Just a bit of trivia but the “pounder” cannon sizes used by the British is a holdover from the old days of muzzle loaded cannon. The size of the cannon referred to the weight of the shot fired from it. So a 2 Pounder fires a shell that weighs 2 pounds for example. They only stopped this naming convention completely after WWII.

Roger Hill, captain of the Hunt Class destroyer Ledbury had an interesting Pom-Pom crew. He frequently complained to his ‘Guns’ officer about their wearing of football shirts and cloth caps during Operation Pedestal. He also described them as being “a blood thirsty bunch”. On one occasion during Pedestal in order to raise moral amongst a very tired crew Hill deliberately held fire on a pair of attacking SM79s until well within his close range guns (ie he didn’t fire his min armaments in AA configuration) range. He then ordered ‘Open fire’ and both the torpedo bombers were shot down. As one of the SM79 crews clabbered out of their downed and sinking kite the Pom-Pom crew asked for permission to open fire on them! Hill bellowed Convention chapter and verse at them, stating “you may not fire on a defeated enemy, you blood thirsty bastards!” (From Destroyer Captain, Roger Hill).

@@rob5944 I picked the word "awesome" rather than cool because of how it looked and how it worked rather than how it was effective. Damn right the bofors worked better but no shit we all know that.

[@xxnightdriverxx9576]

​​@@rob5944 the most important thing is that the 40mm Pom Pom was available in large numbers when the war started. The 40mm Bofors, in the mass produced quad mount we mostly think about, did not exist until mid 1942, and did not saw widespread usage in the US Navy until late 42/early 43. By the time the British Royal Navys losses to aircraft were at their height, the 40mm Bofors was not yet available. It is better to have a good enough AA gun for the entire war than to have the best gun for only half the war. And the British were deploying the Pom Poms in numbers of up to 48 barrels per ship in 1939, at a time where the US was designing the Iowa's to have only 16 28mm barrels. Yes the 40mm Bofors existed as a gun from the mid 30s onwards, but those were single land based mounts, which were not suited to mass production. They were designed specifically to require a lot of handwork with "file and drill unti it fits" style instructions, because the Swedish government was trying to give their citizens jobs in the wake of the 1930s economic crisis, so taking as long as possible for a single gun was actually the goal of the designers at that point, otherwise there would be even more unemployment. For this reason the 40mm Bofors saw only limited service before 1942.

[@williamzk9083]

The magic was actually in the Remote Power Control of the guns. The Royal Navy used a computer called the HACS high angle control system to calculate the firing solution which itself could use type 285 radar for the range. The system progressively improved with GRUB Gyro Rate Unit Boxes. -The Japanese, German and US Navy had nothing like it in 1940. Way ahead. -Had the Prince of Wales had functioning radar (3 of the 4 were down) and Boffors 40mm instead of POM POM 40mm she would never have been sunk.

[@harveywallbanger3123]

Mass of fire = pre-radar thinking. Back when your best bet was literally aerial suppressive fire in the hope it would distract the enemy enough to miss you. By the end of the war, proxy fuses and shipboard radar improvements meant the same 40mm Bofors shot down far more enemy (and did it far faster) than in the beginning of the war.

Interesting Fact: Japan and Italy used and produced their own versions of the 2 pounder pom pom up until WW2, when it was succeeded by newer Anti-aircraft guns. Also, Vickers exported a Mark E 6-ton tank model using a 2 pounder pom pom as a self propelled gun carrier; with Thailand being the only customer of that particular model.

In the 1961 movie "Sink The Bismarck", the octuple pop-pom is often shown as the Germans' AA defense. Funny enough, if the Germans had a rapid-fire close AAA weapon like that they MIGHT have had a chance to fend off the air attack that doomed them.

[@alexandarvoncarsteinzarovi3723]

That was the quad barrel 2 cm Flak 30, Flak 38 and Flakvierling 38, chambered into the 2,0cm (.78 in) to fire the 20×138mmB or Long Solothurn, not a bad gun really especially in its quad system, but the gunners were all green,

[@fernandomarques5166]

Specially considering how Bismarck's AA suite was mostly comprised of 20mm guns in single mounts and the utterly useless 37mm breach loading dual gun mounts.

