It was not a 'new' weapon in 1944. BY November 1942 the British had over a 100 ships fitted with it and the kill rate had improved from 60:1 with depth charges to better than 6:1 with Hedgehog, which is partly why the Battle of the Atlantic had turned massively in the Allies favour by May 1943.

Depth charges don't have to make contact to sink a sub. It was best of you could get one below or beside the sub, rather than above it. The explosion pushes the water away at high pressure, but it can only do that laterally or upwards, not downwards with much impact.

Hedgehog mortars had contact detonators only (no hydrostatic pistols), so they had to directly hit something solid to explode. If they missed the target sub they wouldn't detonate until they reached the ocean floor.

This engagement was a great read. A few Americans won medals for keeping the sub afloat at great risk after the Germans opened an 8 inch pipe to scuttle her. That's why she appears so low by the stern in the video 4:00. You can see the American salvage team's whaleboat smashing apart on the heaving rear deck as they board her when the plane goes by. They secured the prized enigma machine, with code books, and the sub. One of the greatest intelligence windfalls of the war.

[@1chish]

With the greatest respect that is Hollywood bullcrap. The first Enigma machine and code books used by the German Navy in WWII were found by a Royal Navy Sub Lieutenant in May 1941 after HMS Bulldog damaged U Boat U-110 and the crew abandoned ship. Although a tow was attempted it sank off Iceland where the crew were landed having been kept below decks the whole time. They were told the U Boat had sunk without being boarded. The equipment on this American captured U Boat was the later one with an additional reel but again the Royal Navy had already captured one. What this film does not show is that because the code breakers at Bletchley Park knew where every U Boat was by mid 1942 the RAF had already straffed this U Boat and made it impossible to dive. Its position was known and the Guadalcanal group was directed to it by the intelligence from the UK. The Hedgehog weapon was also developed by the Royal Navy and proved massively effective. Having secured the U Boat the salvage crew did a magnificent job of bringing it to be towed. However the US Navy showed huge naivety in doing this and it was a directive from UK HQ that made them take it to Bermuda where it was disguised and hidden. Any details of captured U Boats had to be hidden as the Enigma secret was so valuable to the Allies using intelligence from Bletchley Park.

[@bodasactra]

@@1chish I know, thank you. I don't use movies for historical reference. On this event I refer to The History United States Navy in World War II. The 15 volume commissioned work by Samuel Eliot Morison. I appreciate British contributions as deeply as I do American. To be honest, its hard for me to differentiate them to a certain extent.

[@iatsd]

@@bodasactra Absolute bullshite. Enigma machines, code books, and Type IXC subs had all been captured 2-3 years earlier by the British. The sinking of U-515 - the subject in the video here - was simply the removal of 1 more sub from the German fleet. The Americans did NOT capture an Engima machine or codebook in this action. You're thinking of U-505.

[@anthonywilson4873]

Hedgehog was developed by the Royal Navy so you could keep eyes on with ASDIC. As Mortar bombs fired ahead of the ship only exploded on contact you did not loose the sub in multiple depth charge explosions or being so close to the target you lost it due to signal and return being “instantaneous”. 5 to 1 ratio five attacks on average to one sub destroyed as opposed to 80 to 1 with depth charges. ASDIC used sound to to ping direction and range of a submarine developed as a weapon in First World War era France and UK. Wikipedia is brilliant for research!

[@dovetonsturdee7033]

The weapon was invented by the Royal Navy in 1941, fitted to RN and RCN escorts during 1942, and supplied to the USN at the same time. RN and RCN escorts made 268 Hedgehog attacks during WW2, and achieved 47 sinkings, a ration of 5.7 to 1, compared to 60.5 to 1 from a 'normal' depth charge attack.

Henke was an exceptional commander, especially if you consider that he won his successes in 1942 and 1943, when the tide had already turned against the u-boats. He sank 25 ships with 155 000 tons, for which he was awarded the knights cross with oak leaves. His finest hours were a battle with an allied fleet during operation torch on 12 november 1942 (where he sank a large support ship and damaged a destroyer) and the sinking of 7 merchant ships from convoy TS-37 with only 9 torpedoes during a single night (30 april-1 may 1943). He also got in trouble with the gestapo because he protected an austrian family from them during vacation in tyrol. And he managed to save 43 of his crew at a time when most german u-boats sunk were lost without survivors.

The subsequent capture and towing of U-505 to Bermuda threatened to compromise Allied code breaking secrets and court martial proceeding were considered against the commanding officer.

[@jameshorn270]

I met a guy once who was wearing a USS Jenks hat. I had recently read Gallery book and asked him if he had been part of the operation. He had been in the third or fourth boat to arrive. the crazy thing was that Gallery almost got courtmartialed because they were afraid the Germans would learn that one of their subs had been captued intact, which would include an enigma machine, and they would almost certainly have changed their codes within days, the codes which the Brits were reading about as fast as the Germans.

