ArdRaeiss: Реддит: "Well, can't unsee that now. At least it is a plausible upgrade, the removal of the second funnel. But still..."   EU форум: "Gonna stick my neck out and say, well done on the refit modelling. We know you need to throw modern AA and fire control on them and they do look a bit randomly "tacked on", but the fact these are small details and the overall original look is preserved (especially for Orion) shows you listened to the feedback on German BBs. Thank you and good job!" "Iron Duke looks moderately refit with a single trunked funnel and some AA placements. However WG seems to have refrained from slapping on absurd bow refits as see elsewhere. So I am happy about the Duke as well." "Well yes. Iron Duke is a #FakeShip obviously. But they applied a Revenge Class Style refit as the Iron Dukes never got any refits and kept the fantasy stuff limited. Some minor refits are ok as long as they are plausible and fall under artistic license. That is in contrast to the bullshice they did on the DE BBs which is implausible, poorly executed and looks like complete garbage." "The Use of Coal mandates two funnels in an 18 boiler arrangement due to the greater amount of smoke generated by burning. 
a theoretical late 1920's refit of the Iron dukes to convert them to oil fired boilers rather than coal fired would use the boilers of the Nelson class in terms of age and design which means they would have been able to cut down the 18 boilers to 8 and gain some 11,000 shp and would have been pushing 23.5kts 
but more importantly it would have been feasible to install a new single funnel as on the Nelson and Revenge Classes. 

so the design of a single funnel iron duke is completely feasible."
