Four Fun Facts about the Oerlikon 20mm Antiaircraft Cannon!

Sold for $23,000 (transferrable).
The 20mm Oerlikon automatic cannon was a mainstay of United States naval air defense during World War 2, and today we will look at a few of the characteristics and questions that apply to this sort of automatic cannon but not to typical small arms. Like, for instance, how do you cock a gun that has a 400 pound recoil spring? Or, what happens if you fire a high explosive shell into your muzzle cover?

    Would getting planning permission to use a Howitzer for an in-ground pool not be prohibitively difficult? I would think that the neighbours would raise concerns about periodically excavating the pool (crater, w/ explosives) instead of having a permanent install-- ah, I see. After the purchase they could well be less reluctant to deny permission to construct permanent features.

    I think it would be a good investment in the long run to get the Howitzer first and then make a pool with it with craters because a pool cannot make a Howitzer. This way, you could make a business by making pools for people by shooting Howitzer shells in their backyards. It might be a good idea to use yellow caution tape around the target zones so people know where not to stand while their pool is being made.

    It was one of these weapons Edward “Teddy” Sheean used to earn an extremely overdue posthumous Victoria Cross in 2020 for his bravery in WWII onboard HMAS Armidale by shooting down one Japanese aircraft and damaging at least 2 more while injured. His shipmates had already abandoned their sinking ship and were being strafed by the Japanese, and it was reported he was still firing as he slipped beneath the waves. He is now the only member of the Royal Australian Navy to have earned a VC, and the only junior sailor in the RAN to have a major combatant named after him, the Collins class submarine HMAS Sheean.

    It also makes me suspect that being an anti-aircraft gunner on a warship was not a fun job. At least this gun has a somewhat proper magazine, there were also guns with just 15 rounds. And the whole ship depends on you and a few of your still living colleagues while you're busy hauling the bolt back into firing position. Much respect, but I'm glad I have another job.

    My Grandfather was a skipper for a mine-sweeper with a few of these on it during WW2 and they had a near tragedy with the muzzle cap because not only did someone forget to remove it, the magazine actually didn't have the inert rounds in it. However, the HE round didn't actually explode passing through the cap because its fuse was faulty, so it managed to get a few hundred meters before finally half-exploding. Once in a while, things go so wrong that the worst wrong is cancelled out in the process...

    Thanks for the great video! I just finished re-reading Alistair MacLean's excellent WWII naval battle classic "HMS Ulysses". The book vividly describes the Arctic convoy runs from Iceland to Murmansk and this gun shows up many times as the heavy cruiser tries to ward off German bombers and dive bombers. One of the gunners does, indeed, blow up his gun by firing an HE round with the cover iced up. Reading that book gives one a whole renewed sense of respect and even awe at the men in the British and American Navies and the men who served as Merchant Mariners.

    AFAIK the nearest that the USN got to a convoy going to Russia was when the USS New York was part of the distant cover for one convoy. She was withdrawn soon afterward and assigned to one of the Pacific fleets. The USN built ships to operate in the Pacific and they were totally unsuitable for the North Atlantic and Arctic Oceans. BTW I am not trying to stir up inter Navy rivalry. If my understanding is not correct please feel free to correct me. Back on the subject. On one ship that I served in the Chief Petty Officer Gunnery Instructor hated the Oerlikons but reserved most of his spleen for the 'Chicago Pianos' but we shared a love affair with the Bofors and the ubiquitous twin 4".

