the crew had to climb up an almost vertical submarine hull to go aft. Those in the Battery Compartment had to climb up a rope made of curtains to the aft end of the compartment. The crew evacuated aft to Control Room. There was now a problem. The Engine Room/ Control Room watertight door had slammed shut during the evolution and now had several feet of water on it. In addition, for the men in Control, it was, because of the angle on the boat, now in the overhead and had to be pushed up to open. With a full load of adrenaline flowing, and with the men in the Engine Room lifting and the men below pushing, the door was opened. More water slammed down from the Engine Room but, when the waterfall stopped, the Control Room could be evacuated. All the men there climbed into the Engine Room. The door was reshut and dogged.
The manhole cover into the Tiller Room was unfastened and removed. Captain Cooke climbed through along with other crew members. They were mighty pleased to hear the sound of waves against the hull, but it was not enough. Listening and tapping, they found the water level to be about 17 feet from the stern post. It was not nearly the 52 feet and change necessary to uncover the Motor Room hatch. Now all that stood between them and the open ocean air and escape was three-quarters of an inch of good Bethlehem Steel. A hand drill was found and a quarter inch hole started. When the hole was finally pushed through, the crew was relieved that a stream of water did not enter.
One of the crew found the 3/8" electric drill in the Engine Room and they went to work on the hull with vigor. Now this drill was not one of the nice plastic-housed double-insulated drills of today. It was metal-cased, not too well insulated, being handled by a wet sailor in wet cloths with his back against a well-grounded hull. The ship's electrical circuits, having long since grounded out, made the job dangerous at best. When the drill was started, some of the current drove the drill, some drove the man. It was agony. But it was their only hope. Over the course of the next several hours, four holes each about a half inch in diameter was drilled through the hull. Then the power failed, the lights went out, the drill stopped and there were just the four little holes.
A hacksaw blade was passed through one of the holes and the men started sawing away. By early the next morning, they had cut a hole one half inch high by four inches long through the hull. The boat had been down for nearly eighteen hours, the air was getting bad, it was hot, damp and the slight amount of chlorine in the air made life just that much worse. The hand drill was pressed into service again and more holes were cut. Captain Cooke looked through the hole and watched as a ship, not more than five miles off, passed by. By the time the boat had been down for 24 hours, the hole had been enlarged to a triangle measuring four inches by six inches. By this time the drill was played out and the crew nearly so.
The captain fastened an undershirt to a 10-foot length of pipe and stuck it through the hole and started to wave it. He hoped to attract some attention, even though that was a vain hope in the vastness of the sea. Now, luck struck. The steamer SS Alanthus almost didn't, then did, stop. She put a boat over to investigate this mystery. The captain of the Alanthus was a true seaman and when faced with this thing sticking up and a flag waving, conducted himself and the conversation in a true seaman's manner:
"What ship?" he asked with his face near the hole.
"USS S-5, " came the reply.
"What nationality?" he asked.
"American, " came the reply.
"Where bound?" he asked.
"TO HELL BY COMPASS!!!!!" came the reply.
The Alanthus could not help in cutting the crew out but rigged a pump to get some air in and poured cool fresh water into the opening to help cool the crew. She also rigged cables around the stern so it wouldn't slip beneath the surface before help arrived. At about 1800, she attracted a passing Pan-American liner the George W. Goethals. This ship had a radio and called for help. The Navy immediately dispatched two destroyers and the battleship Ohio to the scene. The chief engineer aboard the Goethals decided not to wait for help but to get to work making the hole big enough to get the men out. By 0145, it was big enough to squirm through and the crew started to exit the ship. All thirty-seven crewmen and three of the officers passed out through the hole. By 0300, Captain Cooke had shut and dogged the Motor Room door and left his command.
