The intent of this video is to discuss the devastating effect the German Mg-151 20mm autocannons had on US Bombers in WWII. The Germans adopted Mg151 20mm autocannons firing the high explosive mine rounds. It took 20 to 25 strikes of this projectile to destroy a heavy bomber. Annotated combat footage showing the destructive power of the 20mm high explosive mine projectile is shown at the end of the video. Video features the BF109, FW190, P47, B17 and B24 airframes.

When we lived in Germany, I made it a point to get to know some elderly Germans who fought in WWII. One was a fighter pilot; night fighters and then transitioned to Reichsvertidigung day fighters. He had over 20 verified 4 engine bomber kills, and said he always tried to hit and engine if he could because it might give the crew more time to bail out. After the 2/13/1945 bombing of Dresden, he said he started going for the wing roots so the crew would likely be trapped by a collapsed wing. He said after Dresden, he wanted to kill as many British and American air crew as possible. Those who were able to bail out were frequently killed by civilians if the military authorities were not quick enough to rescue them.

​@@fawnlliebowitz1772an utterly asinine comment. It doesn't matter who started the war, targeting civilians (including women, elderly, children) is not only a war crime, it's subhuman unethical behavior. Countless children suffered tremendously painful deaths and unrecoverable injuries as a result of the firebombs. It is only reasonable for a pilot to want to avenge this even if that pilot himself is guilty of many immoral acts, fighting for Nazi Germany ranking at the top of that list.

What a great, well researched presentation. I was an Air Force weapons mechanic serving in Germany from 1961 to 1964. I was highly impressed with the simplicity, reliability and hitting power of the M-39 20mm cannons on the F-100 aircraft. That revolver cannon was reportedly developed from a WWII Mauser design. When the F-100 was replaced by the F-105, which was equipped with the M61, we found the Gatling-style gun and particularly its new, linkless feed system to be very unreliable and incredibly maintenance intensive. Even an attempt to load fresh ammo frequently resulted in the need for major maintenance on the system. Obviously the problems with the Gatling were worked out in subsequent years, but in my opinion the F-100 was a real gunfighter and the F-105D and F models were practically unarmed when it came to gunnery.

I was a Vulcan gunner in the Army back in the 80's and I can assure you they had any issues worked out by then, you're using the first generation attempt at something as a measuring standard, the GE M61 cannon is a vastly superior system to those multiple gun systems it replaced, lighter weight and a higher rate of fire in a smaller package than a 4 gun system. Those things functioned flawlessly every time we used them, stoppages were extremely rare, the vast majority of the time when we were at the range with 4 guns online firing all day it went without a single hitch or hiccup, in the 3 years I did it I can only account I single time that we had to use our reserve gun we brought along to replace one of the 4 guns initially put online at the beginning of the day.

Probably a good thing, the F-105 was not a very good aircraft as designed. The Thunderbirds used them for a half dozen shows, hated them then went back to the F-100. Terrible maintenance issues and in-flight failures crippled its original mission. As conventional bombers they were pretty much sitting ducks which a better gun would not have helped - and the fleet was pretty much expended in Vietnam with total losses approaching 50%. The aircrews who flew them were very brave men, but a better gun would have made little difference.

@@ww748 The F105 was an excellent aircraft as designed, in Vietnam it was being used outside of it's primary role which was to deliver nuclear weapons deep in the Soviet Union, and like every other F designated US aircraft used in Vietnam they all suffered from the rules of engagement that stated an enemy aircraft couldn't be fired on until visual recognition was confirmed, none of the US aircraft were designed to be anywhere nearly as close to enemy fighter's as the F105's, F4's and others were forced to because of that rule, by their original design they'd have dealt with enemy fighter's "over the horizon" before they got as close as they typically were during engagements in Vietnam, that's why before a new variant of the F4 with a gun could be fielded the existing F4's already seeing action over there had that hastily designed windmill powered gun pod put on them, it suffered from accuracy problems at any speeds over the slowest one's due to aerodynamic forces causing the pod to torque around and throw it's bursts everywhere except for where it was being aimed.

My father was wounded by 20 mm canon fire from an Me 109. He was a flight engineer who was moved down from the normal top turret gun to waist gun. On April 18, 1944 on a mission to Berlin, the tail gunner’s gun jammed and the 109 was able to approach and fire his 20 mm cannons. A round exploded when it hit dad’s oxygen tank, knocking him unconscious with shrapnel wounds. The other waist gunner game to assist by sharing his oxygen. The other waist gunner had 87 pieces of shrapnel hits on his front torso. Luckily they were mostly skin deep and he was released from the hospital before dad. The heavily damaged aircraft never flew again. The pilot returned the ship with four wounded and no fatalities. On another mission over Berlin, flack from an 88 blew a hole in the bottom of the plane - dad used to have a picture of the hole - and again suffered wounds from aluminum shards along his shins. The flight surgeon used a straight razor to “shave” the slivers from his shins. He flew 25 missions - at the age of 20.

