I am guessing he may not even model the original Dreadnought, she was a minor unit by the time the Great War game along but who knows how much energy our creator has
Weill be interesting to see what may happen by the time this remarkable project launches.
On thinking over the way the capital ships operated in war time conditions some comments came to mind, the firing of the main battery guns was a significant event in both practice and in actual action. It caused tremendous stress on the gun barrels, mechanism and the ship itself. For that reason turret dispostion and reinforcement in terms of ship structure and members was critical to consider, and the cost of setting turrents amid ships for additional fire power also caused great strain on ship structure and limited interior space. By the end of the war design had shifted to fore and aft main batteries for those reasons.
Also the firing of the big guns caussed always damage to the decks, and bulkheads, paint blistered and burned from the muzzle blasts and the wooden decking often took damage as well from ths ships own guns. ...not to speak of damage from enemy fire. It was no small matter to fire the guns, and the barrels has a specific life time which would be affected by wear, and even in normal firing, the wear of the gun bore woudl change the deflection and the angle of fire achieved by each individual gun. So turrent captains were in charge of maintaining their guns quality and accuracy along with the Fire Control Officers and it was a complex and demanding aspect of the Big ships and their batteries. the ammunition itsself often had to be specifically machines for individual types of battery, and type, and the storage of the ammunitoin as you will well know was a critical matter and caused the loss of ships due to magazine fires esp for the Royal Navy at Jutland. Fortunatley for the High Seas Fleet due to an accident involving a magazine fire and flash back the High Seas Fleet has fitted fire proof doors to all their major ship magazines and did not suffer from this hazard.
the Heligoland class German battleships which I believe you have already modelled? was one of the most intensive with four turrets amid ships, they were called the "turtles" by the Fleet and tho it looks ungainly they were good ships and delivered an awesome rate of fire on the broadside.
the key was always to try to cross the enemy fleet's T, which was one of the main goals of a fleet admiial of that era....and coudl have devestating affects as it took high level of training to turn a fleet about, a matter which the High Seas Fleet achieved without mishap at least twice in Jutland and on other occasions.
lots to think of and to remember when it comes to deploying the fleets or squadrons in any missions you design, i will be happy to advise on standard fleet deployment practices of that era.
