That's no excuse in my book. Plus in Argonautica the attacker was a Corvette (albeit with Bomber support). An Orion would have nailed the Moloch in problem, assuming it had proper Fighter support to allow it to concentrate on the Corvette of course. A replacement should always be better than the original. Otherwise, what's the point ?
I honestly don't think that the Hecate was intended to entirely replace the Orion. Sure, the Orion's were getting phased out, simply because most of them were 30+ years old. Still, the GTVA must have found good use for the Orion as an offensive weapon, leaving Hecates to perform a more carrier-suited role, while more and more corvettes were gradually added in as an offensive weapon to take the Orion's place.
Then again, this should be looked at in terms of the GTV
A, as both sides now had combined their forces, and now each side had ships fitted to different roles. The Hatshepsut and the Typhon, IMO, had an opposite relation as the Orion-Hecate. The Typhon seemed to be more of a Vasudan fighter carrier, though it was still a problem to attack. The Hatshepsut, on the other hand, had a spine covered in anti-capital ship beams. I'm supposing that the GTVA had expected to decommission its old Orion and Typhons, and replace Typhons with Hecates and Orions with Hatshepsuts, since they seem to fit the same role as each other.
