Yes General Battuta, I know which plan you're talking about. And it failed miserably.
[...]exploiting these weaknesses will require firepower that can be provided only by the main guns of our capital ships. The GVD Psamtik, the GTD Aquitaine, and the GVD Toeris are standing by. Your mission is to lure the Sathanas into position.
The Sathanas disregarded the GTVA and ran straight for the node.
Besides, if the only way to engage a Sathanas the GTVA can think of requires a very specific battlefield (the nebula), and they fail to make sure the enemy will do battle where the Alliance wants them to, that plan is bound to fail.
Then later came this:
"The Sathanas decimated our fleet at the Capella node.[...]"
"This is the Thebes. We have emerged within a large debris field, Command."
A fleet blockading the Capella node was destroyed. The exact size of said fleet is unknown in canon, but judging by the way the Phoenicia was considered absolutely expendable, as well as the presence of a
large debris field, it's reasonable to assume the blockade consisted of several destroyers, and possibly smaller warships too.
Fact: The Sathanas is faster than every destroyer in the Allied fleet.
I've ran simulations where even 4 GTVA destroyers flanking a Sathanas where unable to destroy it before being outrunned and falling out of range. And such a scenario assumes GTVA warships can jump near a Sathanas with enough precision to avoid its devastating frontal and rear beams. I'm not even considering Allied destroyers would have to deal with any warships escorting a Sathanas. Or even a Sathanas wing in formation!
In my humble opinion, this demonstrates destroyers are both cost-ineffective and overall ineffective against a Sathanas.
Long range torpedoes, fast, really really fast, stealth and with enough punch to pierce through the armour of any warship so it can deliver a couple of kilotons worth of explosives into the inner halls of the target.
Untested technology. Besides, nothing in canon indicates such a weapon would be possible with Allied technology. And the Sathanas has AWACS capability.
By the way, has anyone considered my plan? Any opinions?
