I was amused by the numerical precision given for penetration at 7:12. E.g., its says concrete 12 inches and brick 13.5 inches. One thing that was clearly demonstrated to us when I did engineering at university is that there is considerable variation in these materials. In the 1940's in advanced western countries such as the US or Australian, most concrete was machine mixed - such concrete meets specific specifications. But in Germany most civilian construction used hand-mixed concrete which typically has strengths less than a third of machine mixed concrete. They would have taken a lot more care on military fortifications. The strength of house bricks also varies over a considerable range.
Bricks _and_ mortar, and the type of pattern ('bond') the bricks are laid in - 13.5" is two-plus courses of brick, so the pattern and/or ties used would make a huge difference to the strength of the structure
@@williamchamberlain2263 : Very true. We saw that demonstrated in masonry class - 2-course flemish bond for example has a heck of a lot more strength than 2 adjacent plain bonds. Other factors are the type of mortar used, whether the bricks have concave surfaces or not, spacing of thermal expansion gaps, use of pillars, etc. All things considered, it is quite ridiculous to specify a bomb penetration to 2 figure precision, let alone 3 figures as quoted in this video.
@@keithammleter3824 Its likely the specifications for the wall used in the example are listed in one of the pages not shown. They get incredibly specific in those ordnance reference manuals due to the near constant det tests they were conducting.
@@JamesGrim08 Good point perhaps. Specifying masonry is not at all like specifying metals. If a certain alloy is specified to have a tensile strength of so many MPa, that's what it will be within a percent or less. but with masonry it varies +,- 20% at best. In the construction industry, just the minimum required strength is specified.
The 4000lbs bomb doesn't just have a 2.2x wider circle, that circle's area is almost 5x the area for only 2x the payload of a 2000lbs bomb. Seems if the objective is the most building destruction you want 4000lbs bombs.
outstanding coverage.......cheers from Orlando, Florida, Paul...loved seeing the document from Orlando......I spent a lot of time at that base as a youth in the 50's and 60's.....
Thanks for this one. I wondered what this research on bomb destructiveness would reveal. I wrote about the only study on an accidental bombing of Korean fishing boats by 93rd BG flying out of Okinawa in a training exercise at the island of Dokdo off the East Coast of Korea in June 1948. The bombs dropped were the 1,000 lb. AN-M-65 General Purpose bombs, not "blue devil" M-38 smoke bombs normally used for gauging accuracy of individual bombardiers. The Korean government claimed 55 deaths at the island, but it is likely that many more died.
11:55 I think that should be able to penetrate a concrete slab 1.5 feet thick, not 1.5 inches thick. After all, the title of the chart is: Probable Maximum Thickness of Concrete Perforated (FT.) by G.P. Bombs from altitudes above 5,000 FT.
Of note is the effect of the curved nose shape redirecting the bomb sideways. Modern GP series with a longer ogive tend to go much straighter which along with guidance packages makes slight offset attacks on hardened targets a regular setup.
this shit is so well researched. i find myself pausing to look over the documents only to have them explained clearly and concisely only moments later. you're amazing at what you do!
Saccuracy was the biggest variable back in WW2. You’ve got to ensure your weapon impacts close enough to whatever target you want to hit. These days, with smart bombs like JDAM, this is not an issue. Kind of a waste of ammo, though.
I presume Robert McNamara had a role in producing some of the wartime statistical analyses of AAF mission effectiveness. These led to the belief that bombing of Laos, Cambodia and Vietnam MUST inevitably defeat the NVA and VietCong
Probably correct. He really loved statistics and numbers and charts. At the expense of common sense. There is a lecture here on YT called MacNamara's Morons. Truly scary that the policy existed,and that he never altered his opinion of it,till the end of his life. What that says about other of his plans makes a person wonder. He came up with many ideas,but his personality was such he needed someone senior to periodically sit on him and redirect at least some of them. That did not always happen.

