What on Earth was the rationale for giving the QE class carriers two
islands? Apart from looking ridiculous, surely there must be wind eddies
created between the two.
Now, now, you’re being a bit extreme aren’t you? :-)
She doesn’t look ridiculous, she looks beautiful!
The issue is, you’re conditioned to the look of traditional American
designs, but us Brits do things differently. If you want my opinion, the
US carriers have their islands so far back they look like obese blokes
lying on a sofa…
Well I’m probably being a bit critical - or maybe very critical - I
actually do like the USN and the USA in general! :-)
Do you see the look of purpose in her eyes?
The fact is, the ships have very functional reasons for their designs -
The Ford’s was to put the islands in a more convenient position for
aircraft handling, and the Queen Elizabeth’s reasons were as follows:
The locations of the engines
This was predominant reason. The carriers have two powerful Gas Turbines
to power the ship, and these need to be spaced out as much as possible
to provide better redundancy - if a missile hits the ship, it should not
take out both the power plants. Now, spread out engines make spread out
exhaust stacks, and the traditional method to cater for this is by
having a long, thin island. However the ingenious British engineers
thought outside the box and decided that having twin islands gave more
deck space and actually reduced wind disruption over the deck.
They then capitalised on the idea by enabling the following advantages:
Ideal Bridge and Flyco placements
A carrier has two predominant management structures - the command of the
ship, and the command of the air wing. The two are each given their own
island on the QE Class, with the Bridge enjoying a good view of the bow
for littoral manoeuvring and the Flyco getting a central position to
enable them to see everything on the flight deck clearly.
The two islands allow for much greater redundancy than what is possible
with a single island. They each hold systems capable of doing the job of
the other, allowing the ship to stay completely operational even if the
enemy makes a successful first hit. Also, sensor systems are distributed
between the islands for this reason, too.

The dual islands allows the two powerful radars to be distant from one
another, reducing interference between one another and creating a
clearer picture of the surrounding airspace.
Accommodation for aircraft refuelling and rearming ‘pit stops’
At the front of the base of each island is a covered weapons elevator
and in front of each island is an area dedicated to operations for the
aircraft refuelling and rearming. Each island serves as a hub for the
two pit stops.
I hope this helps, and for reading this far I’ll throw in another cool
photo as a bonus!
