Iron Duke is essentially an Orion on steroids, with better overall performance and the addition of a rapid reload consumable. She is a strong battleship for her tier, well equipped to deal with her contemporaries. 

FIREPOWER

Iron Duke's guns are largely the same as Orion, but with improved dispersion and modest buffs to other stats. They are the same good HE slinging, destroyer deleting weapons from before, courtesy of their very flat shell arcs. The addition of rapid reload 1 is nice for modest increases in DPM when necessary, but the guns themselves are already more than good enough.

Iron Duke also has a battery of large caliber 152mm secondaries. These are too short ranged and have too long a reload to be valuable. 

PROTECTION

Iron Duke is on the more fragile end of T5, but quite acceptable. As a T5 battleship, she has modest resistance values but armour and HP that is sufficient for the tier. Basic self preservation will be sufficient to keep yourself alive. 

EVASION

A standard T5 rating here. Iron Duke's speed and agility is very average for this tier, though there are now some fast battleships in her matchmaking spread. Iron Duke, evasion-wise, is perfectly adequate but nothing more. 

ANTI-AIR

Iron Duke lacks the AA damage or range to be a viable threat to CVs. 

Iron Duke was one of the defining classes of super-dreadnought during the first world war. In-game, she is modelled with a fictional refit which adds AA guns and trunks her two funnels into one oversize funnel. This refit has no impact on gameplay and exists purely to make the ship model inaccurate.