The Ohio came on the scene shortly afterward and commenced securing heavy towing cables around the protruding stern. As they started a slow tow toward shallow water, the boat bobbed a couple of times, parted the cable and sank. A salvage attempt was made through November then again the following year. The next summer, the Navy called off the effort and struck S-5 from the Navy List in 1921.

From: Commander C. W. Fischer, G. C., U. S. N.
To: Commandant, Fourth Naval District.
Subject: Salvage of S-5; report of conditions when work was abandoned on August 30, 1921
(a) My letter to Commandant 4th Naval District, August 19, 1921
1. My letter, reference (a), dated August 19, 1921, reported the status of salvage work on the S-5 on that date. Since then, owing to bad weather, only three days diving has been done, on August 20, 24 and 30. The conditions discovered as the result of the diving on August 24th were such that a radio dispatch was sent to the Commandant, Fourth Naval District, on August 25th, in part as follows:-
"... taking into consideration the still unknown location of certain air leaks, the difficulty of stopping those already located, the bad weather, and fatigue of the personnel, I am extremely doubtful if she (S-5) can be raised before the beginning of the bad season. Instructions are requested as to continuing the work."
2. On August 30, 1921, in accordance with instructions from the Navy Department, Operations, the Commandant of the Fourth Naval District directed that work on the S-5 be abandoned and that FALCON return with all equipment to the Navy Yard, Philadelphia. Diving was stopped on August 30th and the FALCON proceeded to pick up the mooring buoys, anchors and chain.
3. The condition of the S-5 when she sank is given in paragraphs 2, 3 and 4 of my report, reference (a). The plan for salvage and the methods for carrying this plan into effect are also described in paragraphs 5 and 6 of reference (a).
Present Condition of S-5.
4. When diving was stopped on August 30th, 1921, the condition of the S-5 was as follows:
(a) Vessel lying on a hard, flat, sandy bottom, listed about 20 to port, and down by the head about 6 feet. Position about 40 miles E. S. E. of Cape May, Lat. 38 - 41' N, Long. 74 - 08'W. Depth of water 144 foot at low tide.
(b) the port bow diving rudder is broken short off. The starboard one is rigged out, and set at hard rise.
(c) Torpedo Hatch: the door or flap in the superstructure over the hatch has been opened and the wedge-like shape in front of the torpedo hatch has been filled in with concrete to prevent the hatch springing open when pressure is applied to the interior of the vessel. This hatch has been tested with air pressure and no leaks were reported.
(d) Torpedo Compartment: A hole has been pierced through the hull about 8"x6" in size, near the forward end of the compartment, between frames 18 and 20, on the starboard side. The bottom of this hole is just above the level of the deck in the torpedo compartment. A T-N-T bomb was used to cut this hole. The air inlet valve at the top of the compartment, leaking into the superstructure ventilation pipe from the main induction valve was left open, according to the Commanding Officer. It was through this valve that water entered the torpedo compartment and caused the S-5 to go down by the head as she sank. The Commanding Officer also reported that the valve to the compartment air salvage line was open. The after bulkhead of the torpedo compartment is probably ruptured at or near the top of the boat, as shown by the fact that when air is forced into the torpedo compartment through the hole in the bottom, large quantities of bubbles are immediately seen to issue from the battery compartment hatch.
(e) Battery Hatch: the original hatch was removed by using TNT. and the hatch coaming itself removed and is now on the FALCON, thus leaving the hatch trunk and the battery compartment open to the sea. The size of the battery compartment made it necessary to remove as much water as possible from it. It was by no means certain that the opening in the bulkhead between the battery compartment and the torpedo compartment was low enough to permit the battery compartment to be drained by way of the torpedo compartment. In fact it is more than probable that the opening is near the top, the door sprung or the deadlight in the door broken. Owing to the double hull and the presence of the battery it would have been difficult to pierce a hole through the hull from the outside. It was therefore decided to remove the hatch cover and fit in place of it a false cover with a device in the false cover for removing the water. After one type of false cover had proven unsatisfactory, we installed a one inch plate fitting on the top of the hatch coaming and held down against a 3/4 " rubber gasket by 16 hook bolts. The cover has a 4" pipe into it, connected to a length of 3" flexible suction hose which extends down to the battery deck and their terminates in a double strainer. The upper end of the 4" pipe extends through the hatch cover and about three feet above the superstructure deck where it is fitted with a non-return flap valve which will permit water to pass out of the compartment but will prevent its entry. The air for blowing is admitted through a two inch pipe screwed through the hatch cover and fitted at its upper end with valves and connections for four one inch air lines.
