Allright, time to make my big argumentpost. First I will try to go through all the options individually and then go through some combos.
-[ ] Military Bay
Converting the open slot to military production offers significant developmental potential due to the ability to do large amounts of manufacturing without the stresses of gravity interfering with the process. While not everything will be aided by such a construction, this will make the OSRCT significantly less dependent on massed fusion launches from ground support facilities.
(Progress 0/450: 20 resources per die)
- Significantly improved OSRCT forces
- Orbital drop Mammoth and Predator
- Focus on conventional manufacturing in orbit.
- Will require importing significant numbers of parts.
- Militarists, Initiative First, Homeland all strongly support.
ORSCT is a powerful and useful tool. However, it is not something I would use one of our Enterprise slots for. We are still in the space-should-be-for-space-expansion-phase and this is something in space to support us on the ground.
-[ ] Advanced Materials Bay
Across a wide selection of fields within materials science, the ability to make objects in microgravity has significant implications, ranging from optics and large-scale crystals, to alloys and composites. While small-scale production as done in such a bay will be of limited overall use, it is likely to heavily inform future projects.
(Progress 0/400: 20 resources per die) (+8 Capital Goods)
- Synergizes with all other bays, but not as well as some other combinations.
- Improves performance of high tech systems.
- Will marginally increase STU consumption. See Jevons Paradox.
- Few strong political opinions.
I will be honest, I don't see the appeal of this. But everyone else seems to go wild over Advanced Materials, so it has to do something right. Many of the things produced in the bay are likely for niche applications that benefit our military, ground industry, infrastructure first and space second. The only saving grace for is the mention that it might benefit getting faster Gdrives.
-[ ] Satellite Bay
Most satellites are very low-density constructions, with much of their bulk composed of materials such as foamed aluminum or layers of foil. By specializing the Enterprise towards building these units, there are significant cost savings due to being able to haul up materials by the ton, rather than having to figure out how to fit them into a launch. Additionally the satellites themselves will be significantly more refined, as they do not need to undergo the difficulties of a chemical or fusion launch.
(Progress 0/400: 20 resources per die) (Discounts Satellites by 20 points)
- Helps probes, ion cannons, laser satellites.
- Can work for sending various small scale orbital assets to other worlds.
- Is built with large scale satellite constellations in mind.
- Supported by the Militarists
Sattelites are not that big of a part of space expansion. Dismissed.
-[ ] Station Bay
The largest limitations on the size of a station are the dimensions of the Leopards and Unions doing the construction. For example, there is significant use of ten meter struts on both stations, rather than longer ones that can take greater loads per kilogram. This in turn means that there are thousands upon thousands of joins, adding hundreds of tons of material that do not need to be there. Building a dedicated bay for building large scale station components will both increase the strength of the stations, and substantially decrease their costs.
(Progress 0/400: 20 resources per die) (-1 Capital Goods) (Discounts stations by 10 points)
- Makes stations cheaper. Is kind of it. Relatively limited synergies.
- Supported by Starbound and Developmentalists
The big one. We will have very big station goals next plan and the ones after that. We already have a 20 point discount on stations, can get another 5 from Leo IIs and 10 from this, for a total of 45, or a relative amount of 18.75% compared to our existing discounts. Over the all phases for Columbia/Shala the extra 10 points add up to 10+20+40+80+160=310 progress points per station, or roughly 4 orbital dice, saved. This means faster progress, it means more can be done with less dice. As much as I don't like this one because it takes away from my personal favourite, it is too good to pass up.
-[ ] Gravitic Shipyard
With the exception of GDIS Pathfinder, GDI cannot effectively reach beyond the Moon in a reasonable amount of time. While the throughput of a fusion craft is higher within that boundary, attempts to exploit Martian and Belt resources – let alone materials beyond the Belt – require the construction and maintenance of dozens of gravitic drive ships capable of long range transits. While still too limited in acceleration to move people and materials off earth, the same problem certainly does not apply to many of the other areas of interest in the solar system.
(Progress 0/450: 30 resources per die) (-2 STU, -1 Capital Goods)
- Focus on long range exploration
- Ships are very fast over long distances, more limited over short ones. Pretty much anything that requires multiple significant transfers is going to be faster.
- Currently manage half a gravity of acceleration, likely future redesigns to get more acceleration.
- Starbound and Militarist interests.
Some might say I am biased. But we need to take this. People might try to argue that fusion is in some way better in something, and they might be right right now, but wrong medium to long term. The truth is the Gdrive is a gamechanger in terms of propulsion that flips the game of space travel. No need to carry reaction mass as propellant or worry about ship weight. A Gdrive ship can be as heavy as it wants it will go anywhere at the same absurd speed. No need to worry about required deltaV to get anywhere. You might be able to go faster than the Gdrive with conventional rocketry short term, but that's it, short term. Even at the best theoretical conditions a 0.5g fusion engine burns through hydrogen fuel too fast, not to speak of anything heavier like oxygen or nitrogen. If you take out the extra weight and volume requirements for the enormeous engines and fuel tanks a conventional spacecraft needs to match little pathfinder even for a shirt while, you probably end up with more cargo space on pathfinder itself. The faster we get the damn things beyond 1g+ acceleration, the sooner we can use them to just straight take off and land on earth to make use of their physics cheating magic to lift anything that fits into their cargo bays straight into orbit at effectively zero cost.
-[ ] Fusion Shipyard
Currently, all GDI fusion craft are designed with the ability to climb out of the Earth's gravity well as a core function. However, with the Moon and beyond as goals of GDI's space program, the need for substantial numbers of heavy transit vessels is critical. Large fusion tenders, either in short-legged manned, or long-legged unmanned designs, can serve to fill key niches as part of a set of transport solutions across the solar system.
(Progress 0/500: 20 resources per die)
- I like big ships and I cannot lie.
- Container ships in space.
- Mostly orbiter only designs
- Best for Lunar operations.
- Can do Mars.
- Transmartian operations become increasingly difficult.
- Developmentalist core interest.
I will give Fusion some points. As it stands now it has the advantage of simplifying mass transport between Luna and Earth, in terms of STU cost. There is a hidden cost named fuel that seems to not be talked about but whatever. Gdrive travel between Earth and Luna is still faster and in terms of Mars travels, one of the fusion trawlers would need to be worth around 36.5 Gdrive ships or be outperformed.
Combos:
Personally I see three combos being worth discussing.
Maximum Space Expansion
-Station
-Gdrive
-Fusion
I will be honest, I like this. The loss of somewhat admat is regrettable, but it leaves us with the best of both world shipwise and should give us a pretty big advantage in terms of future station, lunar and ship construction, all good things for space.
Maximum Space Industry
-Admat
-Gdrive
-Fusion
The Station bay does not save us this much in the immediate run and a focus on advmat still leaves us with maximum shipyard, earth-luna shipment and flexibility in terms of the rest of the solar system.
Mixed Industry
-Admat
-Station
-Gdrive/Fusion
I guess this is what it will come down to in the end, a knife fight between fusion and Gdrives. And I know which side I am on. This but with Gdrives gives up space infra + speed gdrives + you get your goddamn low-g manufactured Crystals. Everyone is happy.
So my money is on []Gravitic Shipyard
