Hope you don't mind me doing a cut and paste of why it may not get 25Kn,
(I don't think it will get anywhere near it, you cant fit 77500 shp IMO)
The ??? area could hold boilers but doesn't have funnels and I think your TR is to small, would it be better to cut out one of the centre turrets and rejig the funnels ?
also 15 inch of belt armour and women in 1915 ?