Then this device was tested, air was found to leak around the coaming itself as well as from under the false cover. The bolts securing the coaming were removed and the whole coaming, false cover and fittings brought on board the FALCON, where it was found that the coaming itself was cracked and that five of the hook bolts were not holding. The crack has been repaired (with smooth-on instead of brazing as previously reported), and the device is now ready to be replaced.
On August 24th, it was found possible to send a diver down in the torpedo hatch trunk, and examination of this trunk disclosed two vertical cracks, one on the port side and one aft, running nearly all the way from top to bottom of the trunk and averaging about 3/8" wide. The vertical seam in the trunk (on the starboard quarter) appeared to have the caulking started. These cracks permitted air to escape from the interior of the vessel into the upper ballast tank from which it escaped and made its appearance along the starboard side (the high side) of the superstructure, abreast the conning tower. The divers reported it will be possible to close part, if not all, of these cracks , by driving pine wedges into them.
(f) Battery compartment: This compartment, as previously described, is open to the sea because the hatch is off. It also is in communication with the torpedo compartment through probable rupture of the of the forward bulkhead. It is in communication with the upper ballast tanks through the cracks in the battery hatch trunk. There being no other available way to remove water from the central compartment, several TNT bombs were placed against the bottom of the door leading to the central operating compartment and exploded. It is believed that this door has been damaged sufficiently to permit water to drain from the central compartment into the battery compartment.
The divers reported a mass of material jammed up under the bottom of the battery hatch trunk blocking one half of its area. A piece of 16 gauge metal about two feet wide extends up inside the trunk to within a few inches of the top. From these facts, and the further fact that the forward bulkhead of the battery compartment permits free passage of large volumes of air through it, I am of the opinion that the battery explosion reported by the Commanding Officer must have been of considerable force. The failure of the forward bulkhead may have been due to the increased pressure on it when the S-5 was towed over the rumored "deep spot" of 200 or more feet. The cracks in the hatch trunk may have been caused by the TNT bombs used in removing the hatch cover and blowing the central compartment door, but from the description of them and of the maps of wreckage under the hatch, I incline to the opinion that the battery explosion lifted the whole battery deck and is the cause of most, if not all, of the other damage.
(g) Conning Tower and Central Operating Compartment: the conning tower hatch was cut off at the hinges with TNT and a 1" steel plate on a 3/4 " rubber gasket secured to the coaming with 16 hook bolts. During the operations the binnacle stand, close to the conning tower was sprung and was found to leak air around the base. It was, therefore, removed and a steel patch fitted over the opening, using the original bolt holes or studs, supplemented by hook bolts. Some minor leaks still exist in these patches. The eye-port glasses in the conning tower, some of which were found to be cracked or broken, have been replaced by steel and oak disks, held in place against rubber gaskets by the usual eye-port keeper rings. As stated in a previous paragraph, it is believed that the door between the central compartment and the battery room has been damaged sufficiently to permit the draining of the bulk of the water from the central compartment to the battery compartment.
