Re: Royal Navy Super Battleships and Battlecruisers

Hi Dunmunro, I guess it then boils down to which RN document one chooses to subscribe to. I did not, as you know, make up the cited range numbers (which dated from 1942). A transcription of the original RN text was post on KB about six(?) months ago IIRC. Byron I don't recall all the particulars, e...

Re: Royal Navy Super Battleships and Battlecruisers

Re the accuracy of Hood’s opening gunnery, the relatively early model of RDF Type 284 she carried - when employed for FC ranging purposes (as opposed to surface search) - was only considered “effective” at 16-18,000 yards. B This is an except of HMS Hood's Type 284 radar trials using KGV as a targe...

Re: Royal Navy Super Battleships and Battlecruisers

Gentlemen, Re the proposed super battleships and Battlecruisers, i can understand why in the 1920's they wanted to build very powerful battleships, but regarding the 'Super battle cruisers, it was pointed out in another topic that the point of having battlecruisers was to chase away enemy cruisers....

Re: Erroneously landing on an enemy aircraft carrier?!

In May 1942 it appears that IJN aircraft may have signalled a USN carrier in an attempt to land on her: USNI Report on Coral Sea: The combat patrols were landed well after sunset. In the case of the Yorktown, this was begun at 1858 and completed at 1930. While the fighters were in the landing circle...

Re: the main armament of the General Belgrano

Gentlemen, Just looking up the main armament of the Argentinian cruiser General Belgrano it states that she carried no less than 15 x 6" guns, i can only find a very indistinct photo of the ship, so I wonder how these guns were distributed on what was described as a 'light cruiser' of only twelve a...

Re: Hood and PoW crossing the T of Bismarck and PE

Gentlemen, Looking back over the topics we have discussed many times the 'what if' factor in the Denmark Strait battle, including what would have happened if Hood had made her turn earlier and not been hit and what would have happened after. I have often wondered what the result would have been had...

Wondering if radar-equipped ships called target bearing for less well-endowed units?
Sending range information would have been more useful since optical bearing accuracy was typically better than radar could provide.

Re: Optimum speeds for destroyers in gun battles

This is from: New Eye for the Navy: The Origin of Radar at the Naval Research Laboratory Records do not show the exact situation on December 7, 1941. However, a complete survey of what equipment had been installed and what delivered was made less than 2 weeks later. It was summarized in an internal ...

Re: Optimum speeds for destroyers in gun battles

The Mk4 on USS Roe was a prototype which may have been removed. AFAIK no production variants were installed on destroyers until after 7 Dec 1941: Initially, from want of experience against an enemy attacking with the persistence demonstrated by the Japanese, our antiaircraft batteries were inadequat...

Re: Optimum speeds for destroyers in gun battles

"But what of their accuracy, on a mill pond, all fine and dandy I’m sure, however in heavy seas, crewmen man handling shells, gunnery officers trying to judge ranges, while the ship must have been pitching and rolling about, it couldn’t have been good." Accuracy would have been all over the landsca...
