Did somebody sensible in Berlin figger he had longer experience at being defeated than anybody else, and this made him the most qualified to kiss Stalin in tuches? And he was ambiguously #3 behind Goering because the Luftwaffe might have beaten him out for First Place Loser?

Reminds me of my initial training as a P-3 acoustic operator. Spent many many hours listening to all sorts of audio recordings. Just as an FYI, these are clean recordings, with no other sources of noise. The situation gets really difficult when there are other ships in the area, especially naval ships. Destroyer types sound remarkably like submarines, having multiple propellers with frequent speed changes. Most merchant ships have a single propeller and will maintain a steady rpm for fuel efficiency.

Baiting tactics were standard procedures for Coastal Command as promulgated in Coastal Command Tactical Instructions No 22 in March 1942. Sonobuoys were not involved at that time and a smoke float was dropped at the swirl point as a marker. After that it could hunt for no more than 15 minutes then the aircraft would withdraw at least 30 miles for 15-30 minutes before returning, ideally using cloud cover.

The thumbnail of the PBY was the bait that got me to the surface. Goodness gracious I love that airplane!

It was seriously over budget and behind schedule at a time when the manned bomber was being replaced by ICBMs so the Eisenhower administration cancelled it. It was the last airplane Martin would build. Currently Lockheed-Martin is developing a float equipped version of the C-130 for the Marines and SOFs, though the US Navy has been seen poking around the ShinMaywa US-2 seaplane as a possible off the shelf buy but are not crazy about how the Japanese deploy inflatable boats from their airplane.

My Dad was a squadron commander in the 8th Air Force based out of England. Before that he was involved in lots of B-17 training throughout the US, including sub patrols in the Gulf. One time, while in his B-17 he came upon something floating on the surface. After first seeing it, he figure it for a citrus crate, but then soon realized it was a sub. He took a straight bearing on the sub that was going away. He marked a fly spot on his window and lined it up on the sub. He then used the geometric principal of equal triangles to head his B-17 right over the U-boat. Their pictures show that they dropped their depth charges in a pattern that straddled the sub's wake. This all happened within a few minutes. After bombs away, Dad called back to the training instructor who was taking a nap in the back & told him what had happened. He got really ticked off that someone hadn't thought to stir him awake. You snooze, you loose, is how I figure it out. On D-Day, Dad was deputy lead of the 1,400 or so B-17s & B-26s that hit Normandy.

Another tactic was to blanket the surface where a U-Boot was suspected with a green paint or dye (formulations changed as the war progressed). When the sub commander upped periscope to look around prior to surfacing, this dye would foul the lenses. Believing himself still submerged, the commander would continue the ascent until, at an altitude of 500--1500 feet, he became a sitting duck for antiaircraft fire.

GREAT RESEARCH

In the late 1960's I bought two surplus sonobouys in Vancouver, B.C., Canada. They contained a saltwater-activated battery, a pc board with discrete components, a transistorized FM transmitter. Frequency about 162 MHz. Estimated output at 12 volts, Ham usage; I don't know what the battery's voltage was, about 1 to 2 Watts. These were converted by Hams, (Radio Amateurs), to the 2 meter band, 144 to 148 MHz. One of my bouys contained a Fuchine (coal-tar derivative?) coloring, reddish purple, agent which disolves and spreads in water. Stained the whole hippy-pad! Peace Man! The microphones were not available. Antenna was about 18 in. like a ribbon tape measure; vertically erect, 1/4 wavelength. No sign of parachute. Several years later I saw a type with directional sensor, (magnetic compass surrounded with a number of coils). That was classified stuff back then. Sorry no other info on that. Was the microphone fixed with regard to the bouy? It was obvious that a pattern of these using different frequencies would allow position fixing and course plotting of anything noisy, moving below the surface. Checkout magnetometer equipped aircraft; Argus, Orion. Technological advancement thrives on inspiration. US army manuals and Heathkit are really good, better than most schoolbooks! Learnt a lot from them! Thank you author of the Sonar bouy info.

The Navy had 2 primary aviation "ratings" (job specialties) wholly concerned with ASW (Anti-Submarine Warfare) when I was in in the 70s. There were the Operators (AW), and the Technicians (AX). The operators flew and used the gear, and the techs maintained the gear, (mostly on the ground, but they would usually take a "tweetie-bird" on missions to fix stuff in flight.) The Navy LOVES teaching history, and any school you go to for training is likely to begin with a history lesson to put what you are going to learn about in context. As an AX (Aviation Anti-Submarine Warfare Technician), I do remember being taught about the FIDO, but I do not remember any mention of legacy sonobuoys, which in WWII had to be vacuum tube based with complex multi-voltage power supplies and undoubtedly a lot of maintenance and coddling required on the ground. This confuses me. Were you AWs (operators) taught about sonobuoy use in WWII? I can kind of understand them not mentioning them to new techs (why waste time on a painful memory), but I would think operators would get the full history treatment.