(h) Engine Room: the engine room hatch has been fitted with a 3" channel iron strongback held down by two stout hook bolts. To provide a place to hook one of these bolts it was necessary to cut away a piece of the superstructure deck. To provide egress for the water, TNT was used to cut a hole in the outer hull, between frames 96 and 98, near the forward end of the engine room, and about four feet to the starboard of the duct keel. This hole, irregular in shape, is about 18" x 22", and communicates with the engine room itself, through a lubricating oil tank which had been used as an emergency provision locker. The manhole cover for this tank had been taken off to get at the provisions, and was left off by the crew. Thus through this hole in the bottom access is gained to both the engine room and the motor room, because the door to the motor room, had been left open by the crew. This is known because when air was forced into the engine room it escaped from both the engine room and motor room hatches. The engine room hatch is now practically air tight, but the engine room is full of water. Now that the engine room hatch is tight, air still escapes from the engine room, appearing in bubbles from the periscope sheers above the main induction valve, from the high side of the superstructure abreast the conning tower, and from the superstructure ventilation pipe between the engine room and the main induction valve. This latter fact was determined by removing bolts from a flange in the pipe (10" in diameter and apparently of galvanized steel) and wedging the flanges apart. A hand hold plate in the upper ballast tank was removed from the starboard side abreast the after end of the periscope sheers, but no air escaped; hence it is believed there is no communication between the engine room and the upper ballast tanks. The other air leaks seam to indicate that air escapes from around or under the cover placed over the main induction valve. If this is so, (and the leaks from the ventilation pipe support this view), the 10" air intake valve in the engine room is not tight, (this valve seats with pressure from the outside).
Leaks may exist through the forward engine room bulkhead and through the battery ventilation duct into the battery compartment, but this has not been definitely established.
(i) Motor Room: the motor room hatch has been re-enforced by a 3" channel iron-strongback as was used in the case of the engine room hatch. In order to secure the two hook bolts the screws were removed from the portable superstructure plate around the motor room hatch and the plate lifted off. The motor room hatch is practically airtight. The motor room is in communication with the engine room because the door between is open.
(j) Tiller Room: the forward door of the tiller room is closed but the compartment is open to the sea through the hole cut in the hull which enabled the crew to escape.
(k) Main Induction Valve: This valve, difficult of access, because of its position in the periscope sheers, was closed by concrete. A section of the plating of the shears was cut out by TNT, and concrete poured down on top of the valve. Indications are that this work dose not hold air, because of the air coming out of the top of the periscope sheers, and that from the starboard side of the superstructure. Since writing reference (a), two more plates have been pulled off of the side of the periscope sheers, which operation has reveled a large volume of escaping air that may well be ascribed to leaks through or around the main induction valve. I have, therefore, changed the opinion expressed in reference (a) that the induction valve was tight, and now believe that it leaks. This fact can be determined by breaking the ventilation piping forward and aft of the main induction valve and blank flanging it. Then, if air is turned on the torpedo compartment and the engine room , non escapes through the periscope sheers, there will be reasonable proof that the induction valve is not air tight. This is, however, a difficult and tedious job, and has been only fairly started when orders were received to stop work on the S-5.
(l) Superstructure: the superstructure deck has been turn up or removed in the following places: around the battery hatch; between the conning-tower fair-weather and engine room hatch on port side, to expose the 10" ventilation pipe; around the engine room hatch; around the battery hatch
(m) Bridge: the space around the conning tower hatch was so restricted and cornered with radio antennae, bridge instruments, ect., that the divers could not work. The port half of the bridge rail (chariot), complete with teak backing, weather plating, ect., was, therefore, pulled off and brought to the surface. several plates have been torn off the periscope sheers.
WORK REMAINING TO BE DONE.
5. Before any further determination of facts regarding the condition of the S-5 can be made, or the vessel raised by compressed air, the following work must be done:
(a) Stop leaks due to cracks in the battery hatch trunk.
This is difficult and painstaking work, but I believe it is can be accomplished by using pine wedges. Estimated time 12 diving days.
(b) Replace the battery hatch closing device with its piping for the admission of air and the egress of water. Estimated time - 3 diving days.
