I followed the stories about the Russian K-129 (Wiki) for many decades and have had an interest in submarines for much longer. Recently learning about sonobuoys and torpedos has rekindled that interest. This page was made as I started to read Going Deep: John Philip Holland and the invention of the attack submarine (2017) by Lawrence Goldstone as a way to keep track of the patents.Cornelis Drebbel 1572 - 1633 (Wiki) - built a submersible water craft in 1620 and gave King James I (Wiki) a ride on the Thames river. Since it was a leather covered wood structure it's not clear how depth was controlled.

He was involved in early optics including grinding lenses and the camera obscura.
HunleyThe Hunley (Wiki, 1863, Hunley.org) is called the first successful (depending on how they defined that word) submarine because it sank the USS Housatonic (Wiki). A paper dated 23 Aug 2017 from Duke University Confederate Submarine Crew Killed By Their Own Weapon shows that soft tissue damage to the lungs and brains of the crew was the problem. Note that the "torpedo" they used was a "spar torpedo" not an "automobile" type and was on a 16 foot spar. Since it contained about 135 pounds of gun powder. The PLOS article is:
Air blast injuries killed the crew of the submarine H.L. Hunley, 2017-08-23.
Note that the plan was to attach the spar torpedo to the USS Housatonic and then back off maybe 150 feet before exploding it, but something went wrong and the torpedo exploded while still on the spar, much too close to the sub for the occupants to survive. A big part of the design of U.S. military munitions is "Safe and Arm" (MIL-STD-1316) to prevent the type of accident that befell the Hunley. A normal S&A function is to insure that the weapon has traveled a safe distance from the launching platform before it's armed. A common approach is a small propeller that needs to make a predetermined number of turns and/or a minimum amount of time needs to elapse after launch.
From prior reading the crush depth for a W.W.II submarine is about the same as it's length, on the order of a few hundred feet. It took a lot of improvement in metallurgy and sub design to get to the deep diving subs of today.
The W.W.II and earlier submarines were not true submarines like we have today, but rather submersibles meaning they were really surface ships that could submerge and maneuver under water for a very short amount of time. They had very limited range under water because of limited battery capacity.
John Holland (Wiki) is the father of today's submarine, and in the patents section below are key problems he solved. In Reference 1 there are many dozen early designs for underwater vehicles, but they all suffer major problems. Patent 815350 (below) shows some sailors so gives a rough idea of the size of the first Holland Sub. The Electric Boat Co. (Wiki) was formed to build Holland Subs.
At what time was the air compressor for charging the Whitehead torpedoes on board the sub and if it was not then how long between charging the torpedoes until the air leaked out cutting the range in half?
Royal Navy - Holland 1 -
John Holland was cheated out of his patents and removed from the Electric Boat Co. To be replaced by the technician Frank Cable who used electrical heating to dry out electrical cables in a sub that sank.
This is a general idea not limited to torpedoes. Here some examples of way overrated capability. This goes farther than the commercial products where marketing hype is understood by most customers. Here, in my opinion it misleads people in the military about the capability of their equipment. Not a good thing.
While this sight made a number of improvements and did increase accuracy, it was not at all the case that bombing was a precise operation. The internal gyroscope was based on a DC motor with carbon brushes which deposited carbon dust inside the sealed case causing errors. But the main problem was fundamentally that the corrections made were not at all adequate since there were variables that were not at all controlled. This can be seen in the bomb damage assessment (Wiki) reports for W.W.II where not only did the bomb fall in the area of a pickle barrel it missed a factory that was as big as a city block. Even the modern "smart bombs" (Wiki) are not infallible, but are a lot more accurate than W.W.II iron bombs (Wiki).
At the start of W.W.II the torpedoes were either the ones left over from W.W.I or brand new untested designs. It turns out that the new Mk 14 torpedo has numerous problems making it close to totally ineffective. It took about two years to fix all the bugs. So while it was being promoted as the best torpedo ever in fact it was a POS (Urban distionary). Some torpedoes had a claimed range on the order of 25 miles (Wiki: Type 93) but there's no way it had anywhere near the accuracy to hit any seagoing target at that range. They realized the problem and made a modification installing a kamikaze (Wiki) for terminal guidance in the Kaiten (Wiki). Note that most successful torpedo attacks were where the launch point was no more than a few target lengths away.
The Torpedo Data Computer (Wiki) was an mechanical analog computer that solved the problem presented by a moving firing platform and moving target and took into account the speed and course (need not be a straight line) of the torpedo. Only a couple of second order corrections were made so the accuracy decreased rapidly as the target distance grew. I expect that the range of the longest torpedo sinking was far below the maximum claimed range for that model torpedo.

