Ion era fleet design
« on: June 02, 2017, 06:16:20 PM »
Hi everybody!

 So here is my first "big" ship designs.    Almost everything under 10k Rp is researched.    I would like some feedback before I start to build these ships because I have only minimal amount of duranium left and I don't want to waste it.   

One fleet is going to contain:
2 Galactica JC,1 Vigilant SC,3 Helgoland EC and 4 Viribus Unitis MC

The recon fleet is much lighter: 1 Ranger SC, 1 Helgoland EC and 1 Viribus Unitis MC

And I would like to have some monitor fleet possible with 2 or 3 Monarch.   

I am still a beginner so I would appreciate some constructive critic.    And sorry for my english but I still need some practice.   

The Ranger class is a simple first jump/ recon vessel to try the jump points and habitable worlds before the defensless commercial and survey vessels put their life in risk.

Galactica Jump Cruiser sole purpose is to carry it's fleet through the jump points.    This ship has only limited self defence capacity but I intend to use it in a fleet anyway.

The Helgoland escort cruiser is not a finalised.    I still thinkhing about turreted gauss or meson cannons.    Maybe the combination of the three.    (My turrets are capable of 16.   000km/s tracking, but the quad variant is 2141 tonnes, the twin variant is "only" 1160,5 tonne.    The meson quad cannon is 1148 but it has only 4 shot per 5s)

The Viribus Unitis Missile Cruiser has some room for improvement to say the least.    I am not very pleased with it but I have no idea what to change.

And finaly the Monarch class Monitor.    The goal was to have a ship which is capable of guarding jump points in the Sol system without the use of ordenance and a deployment time of 36months.    And to kill a ship less than a minute.    ( 64 demage per salvo and this is just the 20cm railguns)

And I am also planning to build a missile escort cruiser but I already have a big ordanance and resources shortage so I postponed that project.   


And I have some FAC-s for planetary defense and hit and run tactics.

This post is already long so I will skip the PDC-s and support vessels.   

 So I hope I was understandable and my ships are not trash.   

Thank you in advance for your answers.   

And the game is really cool!

The missile cruiser could be improved by using reduced size launchers.  The Viribus Unitis will likely be engaging targets at 87mkm; it will take your opponents several hours to cover that distance.  If you use reduced size launchers, you can fit more of them in, meaning much larger volleys.  Volley size is typically more important for anti-ship missiles than how fast you can fire follow-up volleys, because you're trying to overwhelm your opponent's point defense.  An enemy fleet that can shoot down 100 missiles in 10-missile volleys spaced 60 seconds apart might not be able to stop a single 100 missile volley.

Your fleet composition seems good.  I would consider adding another Helgoland, beam FAC's and fighters, especially meson ones, could pose a big threat to your fleet.  Your short range defense is all in railguns, which have quite a low tracking speed since they can't be put in turrets.  You have reduced accuracy against any target faster than your tracking speed.

Marcel,

For your first set of ships, these are pretty good. I like that your fleet assets all have the same speed, deployment time, and range. There are a lot of ways to build a fleet and most of them are not wrong. I'll make a couple of suggestions that gel with my style of play.

I usually give my fleet 12 months of deployment.  24 seems longer than you'll need and you'll gain some space.

I'd change your three 240 engine configuration to two 360 engines. You'll gain a marginal increase in fuel efficiency.

I'd increase your engineering spaces for your sensor ship.  I usually want to have a little better than twice my max repair in msp so I can fix components that break down without returning to a shipyard.

Your missile ship is not bad. When I build missile ships, I try to put the largest number of reloadable launchers per tonnage. Your launchers are reduced but you can make them smaller.  I'd go to 25% launchers. On that.

Good first fleet!

TT's right, I really want to stress that it's a great thing that you've matched all your ships' speed.  Mismatched speeds typically means wasted tonnage on the faster ship, because you aren't using all your EP.  You could've gotten the same speed out of smaller/fewer engines.

One thing I might add is some sensor buoys on the Ranger.  To make them, make a missile with no engine or fuel, and all of it's MSP in sensors.  A missile with no engine will sit where it was launched forever.  Would be good to drop them at jump points as you explore them so you can make sure nobody else is using them.

Engines too stressed for my tastes. It's actually near the performance-optimum you can get for the tonnage, but you could  halve fuel consumption for only a modest decrease in capability by shifting tonnage from fuel to bigger, lower-multiplier engines.
As it is, you have very long-endurance ships that are hampered by fuel use; I'd accept shorter standalone range and bring a tanker (4000km/s is very achievable with commercial engines - 50% of tonnage at 0.5 power).

