Re: Interesting Bomber Data Outcome...

.... Range (Combat Radius) in miles (not knots): 4480, 3445, 3200 ... Why would anyone measure range in knots? Nautical miles are more commonlly used than either stat miles or kilometers in navigation and especially aviation, because it's based on the longitude and latitude segmention of earth mapp...

Speaking of Stealth, here's an interesting web page writing about some early research:

For some interesting background history on the B-1 and what a huge waste of tax payer's money it is, I would suggest reading one my favorite books: "Boyd;The Fighter Pilot Who Changed The Art Of War" by Robert Corum. This excellant book also gives some insight into how dysfunctional and de...

..... How about the possibility that the 16" AP Mark 8 simply had excellent performance vs deck armor? Most of the extra weight in it's design was dedicated to making it better able to remain intact when penetrating armor, right? I think any modern battleship projectile is a very potent weapon...

... though her inner IZ should be much better due to the sloped deck. Her turrets in contrast seem vulnerable at almost all ranges to main calibre hits. . Against 15" projectiles, I once detemined that they had some immunity between 20-30km, but just barely. Regarding the JB hit: As I recall t...

According to the formulats at http://www.navweaps.com/index_tech/tech-045.htm 1.5" should decap everything up to 18.6"... George Elder found extensive Italian research on decapping, and the Italians found that it required greater thickness than that to insure de-capping of large projectil...

[From what I've read penetrating an armored layer tends to change the projectiles course toward the normal not away. ... . Yaw is not the change in trajectory upon penetration. There is trajectory change more toward the normal (some programs drastically over estimate this, or fudge this, to obtain ...

The article I read doesn't match the IZ results from the GKdos100 copies I have.

I find it hard to believe that all the German designers and engineers got it so terribly wrong.

I certainly do not believe that Bismarck's protection was up to providing protection vs large projectiles to any range, and I doubt that Thomas holds such a view either. Primary documents dating from circa 1936 state that the IZ was to be from 20-30km vs 15" projectiles. That is certainly a rea...

According to Derek Howse (a noted Britsh expert on WWII naval radar and involved with the ASE at the time), Scharnhorst had a Hohentwiel search radar. Frank Rueter also claims this. I find Howse's and Rueter's claims very plausible, because the Tirpitz had been equipped with a Hohentwiel prior to th...

Scharnhorst seems not to have benefited from this supposedly superior German radar. In fact, as far as I know the Germans weren't even using the surface search radar with rotating antenna used by allied forces. Didn't the Germans still have to scan for targets using their main fire control array? Y...

Lutscha, Some period US documents refer to the "bomb deck" on the fast battleships as a "yaw deck". That opens up a new possibility as to it's actual purpose, and if it does induce yaw, then there would be little to no reduction in the sum effective thickness caused by using two ...

Even if the radars quality wise were close to each other the allies had a much better doctrine and a lot more experiance... The German Navy was gaining radar experience years before the Allied navies even had comparable radars in service. The German Navy obtained a lot of war experience in the use ...

A spaced array armouring scheme may be able to better deal with a projectile that is difficult to defeat at longer ranges using more conventional techniques, because it can potentially destroy the projectile, render it inert, or otherwise prevent it from penetrating intact. It also introduces fuzing...