Battle Ships (Wki)The main target of the Pearl Harbor attack (Wiki) was Battle Ship Row where all eight of them were hit along with some other ships and aircraft on the ground. But, the Battle Ship was already obsolete.
Wooden sailing boats had cannons that fired broadside requiring the attacking ship to maneuver parallel to the target ship to allow firing. The W.W.II 16" guns (Wiki) on a battle ship like the Missouri (Wiki) are mounted in turrets so are more flexible. They have a stated range of up to 24 miles. The same problem as firing a torpedo, i.e. moving firing platform, moving target, was solved by the Fire Control Computer (Wiki), and it turns out the the Ford Instrument Co. made both the TDC and FCC. Practical rangekeepers had to assume that targets were moving in a straight-line path at a constant speed, to keep complexity to acceptable limits. So, a defensive strategy was to "chase salvos", i.e make violent turns and head to the splash point of the last shot coming towards you or just steer a tight circle (not a straight line) course.
My supposition is that a 16" gun never sank an target ship at a range of 24 miles, but only at much reduced ranges, maybe 2.4 miles? The reasoning is the same as for the case of the torpedo. That's to say without some form of terminal guidance the probability of hitting the target is very small. It may be possible to fire many shots and use RADAR tracking of each one to reduce the error of the next shot, sort of like firing a machine gun by not using the sights but by looking at where the rounds land. But that's not precision fire control.

Air to Air Missiles (Wiki)
The early air to air missiles were just rockets with no on board guidance. These were not very effective but had an advantage over slower munitions. For example the F-8 Crusader jet (Wiki) was designed to use 20mm cannon (Wiki) because prior Korean war vintage jets using .50 caliber machine guns were able to fire, dive and get in front of the bullets and shoot themselves. The 20mm cannon has a higher velocity round (3,300 fps at the muzzle or 2,250 MPH).
The early patents are all about control and stability underwater. The major concept missing from earlier attempts. Sort of like the key thing the Wright Brothers (Wiki) brought to airplanes was a control system so it could be steered. Prior aeroplanes were focused exclusivity on flying rather than crashing.Wiki), the highest is HY-130.
The below equation is from Yahoo Answers. Note this is about buckling, not ultimate stress so is independent of the grade of steel.
For External pressure design of a long cylinder to resist buckling, the Stress_critical is given by Scr = 0.27*E*(t/r)^3
This is applicable to materials with a Poisson's ratio (Wiki) = 0.3 for steel,
E = the Modulus of Elasticity (Wiki) of the metal, psi (29E6 for steel)
t = the wall thickness, inches
r = inside radius of the cylinder, inches
To this answer you should apply a safety factor of 4.
Scr = .444 * Water depth in Feet [ 64 lbs/cubic foot for sea water divided by 144 Sq in per square foot = 0.444 PSI per foot of depth)
E = 29E6 for steel (i.e. 1,000 pounds of force on a bolt with a 1 sq in cross section will stretch it 0.029")
t/r = TBD
33 Foot inside diameter = 16.5 foot radius = 198" = r (Los Angles Class Sub Wiki)
The above numbers have no safety factor.
The pressure hull thickness is at least 8" thick, probably thicker.
The very first scale model used a clockwork as a power source. The first sub built for the navy was designed to have a combined gasoline engine and a DC motor, but the U.S. Navy changed that to a steam boiler, like used on surface ships, but that turned out to make the inside so hot that no humans could be involved.
The first working Holland sub could use either the engine or motor to power the propeller. This was true for the S-boats where each of the 4 engines could be connected to either a generator or propellers. The later classes of boats were true diesel-electric (Wiki) and the engines never were connected to the propellers.
The S-boats had a range of about 5,000 miles, much shorter than the "Fleet Boats" made for W.W.II that can cross oceans.
Electro-Dynamic Co. (Wiki) made electric motors for electric Launch Co. (Wiki ELCO) which were later used in submarines. W.W. Griscom (Wiki) died in 1897. In 1899 Isaac Rice (Wiki) took over (cheated) John Holland of his patents, took over his company and renamed it Electric Boat Co. (Wiki). He also controlled ELCO and Electric Storage Battery Co. (Wiki) (later called Exide Co. In 1952 Electric Boat Co. became part of General Dynamics (Wiki).

