I hate to admit it but the shivans got it almost perfect with the Lilith. I mean that ship could threaten even a destroyer .
I've seen ppl here talking about costs of a powerfull H/K warship. The name in itself implies that it is expensive. This ship is designed to take on enemy warship regardless of its class and win.
Of course depending on the actual size of such a ship and its capabilaties different tactic would have to be used.
For example if we are refering to something along the lines of a cruiser or slightly larger wolf pack tactics need to be employed. Grouping several of them toghether so as to be able to take on even a Sath if needed. Of course you would need to group up to 2 wings of such ships in order to make fast short work of a Sath but pretty much everithing else would not need more then 1 wing.
Now if we are talking about something along the size of a Iceni things change a bit as such a ship would be able to mount even more firepower then the said frigate class. And it would be even more advanced as it needs to be self sufficinet for fairly long periods of time and even house 2 or 3 wings of ships .
Such a ship would be very expensive if you include powerfull sensors electronic warfare tech and some stealth features to it. This coupled with the more advanced subspace drives would mean that such a ship would be as powerfull if not more powerfull , in various situations and conditions , then a full blown destroyer. Also it would cost just as much i suppose. However one must look at the bigger picture before throwing such an expensive ship to the garbage.
The GTVA has failed time and time again when it comes to head on full blown engagements with the shivans.
Why ? Its simple the Shivans have more ships and with more powerfull beams. even if they did not have more ships the more powerfull weapons means that by the time a ship manages to react to an incoming shivan warship it is already too late. So why not invest in a ship that can take the battle to the shivans and even win.
Granted it uses hit and run tactics but who cares as long as it gets the job done. even if you loose one such ship for every 3 enemy cap ship destroyed you would still be on top. Just look at how many warships the GTVA lost attempting to take out one shivan destroyer.
Sure you might say well then why not use bombers?
Because bombers can be taken out much fater then a warship and bombs can run out beam can not.
Also you were there to take out the enemy so it doesnt really count now does it
