Thing is, when you get battle damage to engines in most cases you're going to lose both engines in a pod - at which point it's arguable exactly what additional margin of safety you get from 8 engines in 4 pods versus 4 engines in 4 pods. Logically I would expect that to be the case but it seems not...

The problem is AFAIUI that if we hang one engine under the wing instead of two small ones, the thrust line from the large engine is lower than the thrust line from the two small ones and that causes severe structural and controllability issues. The only way to handle that is to replace both the two ...

That was when we good get a plane off the drawing board and into production in a few years, not decades. I suspect that pushed to it, we could get a bare airframe and engines off the ground in a few years (which is by our standards what those old aircraft were). Its the systems inside that take the...

Even leaving aside the great chasm between American Chinese and Chinese Chinese food, I'm sure more than a few of the sailors weighed "not the same food we've eaten for the last 20 years in our home village/town/city" heavily in deciding to join the crew. :) Apparently the logic is that W...

Regarding the B-52... Are they ever going to replace the engines? I doubt it; there are a lot more problems than it might seem including such esoteric things as thrust lines. From what I can understand, the re-engining would essentially mean a new wing. [quote]Gallagher carefully led the three-gene...

The other US choice, though, the 1917 Enfield is distinct, and a very nice rifle.


It's pretty much a rechambered British P-14. A very nice rifle though; the British Army used it for sniping.

In case you are interested in domestic manufacture I throw in the Italian Mannlicher Carcano. If this is right it was rather easy to make. A big plus for a country with a limited industrial capacity. Mannlicher actions did not perform well in service conditions; one of those cases where something t...

Ironic isn't it that the support vessels model goes straight back to the 17-18th century :D Not really, it was a good model and it's never really gone away. (STUFT and all that). The US Navy did much the same thing in WW2 when it took up a lot of tankers from trade and turned them into auxiliaries....

I was thinking about the six RO-RO ships (T-AKR-5051 to -5055 and -5059) that have been at Joint Base Charleston for many years, although they are moved around occasionally. Not really inactive reserve, but not really active either. They're MARAD ships, not Navy and the Navy would only take them ov...

What about things like logistics ships, that have a minimal crew and just sort of hang around in port for months on end waiting for a crisis in some other part of the world? These days they're usually leased. That has a lot of advantages in that the Navy can lease enough ships (and their crews) to ...

How on earth did the Gates get its spine 6 inches out of true? Was this a construction defect, or did something happen during deployment that was not recorded where I can easily find it? She was built that way. Construction error. That's why she went after only 18 years in the fleet. What I don't k...

(reads replies) ...Yeah, that's kinda what I thought. The fella who tweeted this (want to leave it at that, the info was posted on a private FB page) later said that for just $550M USD each they could be SLEP'd and given VLS. As soon as I read that, I knew it wasn't happening. Mike Well, doing just...

The other two have already gone, one scrapped, one sunk as a target. The three left are in a hell of a mess. They've been stripped clean, gun...

Those diddly little German hatches were not nice to get out of, for sure. Wasn't the loaders hatch in the side of the turret and only accessible in certain loading configurations? The real problem was that was the only accessible hatch for the entire crew under some conditions. Five people fighting...

I particularly like his "Oh bugger the tank's on fire" test. How quickly can the crew bail out? That's why he didn't want to go to war in a Panther. Getting out in a hurry is really hard.

I've watched part one. The Chieftain's Hatch series is extremely good and very iconoclastic. His description of the T-34/85 was a classic "This tank serves the interests of the state, not its crew" and the Panther "personally, I would not want to go to war in this tank."

Didn't the first US missile subs have the 'surface, assemble, elevate from horizontal, launch' configuration ?? None of the ones actually built did. The early design studies using Jupiter had an arrangement a bit like that. I'm pleased no-one weaponised the FLIP-SHIP design, used as a stable platfo...

There's a whole clutch of cartridges in this bracket. 7.65x55 for example was quite popular for a while and is regarded as a very good solution for its day and is viable even now (its reckoned to be virtually identical to the modern 7.62x51). 7x57mm was very highly praised and came as close as anyth...