How were Bomber and Flying Boat search patterns configured ? I read that often on North Atlantic search and destroy missions against U-boats, planes used a segment of a circle pattern. This looked like a triangular piece of a (very difficult !) cake, with the "point" being their air base and the widest part being their last pass along the "basis" of the triangle, before returning to base. Planes would be making horizontal "loops" between the "legs" of the segment to cover more sea surface. I do not know if the same "weaving" pattern within the segment was used on their home trip. Or was the making of 'loops' left to the outward bound plane relieving them ? Because early radar sets were unreliable, possibly an optimum altitude, enabling both eye ball and radar detection, was used. What alltitude was chosen as a rule ? How much was the distance between the search "loops" and did flyers use a stop watch to help making course changes ? AND: Could this be the subject of a new tube ? It would be great I think ! Your work is unrivalled ! MANY THANKS !

The sonobuoy pattern he showed with a corner buoy and then three more sonobuoys in an L shape are the same as we learned in the SH-3G Fleet Replacement Squadron. I ended up on a search and rescue unit so I never got to do ASW in the fleet but we trained on it learning to fly the SH-3.

Submarine sonar operators can hear sonar buoys hitting the water. Ideally drop them just as it’s gone under. They’ll be less likely to hear them hit the water.

They taught us in Latin class that "Semper ubi sub ubi" meant "Always wear underwear," but this was a lie. It means "Where are the submarines?"

Could they detonate an EMP under water, and it still be equivalent as if on the surface?

Lamar’s patent was RF-frequency hopping for use in radios (not sound). Applying this to a radio controlled torpedo was a problem for two reasons; 1) In WWII the US did not have a radio controlled torpedo as the propagation of RF through ocean water is notoriously poor, and 2) the last thing a submarine would want is to be required to broadcast, for several minutes, an RF signal to the torpedo that everyone around could detect and get a fix on. That’s where Cutie was great as they guided themselves - “fire and forget it” with no traceable link to the sub. BTW: Your story is that Lamar could have saved 100’s (1000’s?) of sailor’s lives but because the government didn’t offer her enough money she withheld the patent rights? That sounds a bit mercenary. The FACT is, as an Austrian opposed to the Nazis, Lamar offered the use of the patent to the U.S. government as a gift. Free of charge to support the war effort. But because the government had no practical use for it they declined the offer. Later the idea was used for jam-resistant radios, unrelated to torpedoes.

The Soviet Whiskey class was re-designed before the first units were built based on knowledge gained from captured Type XXI boats. Their design was heavily influenced by the Type XXIs. Probably the fullest expression of those lessons is the Foxtrot class. However the superiority of the teardrop hull form used on the Barbel class and its Dutch and Japanese derivatives made the Foxtrots obsolete before the first boat was commissioned.

Bouy.

America lost so many ships because coastal towns and cities refused to have night time blackouts so merchant vessels although blacked out were silhouetted against the lit up shores and were easy targets for u boats.

So, it was not the convoy system responsible for the high kill rate of the German U-boats, but rather the tactics of ant-sub aircraft such as the US SPY using sonars from buoys, and subterfuge, pretending to fly off, only to return 30 min later to find the sub on the surface. If the sub had been diving for more than 15 s from a surface position, it was safe and the plane unable to destroy the sub.

He didn't say that. The convoy system was to overwhelm the numbers of U-Boats with escorts that could force the U-Boat down. Since the Germans had a fascination with deep diving, these subs couldn't possibly surface fast enough to continue pursuit of the convoy. We encouraged them to feel superior because of the deep diving characteristics of their U-Boats. In reality a deep submarine was completely harmless and permanently out of that particular fight. As numbers of allied escorts increased, hunter-killer groups, not even necessarily assigned to guard convoys, were tasked with finding and killing the U-Boats. The hunter-killer groups were the end of the U-Boat as an effective weapon. Usually a hunter-killer group was centered around a jeep aircraft carrier and very different tactics than this luring U-Boats to the surface.

@@RockinRobbins13 Rock&Robbin -- Neither did he deny that! From what you said, it is still unclear if the demise of the German U-boat was primarily due to a ship escort or due to anti-sub aircraft. I suspect it was a contribution from both sources, but I stand to be corrected by anyone in the know.

