National carrier weapon fits reflect aircraft and readiness choices

The lightly armed Queen Elizabeth class contrasts with the heavier gun and missile fit aboard Italy's Trieste and the missile batteries of Charles de Gaulle. Trieste is primarily a helicopter and amphibious operations ship with an F-35B capability, so it can place some weapons where debris poses less danger to its main flying activity. Guns offer comparatively straightforward maintenance and a heavy close-range volume of fire. The balance depends on the aircraft, deck arrangement, and infrastructure available to sustain the weapons. Effective protection reduces the chance of damage forcing the ship out of operations for repair. Thorough peacetime maintenance also gives crews more scope to push equipment during a conflict, while deferred repairs leave less margin when the ship is urgently needed.
