If you don't hear an idea like that and think, "what if we use a bigger bomb and make the crater bigger?" then you don't get WWII bombing planners.
AFAIK that was why the Tallboy was used for cratering; 500lb bombs make a lot of little craters that can be filled in with standard earth-movers, but a 6 ton bomb that makes a crater 80 feet wide takes a bit longer to clean up.

This seems appropriate for this thread.

I'm a little curious if any of this manual gunnery stuff is still being taught. Maybe not bomber gunners, but do people still learn how to do anti-aircraft fire? Or has that been entirely replaced with radar-guided missiles and guns?

I have heard (cannot source) that the dummy loads used for testing had a different density to the real explosive, producing a different impact force and thus invalid results.
AFAIK NTS Newport did test the Mk14 with a light load in order to ensure that the test shots had positive buoyancy, so they'd be easier to retrieve after tests. That caused problems with the depth-setting, though, rather than the impact fuse.

The impact fuse had problems as a result of being designed for a slower torpedo, that impacted less forcefully, and also not being properly tested on the Mk14.

Sorry, I used a bad example. Perhaps tanks would work better? The gist of it was that manufacturing capability beats technical excellence. The perception at the time being that the Germans had all this neat stuff and the allies didn't, but maybe a lot more of it would balance things out?

The usual line there is that "It takes 5 Shermans/T34s to beat a mighty German Panther, and the Allies built 6." but a) IIRC in combat that's not true, especially for later models of the Sherman/T34, b) out of combat, one Allied tank that shows up beats any number of German tanks that are broken down in a ditch, and c) the reason Allied tanks fought German tanks 5 on 1 when they could wasn't cowardice, it's because you send tanks as part of an entire company rather than 1v1 duels.

However, there is the nugget that American and Soviet tank manufacturers built with an eye for mass manufacture, while the German manufacturing process was made to accommodate commanders fiddling with the design and hurt productivity as a result. See Jonathan Parshall's lecture here, at around 27 minutes if the timestamp doesn't work.

Well, maybe. Who can say? I'm just asking questions.

Most people have no idea how bad or dangerous these animals are. They see them in zoos and Disney films and think they are cute. Arent they are top man killer in Africa?
Apart from humans, and disease vectors like mosquitos and snails, hippos are definitely one of the killingest animals around. They're responsible for around 500 human fatalities per year, compared to 200 for lions.

I'm trying to find this myself and coming up short(heh), so- Did the Soviet Union do a study after WWII where they determined that making a tank taller made it significantly more likely to be destroyed, thus creating one incentive for very compact tanks? I was sure that they did, but I can't find it right now.

There's also strategic and operational factors in that if you make a tank lower and you are making tens of thousands of them, you are saving very large amounts of steel and also making the tanks that much lighter, which in turn reflects on logistics, what kinds of roads and bridges they can use, et cetera.
Yeah, those are some of the other incentives. I'm specifically looking for a study I saw somewhere that said "TALL == DEAD".

What happens if you shoot a torpedo at it? Is it going to be a Halifax Explosion type thing where it's just impractical to cordon off a safe area and blow it all up for good?
So far as I can tell, yes, including the risk of a minor (on the order of 20ft/6m) tsunami going upstream to London, to say nothing of the nearby towns it would wreck on the Thames Estuary.

It shows up more on the civilian violence side: off the top of my head, sword and buckler (a buckler is as much a weapon as a shield in how it's used), sword and dagger, sword and cloak all show up in various fechtbuchs and assorted period writings. We have something like one account of Cherokee fighting with long knife and tomahawk on the more military side of things.

Also in terms of blade+gun, the Apache revolver. A pepperbox revolver with brass knuckles for the grip and a fold-out knife.

Though I do appreciate this comment.

quote:

The revolver also has a design constraint when opening the barrel: by default the barrel points back toward the knuckles of the user. Thus, the user has to remove the knuckles, rotate the gun to point forward to the target, and then shoot. Certain defense scenarios might not accord the liberty of time to perform such an involved maneuver.

isn't it generally agreed that the Israelis and South Africa teamed up on a test in the southern ocean at some point?

Officially uncertain and classified, but a lot of people think it was a South African-Israeli nuke
