The weakest version of the torpedo is the Cluster torpedo. Fired from Hiigaran Torpedo Frigates as a single torpedo, it splits into 4 fast torpedoes designed to destroy corvettes or other agile but heavily armored units. In the early stage of the Vaygr War Cluster torpedoes were used against capital ships or even super-capitals as they were only weapon Torpedo Frigates are able to fire. Later on, however, Hiigarans developed standard torpedoes which were found to be greatly effective against enemy frigates.
The heaviest version of Hiigaran torpedoes are the Long-range torpedo fired from the nose-tubes of Destroyers. This version was about 10% slower, had identical range as the standard version, however it had a sightly larger explosive charge allowing it to deal twice as much damage as it's frigate variant. This made it a great weapon against enemy capital ships which weren't capable to run away from the powerful missile.
