FAC Tender

[justleroy (OP)]

I recently encountered what I think is a precursor race in the Alpha Centauri system and designed FACs and a tender to counter them, hopefully.  I want to be sure I haven't forgotten anything before I start building these ships as they are going to be big and expensive.  Please look this design over and give me your ideas for what I forgot or can improve.

General terminology seems to be that FACs are craft between 500-1000 tons (and generally fairly self-contained as far as fuel and support goes, though short ranged) whereas ships <500 tons that aren't meant to spend more than a few days undocked are considered fighters. So generally I'd consider your design a Carrier and fighters rather than a FAC tender and FACs.

As for the ships themselves, they look pretty good. The missile platforms have a much longer fire control range than their missiles can reach, but this might be considered future proofing as you can switch out more advanced missiles later. I'm also a fan of using railguns instead of Gauss on Point Defense fighters, but that depends on your tech. Lastly, you might consider a scout fighter with active sensors that can paint targets for the missile fighters, so you can make long range strikes.

[justleroy (OP)]

This is ironic, considering what I posted on the Academy yesterday.   

You are right, though.  These are technically fighters.  I went with FAC for one reason (and a role playing reason, at that): the number of crew.  Fighters (at least in the sense I am familiar with) generally have one or two crew - a pilot and a navigator/tac officer).  Larger craft, such as bombers, AWACS, etc. , are usually too large and slow to be considered fighters.  I may be able to play around with the deployment time to get the number of crew down, but I'm happy with these designs.

Thanks for your input! 

[3_14159]

Just some things I noticed, though they are mostly a personal preference:
a) I agree on the sensor fighter. Your fighters have ca. 400mkm combat range, your sensor can only see to 200mkm. Plus, if you use it, the enemy knows where your mothership is, and your anti-missile defense isn't that good.
b) Speaking of which, why don't you take CIWS on it instead of meson cannons? Sure, it can then only defend itself, but it's going in alone anyway.
c) Deployment time: Your FACs have 0.3 months deployment time, but only 13 hours of fuel. If you cut it to... 0.1 or 0.01 months (not sure which), you'll get a further reduction in crew to 2 or so people. Could be worth it.
d) Your missiles seem way, way too slow. Your FACs/Fighters are nearly as fast as the missiles they're firing. Plus, the to-hit seems abysmal, considering your engine tech. I'd say cut the warhead to 4, and get the rest into engines.
e) Wait, what? I just noticed you have 5000 cargo, plus cargo transfer. What's that for? Missiles are stored in magazines, of which you (by gthe way) don't have any. So, cut the cargo space, and get missiles in it. For the same tonnage, you should be able to pack about... 600 or so missiles. Which is something like 36 salvoes, so cut it further and increase the hangar size. You're launching 9x4 = 32 missiles per fighter launch, for a total of 160 damage. Any serious PD by more than ten thousand tons will almost certainly remain undamaged.

And that's what I just noticed. Apologies if I sound inconcise and/or rude. I hope it helps.

[joeclark77]

I can't figure out where all the space on the FAC tender went.  I have a carrier with 6000T of hangar space that's only 20kT and has room for lots of fuel, missiles, and maintenance supplies, as well as 5 or 6 layers of armor (at least).  Somehow I suspect most of your tonnage is engines which are only there to push around your massive tonnage of engines, and  you wouldn't lose too much speed by dropping them.

For this role, a slow FAC tender is as good as a fast one.  Your only defense is a good offense.  Your design has to be intended to spot the enemy as far away as possible, send out fighter-bomber waves to pulverize them with enough time to come back and reload for a second or third volley before the enemy close in to energy range.  If the spoilers reach your carrier they'll kill it whether it's 20kT or 40kT and 1kkm/s or 3kkm/s.  (Unless you can direct the whole fight with your carrier sitting on the jump point for a quick escape, but I think that's unlikely.)  You've got excellent sensors and that's good.  Maybe a little too good -- how many tons are they?  It's nice that you've got one for FACs, too.  Point defense is good in case the enemies have good sensors and can fire their missiles before your missiles hit them.  As somebody has mentioned, drop the cargo pod and add magazines.

