What's the difference between corvettes and frigates?

[Dennemi³]

Frigates just seem a little stronger, is there anything more to it?

[Elitewrecker PT]

Mainly the weapons they can have.

[gn_fighter]

Frigates have torpedos. Corvettes don't. Frigates also have by far less evasion-chance, meaning that they will die a lot more.

Except of course you play with mod's. in that case.. dunno.

[ShandoKhan]

They seperated the torpedo modul from corvettes and created the Frigate ships as full torpedo boats.

Fregates are kind of the uboots of stellaris:
You get them a cloak devise, use torpedos, fly up to an enemy station or fleet with big ships, decloak and they will do huge dmg only to then emergency retreat.

Dont expect them to defeat fleets without cloak in 1 vs1, as torpedos have their reach changed and are now a close combat weapon.
