They chose two islands to maximize survivability. There is a gas turbine below each of the islands, and above the waterline.Brits claim their two island design has best of the both worlds but so far no one else is going with it.
Source:There are two sets of power propulsion systems (a gas turbine and two diesel engines), located in different areas of the ship separated by watertight doors. This means there are also two exhaust stacks, one forward and one aft, which are masked within the twin islands. Survivability is increased further by the islands being designed with the capability to assume each other’s role in an emergency.”
Yeah, everything about ship building is picking your tradeoffs with the limited space. Britain's decision makes sense given they can't just crank out carrier after carrier like the U.S. or China can if need be. Though it does assume if they aren't able to survive an attack on the first island they'd somehow survive an attack on the second. So it wouldn't be my pick but I can understand why they'd go with it.They chose two islands to maximize survivability. There is a gas turbine below each of the islands, and above the waterline.

This sentence isn't true: "The Queen Elizabeth Class aircraft carriers are the first carriers to incorporate a twin island design, which separates the running of the ship from the flying operations resulting in greater visibility of operations and increases survivability."
South Korea is building a twin island aircraft carrier.Brits claim their two island design has best of the both worlds but so far no one else is going with it.
the Koreans are. [Edit] Oops! I am late but I got a pictureBrits claim their two island design has best of the both worlds but so far no one else is going with it.
There is also the Italian Navy Trieste with 2 islands. It's an LHD, but it carries F35Bsthe Koreans are. [Edit] Oops! I am late but I got a picture
