I believe this is not a case of a tank gun on an aircraft, since the T13E1 / M5 75mm gun was developed specifically for installation in attack aircraft. A derived version known as the M6 75mm gun was later installed in the M24 light tank, so this is really a case of an aircraft gun on a tank.

@dougjb7848 Месяц назад

The first 75mm mounted in the B25G was a manually loaded 75 mm M4 cannon, originally developed for armored ground vehicles. The T13E1 was developed from the M4 to be mounted in the B25H, and then that was modified into the M6 version for the M24. So it was a case of a gun for a tank, which was developed into a variant for an aircraft, which was then developed into a gun for a tank.

According to Gen. Kenney's book, the "strafer" B-25s and A-20s did just fine against shipping once they perfected the skip bombing technique. Even a fairly light bomb (ie 100 lbs) is going to be more powerful than a 75mm shell (16 lbs). The idea was, suppress AA fire with a storm of .50 cal on a high speed run-in and skip a bomb into the side of the ship.

@mikepette4422 Месяц назад

exactly suppression of the returned fire from shipboard AA was the goal not to sink ships with the guns

@bilalsadiq1450 Месяц назад

That's surprisingly similar to the A-10 story in the Gulf war and later, where the use of the 30mm cannon for tank killing got sidelined due to the use of AGMs on the hardpoints. Kinda makes it redundant to use in the end if all the compromises to mount the cannon aren't even used (although it was still useful in COIN operations so it wasn't a complete loss).

@lookythat2 Месяц назад

@@bilalsadiq1450 To me one of the most underrated features of the A-10 was its wealth of hardpoints. Like the A-1 "Spad" it was intended to replace, it was intended to be able to carry just about everything -- and lots of it. The USAF was remembering the Spad -- the first concept for the A-X program was for a turboprop. If a peer conflict had broken out, the 30mm would've seen lots of action. There would've been lots of targets, 30mm is a lot cheaper than Hellfire missiles, and they'd have more than six shots (a normal Hellfire load).

My father-in-law flew straffer B-25's for the 500th squadron/345th bomb Group (Air Apaches) out of Papua/New Ginea in 1943. He only mentioned flying with the .50cal gun package but routinely carried 100 pound para-Fragmentation bombs and 500 # conventional bombs. There is a photo of his a/c coming off a skip bombing run in the book Warpath Across the Pacific that is the historical record of the 345th Bomb Group. According to Ed Allen the modified B-25 c and d models were very heavy on the controls and if the pilot lost either engine for any reason the a/c was committed to a forced landing....it could not maintain controlable airspeed on just one engine.

@immikeurnot Месяц назад

20mm vs .50 cal also comes down to reliability. The Hispanio Suiza cannon had feeding issues (the British ended up fixing this after the US decided to stick with the .50 cal), but the Browning M2 is kind of legendary for their reliability. The initial design was so good that they only in the last couple of years modified it, and that A1 modification was just to make barrel changes easier by eliminating the need to adjust headspace and timing.

@neiloflongbeck5705 Месяц назад

The Air Ministry selected the 20mm cannon over 0.5in machine gun in the mid-1930s, around the time they selected the Spitfire. They did this even though the 20mm was much less reliable than the 0.50in machine gun as it had more potential.

Yup. Rockets are just a better solution than a heavy large caliber gun. Easier to integrate onto many diff aircraft, just as much if not more explosive firepower, weigh much less, and the aircraft gains its performance back after expending them, rather than carrying around the empty cannon after firing all the ammo.

@lorenzcassidy3960 Месяц назад

@@cattledog901 I'd say definitely more explosive firepower than a single large caliber gun: the most common configurations on US fighters and fighter bombers of 6 or 8 127mm (5 inch) HVAR rockets are equivalent to a broadside by a destroyer when fired all at once.

@MrLBPug Месяц назад

Skip bombing as well. Using a 500lbs or 250lbs bomb that, well, _skips_ along the water surface onto a big merchant ship, causes far more damage than a 75mm shell. It wasn't a bad idea per se to try and use a big cannon, it's just that other methods were more effective.

