Looking for roller path/barbette diameter for Mackensen class. I have been searching source after source w/o luck! Turret weight would be helpful as well. Thanks! |

http://www.navweaps.com/Weapons/WNGER_14-45_skc14.php These found with a quick search. This site has info about many naval guns. Try also to search for the gun itself in Google. |

Thanks, but take my word for it, I have done more than "a quick search " Tried Breyer. Tried Conway's. Etc. |

Perhaps German sources have more info. |

I've got quite a few detailed books on battleships be it British or German and none of them give any information on turret diameters. What do you need the information for? |

I am thinking of doing a post war completion of one of the Mackensens by the Dutch. |

Often turret diagrams will have them. |

The best I can do for you is from Friedman's 'Naval Weapons of WW!' pages 131-133 Mackensen 35cm: "The DrLC/1914 mounting was similar to that of the Baden Protection 32cm face 20cm sides, 12cm slopes 21cm rear flat roof 11cm Baden 38cm: A turret Wt 867440kg Roller bearing ring diam 8.75m; internal barbette diam 10.0m gun axes 3.7m apart. You could scale those down in the ratio 35/38 for the calibres. Protection 35cm face, 25cm sides, 29cm rear, roof12cm, slopes 20cm front, 12cm sides. E. Yorck 38cm: 30cm face,25cm sloping face, 15cm roof. You can either assume 'similar to Baden' means same size, or do some estimates based on gun sizes (which are given for both guns in some detail. Both 45 calibre) Treating the turret as a hollow shell, so weights go as the square of lengths (eg gun calibre) is roughly OK if the armour is comparable. (No use using weight of 6in turrets, some with 1in armour, some with 2in!) That would make Mackensen's turret about 735000kg if smaller. but only 676000 with armour thinner in same ratio, as Friedman states. Navweaps will give other turret weights for other ships for comparisons. HMS Canada with 14in guns had turret revolving weight 660 tons. The roller path diameter was the same as the UK 15in MkI 27ft which had a revolving weight of 770tons. The 13.5in had roller path diam 24ft6, weight of turret 590tons EDIT of all ship data, I've found accurate reliable turret and gun mounting data, especially weights, hardest to find. |

In 'German Battlecruisers of World War One' the diagrams and drawings of the turret look like a smaller version of the 380mm turrets of the Bayern class. If that helps. |
