[ ] 0: Large Saucer (380,000 Tons)
These ships need to be able to take everything the fucking unknown throws at them. Having a lot of space means a lot of redundancies which means that when Decks 1-4 are flooded with Snargulan Beetles and decks 7-10 are overrun by evil robots, decks 5 and 6 will still contain enough facilities to enact Trekky Babble with.
[ ] 1: Electro-Ceramic Hull Composite (-20% Mass) [Experimental] (Two Success Checks: Cost/Defense)
I'm actually in favour of just using an experimental design because a 20% mass saving is so preposterously huge and hey, worst case it ends up working out to being Ditanium tier while best case, it's on par with tritanium.
