'X' and 'Y' Mark II 15-inch turrets of the battlecruiser HMS Hood during construction
Komment:
"Mattzo12
The Mark II turret was unique to HMS Hood and had a distinct look. This has several improvements over the Mark I turret as fitted to the Queen Elizabeth and Revenge classes:
- Nominal cycle time reduced from 36 seconds to 32 seconds (although 30 seconds was achieved in practice with the Mark I).
- Maximum elevation increased from 20 degrees to 30 degrees, which increase maximum gun range with a worn gun and a 4 crh shell from 23,400 yards to 28,500 yards.
- The armour of the front plate was increased from 13in to 15in.
- The armour of the forward part of the side was increased from 11in to 12in.
- Sighting ports moved from roof to turret face, which allowed the superfiring turret to fire directly over the lower turret.
- All four turrets were equipped with 30 ft rangefinders.
- Flash-tighness improved to handing room cordite hoppers and the cordite hoist cage
- Flash door added to the hoist well.
- Adjustable anti-surging stops fitted to shell hoist, which enabled longer shells to be carried.
- Mechnical improvements to the training gear and gun run-out.
Then & Now: In Oslo, steel plates from the German battleship Tirpitz continue to be a part of everyday life, you can walk and drive over them. The city’s Agency for Water and Sewerage Works acquired a substantial amount of steel from Tirpitz. These steel plates are still in use today.