The impact shown in the picture entered the cockpit and decapitated the pilot, Lt. Hal Minnerich, killing him instantly, and wounded the co-pilot, Lt. Thomas Sellers. Lt. Sellers was able, with the help of other crewmembers, to fly back to Ridgewell and land the plane safely. Lt. Sellers was able to complete his tour in April 1944. Tinkertoy was lost 20 December 1943 over Bremen after being struck by an attacking BF-109

Also ironically on 20DEC43, that was when the B-17 from the 379th Bomb Group named “ Ye Olde Pub” on its return flight from a mission over Bremen as well, was met up with a ME109 flow by Franz Stigler, who ended up giving the B-17 safe passage out of Germany to over the North Sea. The book published about the two pilots encounter is titled “ A Higher Call” and tells the stories of the B-17 pilot Charlie Brown & BF-109 Pilot Franz Stigler, who ended up being able to meet up years later in 1990. As many know there are videos about their encounter on You-Tube, a couple are great & others are not as accurate. Either way the book is well worth reading for anyone interested in this type of history.

It was so new that it's guns hadn't been harmonised nor had the squadron code letters been applied to the fuselage, it had a combat life of precisely 24 minutes as the cannon shell damage broke its back and it never flew again. Dunlop Urie was wounded in the legs, recovered and flew throughout the war.

During WWII, Commander J.P. Monroe, head of the armament branch of the Bureau of Aeronautics, in WWII had some thoughts about cannons vs machine guns: From a strictly “gun horsepower” standpoint, one American-clone of the British 20mm Hispano, (although not as good,) 20 mm cannon, like the one placed in the nose of the P-38, was roughly equivalent to three .50-caliber machine guns. “The 20 will go through .75 inch of armor at 500 yards, while the .50 cal will go through only .43.” He also noted that the significantly heavier cannon barrel was not as susceptible to being damaged/over heated with long bursts like the Ma Deuce .50. But the German 20mm HE "Minen" shells were significantly more powerful than even the British 20mm Hispano shells, equal to four or five .50 caliber machine guns, so some of the heavily armed Fw 190s with four MG 151 20mm cannon and two 7.92 machine guns actually had more firepower than a B -25 "strafer" gunship with 14 forward firing .50s!

More likely some kind of hydraulic or mechanical failure letting them drop a bit or something.

This is certainly informative but I've read that the Germans considered that the 20mm was ineffective against bombers and that lead to the development of 30mm weapons. It only took 3 30 mm hits to take down B-17s and B-24s.

In general, larger caliber shells have better ballistics due to improving volume vs surface ratio. In the particular example of the German Mk108, it had low muzzle velocity and resulting poor ballistics in order to fit on a WWII fighter.

@@jbepsilon Yes, but when referring to the Mk108 in a Me262 people forget the added velocity of aircraft. A Me262 on an attack run from behind on a B17 adds almost 400fps to the muzzle velocity related to the difference in speed between the aircrafts. Remember, the Me262 lauches the 30mm round at 850 - 900km/h. The muzzle velocity of a 30mm Mk108 is actually app 2500fps when fired from a Me262.

Not "ineffective", just that a 30mm would do the job better... and I disagree. By then the LW was using 190s with 4xMG151 20mm plus 2xMG131, plenty enough to deal with any bomber... BUT, the 109 could only fit ONE MG151 OR one MK108, so the choice was obvious in favour of the 30mm since you just need a couple hits to blow them to pieces.

Wow, some facts. A human speaking. No weird mood muzak. Even mentioning of survivor bias effecting perceived results. Survivor bias was for example, when you study returning planes for damage. You evaluate the hits and consider ways too protect those zones. BUT, those are aircraft that survived their damage. The planes that didn't survive needed the evaluation! I've heard of 20mm cannon used in aircraft since childhood, but never knew about their charge or fuse. A credit card thickness of protection.

@@johnmclean6498 P-38 armament was four .50s and one 20mm Hispano cannon, all in the nose. The Hispanos had problems with jamming and that meant that any wing mounted Hispanos that jammed in flight, couldn't be cleared until they landed on the ground, which was a major reliability issue for the US military. Since the P-38's guns were all in the nose, a manual unjamming mechanism was installed in the cockpit so the pilot could clear the jam in air. If the Hispanos didn't have the jamming issues, you may have seen more Mustangs, Hellcats, and Corsairs armed with 20mm cannons in the wings during WWII.
