Re: Bismarck/Tirpitz = most powerfull European battleships

Just to be mentioned that it seems quite curious that the longest range hits from naval guns were obtanied by: 1. European warships: a. Schanhorst on HMS Glorious at 28,600 yards in it's third salvo. 1940 b. HMS Warspite on RN Giulio Cesare at 26,054 yards. 1940 c. Spanish Heavy Cruiser Canarias on...

Re: Bismarck against BB-57 South Dakota

..... The Br 16in Mk 1 with Mk 1 rifling had a new gun MV of 2,575 ft/sec. Byron Campbell states 2586 fps as the Mk 1 new gun MV. At the beginning of Rodney's action 6 guns averaged 36 EFC at the start and 3 averaged 125. Where Rodney's guns "new" in 1941? What does EFC mean ? EFC = Effec...

Re: Bismarck against BB-57 South Dakota

16-in. Prolonged Firing by "Rodney" Rodney was allowed 30 rounds per gun with full charges with the primary object of testing modifications in the shell handling rooms and the performance of new 8-ton obdurating pages. 2. Full advantage was taken of the opportunity to exercise control pos...

@Duncan, There is one study by Bill Jurens, "US ordinance between the wars" or something like that. Amongst other things, it covers an exercise specificaly designed to push the battleship crews to the limit, and obtaining the maximum possible rate of fire. In one of the trials, the crew o...

Re: Bismarck against BB-57 South Dakota

- dispersion for full salvo at 18km: 190 meters What kind of dispersion is it? Is it pattern size of full salvo? Then at least american Bureau of ordnance disagreed with it. Typical 16/45 nine-gun patterns was listed as 1.9% of range, i.e. ~340 meters at 18km. You're right about that. The average s...

Re: Bismarck against BB-57 South Dakota

British 16" gun, turret and shells had very bad real life performance. The values for armor penetration of the British shell are imaginary ones. Comparing them to the US L45/L50 firing the 2700pds shell is not a good idea. They were in [completely] different leagues. Perhaps you could provide ...

Re: Bismarck Equipped with ME 109 Fighters ?

launched Me109 pilot was really committing suicide, since the chances of rescue were virtually non-existent. Interesting point - could the 109 have reached France as a one way journey? Assuming it is launched on full tank of fuel..... The Me109 had a very short range, and even assuming no combat an...

Re: Bismarck against BB-57 South Dakota

I understand what you're positing; in fact, that's why I raised the issue myself. But I took the MVs selected by Campbell as representative of the Br and US guns as well as the MV as selected by the USN for their official range table. Hence my taking 2,525 ft/sec and 2,300 ft/sec respectively for r...

Re: Bismarck Equipped with ME 109 Fighters ?

Victorious' attack on Bismarck consisted of nine Swordfish and two Fulmars. The Fulmars were tasked with observing the strike and shadowing the Bismarck. In the event both had to ditch due to lack of fuel as the Victorious' beacon broke down and the Fulmars were having to try and locate the Victori...

Re: Three shafts versus four

4-shaft designs were just as prone to debilitating stern damage as 3-shaft ones. 2 examples: 1 - Prince of Wales hit by 1 torpedo/tragic consequences 2 . Cheers, Alex PoW was hit by two torpedoes in the stern. 3 of her 4 shafts were damaged, and the rudder lost power, but was undamaged. If the floo...
