I've been thinking about how the vessels would be best balanced and I realized that examples from Starlancer would be perfect for determining the best balances, because lets face it, Freelancer was made as "Go anywhere and shoot anything all on your own because you are an invulnerable hero" and Starlancer was more of a "Your the best fighter pilot in the fleet that can take on entire fighter wings, but you cant win the war by yourself."
Fighters: Small, fast and agile. Good at engaging other fighters/bombers and other small craft including freighters and gunboats. They can soften up large capital ships by knocking stuff of of the surface but cant destroy the ship without support. Relies on its manuverablity to survive encounters with larger ships.
Bombers: Slow, not very maneuverable and will drop like flies to fighters or gunboats, but they can destroy capital ships easily with on good torpedo salvo. Relies heavily on fighters and stealth for protection.
Gunboats: Reasonably fas and agile, packs enough firepower to rip apart fighters and bombers with only a few hits. Lacks the firepower or armour to take on larger capships.
Capital ships: Very slow and handles like a brick. Packs very heavy firepower and heavy armour but is extremely vulnerable to enemy torpedoes. Relies heavily on support ships to eliminate fighters and bombers.
