In this episode we cover the P-47 weapons, The 50 caliber machine guns, bombs, rockets, and more. There are comparisons with other air to air weapons, and we get into gun convergence and more.
Cannons vs. Machine guns, Fuselage vs. Wing Mounted, it's all covered in this video.
Notes: I made a comment about "average" soldiers, airmen, and sailors and said that they are the ones who win the war. I feel that needs further explanation. We all know that there were top fighter pilots, tank crews and so on who performed incredibly, and they certainly made a difference. However from the point of view of an equipment designer, whether is be a fighter plane, a rifle, or a tank, it has to perform well in the hands of an average soldier or it likely won't be a war winning weapon.

The propeller on a plane is there to cool the pilot. Don't believe me? Watch the pilot start sweating if it quits blowing! Glad to see you are going to do a video on the propeller Greg. This is a much needed part of flight that not much is out there to absorb in less than rocket science explaining terms.

Thanks for another installment in your great P-47 series. One factor which I didn't hear you mention in your comparison of .50 vs 20mm is that you can carry a lot more .50 rounds than 20mm rounds in a given space. Thus an additional advantage of .50s is that you can stay in the fight longer.

I was a P-47 fan because William Wyler made that movie 'Thunderbolt'. The squadron commander of the featured unit was Lt. Colonel Gil Wymond of Louisville, Kentucky. He flew over almost 150 misssions in a P-47 during the war but was killed flying a Republic F-84 in 1949. This is why Gregg's videos are so important. Great men die in bad airplanes.

I have never heard an American ww2 pilot complain about only having 50 caliber guns on their aircraft. As a matter of fact they seemed quite happy with them and from what I can tell by looking at gun camera footage seemed to be very effective weather against other aircraft or ground targets and they seemed very reliable.

I saw a documentary on the P-38 Lightning and some of the pilots remarked how that single 20mm canon in the nose would just "tear up" any plane in front of it. Yes, it had 4 .50 calibers as well, but with roughly 1 of every 6 rounds coming out as a 20mm shell the pilots were very impressed with its performance. Especially when you consider how lightly most of the Japanese planes were built.

The Navy has always preferred in-air charging of gun due to the crowded nature or the Hanger/Flight Deck. Far, FAR too many squishy vulnerable things(Deck Crew, Pilots & Other FULLY Loaded Aircraft) both below decks & on the Flight Deck to have live guns/ordnance on the aircraft. That's one of the reasons the Electronic Arming systems were installed on the SBD Dive Bombers at Midway, some of which malfunctioned, creating early releases. The Navy has always been a little leary of live ordnance on a Rolling & pitching Flight Deck/Hanger that is as much of "Organized Chaos" as a carrier spotting a strike package, nothing quite like a plane waiting in the Stack to launch that accidentally ventilates with guns another aircraft overloaded with ordinance & fuel or releases bombs/rockets into the plane park before launch.
@otohikoamv
@otohikoamv 3 года назад
Always amazes me how often these lessons seem to be repeated - crowded situations and weapon systems that can arm too early do not mix, on board a ship or otherwise. One lesser-known landlubber instance of this would be in Vientiane, Laos in early 1964 - when an (American-provided) T-28 being serviced on the ramp had a .50 cal gun pod go off into another T-28 that was already armed with a pair of 500lb bombs. Net result = quite literally half of the Laotian air force's combat strength (a dozen T-28s, plus a couple of Air America aircraft and a Russian-made helicopter) were destroyed by a chain reaction within minutes, at a crucial time in the Southeast Asia conflict (not long before the Gulf of Tonkin resolution). It pales in comparison to some of the carrier fires (including those during the Vietnam era) by sheer scale, but it had some very serious knock-on effects for the broader conflict.

So I no zero about guns and little about planes, but does "charging" mean having a bullet in the gun itself ready to fire? And you're saying that for safety reasons, the Navy didn't want to have bullets where being jarred could somehow set them off, but instead have the gun barrels empty until the plane was actually going into combat, and therefore they needed a charging system to do that initial load while flying? And that this charging system gave the added ability to clear jams but that wasn't the main reason to have it?
@GregsAirplanesandAutomobiles
@GregsAirplanesandAutomobiles 3 года назад

My friend wally groce flew one in ww2 . when it first came out he said everyone was afraid to fly it. he said it did not fly well at all at low speeds, but when you held it open it was his favorite plane. he shot down a ME 262 . did you know it had cameras ? he has a photo of the shot that took it down. he said his wingman strafed a long train with the 8-50's he said the power was so much it slowed the plane down , and knocked the train over. just the force of 8 -50's did that. wally died a few years ago, he was a fine man all the way. you can google him.

My uncle flew Spitfires in North Africa and Italy. There was not a lot of aerial fighting in Italy so they were mainly doing ground attack. He said he would have rather had his old training Harvard for ground attack than the Spitfire as there was a great big engine in front of you in the Harvard. This was a big surprise to me as a boy that someone would take an AT 6 over a Spitfire but then he was the one in the firing line. That was a revaluation to a kid who idealized Spitfires and Mustangs. Two rows of radial engine pistons make for a lot of protection but more importantly the insight of a pilot goes to why confidence is so important in the cauldron of reality. Thunderbolt pilots were confident because they had a lot to be confident about and a plane they could trust.

