The Kadeshi aren't going to join. That number ticks upwards for tracking purposes only. Basically imagine they have a N/A tag.
So okay after ruining the humor here I think we kind of have to build a stationary Argus Telescope before we can think about building a mobile one, no?
That reminds me, someone made a post mentioning that so far, none of our starbases have responded to any events despite their high D stats. Now obviously, starbases aren't supposed to do that, but I got to thinking: What's the difference between a starbase and a starship? Starbases don't have warp engines, (and only relatively small sublight engines for manuvering,) so they don't need to constrain for size. Starbases probably use their massive size to gretly reduce the need for our limited SR and BR, instead getting their stats from just making really big components.
So... what if we wanted to make a Starbase have warp capability anyways? What if we changed the design just enough to let a Starbase transport itself at a servicable speed? It'll never be fast enough to respond to emergency situations, but it could manage pre-planned missions. Predicted stellar phenomina that could use oversized sensor arrays, sceduled diplomatic and trade events, research that could use massive tractor beams and deflector dishes, debris fields that a runabout squadron could investigate... And yes, slowly relocating in the event of conflict.
I don't know if it would be considered outdated or anything, but over in the Starbase Design research tree, there's a tech for Starbase lls, which cost 100 sr yet have stats of "C16 S12 H24 L24 P12 D10". Yes, those are ridiculous stats, but it's mostly a combat monster. A stationary combat monster that will very rarely use its S12 or P12, and for that matter rarely see combat. Sure, we still need these kinds of starbases, but developing and building bigger and bigger starbases seems a bit of a waste. An alternate design that slimmed down combat components just enough to fit an effective D1 of warp and sublight capability would be absolutely worth it in a next generation starbase.
Unfortunately, we can't call them "explorer-class starbases". They, uh, won't really be doing much actual exploring.
But they will in spirit!
