Ark Royal , photographed in 1975 during a eight nation NATO maritime exercise OCEAN SAFARI, in the Eastern Atlantic and Norwegian Sea. On deck can be seen US Navy A7 Corsair and F4 Phantom along with RN Buccaneers and Phantoms.
The USN aircraft were embarked during cross deck operations with the US
In fact there is very little difference in the size of the actual landing strip down the deck. Its all the other parkland that makes it seem so much bigger on US carriers. Somewhere in the gallery is a photo of Ark moored beside a US nuke and its surprising when you compare the landing area, how little difference there is.
