Hentai kuubou isn't fleet carrier, I guess the translator mistook it for kantai which is fleet. In this case hentai is probably referring to the fact that Saratoga is a battlecrusier modified into a carrier and so carries fairly large guns that carriers usually don't have (hentai means change/modification).
Eh!? You don't need one!?But fleet carriers are pretty useful...... still don't need one?
Okay... I see...Don't you need a splendid carrier, Commander?
I've got excellent guns, and you can get me now for just 120 yen...
