Tangentially related, but do you think the SA Navy will want us to design a Dreadnought for them once the revised treaty is out or are they likely to want to keep pushing LLPs to cover more ground, hunt pirates and get a crop of personnel trained up as spacers before doing more expansion?
I'm wondering if setting up some sort of naval depot stations in the colony regions to act both as logistics and maintenance hubs, personnel transfer points and communications nodes (QEC might fit on a Dreadnought but it may be more useful to fit them on planets and stations first to help with patrols and coordination). Maybe a dry dock slip that can make repairs on an LLP in pressurized atmosphere go easier?
Post-war predictions regarding the Alliance is basically impossible at this point because so much depends upon how that plays out.
The Systems Alliance is in many ways a deeply xenophobic nation (See: Cerberus & Terra Firma) but it also has good reason to be so. The first encounter with alien life was when they destroyed a human starship and conducted a brutal military conquest of one of our colonies with the clear intent to render us into a vassal state. Anyone with any vague understanding of history knows how terrible that would have been for humanity. Fortunately we successfully repelled them, although only
after the colony had been forced into surrender, at which point we were saved from all out war, which we'd have likely lost, by the Citadel Council intervening.
Right away this establishes us as almost being
enslaved as a species by one of the
leading nations of Citadel Space. This is immediately followed up by tensions with the Batarian Hegemony a race of
slavers who protest our expansion into what they perceive as "their territory" and begin preying upon humanity. Raiding our colonies and enslaving our people.
In short humanity's history with intersellar relations basically boil down to "everyone out there wants to enslave us!!!". Hence why the constant massive military expansion going on ever since the First Contact War; a perceived need to defend ourselves against outside threats. Except now things are changing.
If this war goes well for us the Alliance will have defeated their number one threat (the Hegemony), proven their military capabilities against an ancient space-faring civilization (their first contact was back in the days of the
Roman Republic), and earned the respect of the Turians they are fighting alongside. That should serve to significantly counteract the sense of fear towards the outside that has driven a lot of the Alliance's military build up and general actions over the last few decades. If we get a seat on the Council well that will only further increase the effect.
Alternately if the war doesn't go well and turns into a grueling slog well it will only reinforce the idea that the Alliance
isn't safe and we need to not only rebuild but do so bigger and better. Similarly that seat on the Council could provoke more military spending to try and bring the Alliance up to the standard of the other Council Races.
In short it is really too early to tell.
As for navel depots; in a way we've already established those. If you look at the Galaxy Map on the front page we basically already have the core of Alliance territory covered with our existing facilities. We've got the Petra Nebula (Elysium), Arcturus Stream (Benning), Local Cluster (Demeter), and Exodus Cluster (Eden Prime and Terra Nova). We've also got the Citadel Space fallback position covered by Bekenstein's position within the Serpent Nebula. Soon we'll have the Horse Head Nebula with our future base on Amaranthine.
Interestingly Mindoir's location is
hilariously far away from everything else we've invested in. While we don't have a canonical system we do know it is in the "Attican Traverse". If I had to pick I'd say it is in the Shadow Sea Cluster (same as Horizon) since there is a regular shuttle route to Ilium and Shadow Sea is the closest Cluster to the Crescent Nebula (where Illium is) occupied by humanity; just two Relays (Shadow Sea -> Omega Nebula -> Crescent Nebula) away. The fact it is directly connected to Omega makes it being the target of a Batarian slaving raid so easy and believable.
What would we need to do to improve our relations with them further? I get the feeling we're more or less in the same political camp and 'get more jobs and investment' seems a reasonable course of action but I doubt it'll be as simple as "throw thirty billion credits at the problem and get another +2", what do the various worlds need or want to see?
Honestly I've got no idea. The only major human extra-solar colony we don't have a presence on is Trident and on all the colonies we have facilities we've done our best to increase their safety and security as well as (presumably) bringing plenty of credits, and possibility even jobs, into the economy. Maybe helping them expand and exporting new colonists from Earth? Establishing cheaper travel and shipping with a large fleet of starliners?
How well served are other polities for shipbuilding? Do the various Terminus worlds need more ships than they have? I don't believe they're all pirate states, and I can imagine there's some call for some sort of armed merchantman traffic between them due to the risk of piracy. I know there's a boom on exploration and colonization due to being able to lego some hab units together and add an engine for cheap and the construction of cheap base buildings, but what about reducing the cost of civilian ships? Heck, what about building Eezo production facilities so the most expensive and inelastic cost becomes a lot cheaper all of a sudden?
Also, how likely are the politicians to want to throttle naval expansion now that the war is won and they obviously don't need any more ships? Is there anything we could do to help fund the expansion of the navy in peacetime (beyond 'pay taxes' and 'build the ships')?
The Terminus Systems are all pirate states in a sense. They are all nations that
reject the laws of Citadel Space. They, for one reason or another, are places that have decided the laws under which the Citadel governs most of known space are unacceptable to them. This of course makes any form of trade with them difficult as they are all, in a sense, criminals under Council law and I'd be shocked if they weren't under various sanctions and embargoes as a result. This is of course before getting into the fact that the Terminus worlds are heavily backing the Batarian Hegemony, as they are the sole major power friendly to the Terminus, in the current war so in a way they are also enemies of the Systems Alliance.
Eezo production may or may not actually help that much when it comes to Starship costs for Paragon Industries. Our ships are already significantly cheaper then normal because we can use lower purity Eezo in our cores due to improved FTL designs. The biggest expense in our ships is actually down to the Kinetic Barriers. On the LLP for example the Warp Barriers represent 7.8 billion of the 18.2 billion construction cost and 24,414 of the 56,915 of the Production cost or ~40% the credits and Production of the unit goes into its Kinetic Barriers. Figuring out how to lower the resources there is the next big drive towards lower starship prices.
As for how well everyone else is served when it comes to shipbuilding; I have to assume they have most of what they need considering every other major player has been around for
centuries longer then humanity has been on the scene. That said we do have some game changer technology here that
in theory could change things but in practice probably won't.
The first is of course one of our oldest pieces of tech; the humble Repulsor. It literally
triples the range of starships by increasing the ship's speed. Before the best a ship could do was 31.3LY before needing to discharge but that required boosting your engine thrust with anti-matter a limited consumable; without that you were down to just 20.8LY. A Repulsor equipped ship meanwhile can go 62.5LY between discharges with no fuel usage (besides power). This significantly increases the range of starships, makes more distant colonies viable, and improves travel times due to straighter paths. It is also a restricted technology limited to just the Systems Alliance Navy and Paragon Industries subsidiaries.
The second is Multi-Core FTL drives. While this doesn't come with the speed boost it instead comes with
unlimited range. Want to travel from Earth to Noveria without using the Relays?
Now you can. Sure at 10LY/day (best that can be done without Repulsors or anti-matter) it will be a long trip taking nearly four years to cover the 1,375LY to the Horsehead Nebula but it can be done. This opens up massive chunks of galaxy that were previously difficult to reach (no good locations to discharge) or just too long (when you add in discharge time) to be worth traveling to. It also isn't restricted
yet. It almost certainly will be though when we reveal it given the massive strategic implications.
