    I earned my dolphins in 1970 on USS Hardhead SS-365, a WWII submarine similar to the one in the video. Hardhead was in the improved, deeper diving Balao class and was retrofitted/upgraded in the 50’s and again in the 60’s from the one in the video. We didn’t have a deck gun and our bow was more rounded like modern “nuke boats”. We had a tall “North Atlantic sail” over the conning tower and mast area. The sail was made of a steel frame with a fiberglass covering and was free flooding. The tall sail was to protect the guys on watch when on the surface in the stormy North Atlantic. There were many changes inside the boat as well including electronics that I worked on. All of these changes made it an HK (hunter killer) “Guppy IIA” submarine. Guppy stands for “greater underwater propulsion”. One key point in the video… We flooded tanks when diving to subtract buoyancy, not to add weight. We’d “drive” down with bow and stern planes then level off by pumping water back out.
    We trained often, stalking anything that came across our path.
    We believed …. Convinced, we were bad-ass hunters.

This video didn't show anything I hadn't known about and trained for but it was a fun and very rewarding viewing. I went on to qualify aboard 3 nukes during the balance of my career. Included was a TDY, 72-day sea buoy-to-sea buoy trip aboard the USS Shark where we experienced a crazy Ivan. It happened so fast that the only person to even know what happened was an ET manning the sonar PPI.

    For a short video, this was an outstanding intro to the WWII American Gato and Balao class U-boats. Two machines the German type 7 and type 9 U-boats did not have that the US did was, 1st, a fresh water condenser that made fresh water out of sea water allowing the crew to actually take a shower once in a while, and 2nd , air conditioning. Neither were luxuries in the Pacific. A 1940's U-boat could not carry enough fuel and fresh water to keep the crew alive in the tropical heat. Given the vast distances they sailed it was a required device. Even with a fresh water maker they had to take a "navy-shower". The AC was installed mostly to keep the air in the boat dry so that electrical failures, and fires, were reduced. Even with AC a WWII U-boat was an uncomfortable ship. Which is why I was a surface navy officer. I'll admit it- Subs scared the hell out of me.

      In World War II it was the scariest fighting condition imaginable because days into the war we realized that the fancy new torpedoes that had been developed for our subs, destroyers, and torpedo bombers (The Mk. XIV) Was defective, the submarine fleet deployed to fight a war with a weapon that would not maintain depth properly, would not detonate when fired under an enemy ship (Magnetic detonators of the day were very unreliable), would rarely detonate when fired in contact detonation mode, and would occasionally wheel around and bounce off the hull of the boat that fired it (And this problem persisted past the redesigned detonators and has been attributed as a likely cause for some boats never returning). Any sailor that maintained their sanity fighting in those conditions is one tough SoB.

      My sister and I would go to the escape tower and make the ascent in any group of sailors who had not made the ascent during the regular training days. They HAD to do it if a couple of kids could!
      I also remember playing with the torpedoes that were running to test their electronics. They would move their rudders as we walked close to them, pointing at us.
      As kids, we moved a lot - from Gitmo to Key west, to New London to Norfolk to Boston to Scotland to Egypt. Sometimes we'd move every other month.

      @@davehageman7513 Apparently, there were windows into the tanks that pumped fuel into the engines when it was running. Since the sea water was denser than the fuel, it would settle at the bottom of the tanks given enough time. When the diesel engines were running, the engineers would monitor the fuel levels through these windows, and keep a look out for the visual separation between the fuel and the water. If the water was getting too high (close to being pumped into the engine), they would switch the fuel intake to come from the other tanks, staggering the usage of fuel tanks so that while one was being used, the other could have time to “settle” with the sea water and allow the liquids to separate.
      In short, there wasn’t a major issue with sea water in the fuel, due to the density differences between the liquids. When one tank came close to being of issue, they’d switch to another one to give that tank time to become safe to use again.
      For reference I just googled “diesel fuel mixed with seawater submarine issue”, and I’m paraphrasing a forum post I found on a submarine enthusiast site (who knew those existed!)

I can't find it now, but according to the shore battery that sunk the boat, they hit the sub (it was running on the surface) with the first shot, which was in the conning tower.

