The Super Weapon that Turned German U-Boats into Scrap

  • A secret research endeavor under the direction of the British Admiralty led to the development of a unique weapon that would change the course of maritime warfare during World War 2. The result of trial and error, this anti-submarine projector turned the tides against the Nazi U-boats and wreaked havoc in the Pacific.
    Instead of dropping depth charges on submerged submarines and causing damage from hydrostatic shockwaves, a different approach to outperform them was conceived early in the war. The idea was to design a device that would fire spigot mortars ahead of a ship and have them detonate only when they hit a hard surface.
    Though the original Fairlie Mortar device was unsuccessful, a new idea sprung from the misadventure, and thus the Hedgehog was born.
    Named for its rows of launcher spigots which resembled the spines of the creature when devoid of a load the Hedgehog would not only redeem the Fairlie but become one of the most feared weapons against the dreaded German submarines...

    A nice piece. The Hedgehog really was revolutionary. In addition to solving the problem of the sonar blind spot when the destroyer passed over the sub to engage with depth charges, it also eliminated the extreme danger those depth charges posed to their own ship when dropping them. The destroyer had to be running at full speed, otherwise the same hydrostatic wave expected to kill an enemy sub could and often would shatter the destroyers rudder, steering gear and prop shafts. Leaving the ship crippled and easy prey. The Hedgehog let the destroyer put the much smaller explosions well forward of the ship, such that the bow could easily handle any minor shockwaves, instead of taking the force to the rear.

      My dad served on, I believe a DE, as a carpenter mate. During a depth charge run an officer asked him why he was forward from his position. About that time the stern lifted out of the water from the depth charge going off. Answered.

      Incorrect. Considering the exact sane depth charges were used in the same ways by everything from 16 knot Flower class corvettes to 36 knot Fletcher class destroyers, they could not all have been running at the very same "full speed."
      A very serious problem with depth charges was that a sinking destroyer, DE, corvette, and so on would end up with most of the crew that had abandoned ship dying from concussion as the depth charges of the sinking ship exploded at their preset depth level. I have read of this in many cases.
      Also, I believe Admiral Jellicoe of WW1 Grand Fleet fame is credited with the development of the depth charge during that war. Before the RN deployed depth charges, the best hope for sinking U-boats was direct fire, ramming, and undersea mines.

      @@amerigo88 You're quite right there, full speed was nothing like a requirement (and every corvette being one-use-only at 15kt is a bit ludicrous!), and usually ASDIC/sonar performance dropped off a lot with speed so if you barreled around at 35kt you'd not be detecting much anyway.
      There were some occasions where you could damage yourself, especially dropping a shallow pattern and in shallow water, but that would typically spring your stern glands and cause some shock damage, not shattering the whole propulsion set. I remember USCGC Icarus managed to prang herself fairly badly in shallow water off the US, but not too many other examples.

      The problem was that becasue Hedgehog was so badly needed and so innovative it was mass produced, stuck on a lot of warships but there werent enough trained officers who could go round the fleet giving training.
      Many ships basically got a new weapon and an instruction book. Good ships or technically minded crews learned fast, the less able ones didnt.
      Add to that rapid installation by dock workers who didnt have a clue what they were doing meant the launchers were misaligned with the ASDIC which added to the fact gunners unaware of the flight and sinking time and the launcheers not being maintained so the swing and aiming gear rusted solid on inept ships meant they launched off rounds, got no bang and assumed the weapon was defective so they lost morale and any urge to use it.
      Good crews on the sub-hunters tended to be used well, the random convoy escorts tended to be less effective.

    An excellent presentation on a game changing weapon system.
    The principle behind the 'Hedgehog' ASW mortar is still in use today in more modern applications, primarily in Russian and PLAN destroyers and frigates because it works. Most Western navies prefer other weapons relying on homing torpedoes.
    USS England (DE 653) and most other destroyer escorts were fitted with a single Hedgehog launcher while many Fletcher, Sumner and Gearing class destroyers mounted two. In both DEs and DDs this was in addition to their depth charge racks and "K gun" depth charge mortars.
    At one point after USS England became a seagoing "Ace" (5 kills makes a fighter pilot an Ace) Fleet Admiral King remarked "There will always be an 'England' in the United States Navy. The next England started life as a Leahy class Guided Missile Destroyer Leader / Frigate (DLG 22) but was later reclassified as a Guided Missile Cruiser (CG.)
    I think it's past time for the USN to build and commission another England.