Slightly higher beam fire control than weapon range is good, but it seems a bit excessive on some of the ships.
I'm not a fan of slow-firing railguns; at 15s reload rate you're usually better off with 2 fast-firing lasers with the same per-shot damage. For this reason, railgun calibre tech usually trails capacitor tech for me.

The missile cruiser may struggle against point defence, even tough the AI is usually not very good at it one of these ships may not get through.
I'd consider either a higher reduction of launcher size for larger salvos, or one fire control per launcher (expensive at this kind of range, but cheaper in the long run than having a good portion of your missiles shot down).

*

On a more general node, Aurora subtly encourages not using the "default" configuration.
4000km/s ship speed with 4000km/s base tracking speed: If your ships go faster, they benefit from faster tracking speed. If your ships go slower, non-turreted weapons still track at 4000km/s.
1.0 power engines are rarely ideal because of the way cost scales. A 1.2 power engine is 1.2 times as expensive, a 0.8 power engine is 0.64 times as expensive.

Just a little note: the Ranger class is too expensive to be used as a first explorer of new systems for my taste.

Thanks for your opinions!

 I would like to stick with the 1000 tonne engines I even considered multiple 500 tonnes but the fuel efficiency was terrible.  My next generation ships will  be 0. 8 power engines but those will be magneto plasma drives. 
I also modified my  ships to 12 months deployment time and then I spent the extra space for enginering sections.
I made some variants for my Helgoland and Viribus Unitis class cruisers and I add an extra 1000 tonne for my Monarch class monitor(1 extra layer of armor and some more fuel). 
And about the 15 sec reload time.  I am not happy with  the 15sec but it would take a year or two to improve it to 10sec.  Earth is already out of every mineral so I have to field a fleet as soon as I can.

So wich one is the best from the 3 Viribus Unitis and the 3 Helgoland?

Of the Helgolands, the railgun version would be best though not ideal. Some additional speed, normally expensive, can be had almost for free: 5000 or 6000km/s with matching fire control means you can sacrifice 2-4 guns with no loss of point defence capability, and since "Speed is armour" you may also get away with reducing armour by a layer. It may be possible to make it a better ship simply by taking things away and getting a matching fire control.

Either of the revised missile cruisers are fine, as far as their armaments go.
The 25% launcher version almost perfectly matches reload rate and missile endurance, nice! Which will be preferable depends on doctrine. Potentially huge alpha strike vs. ability to reload from colliers, more ordnance carried and being less fiddly if you're happy with measured salvos. If you plan for only a single missile cruiser ("I'll rely on beams if I can, this is my backup plan"), I'd go for box launchers.

Don't like Thor's main artillery, I'd also prefer 5000-6000km/s, otherwise solid. I'd probably use a single fire control: you already have point defence ships capable of tracking multiple salvos, may as well benefit from the increased accuracy on all guns.

Bem: Very long Maintenance life, but MSP just under 2x Max Repair is awkward.
Maintenance life, deployment time and range don't quite match up for any role I'd have for it,  but these things depend on all sorts of assumptions and it looks effective enough.

So assuming the Helgoland is meant to do point defense, not kill ships, I think the railgun one is best, but not by much.  The Gauss one is a close second.

The railgun one's advantages is better firepower; it's got better rate of fire than the Gauss one.  It might be a little worse at killing missiles than the Gauss variant, due to worse tracking speed, but it'll be better at killing ships because it has better RoF.

The Gauss one's advantages are armor and tracking speed.  Because of the way damage templates work, 6 armor is MUCH better against beam weapons than 5 armor.  To penetrate 5 layers in one hit, a laser needs to deal 12 damage per shot.  To penetrate 6 layers, it needs 21!

Both the new missile cruisers are better than the original.  It's up to preference really which you build.  Do you want to be able to launch one huge salvo at the expense of not being able to use colliers?

Iranon is right about the Bem, deployment time, maintenance life, and range are probably mismatched.

Assuming the Thor is not meant to replace the Helgoland, I think your armament/sensors are odd.  You've already got the Helgoland for missile defense, so why have the 10cm railguns on the Thor?  Why not have more 20cm railguns?  I'd ditch the small fire control too.  Or just ditch the Thor completely and make more Helgolands.

I don't think the Thor is a bad ship, mind, just that it's niche already seems filled.