​@@dennismason3740 There are good arguments for both cannon and higher calibre MG's like the .50 cal... not rifle calibre though, they were all but useless! It really did not take long for us Brits to move towards cannons after the Battle of Britain. True, cannons have more punch, but 20mm cannon rounds are pretty damned big and heavy, so while an 8 gun P-47 could take up to 500 rounds per gun, a four Cannon C Wing late war Spitfire could take maybe 80 rounds per cannon. I believe the Tempests and Typhoons could carry a few more... but you get the point.... I think the Brits went for more punch, and the Americans went for more dakka with enough punch to matter! Both approaches were perfectly fine... but both approaches had strengths and weaknesses. The amount of ammo available to the guns was a definate weakness of the 20mm even if the Hispano had strengths elsewhere.....

Another great presentation, thanks! One thing of note, the Hispano-Suiza gun was Spanish mostly in the name. The French arm of the company was a separate entity and after the outbreak of Spanish Civil War became completely independent (and soon also nationalized by the French goverment). The chief designer and co-founder of the company, responsible among other things for the gun project, was a Swiss gentelman named Marc Birkigt. So it was more like "Swiss design, made in France".

Since my last post, I found a small bit of USAF weapons history that you might find interesting? In Korea, the Average range of effective fire, IE the target gets shot down, was 750 Yards with the six fifties that most of our planes carried. We shot down a lot of MiG-15s! The Brits used four 20s in their jets, but were much less effective if you divide kills by missions. After much study, the USAF found that RoF, MV and BC were much more important that weight of fire! We reduced the weight of our 20 MM shell buy 28%, increased MV to 1,036 M/S, made it much more pointed and increased the rate of fire to ~6,000 rounds per minute! Either four M-39 revolver guns at 1,500 rounds per minute, per gun in the F-86H tested in Korea to good effect. Or the six barreled Vulcan gun. In every case, they found the more pointed shell at much higher M/V and at higher rates of fire was very much more effective than the much larger and more powerful Russian guns in the MiGs! This was born out to the Present day in encounters in the middle east between older MiGs and our newer jets! They miss more and while the individual damage might be worse, it was not enough to knock the plane down. But flying threw the Vulcan gun's bullet hose killed everything! For the F-22, they went so far as to test reducing the weight of the shell to 84 grams and lengthen the barrel to increase the MV to 1,525 M/S! Only logistical reasons why they did not adopt this.

@@martijn9568 are you forgetting the Finnish Brewster? Interesting story: desperately short of airplanes the In April 1939, the Finnish government contacted the Roosevelt administration, requesting the supply of modern combat aircraft as quickly as possible. On 17 October, the Finnish Embassy in Washington, D.C., received a telegram clearing the purchase of fighter aircraft. The only strict requirements laid down by Finnish authorities were that the aircraft be already operational and able to use 87-octane fuel Part of an F2A-1 shipment - 44 aircraft originally intended for the US Navy - was diverted to Finland, by the US State Department, after the USN agreed to instead accept a later shipment of F2A-2 variants.On 16 December, the Finnish government signed a contract to purchase 44 aircraft: a F2A-1 variant designated Model B-239E by Brewster. Unlike other fighters already in service, the F2A-1 or more precisely B-239E lacked self-sealing fuel tanks and cockpit armor. However, the B-239E was built with a more powerful engine than the F2A-1, in the form of the Wright R-1820-G5, producing 950 hp and the capacity to carry four machine guns (instead of two carried by the F2A-1). The B-239E was also "de-navalized" before shipment: equipment such as tail hooks and life raft containers were removed. The upgraded engine and reduced net weight like omitted armor and de-navalization resulted in an improved power-to-weight ratio and better general performance. In four batches of the B-239E was shipped initially to Norway in January and February 1940. The crated fighters were then sent by railway to Sweden and assembled by SAAB at Trollhättan. After delivery of the B-239E, the Finnish Air Force added armored backrests, metric flight instruments, the Väisälä T.h.m.40 gunsight, and four .50 in (12.7 mm) machine guns. The top speed of the Finnish B-239s, as modified, was 297 mph (478 km/h) at 15,675 ft (4,750 m), and their loaded weight was 5,820 lb (2,640 kg. In short it was a different airplane and in hands of great pilots in service from 1941 to 1945, the fighter Squadron 24 claimed 477 Russian airplanes with the combat loss of just 19 Buffalos, an outstanding victory ratio of 26:1. It is is worth to note that B-239 was popular among the Finnish pilots and mechanics and gave various nicknames but it was not called "peanut special"....

The end result of this testing was to give the pilot a rear view mirror so he could adjust altitude if he was making a contrail.

