Toying around with some early FAC/Tender designs, currently purely as a theoretical exercise and to see if there's any components I could design to improve them. (eg. the FAC's could use a dedicated size 3 engine to improve fuel efficiency)
Curious to see the thoughts and comments of others.

My own initial thoughts on the designs, for the tonnage invested, the Tender has a woefull capacity of actual attack craft, and obviously they'd need to operate with a dedicated sensor platform. Some tonnage could be freed designing a Squad 3 jump drive, alternatively the jump drive could be stripped entirely, because as it stands the vessel isn't capable of independent operations anyway.
I only have 6000 ton naval yards at the moment, so there's no rush to get this to production, but I've not really played around much with fighters/carriers before so I thought I'd throw some stuff together to get a feel for what they could do. Those idle fighter factories are staring at me every time I review my construction. Lazy bums, getting paid for nix. :P

The only thing that I see that could be glaringly problematic is that the FAC/Fighters are so slow. 4km/s is a turtle for something so small to be involved in combat ,especially for the laser craft. Those will get toasted by any sort of PD/AMMs if they move in to attack . Its less problematic for the missile one since it looks like they've got 20mkm range. I would remake the engines with a higher thrust multiplier if you can, and try to get them to at least double that speed if possible. Otherwise I would hold off on production until they can be made faster so as to avoid PD. I suppose the missile ones could be used now as a stop-gap.
But that's just my oppinion

For the early-game Nuclear Pulse erra 4200 km/s is a perfectly acceptable speed suitable for fighting opponents of similar or lower tech. Don't try using them against spoiler races though.
The P-1 laser fighter will be useful for mopping up crippled enemies and enemy civilian vessels without wasting expensive missiles, but will only be useful offensively against an NPR fleet that relies on short-range messon or railgun fire. I've seen small squadrons of similar designs kite NPR meson-armadas into junk, and then turn to vaporware themselves when their next target proved missile-armed.
One improvement: Give the Fire-Control the 50% fire speed, 50% size modifier in return for a larger range multiplier. Their best tactic will be long (beam) ranged snipping, and the laser is only firing at 4200 km/s anyway.
The missile fighters look solid, for the tech level. You may consider replacing one of the launchers with a magazine for self-reloading while deployed, but that's just personal preference.
Stripping out the Jump-Drive is a good idea. That will drop the size down to 9,000 or less, cutting the required shipyard expansion in half. Then design a new, smaller, cheaper, jump drive to put on the dedicated sensor ship you need anyway. A squadron of three carriers plus the jump/sensor ship might be enough for offensive action.
Alternatively, replace the P-1s with dedicated sensor-fighters and design an escort carrier to accompany the Guardian that replaces the jump drive with extra hangers/passive sensors.

Taking the previous replies on board, and a little research and revision later leaves me with these designs :

As can probably be inferred from the hull designation, the Chihuahua class will be intended to serve as a squadron leader for regular destroyers as well as the FAC tenders. I think I've over ranged the AMM's a bit, however reducing range to 1m Km only nets a single extra agility point at current tech levels, and well, that fleet defence missile warning radar was to juicy not to match the range. Magazine is worryingly shallow, but I'm trying to squeeze a lot of capability into a small platform. Possibly going to suffer the generalists curse, only managing to be poor at everything it tries to do.
Dropping the Jump drive on the Guderian however, has made the design look much more pleasant on paper, room for a 6th boat, expanded magazines to support the Missile boats, and improved range, all in a smaller package.
The PT-1 only saw a minor revision, trading out the Triple S1 engines for a single S3. A major revamp on the P-1 significantly alters its role, placing it firmly in the fleet defence interceptor camp I think. Interestingly, crew requirements left it with quad S1 engines, the S4 requiring almost twice the crew, for which there just isn't enough room.
So guys, Chihuahua jump tending and spotting for 3 Guderians, with a small 12 PT-1 strike package, leaving 6 P-1s flying CAP. Workable light strike solution alongside dedicated destroyer squadrons?
edit because I forgot to modify the flight crew quarters on the guderian for the FAC's new crew requirements.
Note : The 10m km AM fire control will only pickup size 6 and under missiles at 1m km apparently. Thoughts on trading down range on the AMM's to get the extra point of agility? Manouver 12 would cut maximum range to 1.8m Km

Looks good to me.
The magazine, though, probably will be a problem (as you admit) if you do "run into"(See: get into range of) someone who likes to throw ASMs while operating one of these squadrons independently. You'll blow through the magazine pretty quickly w/only 12 salvos at 15 seconds each; 3 minutes worth of missiles. Hopefully, though, the fact that you're using fighters to deploy your ASMs will keep the enemy out of range of your base ships (which, I suppose, is the whole point of fighters/bombers anyway).
Though if that is supporting standard DesRons, as you say, then I'd say its good to go as the DesRons' AMM and PD fire can cover the squadron from ASMs.

Sorry to be late to the party here but I would like to give one suggestion that I think would enhance this squadrons performance.
If the active sensor was dropped in favor of some stronger passive sensors or magazines you could use one or two 500 ton scout crafts with active sensors instead. The major benefit here is that you don't want your rather defensively weak squadron anywhere near an enemy. And since your strike crafts has such long strike range you can't really make good use of their strongest ability as it is.
All in all, scouting in force usually need either more or bigger ships. In the early game I rather just use scouting squadrons with defensive weaponry and equipped with some beam ASM if they are caught by a faster enemy. My earliest scouting in recon force usually is about 20k in size, but this generally need some investment in jump engine size efficiency to be economically sound. It is totally viable at Ion tech depending on your other priorities of course. That would be one command/light cruiser and two light carriers. They would in general be about 2/3 defense and 1/3 offense.