    Whenever an hydrostatic depth charge went off the water was disrupted so badly for several minutes that they frequently lost their ASDIC/SONAR contacts in the broiling, bubbling mess. Subs could make their escape using a dramatic course change in the confusion that was undetectable. A big advantage of Hedgehog and it's contact fuse is that a "miss" did not result in an explosion and therefore continuous contact was maintained throughout. If there was an explosion ... you got 'em and it doesn't matter.

They had damaged a U-Boat with their hedge-hog mortar, and had been following the oil trail for a couple of hours. Then a British destroyer showed up and ordered them to get lost and let "the professionals" handle it. So guess what happened. "The professionals" managed to lose the U-Boat. The next day when they were in port, the crew read about a surfaced U-Boat trailing oil being sunk by a patrol plane right where they had been ordered away. Dad said the captain was furious over the incident.
    And though it was 50 years earlier, I could still feel the bitterness in dad's voice while he told the story. He said the hedge-hog was a huge improvement over depth charges. Main advantage was that it was facing forward. Could also be used against surfaced U-Boats.

      to be fair, the Royal Navy in general had the most experience in dealing with Uboats, much more than the Canadian or US Navy. So I guess that was where that arrogance from the RN captain came from. Of course averages are just that, averages, an experienced Canadian crew of course performed much better than a green british crew, but on average the RN had the most experience. Also, Uboats that got trailed were lost all the time again, so it may be possible that the boat your father was on would have lost it as well. We just dont know.
      On another note, I always find it funny how the US basically refused any advise from the Royal Navy in how to deal with Uboats after their entry into the war, leading to another golden hour for the german uboats directly off the coast of the US. A big part in that was that no blackouts of coastal cities were done, as a result the merchant ships were visible against background light at night, making much easier targets. A lot of ships were lost because the USN was too arrogant to use the strategies the Royal Navy suggested to them.

      My dad was a submariner during WWII as well, and talked very little about it as it instilled in him fears that his son would have to go to war someday as well. We'd go through the U-boat at the Chicago Museum of Science and Industry, and he'd note things in the German sub, comparing it to the U.S. subs. Even berths would make him state, "Man, we had it a lot better than they did" about U-boat crews, but he always had respect for his fellow submariners, even the enemy. It takes a certain type of person who is able to keep a straight head when others would be losing theirs to serve on a submarine.

The USN codebreaking units were responsible for the Northern and Central Pacific. British codebreaking units, based in Colombo, were responsible for Burma and the Indian Ocean. The Australian codebreaking units, based in Townsville and Darwin, were responsible for South-West Pacific including the Solomon and Admiralty Island chains, New Guinea, and the Dutch East Indies. The Australian codebreaking units were integrated into the FRUPAC command structure which resulted in their work being reported as USN successes. USS England's anti-submarine operations were conducted within the Solomon and Admiralty Island chains and the responsibility for codebreaking would have been with the Australian codebreaking units.

    ~1969 I served aboard the U.S.S. Nicholas - DD-449 out of Pearl. She was the oldest DD in the Navy at that time. After her final WestPac tour we were tied pier side to undergo her decommissioning, I was an FTG in gunnery division. We had Hedgehog racks forward and above the main deck splash guard. Below the bridge, and below the Gunfire Control Director. The Hedgehog racks were loaded with dummy sand filled charges painted blue. While doing PM up in the Director, all hatches open for air flow, I heard the distinct BRRrrrraap of the hedgehogs firing, I glanced up through the director top hatch to see a salvo of blue hogs in flight up and away. Towards the pier.
    Stuck my head out of the open hatch to see the hogs pummel the pier, and the geedunk restaurant stand on the pier.
    No injuries, the geedunk stand sheetmetal patio roofing took a direct hit by at least two sand filled hogs and collapsed.
    The next issue of the "All Hands" magazine had a lead article about how the Nicholas had sunk a geedunk stand.
    I carried the magazine around for the remaining three years of my enlistment. Always good for a smile.
    Oh, no campaign ribbon was issued for the battle of the pier.

The projector was elevated by hydraulics adapted from the Logan traversing mechanism used in M3 Medium tank turrets and electrically fired either individually or in a salvo of six, from the 12 o'clock position;] the fifth tube could not be fired until the turret was traversed to 1 o'clock, to move the radio antenna out of the bomb's flightpath. Each bomb weighed 65 lb (29 kg) and contained 30 to 35 lb (14 to 16 kg) of high explosive. The range was up to 400 m (440 yd). Aiming was accomplished by pointing the entire tank; the mounting had no independent traverse, so accuracy was not spectacular, but adequate for the task.[40] Trials at Southport, Queensland, in May 1945 were pronounced complete success, and the Projector would have been impressive against enemy bunkers, but the war ended before it was used operationally.