    I served 11 years in the Royal Navy and one of the ships I was on was a minesweeper in the Persian Gulf and this ‘sweeper had a double barrelled Oerlikon mounted just abaft the funnel. The firing position for the aimer was on the left of the mounting with both guns on his right-hand side. One day when the squadron was at sea it was decided that a practise shoot was needed, the first time the Oerlikon had been fired since I'd been onboard. One of the ‘sweepers towed a splash target and as it passed, the other ‘sweepers steaming line astern opened fire on the target as it came to bear. Our gunner opened up on the target and the left gun jammed, the gunner looked over his right shoulder at the gun saw that the next shell in the magazine, which was a tracer, had somehow been activated and was burning in the magazine. He calmly unshipped the magazine and threw the whole thing overboard before any more rounds in the magazine caught fire. The he threw that magazine a distance of about 15ft, straight over the side, which was a fair feat of strength because those magazine are not light when they are empty but full of rounds they are weighty piece of kit..

    Had these on the Viet Nam PTFs. 1 each on port and starboard. I was a loader on my first PTF and the snail mags were really heavy for a skinny 20 year old. The big risk was a hang fire - if it blew it would take the whole mount (and crew) out - unscrew and throw over the side. If you were lucky.

    The 20mm was effective in US Navy service until the Japanese resorted to Kamikaze tactics late in the war. It could not stop Japanese aircraft on a crash course. Navy personnel above decks knew "When the 20mm kicks in, that's when it's time to hit the deck," and crew members below decks knew it was time to close off the air intakes to avoid the fire from the Kamikaze strike from being drawn into them. Even the 40mm Bofors guns had a hard time stopping the Kamikazes. They were replaced by a 3-inch AA gun shortly after the war, and the 20mm was removed entirely. Still, a great weapon up to 1945.

    That weapon was a gamechanger for light naval AAA ,setting the standard for most of the war. By 1944 however the 20mm Oerlikon was considered to be too light to deal with air threats (particularily so Kamikazes), and more emphasis was put in the Bofors as the baseline for light naval AAA defence. When are you going to get the chance to do a video about that one? ;). And...that's some amazing job you have Ian, will never stop repeating it.

    "When compared to the Oerlikon cannon which was made out of 250 parts, the Polsten was made out of 119 parts, without sacrificing the effectiveness or the reliability of the cannon. Simplification of the design of the Polsten cannon made its production much cheaper. The cost of one Oerlikon cannon was about £350, while the cost of the Polsten was between £60 and £70. In January 1944, the 21st Army Group decided that only 20 mm Polsten guns would be used as a standard light gun to simplify supply. The Polsten was used as a substitute for the Oerlikon in the same roles, one of which was as an airborne unit anti-aircraft gun, used in Operation Market Garden. It was used on a wheeled mounting that could be towed behind a jeep. " Polsten is only 57 kg (126 lb)... and why swiss would be selling pre WW2 guns when USA was most likely full of this type of ex-WW2 equipment?

    Thank for you posting this video. My father was a GM3 on the S.S. George W. Childs and was primarily assigned to the 20MM Oerlikon. He was aboard the Childs at the Normandy invasion. The Childs was deliberately sunk in the sand as part of the artificial breakwater for Mulberry A. My father and the rest of the crew were aboard the ship for two weeks before heading back to England. He's 92 and still sharp. I asked him about the manual for the Oerlikon. He says that he never saw one. He was trained at the Brooklyn Armed Guard Center. Armed Guard crews were pretty much on their own after that. He was aware that if a shell got caught in the breech, he had about a minute to clear it before it would explode. Fortunately, that never happened. Thanks again for the video. My father will enjoy seeing this!

    The model we used had cocking arms attached to the base. You would domp the gun and attach those arms to the lugs on the front side of the action-arms; then you would use your body-weight to raise the muzzle and while doing this the cocking arms would pull the action-arms back and cock the cannon. Extra fact: the last rounds out of a magazine need to be shot as a burst; if you try to single-shot these rounds, the spring in the magazine wasn't powerful enough to feed the cannon when said cannon was going up, down and rolling left to right on a moving ship.

