Re: HMS Hood & USS Arizona Magazine Explosions

Here's another interesting magazine explosion: HMS Barham. She was torpedoed, & in her sinking her magazines exploded. It's been attributed to her 4 in AA ammunition touching off the 15 inch magazines. It would seem 4 inch ammo The video of the explosion is quite clearly caught on film, and the ...

Re: Battleship Vanguard Armor

What do you mean by "underneath her" ? Torpedoes that come up vertically and hit the ship exactly at her maximum draft ? The most devastating torpedoes are those designed to pass beneath the target and explode some meters below the keel triggered by the magnetic field. In addition to the ...

Re: Battleship Vanguard Armor

My question was more about the survivability of Vanguards structure against the weapons. could she survive a spread of 4 torpedoes blowing up underneath her? Her broad flat double hull near the keel seems to be her weakest point in the grand scheme of things, a hold over from the days where her only...

Re: Battleship Vanguard Armor

Well, I'm back after a somewhat long hiatus. I guess what I'm curious about in all this is the idea of influence detonations. I know both the US and the Germans tinkered with magnetic detonators that were meant to permit the torpedo to blow up UNDERNEATH the vessel and break its back, at which point...

Actually, Mr. Rather, that is everything I was looking for to explain it.

Thank you very much.

What is a depression rangefinder, who used it, and where?

I found this thing on one of my ebay walkthroughs, which I do when I'm bored and I'm looking for something to give me something to chew on. This one just took me aback by a mile or so. Any information that anyone would be willing to scare up on it would be greatly appreciated, so I can understand it...

Looking for an instruction manual...

So, as of late, I am the proud owner of a Soviet ZDN-1 Stereoscopic Rangefinder. Unfortunately, among the list of missing items in the box, was the instruction manual.

Anyone one know where I could find an instruction manual for it???

Many thanks in advance.

You do realize that the thin martian atmosphere is mostly co2 and the temp is always below zero F? What was it Kennedy said about the moon... Something about "We don't do it because it's easy, but because it's hard." Do I have that right? And there's the link so you can see this project f...

A chance to be a figure in history...

So I've decided to submit an application for Mars One, a mission that intends to put people on the Red Planet by 2023.

The catch is that if you go to Mars, you are staying there, permanently... A "One Way Ticket".

Here's hoping that I can beat out thousands of other people for a slot.

Neubaufahrzeug.

Anyone ever heard of this one?? It was built in the mid 30s, and was a multi turret tank design that the Germans had been working on. Its armament consisted of a 75mm gun, a 37mm gun in a single gun mantlet, and there was a machine gun turret (identical to the one used on the Pz I) in front of the m...

PT Boats: Unqualified success or mediocre at best??

"They Were Expendable" and "PT 109" are some fairly well known movies, and even "McHale's Navy" focused on them. And then there was this great debate on the fight for Guadalcanal that largely sums it up into "Five Battles"... I've got a copy of Bern Keating's ...

Ok, If I understood this right... Howlin Mad screwed up big time by telling an Army General he had to earn an Army Division back... THATS the big controversy point that I saw here. He further messed things up by apparenlty never having taken a tour of the frontline, something the DIVISION COMMANDER ...
