Re: Naval communications in WWII
. The RN used "ordinary" land (sea) to air voice sets, but later used US supplied TBS sets. Various messages were coded/cyphered, ranging from simple card codes through daily codes and Typex and Typex/CCM (this was compatible with the US ECH Mark II). In addition lots of code names, code p...

Re: Was the battleship Bismarck really the best of its time?
. Yet again. As everyone know, but for some reason seems to forget, there were NO, repeat NO, absolute measures of either shell "strength"/"penetration", or armour "strength"/"resistance". These were only really measured on a nation, by nation, basis of firing...

Re: Raumotters to the Rescue
. Most (all ?) WW2 battleships had paravanes and cutters which they could stream to help protect themselves. Each navy used their own favoured system of deploying them. Examples are the "original" trawler-like way of streaming from the fo'c'sle, but due to the large draught of most battles...

Re: bismark-after torpedo hit

A paravane is streamlined, which is not what is wanted. You need drag, which in those seas is a disaster for the towing rig.

Re: bismark-after torpedo hit
. Paravanes (pairs) made the modernised British battleships and KGVs lose 1 to 2 knots depending on which set-up was used. The other (possibly) available minesweeping item available might be an otter board (used in some minesweping arrangements) but again this would have a very small effect. What ha...

Re: bismark-after torpedo hit
. The British (and presumably all other mariime nations) had properly designed ocean going tugs, however they were built for producing pull and manoeverably rather than speed. The real problem was the size of the seas and the strength/durability of the cables. Passing the cables would be difficult, ...

Re: Idiots guide to....
. Contrary to what many interested parties imply, in WW2 (and earlier) there was NO absolute measure of the properties of shell, versus armour (and vice versa). Yes there were acurate measures of metallurgy, hardnesses, etc... but these were not definitive as they were usually destructive and only s...

Re: Bismarck's propulsion damage
. Only a grain of truth in the story. ABC said in a letter that the rear placement of the "Queen Anne Mansions" led to a certain amount of windage. however that anyone with a knowledge of sailing a dinghy should be able to handle the ships. The poor handling "story" came about wh...

Re: Bouncing bombs against ships
. Highball was highly rated, after tests the RAF assessed them as twice as effective as torpedoes, and the aircraft attacked at a much higher speed. When 618 squadron was sent to the Far East they took three hooked photo-reconnaissance which were rated for multiple arrested landings and the Highball...

Re: Tonnage and Displacement

And, just as a gentle reminder, the displacement will vary with the density of the water that the ship is floating in (see, for instance "plimsoll line")

Re: The Swordfish's Torpedo misses Bismarck
Were the RN submarine patrols outside Brest at this time ? Would Bismarck go to Brest or Saint-Nazaire to repair the bow damage ? What destroyers were based in Portsmouth and Devonport that carried torpedoes and could attack ? Would Bletchley Park decode the instructions to Luftwaffe units to protec...
