I've been busy with other things for the past few weeks, so development is going pretty slow. (I'm still on the first mission, though I'm almost done.) However, I do have a good enough idea of future missions to post some screenshots (though they might not be entirely accurate) and some pre-campaign quotes and ship descriptions. So, I'll be doing that for then next few months.
This is the GTVA's most powerful warship, the GTD Archon. It's a flagship-not just of a fleet, but of the entire Terran navy. Its four BFBlues outrange and slightly outdamage the Sathanas's BFReds shot-for-shot, but they have a far longer recharge time (in a fair fight, the Sathanas will always win). As the tech description says, it can destroy a capital ship with a single salvo of its primary cannons.
The Archon probably won't appear much in the campaign, since it would insta-kill anything smaller than another superdestroyer.

Tech Description:
The Archon superdestroyer is flagship of the Terran Armada. This incredible warship is armed with sixty-six powerful weapon systems, including four super-heavy beam cannons that can obliterate capital ships in a single salvo. No Alliance warship is more powerful. At present, the Archon may seem unnecessary, but if the Shivans ever return it will be our best hope for survival.
