Re: Hypothetical: The British detect Bismarck with a ship-borne Walrus at 0900 on 25 May 1941.

Hi Michael L I think Court Martial(s) would be the subject of a separate Post - if it hasn't already been done. Have you searched and read by far the longest ever thread here? Yes it's been done. Done to Death. :cool: I think if Tovey had considered "run out of fuel" to be an actual bindin...

Re: Titanic tourist submersible goes missing with search under way

Hello All, Having seen a video widely available on the web, this submersible seems IMHO to be an amateurish bodge-job, with only the pressure hull of professional standards. It uses a Playstation controller to run its internal systems. :shock: Looking at the sparse external fittings it seems unlikel...

Re: Hypothetical: The British detect Bismarck with a ship-borne Walrus at 0900 on 25 May 1941.

Hello All, Just to be clear, I believe we have established that the towing signal was actually sent during the final battle, at Churchill's insistence, after the battleships had been engaging Bismarck for some time. I have shown a hand written letter from Tovey to Pound sent on arrival in Scapa indi...

Re: Titanic tourist submersible goes missing with search under way

Hi All, There are muddled (uninformed) references to using radio underwater *, but my understanding is that these deep diving units use acoustic transmission for comms which can struggle at great depth (ie range) and can be be cut off by shadowing by the wreck's hull.

Re: Hypothetical: The British detect Bismarck with a ship-borne Walrus at 0900 on 25 May 1941.

Hi Michael L, We are at the sensitive boundary of naval tactics and politics here. The actual timing and origin of the "towing" signal has been debated at length on this site. It was pure Winstonian hyperbole, dictated to and forced upon Pound under extreme pressure as the Prime Minister w...

Re: Shipborne aircraft - Walrus and Arado AR196 - Lost Opportunities?

Hi Michael L From Ellis' report on Suffolk's operations in ADM 534/509 During the turn at 0325 the wind, now force 6, carried away the securing gear of the controls of the only aircraft on board , which was on the catapult, causing damage necessitating extensive repairs which took some days to compl...

Re: Shipborne aircraft - Walrus and Arado AR196 - Lost Opportunities?

Hello All, As has been observed, the weather conditions during the Chase were extremely poor and it would have been almost certain that an aircraft launched would be destroyed on attempting to land on the sea for recovery. The Arado design in particular suffered from engine failures due to cylinder ...

Re: Chaser Gun on Paddle Steamer

Hi All, They had to reposition standing rigging for it to fire? Amen to those answers above. It was more a case of clearing the windward sheets to the jibs out of the way. Also we are not talking about the virtually continuous naval warfare of the 18th and early 19th century. Some of these vessels p...

Re: Chaser Gun on Paddle Steamer

Hi All, I think is a conjectural model of HMS Birkenhead, which was one of the first iron hulled RN warships. However as answered elsewhere, these frigates were downgraded due to worries about fracturing under enemy fire. Re-designated as a troopship she was completed with a built up foc'stle she wa...

Re: Estimating torpedo energy and resistance

Hi All, Marcelo is 100% correct The drag/resistance actuating in the opposite direction will increase with speed, till the point that thrust equals resistance, a sort of horizontal free fall terminal speed. You can not go beyond that point if you do not increase thrust. Drag: Square Law Rules Imagin...

Re: Why built useless battleships?

Hi OpanaPointer, Since Churchill re-used his turn of phrase from a speech of 1912 in his very popular books written after the First World War it seems likely to me Holger Herwig consciously or unconsciously quoted him when he wrote his own book in 1980. It is of course arguable that if Germany had q...

Re: Why built useless battleships?

Hi Opana and all, On this anniversary of Jutland we can consider the origin of the description of the High Seas Fleet as a "luxury" as adopted by Holger, but surely originating with none other than Winston S Churchill. In a speech in 1912, on becoming First Lord of the Admiralty: The purpo...
