not sure the Excal would have unlimited fuel. Remember in WC3 they had to stop at asteroid depots to repair, rearm, and refuel. I would agree that the lance should have unlimited range as it has a micro M/AM reactor in it.
When we used to debate this sort of thing 20 years ago, we'd reference this passage from the Price of Freedom novel. Of course, WC3 doesn't refill the Excalibur's engines like WC4 does the Dragon/Lance.
He pointed up at the large intakes mounted behind the pilot and along the leading edges of the wings. "See those Bussard intakes? They scoop in everything, hydrogen, dust, anything their magnetic fields catch. The matter feeds a whole new power plant—matter/antimatter. Do you know what that means?"
Blair nodded his head. He'd first encountered the antimatter engines on the experimental Excalibur fighters he'd used for the attack on Kilrah that ended the war. Those engines, the first successful attempt at miniaturizing the cap ships' drives, allowed virtually unlimited range.
He peered at the fighter, scrutinizing its lines. Shave here, add there, change the camber of the wing and reposition the intakes. He could see the family resemblance once he knew what to look for. The Excaliburs had been prototypes for the Black Lances.
