Engines,
Absolutely, I wasn't trying to black cat you, just putting some other figures up there
Ark also had 3 Merlins and 2 Lynx on board at the time, which was crowded but not unduly so. As I recall Invincible only had a 771 SAR cab on at the time.
That's what you get with a small carrier, you trade off number of jets vs number of helos as required, hopefullly with QE and POW that will be a less arduous task!
BEagle - If you want to see a 'little carrier' I'd suggest the Italians, but they use it to very good effect when required.
