If the drawing does show the carrier in a timeframe that precedes 1940s you have too much AA.
timeframe = last 10-20 years due the technological advancement in aircraft being slowed due to Zeppelins being preferred.
I would also advice either using parts sheet AA guns(suggestively the Pom-pom), or redo them.
And like some have already said: it would be good if you changed the planes so that they come from more similar times of tech.
1) They are of my own design and they are muti-barrelled guns.
2) same can be said for the Swordfish.