[@richardbell7678]

The Bismarck was actually doomed by a cost cutting measure that made perfect sense, at the time. The assumption was that the Bismarck would only need to engage aircraft that were attacking itself, so it would never be engaging crossing targets, let alone receding targets. Compounding the issue was forgetting to account for possible wind condition when selecting the calibrated speed range of the fire control predictor. With the Bismarck heading full speed, into gale force winds, instead of being sitting ducks for the 10.5cm, radar directed heavy AA battery, the swordfish were closing at too slow a speed to be within the calibrated speed range, so the predictor could not supply the correct setting for the variable timed fuses. If the predictor was designed for area defense, the predictor would have been more expensive, but the calibrated speed range would have included high performance aircraft flying at the ship, high performance aircraft flying away from the ship, and all speeds, including zero, between those extremes, which would have doomed the incoming swordfish.

[@ThommyofThenn]

There's something about the chunky look and almost ponderous rate of fire of this weapon that has a bit of "charm." If such a label could be applied to a deadly weapon.

[@442dudeathefront]

One of the reasons Prince of Wales and Repulse got sunk was that the Japanese aircraft didn’t know they where actually under heavy AA fire and largely felt safer and where able to execute their attack runs under less stress thus more accurately all because the Pom Poms lacked tracer rounds. It’s largely only after the Japanese planes returned home did they realize they’d been shot at a lot.

[@Luis-be9mi]

That and that Prince of Wales and Repulse were sent out without any air over. Further proving the importance of air power.

[@bofoenss8393]

@@Luis-be9mi Post war analysis has shown that had the ships had the tracer rounds, there is a good chance they would have survived. There were 85 bombers attacking them. 4 were shot down and 28 were damaged, many severely. That's over 40% of the attacking force. In other operations, Japanese bombers in similar attacks veered off against lesser AA opposition. As mentioned, the effect on moral and stress seeing tracers converging on you while doing a bomb/torpedo run lessens you focus significantly.

[@xxnightdriverxx9576]

​​​​@@Luis-be9mi it's more complicated than that. The British intelligence and admiral in charge were well aware of the bomber thread. They knew a routh number estimate, they knew their airfield location, and they knew their range. The British admiral was actively choosing a course and position that would have kept him out of the bombers range, thus no air cover would actually be required as the japanese planes would not be able to reach them (and no carriers were close), and the British planes were required to support the land battles which was underway at the same time. The planes had the choice of attacking japanese land forces to help the British troops who were losing and needed all the help they could get, or they could fly over a few ships which could not be attacked by the enemy's planes because they were out of range. Which one is more useful? The problem was that just one or two days before the British force sailed, the bomber squadrons got switched out. The new models there were the G4M Betty and G3M Nell bombers, which had longer ranges than the ones stationed there previously. Now the British ships were in range. But the British admiral and intelligence didn't know that. Not providing air cover for these ships might be seen as a mistake when looking at it now with hindsight from an armchair historian position; but at the time from the British view the decision was actually the right one. The planes were needed elsewhere and the British ships should not have been in range of the japanese aircraft, and they were specifically sailing a course not to get into range. It was just bad luck for the British, but from their perspective they did everything right. Except bringing tracer rounds. Had they known that the bomber squadrons had been switched out so they now had longer range, there certainly would have been air cover provided, or the ships would not have sailed so far north. Everything they did was under the assumption that the japanese bombers could not reach them, which was also true 2 or 3 days earlier

[@Birdy890]

Daamn, that's actually extremely interesting and good info. Thanks for sharing.

[@astratan2238]

In addition to all that, they were actually scheduled to sail with a carrier, but the latter got in an accident just before they were timed to set off so they sailed without it.

[@fernandomarques5166]

Fun fact: the pom-pom, specially in its quadruple and octuple mounts, was considered one of the best anti-aircraft guns used against the kamikaze due to the sheer volume of fire and thus stopping power it had. Experiences with the pom-poms in the Pacific would heavily influence the Royal Navy into developing the Sextuple Bofors mounts installed aboard HMS Vanguard.

[@moblinmajorgeneral]

Quad mounted Bofors were devastating enough, but six?

"One of the Best" not really. The Boffors quad had twice the range of the 40mm pom pom and more than twice the rate of fire of the octouple POM POM. It was all Britain could afford

