Fighters were used by the Federation in the Dominion war, infact, the designer of the Akira class stated in an interview that it was intended to be a through-deck cruiser (carrier). The Romulans (at least the Remans) showed a move toward fighter tactics in Star Trek Nemisis by outfitting the Scimitar armed with several "Scorpion Class" fighters. That said, though, fighters are not normally characteristic of Star Trek. Star Trek style battles tend to harken back to Roman naval warfare where every shot, ramming, boarding, and manuver counted. This is very different from the Star Wars syle of space battle which simulates air battles with active fighter jets and stagnet carriers.
