Fisher's Incomparable versus the ship Britain might have built

How different might the Royal Navy's actual HMS Incomparable have been from Fisher's proposal?

Probably substantially different, with geared turbines, more armour, and a design life suited to long Royal Navy service even if the large guns and speed concept survived.

Too many operational variables prevent a confident prediction that Incomparable would have suffered Hood's fate. Fisher's theoretical ship also differed from the design the Royal Navy would probably approve and build. The service might retain the 20-inch guns and high-speed ambition while replacing diesel machinery with geared steam turbines. Naval constructors would probably add armour and revise the arrangement rather than reproduce the proposal unchanged. Their version would seek a useful life closer to twenty years than Fisher's willingness to accept a ship that might be obsolete after ten.