If the pom poms were firing then the enemy were getting dangerous close. My father was a Marine aviator on the USS Block Island (2) , the first Block Island was sunk by a German submarine, the only carrier lost in the Atlantic. During the battle of Okinawa the pilots were spread out in the carrier to prevent multiple pilot casualties as happened on another carrier. My father said that as the kamikazees got closer the long range guns started firing ,then the mid range and finally the pom poms which meant the Japanese were really close. All the meanwhile all they could do was to listen to the guns firing. He flew a TBM during that time, dropped a 1,000 lb. bomb on Naha castle on Okinawa, along with blowing up a lighthouse on Saipan, he said he wouldn’t have attacked the lighthouse but the Japanese started firing at him. And the fact he still had rockets left after a bombing run. He served during WW 2, the Korean War and taught fighter school during Vietnam , earned 2 distinguished flying crosses along with numerous medals over that time. Flew the Stearman (Submarine patrol in the Virgin Islands) Hellcat, TBM, Corsair, Panther and Sabre jet, and finished with A4 Skyhawks in the late 60s. In Korea he landed a TBM on the beach in North Korea to drop off 2 Army intelligence soldiers and picked up 2 to take back. But he said he flew more beer and bullets than bombs in his TBM during Korea. Another role in Korea was flying a Twin engine Beechcraft up and down Korea getting parts and mechanics to various air bases to fix up damaged planes. A most unassuming kid from Wyoming.

Glad you covered this Johnny QF 2-pounder naval gun outshine the QF 1-pounder pom-pom. Swedish Bofers were a great gun in ww2 but they only began production in 1934 17 years later then British QF 2-pounder Mark II entering service in 1917. Britain had a lot of equipment left over from ww1 so they found ways like strapping them together to get use out of them. The USA basically built it's military up from the ground & similar for Germany prior as a lot of ww1 Equipment the Germans had from ww1 was sold in their recession or decommissioned under treaty agreements & such.

Britain had anti air autocannons from 1903. USA only started production poorly in 1938 & due to the shortage of Autocannons did something no other power did mounting M2 browning's in place of autocannons for anti air protection which was not suited to anti air but nice for infantry support fire. The USA post ww2 realised the short comings of not having sufficient autocannons they hired ex Nazi's to develop the M39 revolver cannon in 1952 based on the German Mauser MG 213 which would be developed M61 Vulcan rotary Autocannon that the Germans envisioned but lacked the means & funds at the time to achieve it. Even the USA would take decade & 1/2 with naughty Germans! Most of NATO's Equipment is just ww2 German technology with new panels & a ne coat of paint on it. GM3 is just a MG42 sim lined.

Actually, a single Bofors was considered as effective as two pom-poms, not eight. So a quad Bofors, as used by the US Navy, would be equivalent to an eight-barreled Pom-Pom. Single Pom-Poms were used in large numbers on motor gun boats (MGBs), older destroyers, and many other vessels. Quad Pom-Poms were mounted on newer destroyers and cruisers, which in many cases retained them until well into the 1950s, even though there were plenty surplus Bofors available.

Jesus, that Nordfelt Flak 14...there ought to be a statue of limitations on how big something can be and still be belt-fed! And neat footage throughout!

I'm watching the way it rocks and thinking no way in hell they're hitting anything.

such a distinct and recognizable sound

Man, that 8 barrel Pom Pom gun is one mean looking weapon!

[@admdubya2107]

It lays down a pretty sick beat

[@richardglady3009]

Great video. Thank you. The comparison between the Pom Pom and the Bofors was very interesting.

[@johtajakansio]

Ears were much stronger back then

[@Chiller11]

I think the British seamen shooting Pom Pom guns wore short short skirts and finished their volleys by doing the splits.

[@leekaijit36]

Fun facts: If you play Warhammer 40K: Boltgun, When you firing the Heavy Bolter, the Bolter sound share similarities to the Pom-Pom Gun (but firing faster)

[@RayyMusik]

2:44 The Chicago Piano was the multi-barreled US 1.1“ gun IIRC.

[@JohnnyJohnsonEsq]

They shared the nickname oddly enough

[@jonathanstempleton7864]

Those WW1 Germans appeared to be stationed at the coast which made me think this is an almost forgotten little theatre of the war. What happened when the trenches met the sea or the Swiss border?

[@TheArklyte]

Now you need to remember that 40mm ie 2 pounder Pom Pom had automatic fuze setter for it designed in interwar period for use in dual purpose ie direct action and timed fuzes. Imagine if that feature was retained by the time of WWII and octuple mountings? Just need one command from radar and all fuzes are set to correct distance😂

[@Erika_Itsumi_GUP]

“Seaman” 😂 this is why we replaced that word with O.S., A.B 😂

[@scrubsrc4084]

The chicago piano was a 1.1 inch quad mount that was replaced by the bofors

[@eamonnclabby7067]

Excellent analysis ,thanks for this one,sir, well done...😊😊...E...

[@Stonewielder]

Not a lot of ear protection in those old clips. Ahh, the good ol' days!