Fantastic series Greg! If I may offer my 2cents in regards to a significant reason why a majority of US aircraft during the war were armed with M2 series MGs. Logistics. Simple and not very sexy. However even nowadays, procurement costs, shipping ease of storage for .50 ammo plays a role in planning what you’re using. You’re points are valid and I do believe true. But I’d be will to bet at the end of the day it’s a bean counter pushing to the decision point to use like items across the board in when you dive down the rabbit hole of the overall concept of support.

Excellent as usual, Greg. I suspect part of the reason for the role reversal (ground attack vs. high altitude) for the P-47 had to do with battle-damage strength of the R-2800 compared to the Merlin. My Dad's F6F-5 (Same engine as the P-47) took a Japanese 40mm hit to the engine, another to the wing root (I have photos), and flew him 250 miles back to the carrier, where he landed without incident. The plane was pushed over the side afterward as "unrepairable." On another mission, his F6F took a 20mm round to the prop hub, lost about 85% of its engine oil over the course of the 200+ mile flight back to the carrier, but still had enough to get him aboard. Engine was changed, the plane went back into service. I've seen that photo of a P-47 firing at night (at about 28.00) in a couple other places, and always admired it, and also wondered how they got the shot. I'm still not clear on what distinguishes a "cannon" from a "machine gun" as an aircraft weapon. Is it whether or not the round fired has an explosive charge? As for convergence, and charts notwithstanding, I'm going to argue that the M2 Browning was not a match rifle. Unless there was zero wind and no deflection in the shot (possibly common - I have no idea), a .50 caliber round flying through a 250-300 mph wind at an angle (even at 2,500 fps) seems likely to depart from its intended course fairly often. Probably why some pilots were "good shots," because they knew how to make allowances for that on the fly, while others never acquired that skill. The Brownings did jam occasionally. My Dad shot down a pair of Tojos over the Philippines during the Leyte Gulf engagement, one of them when his "…wingman's guns jammed, so I polished it off for him." And, since I'm talking about October, 1944, Dad's Hellcat carried a 500-lb semi-armor-piercing bomb on another Leyte Gulf mission, which he put through the flight deck of a Japanese carrier in Ozawa's "bait force" off Cape Engaño.

The P-47 Thunderbolt is my all time favorite fighter of WW2. What a great aircraft, an air killer. The P-38 Lightning was an excellent shooter with all its guns focused straight in front off the nose, but it had problems at altitude in Europe. The "Jug" had some serious safety armor around the pilot's tub. What a monster with twin radial "wasp" engines.

In William Bartsch's book "Doomed at the Start", about the 24th Pursuit Group in the Philippines at the beginning of World War 2, he said that the P-40Es sent there had hydraulic gun chargers, but the depot ordered that they be de-activated because they had a tendency for the hoses to break. This was a big deal because the same hydraulic system also operated the landing gear and flaps. Whether they ever rectified this problem I don't know.

@ditzydoo4378 3 года назад
This was an outstanding video. I love the fact you went into the reasoning behind .50 vs 20mm in the US fighters of the time. The HS.404 is an autocannon originally designed and produced by Spanish/French company Hispano-Suiza in the mid-1930s. The P-38 had one from the start but would have been better served with Six-50's in the nose. You would eliminate the fall of shot difference between types. And the P-38 had no convergence since all guns fired directly ahead giving the pilot a kill area from the muzzle, out to the limit of the projectiles flight path. The standard weight of a .50 caliber is 650/750 grains per projectile.
@spindash64
@spindash64 3 года назад
That’s a fair argument, but I’d argue that the difference in ballistics between a Hispano Mk II and a Browning .50 cal were small enough that it was worth having the additional High Explosive capability, which meant that a burst anywhere on the target aircraft had a good chance to do severe damage, while just .50s would need to land a burst on something more direct, like the engine block, a radiator, or one of the fuel/oil/hydraulic lines. On the flip side, HEFI ammunition is less effective at dealing with armor plates and engine blocks, so having the 4 .50 cals “escort” the HEFI rounds into a burst helped cover the weaknesses of both weapons.

I've often wondered if the explosive bolts in the prop hubs were timed to avoid throwing blades through the fuselage, especially for the sake of the poor radio operator. Being in an Airacuda in combat would be bad enough. Being in an Airacuda that was going down would be worse still. Knowing that at any moment you might have to share your work station with a prop blade traveling at several hundred miles an hour had to be the pits.

Thanks for the very high quality presentations. There was a certain flight simulator that introduced the m2 Browning with the introduction of US planes....initially, the weapons modeled were powerful but showed tremendous dispersion. The community really put the heat on the developer to change this...eventually he did and when he did, the guns were also reduced in effectiveness (power). This video would have been wonderful to have at that time because the developer probably had it closer to correct with his first iteration.

Nothing about them, barrels, triggers, or was anywhere near the quality needed for sniping. More damning: they would destroy the fragile scopes of the era. Limiting them to iron sights limited them to the same range as the normal sniper rifles.
