Hi. I'm brand new to the game, been learning for a week, now I think I'm ready to turn off SM and play for real! Any advice that could save me from a shattering calamity, too early, greatly appreciated!
This is a standard game, spent RP myself with 6000 left over. This is my starting fleet that I'd like you to evaluate, along with my general strategy to expand as early as possible, albeit slowly.

Underground Infrastructure is coming once a suitable scientist appears. I'm aiming to set up a chain of colonies providing fuel production, sensors, maintainance and re-arming facilites on planets and strategic chunks that would be otherwise uninhabitable.
The Construction ship will always be tasked with a Freighter, which will provide sensors coverage. Operating as a combined unit with a range of 13. 8 billion km, this pair will hop backwards and forwards with Construction Battalions and cargo. I'm guessing carrying raw materials, as opposed to infrastructure, would be the way to go. Later, a Cryogenic Ship will replace the freighter in the task group, with the Construction Ship moving ground forces or Construction Brigades along the chain.
Fuel is going to be an issue. All the task groups will be moving fuel along the chain, retaining the minimum to return to a fuel-producing colony. Hopefully this will ease enough juice through the system that I can belay producing Tankers until Sorium Harvester is researched, eventually.
There is missile tech, and a sensor array as described on the wiki, although no actual missiles or FC as yet. This is the military:

Does my plan have a chance?
Commercial ships' sensors superfluous? (Try saying that ten times in thirty seconds, it ought to be possible but isn't. Another mystery of the universe)
All your wisdom gratefully received.
-
Superfluous but not completely useless, though the cost of adding sensors to everything does add up over time. And while your plan woul;d work it is always much easier to just dump regular infrastructure onto suitable planets since you don't need construction brigades to build them.
-
I was planning to have Earth producing Automated Mines in the initial stages. When shipping lines have developed there will be a healthy stock of them ready to go. At that point I'm expecting to be able to arrive at colonies with all the raw materials for infrastructure in place.
I imagine there's a limit on the number of CBs that can be used in place of Construction Factories, just seems to me it's a more economic way of moving the frontier forward, given the fuel situation. I mean, wouldn't the raw materials be considerably less of a burden than finished infrastructure?
Also, am I right in thinking that Underground Infrastructure can only be produced in this way?
If having sensors on commercials is worthwhile I could move one over to the Construction Ship so there would be more control over EM output. Is that worth doing, and if so, which one?
-
I think your transport is too small to transport CB.
edit: Yup CB is size 25 and battalion size transport can only transport units of size 5 that is size of various combat battalions.
-
Ah! Good save!
That knocks everything commercial up to around the 33,000 tonne mark but I think it's do-able. Probably better in fact. Could use up my final bit of RP on better engines.
-
Geological survey sensors and gravitational survey sensors are affected by crew morale. Crew morale will suffer once a ship exceeds it's intended deployment time. Your survey ships have an intended deployment time of 3 months each, which isn't long enough to be all that productive. On board maintenance operations are also affected by crew morale, so they won't achieve their stated maintenance life either.
I recommend upping intended maintenance life to 36 months or so, and maybe adding some more fuel; 18 billion km seems like a long distance, but you might burn through that sooner than you think on a surveyor. I find that fuel is the most limiting factor for my early game survey efforts, especially once I start surveying beyond my home system.
-
I agree about the fuel and deployment time. My survey ships usually have deployment time of 24 months. I would increase number of fuel tanks on your cargo and colony ships as well.
-
Make sure that your explorers use Tiny Fuel Storage instead of larger, as well. It improves maint life AND combat survivability.
In my opinion Commercial engines should be 50hs every time, it helps fuel efficiency a LOT.
Active sensors on most of your freighters is pointless. Stick a thermal or EM on them and walk away.
---
I would suggest building a Navy Yard and keeping a running update on a missile based design, but not building it until needed.
Hit Chances with missiles is heavily influenced by speed. It is usually better to use a bigger engine than to add agility.
Try to use the estimator at http://aurora2.pentarch.org/index.php/topic,5855.msg60061.html#msg60061
I can only figure out the missile estimator myself, but it works very well.
-
I would ditch the sensors on the freighter and just build a specialized sensor ship to do that job instead, letting the freighters stick to their main role of handling freight. You can design something about the size of one of your surveyors that will be cheaper, faster, quicker to build, and much more versatile than a freighter.
I also have to agree with the point about your surveyors; they're much too short-ranged and that'll hamstring you pretty badly as you expand, especially if you're trying to expand as quickly as possible. Your other ships could use more fuel too, but it's not nearly as essential. When I designed my surveyors for my current game my goal was for them to be able to operate for at least a year at full power without needing an overhaul or refueling. You'll need that once you get outside your home system.
Might not be a bad idea to design and build a few small warships right away, either in game or using the instant OB feature. If you run into anything unfriendly with guns on it close to your home system, you're gonna be pretty screwed if all you have is commercial ships. Even if you just lose a surveyor or a construction ship, that's more than you want to lose in the early game if you don't have to. FACs with box launchers are cheap, quick to build, and enough of them put together can put out a salvo of missiles that will make even a capital ship sit up and take notice.

Thanks for the response. I took on board the advice and started afresh.
Twenty months in and the Galactic Empire fleet comprises twelve vessels, with two more currently in production. The fleet is currently split 50-50 between military and commercial.
Of the military, there are four geosurvey ships, two of which recently entered service. There are also two gravsurvey ships, one of which surveyed a whole system in a year. . . finding nothing. They follow this pattern:

Exploration has so far turned up faily disappointing results. Hoping to strike it lucky with searches of the remaining two Sol jump points.
Commercial fleet consists of four freighters and two cyro ships. Unfortunately the cryo ships have been relatively redundant so far, with only Venus coming up for minerals amongst the central planets.

The cryo ships are practically identical with 100,000 berths.
There are two Jump Freighters under production, looking like this:

These should be ready in six months time, so should be seeing boots on the ground in another system in a year or so.
There's no real spare capacity for further additions at this stage, due to the scarcity of Duranium. As far as developments for the armed contingency go - sensor array for attack ships is being researched, missiles and fire control have yet to follow. Will probably be a further three years before armed vessels are avaiable, so the Empire may have a quite short history.

Don't get too discouraged by dead ends in your jump network. If the luck of the dice is against you, then you can fix it in spacemaster mode.
Your freighters still have 12 months of intended deployment. As I said before, it's not wrong, just unnecessary.
Your gravitational survey vessel has way too much maintenance life compared to its intended deployment. You can afford to cut that down to two or three years instead of 15 if you want it to keep an intended deployment time of 1 year. I try to match the two on my ships, with a little wiggle room left over on maintenance life since that side of the equation is more up to chance.
Regarding NihilRex's suggestion to use tiny fuel storage: this works, in part, because a maintenance failure or internal hit on a ship with fewer but larger fuel storage components is more likely to take out a huge chunk of your fuel tank tonnage, thus costing more maintenance supply points per breakdown or per hit. Smaller fuel tanks effectively compartmentalize the damage. The trade off is that smaller fuel tanks cost more build points per ton than larger ones, so the ship costs more overall. It's a good suggestion to keep in mind when you need to squeeze a longer maintenance life out of a ship and you don't have room for more engineering space. However I wouldn't take it as a must have strategy in all ship design.
I suspect the remarkable increase in maintenance life is due to you using this trick, and in my opinion you could afford to do without it. You probably don't need 15 years of maintenance life, and in terms of combat survivability, if the Apollo gets hit at all, it's probably not going to survive.
