The Akira drops 8800 torpedo damage on the initial pass, and then has a 3 minute and 40 second reload on those torpedoes.
You're seeing the alpha strike, which is how torpedoes function in SOA2. Higher firing times, good initial damage. We can't create a munitions system without extreme cpu load, so we slow down their cycle rate to balance things out.
As for the Akira balance, in scenario testing, and on stat workups, the Akira is an unexceptional ship. Including bombers, which die rapidly should counters be present, the Akira still has inferior damage output to equivalencies of multiple other ships in the Federation lineup. The ship does have excellent health, but for doing high amounts of damage rapidly, it's far less effective than upgraded Excelsiors, Mirandas, Steamrunners or Intrepids. Unless that alpha strike does all the damage you need.
The Vor'cha is in the same boat. It's an excellent tank of a ship that takes a lot more effort to kill, but it's unexceptional cost wise and slot wise, with many superior ships in the lineup for rapidly killing prime targets. Excellent if you want something you can keep alive, but far inferior to large quantities of B'rels for dumping damage on something.
Quantum torpedoes are a matter of count. The Sovereign has one quantum torpedo launcher, and 9 photon torpedo launchers.