(c) Tear off, cut off, or otherwise clear away the superstructure decking forward and aft of the conning tower fair-weather, so that the ventilation pipe (about 6" dia. forward and 10" dia. aft) can be broken and blank flanged. None of the flanges located thus far have all their bolts accessible and it may be necessary to cut the pipe by hack-saw or chisel. This is the most difficult job to do. Estimated time - 15 diving days.
6. After this work has been done, it is believed that the hull will be found to hold air. If such is the case, the next step is to:
(d) Drill holes in each of the six main ballast tanks so that water can be blown out of them uniformly. No definite results have been as yet obtained by attempting to spring the main ballast kingpins, although it is believed that at least one of them has lifted.
7. The S-5 should then be ready for blowing and lifting, unless other leaks or breaks show up, -in which case they must be stopped or reduced until the total leakage is much less then the available air compressor capacity when operating at about 85 lbs. per square inch, (the static pressure on the bottom is 64 lbs. The excess of 21 lbs. is the allowance for losses in transmission through the hose, losses due to reduction in temperature, and an allowance of, say, 8 lbs. excess pressure to cause the water to flow out of the vessel).
8. Owing to the uncertainty as to the integrity of bulkheads, it is not certain that the S-5 can be balanced while she is lifting. If the engine room bulkhead is tight, as there is every reason to believe, there should be no difficulty in raising the stern first and then lifting the bow. If this bulkhead is not tight, however, it might be necessary to resort to a pilot pontoon or some similar service to bring her to an even keel fore and aft.
9. It has by no means been demonstrated yet to my satisfaction that it is impossible to raise the S-5 with the methods that have been followed during 1920 and 1921. In the last analysis success will depend on the ability to stop the existing air leaks. Several of these are known to involve difficult and tedious, but not impossible, work. In my opinion it will be possible to raise her unless it is found that the inner hull is leaking under the upper ballast tank, in which case I do not believe the leak can be stopped. On the other hand, the value of the vessel after being raised is doubtful due to her long submergence with consequent corrosion and deterioration. Under the existing conditions, I do not believe any further expenditures in the effort to raise her would be warranted. It is suggested, however, that next summer, if training in deep sea diving is needed, that such training might be given on the S-5, as the work to be done will involve almost every operation required of divers at such great depths.
CAUSES OF FAILURE.
10. In my opinion the reasons for the lack of success in raising the S-5 are as follows:
(a) Failure of the cement or concrete to seal the main induction valve.
(b) Damage to battery hatch trunk and possible damage to interior ventilation and other pipes, due to a battery explosion.
11. Four hundred and seventy-seven dives have been made on the S-5, without any serious casualty or sickness. In only about 10% of the dives were any evidences of caisson disease noted, and these promptly yielded to treatment in the recompression chamber. Only two cases of caisson disease were deemed of sufficient importance to be reported to the Bureau of Medicine and Surgery. This record is believed to be rather remarkable, especially when it is considered that practically none of the divers had worked in water as deep as 100-feet for two or more years before the S-5 work was begun.
12. It is a matter of keen regret to me that the S-5 has not been successfully salvaged. I wish, however, to state that failure has been due to no lack of effort or enthusiasm on the part of the personnel. Both officers and men have worked faithfully and well in the performance of this duty, which has been arduous for all, and hazardous for the divers. As a result of these efforts, the Navy now has a vessel equipped for deep sea diving, and a force of some fourteen divers capable of steady, efficient work in depths up to 150 feet.

The Blenny after post-war GUPPY conversion.
The Blenny doesn't really belong here, since she is actually sunk off Ocean City Maryland, several hours drive south ( occasionally wrongly reported as Ocean City NJ. ) She lies on her starboard side, completely intact, with several large holes cut in her deck. Unlike some old submarine wrecks, which honestly resemble sewer pipes more than ships, the Blenny retains her shape and character, and makes an interesting dive if you are ever down that way.