@patrickwentz8413 Месяц назад

So the real punch from the A 20, B 26, B 25 came from either skip bombing or parachute borne fragmentation bombs when operating low level. A 75 could have been useful a year earlier going after light shipping or when attacking an airfield point target.

AktUalLY... The T13E1 75mm was developed as a lightweight gun for the B-25H to be able to fire the French 75mm round. It was the US's common artillery shell. It was only somewhat related to the M4's gun. I think just the breechblock. It was then applied to the M-24 light tank. So it was an aircraft gun that became a tank gun.

"Why put a tank gun on an airplane?", to keep the A-10 in service obviously. But are you actually hinting, nay even suggesting that the solution is to arm the venerable Warthog with a six-barrel, 75mm / 70??? You're mad, man! Utterly mad! The added weight and recoil! We'll need more engines and a lot more wing area. It will have to be a biplane. It's brilliant. Where's my slide rule. There will be dozens of calculations to make this work...

@angrybirder9983 Месяц назад

The "big gun on a plane" concept has largely outlived its usefulness. Completely removing the gun from the A-10 would save a good amount of weight, but also mess with the center of gravity so much that it would tip over. A 70mm would be completely insane, since (guided) 70mm rockets (APKWS) can do the same job much better.

My dad was a B-17 pilot in WWII. Among hi old photos was picture of a B-25 with 4 fifties and 4 40mm Bofers in the nose. Dad said it worked well for ships and tanks, but you had to watch how many rounds you fired because the recoil of the Bofers slowed the plane down and if you kept firing you could stall the plane. Dad always said the B-25 in the right hands flew more like a fighter than a bomber. He said it's maneuverability, agility and tight turning radius made it the perfect plane for a lot of mission besides bombing.

IIRC, there was a plan to mount a 37mm on the A-26, but it seems only the bomber nose and .50 cal gunship noses were used in the field. It seems that both the A-26 and the B-25 could mount an astounding amount of forward-firing .50 cals, with upwards of 20 that could theoretically be carried, with additional wing mounting and gun pods. I think in practice, only the glazed nose variants of both aircraft used wing-mounted guns. Would love to see pictures that prove me wrong😊

The American mentality is that "there is a space there, it can fit, or we can make it fit, therefore we can put a gun there; we will put a gun there." We followed the same mentality on our ships, too. Where the to the point that whenever we refitted or made a new fleet carrier we put more Bofors or 20mm Oerlikons on it. To the point that we were actually running of spaces to put them. America actually played Tetris with how to fit more guns on its aircraft and ships.

I will throw one caveat out about this- remember, for a large part of the war the Southwest Asia operations were largely considered low priority, so they rarely got the equipment and support needed- so they had to make do and improvise with whatever they could beg ,borrow or steal (and salvage from wrecks) In fact, quite a few of the "field modifications" of the aircraft flown by the 5th Air Force were the result of 2 men in particular , General George Kenney and Major Paul "Pappy" Gunn. In fact, when Kenney took over in Sept of 42, he did a inspection tour of his units. When he came to Gunns unit, he found him in coveralls on the flight line modifying a A-20 to add extra 50 cals scavenged from crashed P-40's to the nose of the aircraft. Quite a few of their ideas worked out, such as the strafing version of the A-20's & B-25's, the skip bombing techniques, the parachute bombs, etc. The 75 mm gun version obviously was a bit of a mixed bag

I think that if the B-25G had been available in time for the fights in the Marianas, and Guadalcanal, it would have bee a real show stopper. Unfortunately a good idea for '42, and '43, makes for a poor idea in '44, and '45.

