> The Goliath Cannon (assuming you're referring to the Curtiss-Wright J2 Fury and, more specifically, its large guns)

My guess is he's referring to the Goliath Cannon described in sectons 10 and 11 of the backstory:

Over the next few days, weeks, months, and years, the area around Aeron's Icefield was heavily fortified. Large asteroids were brought through the wormhole to act as bases for defensive batteries. A hundred years later, the three Goliath Cannon (Alecto, Megaera and Tisiphone) were constructed and lent their considerable presence to the defense of the region.

. . .

After nearly a hundred years of complete silence on the Serco-Itani border, the Serco begin what was apparently a small offensive. Forty capital ships jump into the Itani buffer sector. The three ladies, the Goliath Cannon, roar to life for their first combat use since their construction. Spitting their particular form of death, a fifty meter long condensed cloud of excited antimatter particles surrounding a phased singularity, the passage of their "shells" visibly ripples any light (as well as, arguably, space and time). Massive swathes are cut in the enemy fleet with every shot. Within approximately two minutes, the Serco have been reduced to five ships. Another twenty ships jump in, only to immediately jump back out again, once the state of their comrades becomes apparent. At a total of seven minutes, thirty one seconds from start to finish, the incident is recorded as the Seven Minute Battle.

Ah, those Goliath Cannons...
yeah, like them.

Yes, you're right Beo, I was referring to the Goliath cannons from the backstory. I forgot their names, tho.

But yeah, those other Goliath cannons are kewl also!

Let's craft up some of these babies. Screw capships. I wanna man the Goliath cannon pointed at the Geira WH. Hee heee. *BLAM*