The very early submarines never dived, i.e. they ran "Awash" so that a man's head could be above the surface. But as soon as they could dive they were essentially running blind. The idea was that the periscope could be used to see what was going on but people on ships would have a difficult time seeing the small periscope.
Toward the end of W.W.II the S-band (10 cm) APS-20 RADAR was replaced with the X-band (3 cm) APS- 31 RADAR (9.375 GHz, 200 mile range) which was much better at seeing periscopes.
Currently there are different functions for things called periscopes on submarines:
1. Search periscope, navigation, observation: has both optical and radio antennas, can be rather large
2. Attack periscope: is minimal in size to minimize detection in a combat situation
3. ESM: Electronic Support Measures antennas for a wide range of frequencies (also may be built on submarine
4. Photonics Mast (Wiki): provides the optical periscope function using high resolution TV cameras. Takes up much less space and provides better images and less time above the water line.
The periscope at left uses an special prism to get the image right side up, but suffers in that the distance between (a) and (b) is fixed.
The lenses comprise a right angle telescope.
The periscope at right makes use of collimated light between (c1) and (c2) so the distance between these two lenses can be changed without any effect on the image. This allows the periscope to telescope.

While there were various periscopes (Wiki) long before their use in submarines, one of the first for a sub was by Simon Lake for his "lake submarine".

There are two types of Sonar, one is passive listening and the other is active "pinging" where the time for the echo to return gives the range and the directivity of the transducer array gives the direction.
There are two frequency ranges: normal human hearing (20 - 20,000 Hz) and Ultrasonic (Wiki).
Passive SONAR pays a lot of attention to Acoustic Signatures (Wiki).
There seems to be a disconnect between the 37.5 kHz ultrasonic frequency used by Underwater Locator Beacons (Wiki) on Flight Data Recorders (Wiki) and Cockpit Data Recorders (Wiki). So far as I've been able to determine neither sonobuoys nor SONAR equipment can pick up their signal.

This was an Canadian response to the sinking of the Titanic (Wiki) and amounts to a SONAR system. Note the "Submarine" in Submarine Signal Company has to do with underwater bells, not so much as underwater vehicles. These were used at light houses and buoys according to Submrine Signals (Ref 12).

Plan Position Indicator (PPI)
In the book Pig Boats (Ref 5) they mention that special equipment was fitted to submarines to detect naval mines in the Bay of Japan toward the end of W.W.II. This was developed by the Univ. of California, Division of War Research (Wiki) and was called the QLA. SONAR (Ref 8) pg 263 says: "The QLA echo-ranging equipment is an f-m scanning sonar. It provides a plan-position indication (PPI) of underwater objects within sound range. It can be installed on submarines or surface vessels. In contrast to the searchlight-type sonar, the f-m sonar provides continuous area search coupled with the ability to detect very small objects." The reference has some details of how it works.
In Principles of Underwater Sound (Ref-9) 11.4 Scanning Sonar - FM the QLA principle of operation is covered
In An Ocean in Common (Ref 10) the subs outfitted with the QLA were: Spadefish 20 Oct 1944, Tinosa (SS-283) Nov, Bowfin (SS-287) Dec, Stickleback (SS-415) June. A total of 20 sets were deployed before then end of W.W.II.

Note that submarines typically carry a couple dozen torpedo lengths of weapons (I say that because one torpedo can be replaced by 3 or 4 naval mines) and any of these can be loaded into a tube or removed and something else installed.
The classical submarine weapon is the Torpedo. There are also naval mines that can be launched from the standard 21" torpedo tube.
There is a version of the Harpoon anti-ship missile that can be launched from a torpedo tube called the UGM-84 (Wiki). This came about in the 1970s when Russian surface ships were outfitted with anti-submarine rocket powered weapons so the Harpoon was developed with a range greater than that weapon.
There is a version of the Tomahawk (Wiki) that can be launched from a standard torpedo tube called the UGM-109
6427574 Submarine horizontal launch tactom capsule, Jeffrey C. Callahan, Secretary Of The Navy, Aug 6, 2002, 89/1.81, 89/1.817 - "provides the capability for launching a Tactical Tomahawk cruise missile from a horizontal torpedo tube on a submarine"

Vertical Launch Tubes(Wiki)
Unlike the torpedo tubes that can be loaded with various on board weapons, once the VLT is loaded and the hatch sealed it stays that way. This means they are much more space efficient than torpedo rooms. These standardized launchers are also used on surface ships and can fire many different missiles (Wiki: Mk 41) including the Tomahawk.4934241 Rocket exhaust deflector, Edward T.

During W.W. II HF radio (Wiki) was commonly used for long range and VHF/UHFfor line of sight (Wiki: VHF, UHF, Line of sight). But all of these require the sub to surface.