They would blow out light bulbs and cause other electrical issues when they were fired. Ripple firing hedgehogs only reduced the amount of damage. Look up "mouse trap" ASW projectors used by smaller ASW vessels due to the huge reduction in recoil. Mouse trap had some issues with the back blast but this was manageable.

They then told him to take it off the launcher and throw it overboard. He hated that as he wasn't sure if it armed itself.

Big barrels used for depth charges could be heard, but the smaller mortar was more diificult to hear. If ship went over a sub it was good idea for the sub to change direction.

You can't really tell when a ship fired hedgehogs and hedgehogs did not explode unless contact with the sub, so you can't hide in the aftermath of the explosion.

    Your so called "blind spot" was when the submerged sub got close enough to the ASW ships that it was below the acoustic energy beam that was projected and received at the sonar dome. The farther away sonar lost contact the deeper the sub was submerged. This allowed the sonar gang to calculate the subs depth and call out settings to the depth charge crews. Sometimes also the ASW ship would use it's fathometer as it went overhead the sub to find the how deep it was submerged and call out depth charge settings. The amount of time the sub was in your so called "blind spot" was usually not enough to allow it to escape. When the subs sonar couldn't hear the ASW ship pinging any more is when they would try to avoid attacks close enough for a kill and if they got lucking make an escape. Keep in mind that usually ASW ships operated in mutually supporting groups and this made escape difficult for subs in WW2.

    Thanks for posting this. Have not seen much on TH-cam reference this weapon.
    Did not realise that Stuart Blacker was involved in developing this.
    I knew that he had early involvement in what went on to become the Infantry PIAT, after further development by Millis Jefferis of Ministry Defence 1 (affectionately known as Churchills Toyshop).
    I had assumed that this was only used by the Royal Navy, and did not realise it was adopted and used as it would see to great effect by the American navy.
    Love the channel, keep the content coming.

      It was also used as a "bunker busting" weapon fitted to the Churchill tank. Called the Churchill AVRE, one of Hobarts "Funnies" that was part of the 79th Armoured brigade, it featured a 240mm petard mortar replacing the main gun, fired on the same principle as the hedgehog, but used to blow up bunkers on the beaches during D-Day. If you want to know more about the development of these weapons and the men who came up with them, I recommend reading "The Ministry of Ungentlemanly Warfare: Churchill's Mavericks: Plotting Hitler's Defeat" by Giles Milton

      The Allied forces that hit Juno, Sword and Gold, all had "Funnies" supporting the assault, so that would include the Canadian divisions.The Americans were offered the use of all of them, but only chose to take the Sherman DD's, but they were launched too far away and in the wrong place, forcing them to try and cross the prevailing tide, which swamped a lot of them. How much of a difference it would have made to US casualties on Utah and Omaha, if the "Funnies" had been fully utilised, is something that is unknown.

    I greatly enjoy these tidbits of history that I have not heard of before. One thing I would like to know about the hedgehog is what happened to the rounds that did not hit a hard target and explode? Is the sea floor littered with unexploded hedgehog rounds just waiting to go off? I know that there are modern versions of this weapon in use today but they have delayed detonation safeties installed on them in case they don’t hit a target. I think some of the Scandinavian countries are using some version of the weapon on their coastal patrol boats, but I don’t know who else is using them. Does anyone know when the last time the hedgehog was used in combat was and against what enemy?

    • @AVB2
      @AVB2 2 ปีที่แล้ว +20

      World War Two was the last war that the Hedgehog was used. Weapons derived from the Hedgehog have been largely phased out from Western navies in favor of homing torpedoes.
      These rounds were made from mild steel which is susceptible to rust once the paint is removed by wave and sand action on the outer skin. Once the outer skin rusts through the Torpex (explosive) would simply dissolve. After nearly 80 years of being submerged in saltwater any unexploded Hedgehog rounds have most likely already been naturally defused. In addition they are laying in the ocean hundreds or thousands of miles from where divers could disturb them.

    The Hedgehog 🦔 and the underwater radar, sonar, were the game changers that doomed the U-boats as an offensive weapon. By the end of the war, a U-boat was lucky just to return to port after her patrol. After 1943, it was ' Hell in the 🌊 sea ' to be in a U-boat. The thing was, if the Germans had built 👷 a lot more of the U-boats instead of wasting it on surface warships before the war, they would have knocked England out of the war.

Moreover, the Admiralty never expected to be required to fight against Germany and Italy unsupported by the French fleet. As a result, the Royal Navy was much more stretched than any pre-war planning had assumed.
      When you also include the fact that the German submarine fleet was never expected to have had access to French Atlantic ports, but was assumed to have to make the long voyage around the North of Scotland even to reach the Atlantic, the need for any 'catch up' was not surprising.