No mention of Pappy Gunn, the man that was most responsible for adding the extra guns and later putting the cannon in the nose . He did the initial install and then worked with the engineers to improve structure. He was also the first one to sink a Japanese destroyer with the gun. It took quite a few passes though. Although he wasn't supposed to be flying any missions per General Kenny. Also not mentioned was that the bombs usually didn't penetrate the hull. After losing an aircraft that was following to close to the lead when the bomb went off they started using delay fuses. When the bombs went off under the ship the hull cracked and usually sank the ship. The tactic they used was to have one aircraft strafe the ship lengthwise and then the other come in to the side and skip the bombs into it. Read the book the Saga of Pappy Gunn Gen Kennys Reports(down loadable ). I first read about Pappy Gunn in Readers Digest in grade school. When my mother saw the name she told me that he used to come into a cafe she worked at in Charters Towers, QLD, Australia where I was born. That was the first forward operating air base for the USAAF in 1942.

There's a book called Whip, by Martin Caidin, about B-25s in the New Guinea theater. It is a novel; IIRC "Pappy" Gunn is in it, but the protagonist is fictitious. There's a line at the end of the book that I thought so perfect, and obviously always remembered. They are talking about how the success of the field-mod strafers has resulted in making them at the factory. Someone states, "They're even making one with a 75mm cannon." The response is "I'll buy a war bond if I don't have to fly it..."

Thank you Chris for including the Devil Dog. That is the displayed USMC B25 owned by the CAF based in Georgetown, TX. I wish I knew that you were in the area as I am a crew chief on her. This one has an interesting history as it started as a glass-nosed USAAF WWII bomber and was heading into the Pacific for the invasion of Japan. After the A-Bomb she was halted en route and retirned to the States After a few years of storage, she was then used by the new USAF as an advanced trainer for pilots going into heavies at Reese AFB in Lubbock, TX. Surplused in the 1960s she was sold to private operators ending up flying explosives for mining operations in South America. The last owner had her restored and configured to commemorate one of his WWII friends who was lost on his last mission in the Pacific while flying the PBJ-1. The CAF acquired her afterward and is now based on Georgetown, TX. Good job on this concept story Chris.

I had the fortunate experience to be inside a B25 at an airshow in my home town. It was the star of the show and for 500 dollars you could go for a short ride after signing a waver. I settled for the inside tour. Was an amazing experience.

I had an American cousin who loaded and fired the 75 mil on the B25H. He told me back in the late 70's that by the time they got the B25H there was really nothing Japanese to shoot up.

Here's a surprising fact about the 75mm gun on the B-25 - that gun became the main gun of the M24 Chaffee light tank which was a design of... Cadillac.

It’s crazy to see a 75mm cannon added to the B-25 to must it against the Japanese ships and ground targets.

Was there any evidence of using the 75 mm on non-shipping related targets? I would imagine against trains or even hardened ground positions, it would be a useful weapon to field.

Even as far as games go, playing simulator battles with a plane equipped with a large caliber weapon in war thunder proves to me that without thick AA cover, these tank guns are far more deadly to armor or emplacements than bombs that could just get replaced by tank gun HE.

@theodoremccoll3267 Месяц назад

My neighbor was a Marine Corps pilot on a B-25, on 6 August 1945 he attacked Rabul. He said they liked the 75mm hitting force but the recoil slowed the plane down too much. He said they would only fire once during an attack. His target priorities were ships, planes, boats and finally anything that they could find. Which was often soldiers farming. On the 16th he was on his way back to Rabal. The crew was told the war was over by radio, so they, dropped everything in the ocean, bombs, .50, and 75

The Mosquito had only the pilot. No room in the cockpit for a second seat and controls

@PiGood Месяц назад

I remember a B25 pilot giving a talk at our school once. He said theoretically you could fire 7-10 rounds before the plane would stall due to the loss of air speed. However in practice, they could typically only manage 3-5 shots. Apparently the smoke from the cannon would get funneled in to the plane and make it's way in to the cockpit. After 3-5 rounds you would often no longer be able to see out the windshield.

