Right know even if suddenly have lv 5 buildings, designs etc, we would still lose to IoM because nof sheer numbers.
Our biggest limit is and will be manpower.
Once Imperium or other things found us we must run.
Even if someone like Tau found us, we still must run. Because all the factions in Wh40k will want our knowledge. And use that tech for evil.
We must run run run.
But there is a problem. Our ship needs maintenance and once a century overhauls (if it maintenanced properly) and for that we need heavy industry 3. Which with our current population takes decades to do it. And that is with using max tech 0 or 1 or 3 automation. (Without ai of course. Iron Man War paranoia, so no full automatic factories. Also there could be outside influence on Iro Man. (From Chaos to rogue terrorist to Eldar to Necron to Emperor of Mankind) We may never know).
And it makes sense. In a few decades with max automation you are jumping forward thousands of years of tech. In a sense you are building machines to build machines which will build machines to build machines etc.
The problem with long time is that when we need to escape and found another planet, we wiil need to start from beginning again.
So, we shouldn't leave planet until we founded. And we should use our time fully.
To do what?
To upgrade our ship first.
We need to became self sufficient. We shouldn't have to build everything everytime we came to a new planet. We should be capable of carrying everything with us and not leave anything behind.
NOTE: BUILD SELF DESTRUCT WEAPONS TO YOUR INDUSTRY AND DESTROY EVERYTHING YOU LEAVE BEHIND.
NOTE: THESE SUGGESTIONS ISN'T DESIGNED FOR SPEED. THEY ARE SUGGESTED FOR SAFETY. SO THAT WHEN WE ARE FOUNDED BY OTHERS WE WOULDN'T LOSE.
A- Make your ship as self sufficient as possible.
Self Sufficiency.
1- Food & Leaving space.
Our ship is a freighter. It has dimensions of 1200 x 400 x 400 meters. And it is capable of housing 50000 people. So no problem for a long time from that point.
Our Shipboard Hydroponics Deck will support 15000 people with min food. And we have 2 more food stocked. It is good that we built hothouse. Once our population reached or closes to 15000, we need to built another Shipboard Hydroponics Deck. It Occupies 25 units. Right now we have 63 units of empty cargo space.
2- Fuel
We have 6 fuel. But no means of producing them. We need a Shipboard fuel refinery ASAP. Then if our heavy industry could produce fuel too, once you built Shipboard Heavy Industry, scrap this. But for know it is better to build fuel refinery because we may need it soon. We have only 6 fuel left! What if someone found us.
NOTE: USE CAMO 3 TO HIDE EVERYTHING ASAP
Now, if we managed to came this far, it means we have almost everything ready for an immediate escape. Only we could house 15000 without building an extra. Shipboard Hydroponics Deck. Anyway, we came to two not so immediate things.
Rejuvenant and Heavy Industry for ship overhauls (still 99 years away).
3- Starboard Genetics & Rejuvenat Facility.
Because our cargo space is limited, after we escaped, after our stocks is finished you have only 1 decade until rejuvenant effect is finished. So we will need an Starboard version of this facility.
4- Shipboard Heavy Industry 3
We need this. Because, frankly this most difficult one to build. We couldn't afford to build everytime. And if it can produce fuel, scrap fuel refinery.
Now that these are finished lets lets at cargo status. And how long our ship could survive in space?
We have 200 cargo units.
-Science lv 5 datacore. 1 cargo unit.
-Shipboard Light Industry. 100 units.
-Shipboard Hydroponics Deck. 25 units
-Infantry Equipment (Tech Level 3) - 1 battalion (1000 combatants), maintained by light industry, fills 1 unit cargo space
And 73 cargo space potential.
The problem is that, could our fuel rafinery, rejuvenant or heavy industry fit inside?
NO!
Then what! Should we after finished planetary heavy industry 3 build new ships?
No! Again.
That is wasteful. And our manpower and time is limited.
B- Welcome to Refiting and Modifying Your Ship!
Now, you must understand this. While modifying is fast and cheap. It never as good as a purpose built ship. But we don't have time for designing and building a bigger, better ship.
And our first priority is to add cargo space to your ship.
1- Add cargo space. And adjust everything to new ship dimensions.
2- Build fuel refinery, rejuvenant and heavy industry.
Congratulations! You are almost self sufficient!
Except once the materials in your cargo is finished, you still have to find a planet to mine.
So for doing research( can we do research in ship?, if so skip this).
And once our population reaches 50,000 (which by that time, we would have to build extra Hydroponics Decks. At least 1 per 15,000 people) we need to refit again.
And too much refit is bad.
But you can still build things like lab, astroid miners etc.
But, don't refiit too much.
Now came part 3.
C- Build a better and bigger ship.
Now, your current ships dimensions are 1200m*400m*400m.
And because of Eric's range limitations, it is better to have only one ship for the moment.
Also you don't want to leave anything behind. You want to build everything in your ship.
Your new ship must have everything your civilization needs.
Also your ship must be very modular.
You must have capability of adding or removing new areas without compromising anything.
In these directions, it is better to built block by block, starting with engines block( both warp and non-warp) capable of lifting 25-50 block.
So that when you are forced to leave planet, you don't lose any progress.
Like our current international space station's blocks. Only with better design, tech and defence etc.
Then built living space blocks, weapons blocks, void shield blocks, hydroponics blocks, laboratory blocks, cargo blocks, light industry blocks, mining blocks etc.
Designing modular ships are harder. And modular ships are more expensive. There is a reason military on our Earth is prefers either specialized or non-specialized general tools. Because while modular ones are capable of performing every task like general ones with power of specialized ones, they are expensive.
Except, in a Utopia civilization where every citizen is at least 45% capable in everything so there is no need for extra specialized training to build and use these. Energy and Materials are almost free, and only limit is mining and manpower.
Modular tools, and ships are great for you.
Also build shipyard blocks.
And once you built everything you have in your ex-ship, scrap that and used materials.
And this modular ship has one more speciality. You cpuld built your ship blocks bigger and bigger and scrap small ones.
You can built a ever-becaming- bigger type ship.
Think about it. One day your modular ship becames as big as a Earth size planet. It could house trillions of people, feed and sustain them. Could build every ship type up to moon size ones. Could in a few hours change from a shipyard configuration to mining configuration and siphon matter from stars to feeds itself. It could built ships by millions one hour. Then suddenly scraps shipyard blocks and builds weapon blocks. And it fires every single weapon.
Anyway, my suggested and sorted un-detailed plan:
After you finished building planetary heavy industry 3;
1- modify your ship to add extra cargo space.
2- Design and build shipboard fuel rafinery, rejuvenant, heavy industry 3.
3- Design and build 1 shipboard hydroponics to bring max food supperted people from 15,000 to 30,000.
4- Design & build (if you can) asteroid miners, normal miners, laboratory etc.
5- D&B planetary shipyard.
6- D&B your modular ships first block. Normal & Warp engines first. The stuff your ship has 2nd.
7- When your new ship reaches your old ships capacity, scrap it.
8- Continue building blocks. Decide ratio of produced block types.
Also I suggest building cyborg thing. Maybe we can improve our efficiency. Also think ways of reducing required manpower maintenance. So that we could maintain ore buildings max with our population.