Even bombs getting close enough to a bunker could casualties from pressure and maybe fragments. Napalm would also be a threat especially if some got in through the ports.
Previous videos have covered this, and other places, but no, not really. You need very specific weapons and application of weapons to beat a bunker. After all, no one would use em if they were easy to beat!
Okay, so 500GP, at 16 feet only 50% die! 16 feet!!! You are 'blown away' yet live to clean your shorts. One detail not clear here is where the bomb is detonating, most bombs burrow into the earth before going off, even with 'instant' fuse setting. Do you know if this 16' took into account if the bomb was partly buried? Great content
Actually shock waves are caused by high explosives. The shock wave is because the velocity of detonation exceeds the speed of sound. Technically speaking, high explosive doesn’t ‘explode’, it detonates. So petrol tanks can be said to ‘explode’.
@@AndrewBlacker-t1d there is effectively a range of events ranging from combustion to detonation. Look up the term ‘bleve’. It’s basically what happens in a petrol tank explosion.
General purpose means it can be used on any target not hardened or reinforced. For the latter, you'd want semi-armor piercing or armor piercing which have thicker bomb casings allowing them to penetrate such targets. This comes at the cost of the SAP and AP bombs having considerably less explosive filling as compared to GP bombs of the same weight class.
@@primmakinsofis614 he knows;) he's just making a kind of a wordplay joke, that a bomb being that heavy makes it special purpose in itself (again, in colloquial meaning, not actual nomenclature)

Mum and dad survived German bombs in WW2 Manchester UK. They were anti war. When dad later did handgrenade practice in the British Army his nose bled from ptsd. I guess bombs have an effect even if they miss you.
Even near misses from the other, smaller bombs would mostly likely damage the tank and rattle the crew. Damage to tracks, running gear, maybe the barrel, and vision blocks could cripple a tank. Accounts of radio antennae being sheared off even by artillery are also common. However, ground attack planes using napalm would be a nightmare for tankers.
Fascinating technical data, i.e., considering the limited availability of computer - aided calculations and cyber cerebral power during WW2. Quite interesting, albeit within the realm of human conflict / destruction and tragedy.
Only on external racks; the largest bomb that could be carried inside the bomb bay was 2,000 lbs. The external racks were rarely used as the drag and handling penalties associated with hauling bombs externally was judged not worth the increase in payload.
Doctors need to calculate Body Surface Area (BSA) when prescribing certain drugs and chemotherapy agents which are excreted by the kidneys. Ideally they should base dosage on kidney functional area, but it has been found that BSA is close enough. Typical male white or negro male BSA is 2 square feet. Asians a bit less. Google Body Surface Area. In actual fact, if a bomb goes off near you, only one side of you is exposed, so the exposed area is only one square foot plus a bit more due to ricochet.
Most likely those were U.S. bombers that did the ‘shuttle bombing’ missions. They took off from Britain, bombed their target, then flew on to land in Soviet controlled territory. They would then refuel, re-arm, and hit another target on their way back to their home bases.
That was the 4,000-lb HC (high capacity) bomb. Its cylindrical shape made for terrible ballistics. The British also had a 4,000-lb GP and 4,000-lb MC (medium capacity) bomb which had traditional streamlined bomb shapes, but these carried far less explosive filler than the HC bomb. The 4,000-lb HC was mostly used in the raids on German cities.
Edit: The units of 500 G.P. Bomb concrete penetration should be in feet, not inches.
When it comes to it, is there a difference?
8:07 while doubling bomb weight doesn't double demolition radius (33/20=65% increase), it does however more than double demolition area (1089/400=172% increase).
Your videos are like a reference library. The detail you go into is always accurate and always backed up with proof. Thanks 🙂
The 1000lbs bomb may not have double the radius of destruction of a 500lbs bomb but a 65% wider radius results in a 2.7x larger area of destruction.

This episode was a blast. Thank you
8:05 notice that doubling the bomb size more than doubles the circular area of demolition.
The 2000 to 4000 even more than doubles the radius. I would not have expected that result.
The 4000lbs bomb doesn't just have a 2.2x wider circle, that circle's area is almost 5x the area for only 2x the payload of a 2000lbs bomb.

The effect on humans if you launch a 4000 lb bomb at them. I don’t think you need to look through documents to find the answer to that one chief.
Saccuracy was the biggest variable back in WW2. You’ve got to ensure your weapon impacts close enough to whatever target you want to hit. These days, with smart bombs like JDAM, this is not an issue. Kind of a waste of ammo, though.
The point is to estimate the lethal radius of blast and frag from any particular bomb. We use that to plan safe evacuation distances.