Some years back, I got a chance to examine one engine block and the T13E1 cannon of General Orde Wingate's B25H (43-4242) which crashed near Thuilon Village, Tamenlong District, Manipur, India. The Assam Rifles had salvaged some of it and they now are on display at the Assam Rifles Museum, Laitkor, Shillong. The aircraft belonged to the 1st Air Commando Group, I believe.

My uncle, Sidney Ballard, told me about B-25's with cannon that he maintained during WWII in New Guinea. He had been an enlisted man in the US Navy and left the navy to become an engineer, managing the logistics of various civil engineering projects. Sid worked for Aviation Enterprises managing maintenance when it started in 1940 in Houston, Texas. Shortly after the start of WWII, he joined the USAAF and was eventually sent to New Guinea to manage aircraft maintenance at an air-base there. I don't know which air-base, but it had hangars (he told a story involving Japanese prisoner labor, a fighter pilot who hated Japanese, and a hanger that was shot up until the figher's guns jammed). He told me that he had ridden in a B-25 with the 75mm gun for a mission which was successful. I don't know whether that was anti-shipping or ground attack. He and the crew thought the gun was not very effective. The aircraft were equipped with racks for rockets on the wings which were, according to Sid, more effective weapons.

@goetzliedtke Месяц назад

The reason I know of the rockets is because Sid was educating me on practicality and safety. Apparently, the rockets were loaded on racks which also ignited them with electricity (kind of like an Estes Rocket Engine). The pilot had a switch in the cockpit to ignite the rockets (I don't know if they all went of at once or not). The rack had a hook and a socket with the electric connection - loading involved hooking the rocket's front on the hook and plugging the rocket into the socket. This may have been a field mod since the incident occurred because the switch had been connected reversed. The loader checked the cockpit and made sure the switch was in the off position. He then hooked the rocket on the rack and, when he plugged it into the socket, the rocket ignited and the blast killed him.

What might be an interesting for a future video would be something on the B-24 variants that conducted low-level nighttime anti-shipping operations along the coast of China. Operating from central Chinese bases, those mounted radar and operated against convoys between Southeast Asia and Japan all the way into 1945.

Everyone should read the book Indestructable by John R. Bruning for the complete story of Major(not Maj. Gen as the picture said)Paul Irvin "Pappy" Gunn. Him and Jack Fox of North American Aviation created the Gunship idea in Australia. But not in a B-25 but first in the Douglas A-20 Havoc(Boston to you Brits). He's an unknown and forgotten legend of WWII and his story will blow your minds.

In naval combat, I always see destroyers getting up close and personal with large ships, sometimes down to a few hundred meters. However I never hear about the 50cals, 20mm, or 40mm aa guns being used on enemy shipping. I know it wouldn't pen like side armor, but even just a few shells from a 40mm would destroy anything on the deck or citadel.

@aldenconsolver3428 Месяц назад

You are as usual pretty much on the spot with that analysis. I have seen quite a few gun camera captured strafing runs and the multiple 50's chewed up the japanese air bases just about as well as would be needed. I would think that if the japanese had fielded more and better armour then the tank gun bomber would have had targets that the 50 cals would have had trouble dealing with and the 75 could have destroyed relatively easily. The ability of the plane could have had some value on the interior waterways in Japan shooting up the local transportation system but thankfully we never had to fight over japan supporting troops. The tank gun bomber was a fine plane, its just that the enemy failed to supply the correct targets.

It surprised me that Doolittle advocated removing the Copilot position. I wonder if he was influenced by the Mosquito design which also has no copilot position.

There's a photo sequence of a 75mm-equipped B-25 -- or so the captions claimed -- attacking a fuel storage silo. It worked. But now you mentioned it -- this one plane could have taken out most silos in one pass simply by using conventional bombs.

A family friend, John Fitch, participated in the flight testing of this weapon off the east coast of the US. He later moved on to the 4th Fighter Group flying P-51s against Germany. He survived the war, was a notable auto racer and invented the yellow sand-filled highway barrel, the “Fitch Barrier”.
