To be honest, that would be rather underwhelming. The ERLLs would be the biggest dissapointment as they are still among the most inefficient weapons ever. Actually I expect some Clan-tech in there, given the advances Defiance has made in the past (XTRO Steiner) concerning XL engines, given the reconquest of Pandora (though I still guess TPTB come up with something like "in the process of capturing the planet the Jade Falcons had more than enough time to self-destruct Red Devil Industries as well as the Quikscell plant because they were smart enough to realize they would not be able to reconquer Pandora") and the general availability due to the Sea Foxes activities.
But to be honest (again), the thing doesn't really strike me as 80 tons heavy. Maybe 60 or 65.
