Re: Need help with WW2 Torpedo performance.

The torpedo protection of a modern battleship is about 5 m wide, that is why it is very difficult to sink a battleship with a couple of torpedoes, they just explode away from the vitals, they can not penetrate the hull as a shell does. On a cruiser it is almost imposible to find 5 m on each side for...

Re: gun placement on battleships

Confirmed, it was X. Paul, reality is that few Dreadnoughts were designed with all guns forward, AFAIK there were this and the two French. It means that always the navies liked the possibility of shooting astern, no necessary needs to be a running fight, an enemy may approach from the after arcs und...

Re: gun placement on battleships

A, B and C would make more sense. I will check R.A. Burt for confirmation.

Re: gun placement on battleships

It is a liability:

-dead astern arcs can not be covered
-a single impact that would affect the forward magazines (supposing the ship survives that) would disable 100% of the primary artillery

Re: gun placement on battleships

The disposition of the turrets in Nelson was a weight saving measure, nothing related to offensive, in fact it was not repeated in the post-Nelson´s KGV class.

Re: Type 93 torpedo longest range hit

That already exists:

https://en.wikipedia.org/wiki/Type_93_t ... 93_torpedo

Can we compile the number of torpedoes fired to achive this?

Re: Type 93 torpedo longest range hit

How many of those were close range shots against unaware non-manoeuvring merchantmen? Some even at night from the surface a few hundred metres away.
Most of them!

Re: Type 93 torpedo longest range hit

Firing at such unbelievably long ranges would have been a much more viable matter if the integral acoustic guidance system developed by the Germans for the "Gnat" could have been fitted to the Long Lance. It would requiere a totally new torpedo. The German could develop the GNAT because they alread...

Re: Type 93 torpedo longest range hit

The torpedo is a deadly weapon, the Uboats achived a 20% hit rate, which is quiet high, specially comparing to artillery. The caveat is that it is so as long as the target does not know it was launched and it was not manouvering, then the hit rate diminishes dramatically. There were more than 150 la...

Re: Type 93 torpedo longest range hit

Hi Wadinga:
I am going to read up on this as it says a lot which can apply about what happened at Denmark Straits.
What happened in DS?

Re: Type 93 torpedo longest range hit

Yes, the TDC has an input for range, but it is at the only effect that the impact would not ocurre outside weapon range. Same for the German equivalent. Look at this part of a German Uboat war diary: http://i66.tinypic.com/2nknxc0.png It says: Three torpedoes from tubes I, II, IV , launch parameter:...

Re: Type 93 torpedo longest range hit

Yes! Another exception is when the torpedo is fired with a large gyro angle (ie: the torpedo is to make a large change of course after being launched), in which case the range is needed. For a derivation of the equations, I suggest https://www.amazon.com/Fleet-Submarine-Torpedo-Data-Computer/dp/0974...

Re: Type 93 torpedo longest range hit

"You don't know the range, course or speed of the target"

Wadinga, for torpedo shooting you do not need the range, it does not enter in the calculation.