I would try to get those Crow fighter-bombers smaller if at all possible, so you can carry more of them in your hangar.  With box launcher tech, which you have, it is usually possible to get 2-3 missiles and maybe 4 on a fighter under 250T.  2HS are engines, 1HS is fire control, and 2HS are for missile launchers, fuel tank, and crew quarters.  Set the intended deployment time to 0.1 months (aka 3 days) and your crew requirements will be cut down to 1 or 2.  Remove the bridge and engineering spaces if they are still on there by default.

I think your engines are darn fuel hogs

I have thrown together the carrier below (also magneto plasma engines)

6x Hermes Fighter-Scout   Speed: 13812 km/s    Size: 6.95As you can see, I haven´t any PD on this baby (mainly, because my carrier doctrin says: Don´t let the carrier get spotted, let the fighters do the fighting)

My engines are very likely to be larger than yours (mine are 750 tons each), but you have to consider this:

I have 5000 tons of fuel plus 6750 tons of engines on board for a total of 11,750 tons
You have 10,350 tons of fuel alone aboard, so my larger, less powerfull engines more than make up for this fact by the increased fuel efficiency.

Yes, fuel is needed to refuel the fighers carried, but you carry 13 FACs with 5,000 liters fuel each for a total of 65,000 liters of fuel. Even if you use them for 10 sorties, this would be only a drop in the bucket of your fuel supply, so your 10 million liters are obviously needed to keep the carrier going.

Because my fuel/engine part use so much less mass/space, I can put a whooping 13,000 ton hanger deck in, about two and a half the size of yours. If you think your strike group can take on the enemy fleet, think what _my_ strike group could do.

You might also notice, that I don´t have any active sensor on the carrier, but two huge (1000 ton each) passives. This is to get the general area where the enemy is and then send in the strikegroup, which will include a few recon fighters (see carrier doctrin above)

And here my fighters (also thrown together and not realy optimized)

Size 4 missiles, because that is what I am using in my game and way too much maintenance, but I don´t have the tiny enigneering space researched yet. I also don´t have the tiny crew quarters, which is why there are lots of spare berths on my fighers. With those two items researched, my fighters would probably approach the speed of your missile FACs

For what it's worth, here's my carrier design.  Note that it doesn't have a FAC detector or missile detector, as it is meant to be in a fleet with ships that provide those capabilities.

It could carry twenty of these fighters that carry 3x size 5 missile each... in your case they could carry 5x size 3 missiles.  The fighter is internal fusion drive, so your version would be a bit slower, but not incredibly so.

I'm debating making her jump-capable.  I have jump drive efficiency 10, currently, so jump drives are as bad as they could be.

It's looking good.  I once tried to make my carrier into my jump ship, and I found it took away too much space that could have been hangar space.  Now I have a "jump cruiser" that leads the fleet, and does a bit of anti-missile defense as its second job.

[Brian Neumann]

I usually find that the jump ship is such a priority target that having extra point defense and passive defenses (shields/armor) are a must.  If there is any extra space left over I usually put some good passive sensors, especially thermal to keep them from being caught by small ships getting to close.

This is the jump tender I came up with for my carriers.  I found that I really needed to fill the ship up with stuff to reach 24,000 tons, so I gave it missile racks, maint.  supplies, and extra fuel to act as a collier/supply ship/tanker as well.  It also has the sam EM and thermal sensors as the carriers.  I figured it's going to be sitting at a jump point for perhaps weeks at a time, might be good if it could also see if there's anything approaching.

Instead of CIWS you might want to think about some general anti-missile defenses that can protect other ships in the fleet, for example gauss turrets.

[justleroy (OP)]

I just put the CIWS systems on there because I needed to get to 24,000 tons.  At 385t each, I get the tonnage I need along with a decent "oh, crap, the point-defense frigates are all dead!" last line of defense.

Two to four of these will accompany the jump tender, and 6 to 10 of them in the carrier group. 

[mckamx]

IMHO (which you are welcome to ignore), unless you are expecting large number of single missile salvos, you could reduce the size and cost of your Perry's by reducing the number of fire controls.   Each fire control targets one salvo or group of weapons at one target or salvo of missiles.   

My equivalent designs tend to have one fire control per quad turret or 10 missile launchers.   I would also recommend more magazine space: you can go through 266 missiles in a hurry when the NPR's start using their defensive missiles in an offensive role.

[justleroy (OP)]

Good point about the magazine space.  The low amount of missile reloads was a concern.  So, I took your advice and almost doubled the magazine space and added two more gauss cannon turrets.