[@DONALDSON51]

Great Stuff as ever. Was the clip with John Hall interview from armoured carriers channel?.if you haven't seen it I'd highly recommend the channel. Great mix of old footage and interviews.. That channel is criminally under subscribed

[@RandJ]

Another great video thanks .

[@Headcase0570]

00:47 Dude is standing next to the loudeners without hearing protection. Military grade tinnitus right there.

[@tarnishedknight9909]

Thanks for that pun to get my day started :)

[@bobmetcalfe9640]

You will notice the complete lack of ear protection there. My grandfather was in the artillery in World War I and his hearing was never the same afterwards. My father seemed to have escaped too much damage in spite of being the number two on an Oerlikon for some time. I think he was lucky he got a radar qualification eventually. A lot less noisy.

[@Art-is-craft]

A small bit of cotton wool may have made all the difference.

My Grandad crewed one a pom pom gun in WWII. Hms mazurka i think. Corvette. Massive respect to him and all the lads that served or are serving!

[@arunsharma-dx4yn]

Post war the Mk 6 40mm mount only had six barrels. These were fitted to HMS Vanguard with some being radar-directed.

[@Cherb123456]

Thank you!

The army v navy game is hardcore.

[@jaaqess2525]

“The Chicago piano” is a hilarious name considering the Thompson is “the Chicago typewriter”

[@merlemorrison482]

during vietnam, Bofors quad mounts were often called pom poms.

[@michaelandreipalon359]

Always with AA gun weaponry and their weirdly charming organ gun variations. Strange to not see any fictional media for this, by the way, even if they'll be similar looking blueprints from a Star Wars Legends sourcebook or whatever. And on a over the top literal standpoint, cheerleading pompoms are better off as secret emergency grenades, particularly the smoke kind.

[@BamBamBigelow.]

Pom-Pomming some shells up there 🤔

[@edgychico9311]

BF1 has this anti-air gun too.

[@Menuki]

“Your hearing loss is not service related”

[@Willchannel90]

The veterans and Navys know these.

[@ebt1992]

Just make the barrel a few inches shorter and the funnel 50 centimeter wider. Maybe it makes this farce more accurate.

[@Serviervorschlaghammer]

In France it wasn't called "Pounder Cannon", it was called: Royal with POM POM!

[@jamesbarca7229]

I never knew the US 1.1-inch anti-aircraft gun wasn't the only one nicknamed the Chicago piano.

[@HappiKarafuru]

Then suddenly Bofors - Allow me to introduce myself

[@mikeryan7468]

My friends father used these weapons in WW2. He said they jammed all the time, and were not thought very effective. In period film you can see some in effect jamming all the time.

[@xxnightdriverxx9576]

They were not very effective compared to the US 40mm Bofors gun, but compared to other medium WW2 era AA guns, the Pom Pom was still very good. It was better than the 20 and 37mm guns fielded by Germany and Italy, and we don't need to talk about Japans 25mm gun. Statistically, you need thousands of rounds to destroy a single incoming enemy aircraft, which is why gun crews often think their guns were not that effective. Even the 40mm Bofors needed on average more than 1700 rounds to shoot down a single plane (see US anti aircraft action report September 1945). I don't know numbers for the Pom Pom, but due to its lower velocity it is likely higher. But what often gets forgotten is the psychological effects on the attacking planes crew, when you know you are being targeted by such a gun, you are very likely to break off your attack, or drop your bomb/torpedo early (which makes it far easier for the ship to evade). However, those factors are not visible directly to the gun crew, and they are very hard to measure in numbers, but they make out most of the effectiveness of an AA gun. Even USN 40mm Bofors gunners often felt like their guns were not that effective.

[@matthorrocks6517]

I sure hope those guys had hearing protection.

[@georgeboesdorfer4046]

Keep up the good work and maybe do the kar98

[@calvins4940]

I've always thought the pom-poms were a little pompous myself. I'm sorry that one slipped out.

[@thenomadrhodes]

How did these guys stand so close to these with no hearing protection.

[@CFMLEAP]

My great grandad was a gunner for these guns on the HMS Renown throughout the entire war. He even spoke about having to fight off Kamikaze pilots at one point.

[@diegoferreiro9478]

I always thought the 'Chicago Piano' moniker was given to the American 1.1" quadruple mount instead.

[@stuew6]

Also Canadian Tribal-class Destroyers were Equip with a Single Quad 2-pdr before Wartime Modifications. To 40mm Bofors

[@billyponsonby]

I always wondered and now I know.