@@LaHayeSaint The nasty secret of the Battle of the Atlantic is that the very moment the first U-boat fired a torpedo at Atlantic shipping Germany lost the war. Submarines were not an appropriate weapon to use against Britain. Their use guaranteed German defeat.

The main mission of convoy escort is to protect the convoy. Killing subs was a distant second. Once a sub was forced to dive, it was no longer a threat to the convoy. And a convoy could easily avoid the area where a sub was spotted.

@@stevenpace892 That's fine and was the initial strategy. But what ended the U-Boat war was the jeep carrier based hunter-killer groups that were not tasked with guarding convoys, but solely with hunting and killing U-Boats. Yes, there were escorts around convoys. No, they didn't win the U-Boat war. It's interesting that the Germans took great pride on how deep their U-Boats could dive, oblivious to the fact that a deep diving U-Boat was absolutely harmless. The time it took to regain the surface after their standard deep dive was the time the convoy used to leave the scene and be unreachable ever again for that deep diving U-Boat. The US learned lots from the failed U-Boat strategies and used that to defeat the Japanese in their own submarine war. Their "be dangerous" strategy was much more productive than the Germans' "dive deep" gambit. However, the very use of the U-Boats for unrestricted submarine warfare against merchant shipping was an absolute guarantee of defeat for Germany. British goods came on ships belonging to other nations. Sinking those ships brought the entire world into the war against Germany, absolutely guaranteeing German loss of World War II. Of course, Germany made multiple fatal mistakes, any one of which absolutely meant they could not possibly win. U-Boats talking like a bunch of school girls was another one. Their handling of the Enigma code was another.

What a horrible way to die.

I disagree, I really like the extra info and where it comes from as it's presented. It's different from other channels

It’s pronounced ‘sonar boy’

My Uncle was part of " Operation Emerald " in the Atlantic . Top Secret until 1986 . During the Atlantic attacks on the convoys my Uncles job was to detect U boats using the ASDIC system . Once the sub was located it was circled by a frigate which poured oil based green paint onto the surface of the water . All craft would then kill their engines and wait . As the sub put up its periscope , it's lens would be coated with a layer of the emerald green paint . The sub commander would assume - due to the colour that he could see through his periscope eye- price that he was still submerged . I asked my Uncle what happened next and he said that the U- boat would keep rising up . He said that when the sub was three hundred feet above the surface of the water , they'd shoot it down with triple 'A' ! : )

11:25 While I found your video to be very interesting, especially from a technologically historical perspective I would believe myself to be "ethically challenged" if I started to "enjoy" your videos. When one realizes that the people on the target submarine are probably the most terrified that a human being can be without falling into a state of shock or unconsciousness and that the sounds that you are hearing are the sounds of over a hundred people meeting their death I have to admit that I am pretty soft when it comes to morals and ethics and anything that has to do with war fighting and specifically death leaves me feeling appalled, especially with regard to the sheer waste of life and the grief that their families must experience. Certainly from the western perspective everyone got what they had coming but still we should never enjoy war. I realize that you likely don't intend to convey such thoughts and its probably the nature of the shortcomings of language that we do face from time to time as it becomes apparent and I thought that it would be a good idea to let you know that if I went only slightly sideways upon hearing such a statement then there may well be some who quite possibly get "wrapped around the axle" when they hear such things. Sorry if I sound like "Neil" from "The Young Ones" on this but I just had to say it. So fair winds and following seas.

I've known two men that flew on different parts of our east coast on sub patrols, both said after while , they would see sub periscopes everywhere, even in their sleep. It must have been nerve-racking for guys in their late teens and early 20's to have so much responsibility knowing how many ships and sailors would be lost if they didn't do their job well

U boats were a threat in the Gulf of Mexico for about six months during 1942, and only one (I66)was definitely sunk during that time and was only identified by Robert Ballard and his crew a few years ago. The discovery was later televised on National Geographic. U boats prowled the Gulf in an effort to harrass and/or stop the tankers bearing gasoline and other fuels. From Texas refineries, they sailed from the Gulf and around Florida, to supply the war effort in Europe. C.J. Christ, of Houma, Louisiana, compiled research from old newspapers, naval archives unclassified well after WW II, and interviews he held of veterans of the war. Christ's book is available at the WW II museum in New Orleans or at the Tri Parish Military Museum in Houma. Other battles in 1942 drew more attention, but for the Louisiana shrimpers, it was a dark and dangerous time.
