Re: Feindliche Ortung

The report mentions that typical sound detection range was only 10% of that reported by PE during the Bismarck episode. The mentioned 10% do not characterize the typical range, it was a exceptional bad range area near the Azores, as even the usually difficult Baltic Sea accoustic conditions allow f...

Re: Alaska Class: Battlecruise or Large Cruiser Semi-debate

The PBS hull was rated for 30 knots but could only reach 29.4 knots in ultra light trails. It seems adding bulges cost them a knot off the top speed. The rest was increased displacement from enlarging the superstructure/armaments, to meet the numerous roles demanded. Reportedly mid life plans inclu...

Re: Vanguard and Bismarck

As I understand the main reason allies went to single deck armor plate was to defeat bombs, not shells. https://lh3.googleusercontent.com/6fF6skXBfWXlupw2FzqVIcgSbwqucePzGOiKui5HVEqJEJZV95TqgzH-9L3qMQkCr65sl1l9vYDXojHTZ2ssN2qOdRpWxu1ho2xVFDTP39S9hANKoMgVq6e7YICSQ0HtMksZc3VX-KYZZ-_-viwV6LexscQy1RzqI7...

Re: Vanguard and Bismarck

... face hardened armour... In that area British armour proved to be better