Hedgehog was developed by the British and "Shared" with their Allies including the USA. Hedgehog used actively (In a developed form) amongst NATO Allies till the mid-1960's. After the War Britain developed the hedgehog into the "Limbo" 3 barrelled rapid fire ASW Mortar which was used into the late 1980's by Nato. Limbo fired multiple salvoes from a position Fore or Aft of the ship in a pre-programmed pattern. Limbo had many firing patterns and gave its captain the ability to select a pattern based on a specific situation.

[@bigbananna1616]

Absolutely correct .... not sure I get your point we were Allies you do that with Allies............ except the USA never paid for British war technology but Britain (And ALL US Allies) paid in full for the equipment they received through "Lend-Lease" with heavy interest (So heavy Britain only paid off its WAR DEBT in mid 1970,s) No problem with paying for stuff like that all the Allies were glad to do it but just call it what it is the SALE of equipment to an Ally that shares its technology with you for FREE.

Her Enigma machine & code books did not help to win the war. Gallery was almost sent to courts martial for not sinking the sub - it was just before D-Day & the Allies were very worried the Nazis would discover the capture & change the already broken coding procedures.

It was the sinking of U-515 the the task force commander Capt. Daniel V. Gallery came up with a plans for capturing a U-boat if the conditions were right. When they encountered the U-505 they were able to implement the plans and captured the boat. The bravery of the men that sized the boat can not be over played. The went on the boat not knowing if there was anyone yet on board or if the scuttling charges were set. Read the Captain's account of this in his book U-505, if you can find it.

[@sanseijedi]

Daniel V. Gallery was in command when they captured U505, boarding it & capturing an Enigma machine, if I'm not mistaken. Good writer as well. Check out some of his bibliography.

[@tomburton8239]

The "Hedgehog", so named because the empty rows of its launcher spigots resembled the spines of a hedgehog, was invented and developed by the British.

[@ernestclements7398]

One mistake the U boat involved was not the 515 it was the 505 captured by Admiral Daniel Gallery ( a Chicago native whose brother happened to be the commissioner of the Chicago Park District) he quickly gave the order the first time it was given Since the war of 1812 of Away All Boarders a boarding party got to the sub in time to close the seacocks and disable the scuttling charges, it was the first time that an operational Uboat was captured during the war, the boat was towed to Bermuda where it was hidden, and it's crew was placed under quarantine to conceal the fact that it had been captured intact, along with its code books, and it's enigma machine, after the war it was towed to Chicago, where it was placed alongside the Museum of Science And Industry, where it remained for many years before an addition to house it and other large exhibits was built, tours of it led to my nephews becoming a submariner in the U.S Navy.

If any of you want a really good read about the Allied effort against the U-boats I recommend "Black May." It's a fascinating read about how the Allies had to learn how to get the upper hand in the war against the U-boats.

[@hammer1349]

Being attacked by a hedgehog mortar could even be more terrifying than depth charges. You might not seen hear to mortars coming on sonar amongst the noise of enemy ships etc. Suddenly, your sub is rocked by a silent killer sea mortar round, with the enemy destroyer still behind you but still able to attack and keep track of you. The first encounter with a hedgehog mortar for the German U-boats must have been absolutely terrifying.

They used the Hedgehogs as inspiration for it. With how the pegs work in the IRL game, those look a lot like the Hedgehogs and they paired those designs for Alien Tech since pretty much nobody knows about the Hedgehogs. Kinda like how in Star Wars, they just took a ton of surplus WW2 weapons and added a black finish with some extra metal. If they can take something you might know, and tweak it into an alien object, it is cheaper than making it all up yourself.

Hedgehog and it's rival, squid, exploded on contact. A hit from hedgehog was a certain kill, unlike depth charges.

[@deathdragon2283]

Squid didnt explode on contact. It was set to detonate 25 feet above and below the target submarine. The depth could be changed up to the moment of launch. The resulting pressure wave would crush the submarine like a tin can

[@sirtristram8297]

The hedgehog pattern hit the water about 200 metres ahead of the destroyer. A ping from the destroyer's sonar has made a round trip of 400 metres when the echo from the U-boat is picked up by the destroyer. The speed of sound in sea-water is about 1500 metres/sec so there's about 0.25 seconds between the ping being transmitted and the echo being received. You had to measure that time very accurately to get the correct timing of firing the hedgehog, and allow for the time-of-flight of the mortar bombs in the air before they land in the water. And yet the hedgehog was surprisingly successful. It was later replaced with Squid, which fired two patterns, each of three bombs, ahead of the destroyer, one to port and one to starboard forming a hexagon about 200 metres ahead of the ship. Squid's bombs did not explode on contact; they were electronically set, before they were fired, to explode at the estimated depth of the U-boat.

[@geoh7777]

Torpedoes have to have a number of settings determined, entered into the equipment and the fish itself, and that takes measurements to target among other things, and time. Nearby vessels are moving at much higher speeds relative to the submarine, making the entire enterprise of shooting at nearby vessels hopeless.
