Corsair

The Yrillian Corsair is essentially an armed freighter, not a combat starship, and as a fighting craft is considered roughly as capable as the Licori Spiny Mouse. They are suitable for engaging civilian shipping but are badly outmatched by any fighting frigate or any ship of cruiserweight or above. In their sole major combat action in Federation records, they launched torpedoes at maximum range against a ship that was crippled and could not evade, then fled at their maximum warp to avoid pursuit. Quick thinking by an escorting Excelsior interposing itself in front of the torpedo salvo was enough to frustrate the attack.