    The MG-FF is absolutely not the same as this Oerlikon! Sure, both were developed from the German WW1 era Becker gun, but that's where the similarities end. Both guns have completly different uses; the MG FF was a dedicated aircraft gun while this type of Oerlikon was a dedicated AA gun. Oerlikon made 3 models of 20mm guns, each having different casing lengths. The Oerlikon FF had the shortest casing and was the base for the development of the MG-FF and the Type 99 model 1. The Oerlikon FFL was used as a base for the gun in this video and the Type 99 Model 2. And the Oerlikon FFS (the longest of the three) served as the base for the Hispano-Suiza guns used by the British and the French. Impressive guns, all of them. Something about a big ammo drum on the top just seems more badass than a belt hanging on the side.

    for dummy rounds I can't imagine it's too much work, I actually have an inert one on my desk.

You have to create a proper storage set up for explosives and prove it in inspection, and of course you need to have an explosives handling license which is really hard for civilians to get after the bath school bombing. You have to pay a 200 dollar stamp tax for it, and I when I say for it I mean per round. There's also a ludicrous amount of regulations, i'd love to go into detail about them but you know youtube comment and all that. of course the problem you'll run into is absolutely no one will sell you explosives since if you decide to go full jihad with them it's on the seller. So really the only way you're going to get explosives is if you're a well sourced FFL holder or a LEO, and that's only a maybe at best. Also being a millionaire would help.

    That's why I think the firearms act was created by ATF agents, they want to keep all the cool stuff to themselves.

    Jerry Long No not really. If you can actually get all the licencing and the permissions (as well as the actual destructive device), then you could go and use them at your leasuir. Don't take my word on that though.

    Man, I would blow the NFA vetting for this gun for sure. I would be unable to stop myself from writing "anti-aircraft defense" in the "what in the world do you want it for?" blank on the form, and the ATF hates a smartass.

    Hey question for Ian or anyone that can answer. Is there a rifle or firearm that is open bolt, but does not have a bolt carrier (thus just has the bolt contained by the receiver). But also is lock breaching and operated through a gas piston. Because i can't think of one that has such a set up, but at the same time i highly doubt i came up with a new set up.

    That is kinda the plan, to have a video series that goes over the design and pretty much the whole process (thou still working rough sketches, and will be on a side channel). Also it's an select fire air rifle design meant to fire your average 12.7 nato bullet as well as cast bullets. But also look, feel, and operate like a normal rifle, well being useful for hunting or self defense. Which is all a pain in the ass to pull off, but that's why i'm doing it. Since it forces me to learn more information and think of new ideas, so I become better. Also i do plan to make a cartridge version, after the air rifle one. Because firearms are mechanical devices that have always fascinated me. Which is why I said i kinda want to relearn the swim using some concrete shoes. So I have to struggle and work to get there, thus when i do end up designing them again. I am at a level that i know will produce quality.

    I qualified as a mount-captain on a 20mm Mk-16, which was the heaviest flexible-mount weapon on USN units from the '70s thru the mid '90s. It was originally an aircraft cannon (A-1D Skyraiders carried four of them) but was adapted for shipboard use out of necessity, I assume. It had many of the features of the Oerlikon, with the exception of the feed system, which was a rotating, five-stage carousel driven by a cam powered off the recoil of the bolt. It required an insane amount of oil to keep it running, including a large reservoir that had to be refilled regularly. It was charged by using a 3/4 inch ratchet to turn the carousel until a round dropped through the receiver and onto the deck, but only after the gunner used a foot-stirrup to simultaneously push down with his foot while pulling up on the grips like he's doing curls at the gym. once the bolt locks to the rear and the first round drops, we're ready to rock. There were no sights on the gun. I always told my gunners "Use the force"........ and then "Walk the tracers onto the target"....... Every fifth round was an AP(I), the balance being HE. A surprisingly effective weapon at a time when a gap in capabilities became apparent (this was when the specter of terrorist small-boat attacks became manifest). I believe it was superseded in naval service by suitably modified versions of the 25mm Bushmaster. No doubt a more capable weapon....................................
