Re: Propulsion less torpedo

Mmmm....I don´t quiet agree. In the mentioned site there is a picture of a launching, the "torpedo" was launched almost horizontally, question would be how far would the bare inertia take the torpedo before it goes to the bottom or comes to the surface, according to if it is hydrostatically positiv...

Re: Updating the KGV class

Too late for an edit. We also have to remember that PoW was being hit and near missed continually, with each near miss drenching parts of the ship with tons of seawater:

Re: Wind Behavior: 0400 - 0600

I'm certain that they stated true wind in the log. Here's a device to extract true wind from relative wind:

Re: Propulsion less torpedo

I think they were used as mortars, but the concept is very similar to a DC thrower.

Re: Updating the KGV class

I find it simultaneously fascinating and dismaying that this discussion has somehow morphed into a competition between the KGV design versus American battleships. I do not recall Dr. Brown mentioning anything whatsoever in that respect. Prince of Wales' DCT 15-ft rangefinder was quite unlikely to h...

Re: Updating the KGV class

Like Byron, I consider the opinion based on all the wartime experience garnered over time regarding all the ships of the class by D K Brown to be more valuable than the single trials experience of Constructor Pengelly. Quite so, Sean. Trials are customarily run in as good weather and smooth sea sta...

Re: Updating the KGV class

Fellow Contributors, As I recall assertions that McMullen's memories were at fault mainly revolved around things he remembered when speaking to Tovey about things the Admiral might or might not remember correctly. I do not think anyone has seriously questioned or identified major faults in his acco...

Re: Updating the KGV class

Fellow Contributors, With regard to spray over the bow at Denmark Straits, McMullen has this to say: The story as far as I can remember is as follows. Y Turret was "wooded" as "A " arcs were not open. A rough sea and strong wind on the starboard bow together with our high speed resulted in a contin...

Re: Updating the KGV class

After their 1944 re-fits, the standard displacements of the surviving KGV's grew from approx 35,500 tons to 39,500-40,000 tons. As a result, the ships operating with the British Pacific Fleet displayed very wet behavior compared to US battleships (Iowas, IIRC) sailing in company. I'm still hunting ...

Re: Updating the KGV class

According to Prinz Eugen's KTB, the Denmark Strait action was fought in Beaufort Force 4 wind conditions (Moderate Breeze - 11-16 knots out of the NW), reducing to Beaufort Force 3 ( Gentle Breeze - 7-10 knots out of the E) sometime around 0600 hours. The principal sea state feature was a residual ...

Re: 'QE' and 'R'class ships

Gentlemen, Yet another couple of questions for you I'm afraid! i was looking up the QE and R class ships and cannot really understand why the 'R's' were built except possibly in an effort to save some money as they were smaller and slower than the ships they went before them and seemed inferior to ...