    I served and qualified on a Balao class boat, and we had 16-cynder Gimmies in a V16 configuration. The aux engine in the after engineroom was replaced with the HP air compressors. Some pieces of equipment were placed in different locations on a Balao class boat. We never used the term "closed" for a hull opening or hatch, as it could be confused with the word "clothes", we only used to refer to a hatch or valve as being "open" or "shut." I was on the USS Blenny, which had been reconfigured to a Guppy-II class bow configuration for greater underwater speed, although it didn't add that much speed. As fresh water was at a premium, no washing machine, and we didn't have icecream lockers in afterbattery birthing area, it was in the freezer below the crews mess and galley. We had a sonar room down there too, for our special Puff Mounted sonar which had been installed on four Balao class boat, Blenny being one of them. We had no reduction gears between the main motors and props. The main motors, two of each of the four main motors were connected fore-to-aft on the same prop shaft, with direct speed control of each shaft and it's motors controlled by the controllermen at "the sticks" in Maneuvering room. The fwd head had a sanitary tank of it's own, as did the two side-by-side heads in afterbattery, but the aft torpedo room head had no sanitary tanks, and I think it only used while on the surface. Not a bad presentation, took a nice trip down memory lane, thanks. Benny

    Torpedo room hatch does not lead to the bridge; it leads topside. It's an escape trunk. There's also a torpedo loading chute in the TR and after TR. The screws counter-rotated. The 40mm guns were forward and aft of the SAIL, not the conning tower. After planing to the surface, the diesels were started and their exhausts could be routed to the main ballast tanks to expel the seawater inside them, thereby conserving air in the blow banks. It took hours to recharge blow banks with high pressure compressors, so this was a good strategy called "surface without air". It also created an oily diesel residue inside the ballast tanks, which slowed corrosion. Air for the diesels first ran through the rest of the boat to ventilate and cool it before making its way to the engine rooms. These boats were quite hot and humid and fresh air coming through the vents and doors throughout was very much welcomed when the diesels started up. The diesels could also be deployed to remove smoke from a specific compartment in the event of a fire after it was extinguished.

      They're so complicated, and thus expensive, the US never bothered to test its Mk 14 torpedo before the war because it cost too much. This was a bad idea as they either didn't work, or were more dangerous to the user than the target. This cost the US dearly early war, as they would have crippled Japanese shipping and brought the war to an end years earlier if they had a working torpedo (instead impacts were duds). Among other issues 1: It turns out things the primary detonation sensors were looking for actually vary quite a bit by when and where in the ocean you are 2: The firing pin for the backup detonator wasn't parallel to the front, so the shock of impact would bend it rather than slam it into to the primer to set off the explosives

    As a former silent service sailor (Ohio Class) I'm amazed at how well designed and advanced (for the period) these boats were. Marvels of engineering in their day. Some things I didn't see were how they'd load torpedoes into the boat and their fresh water maker. Also not mentioned is whether or not they had a snorkel valve. Ours had a water sensor and it would slam shut if it got wet, if we were running a diesel it would pull air from the boat momentarily and make your ears pop and we'd use it to equalize air pressure like what was mentioned in this video. Also only 10 secs to rig for dive? Holy crap. That was well before subsafe, though and it was a different time. Fascinating presentation

      Forward and Aft Torpedo would have loaded torpedoes through a hatch topside, and the torpedo would be slid down a removable rail system by crane, not too dissimilar to how it’s done on boats today.
      Desalination would have taken place below the conn, although most fresh water was fed to the batteries.
      In regards to snorkels, it’s kind of hard to say. There was the GUPPY project post-war that upgraded and refit several Balaos to include things found on the German Type XXI, like snorkels for example. However I can’t recall a specific example of an American boat sporting a snorkel during the war itself. It might have been discussed within BuShips, but was more than likely discarded for its complexity and adding another water ingress point.

    Even a submariner can learn a few new things about their craft, thank you for this.

    Quality work! I was so excited to see this after the battleship video you did recently. Keep up the great work! Would love to see more sea-faring vessels!

    Great video. I have only spent time on nuclear powered submarines but the principle design has not changed much at all. Great basic explanation of what happens in every compartment. I was unaware of some of the things they had on these boats. I knew the current version but to see what they had to use back then is just amazing.

    I am at awe of the graphic illustration and all the time it must have taken to research all the information provided in the vid. Well done sir!

    thanks for this! I've been a submarine nerd for years and even tried to join the Navy as an officer aboard a sub in my younger years. I've consumed countless books, museum exhibits, video games, and movies on the topic. This was a pleasure to watch.

    Excellent video. The explanation of the gyro compass was the best non-technical one I've ever seen.

    Thinking this boats were designed and made a hundred years ago is amazing ! These machines are works of art of incredible complexity at a time when computers and everything we know today didn't exist. I am also incredibly in awe of all those engineers who were able to think of such ships on a simple drawing board AND build them ! This is equally true for ships such as the USS Yortown. Incredible "modern" aircraft carrier still today while the first drawings were thought in the 20s !!!
