Probably sixteen (Lances -- re: how many did the Border Worlds capture). I'm pretty sure they'd have to give them back to Confed after the conflict, though...
So they have 2 (3?) carriers and a few fighters?
During WCIV they had eight 'carriers' -- two Durango-conversions, two transports capable of launching (but not recovering) fighters, two Landreich Escort Carriers... and then the Princeton and Mount St. Helens. We know for a fact that Confed got back the MSH, and it's pretty probable that they got back the Princeton too... and, of course, the pair of escorts would have returned to the Landreich.
And Confed took the Intrepid for some reason.
Weren't the Eagle-Class *new* in WC3? I'd say if they have anything they've gotten some Ranger's or something. Maybe they could have something as new as a Bengal, perhaps.
The Eagle-type was new in WC3, and is apparently still in use by Confed -- it seems to be part of their current military scheme (fast light carriers paired with heavy carriers). Given that Confed still maintains the 50-year-old Concordia class in 2681, it's doubtful that they're selling off *new* ships.
The Border Worlds is still crippled by a lack of shipyards when 'buying' surplus Confed ships -- Confed doesn't sell you a warship lock stock and barrel... they sell you a picked-over warship. You have to do things like refurbish and arm the ship... as we see the Landreich doing in False Colors. And of course, despite the fan fiction notion that everything is for sale, I'd maintain that it's only very, very outclassed capital ships that get sold to other nations... (the United States doesn't sell fully armed nuclear powered aircraft carriers to Mexico...)
The Landreich only links up to a backwater of Kilrathi space, and even during the war was considered a low priority area. The BW is in a direct line with a lot of the Kilrathi front, so claiming that BW pilots have more experiance post war is hardly invalid. Plus if the Border Worlders fought as part of Confed in the Kilrathi War, more of their senior pilots/commanders could have Confed training and frontline experience.
I don't think this is a valid argument -- the war was fought in the Border Worlds, but not only *by* people in the Border Worlds. Confed trained their pilots on the inner worlds and then sent them off to fight... I could certainly argue that HD units in 2673 in the Border Worlds would be far better trained than Confed core worlds militia units... but only equal to those in the Landreich. And by 2681 the people trained in the war will have advanced in age quite a bit...
In addition, the Border Worlds probably have more ability to build/manufacture/modify their own fighters andf get them in service than the Landreich does. Even with the short time they had in 2673, they were able to get the Banshee, Vindicator and Avenger into combat, albeit in small numbers. The Landreich, despite having been around much longer,were still relying solely on Confed cast-offs and the fighters off the Karga as late as 2670. So when it comes to replacing losses (asssuming Confed doesn't sell anymore to either side), the Border Worlders might have an edge.
The Border Worlds builds their own fighters in the same sense that the Landreich did in '69 -- by sticking new weapons and parts on old ships. Making a shuttle into an Avenger is the same thing as making a Ferret into a... Ferret with a big engine thing
UBW has Confed around for the heavy stuff (Nephilim battle fleets, etc...), but the UBW still has its local forces. Otherwise it wouldn't have a 'militia'. And given the fact that the 'Confed Protection' led to at least one near disaster in recent history, I'm fairly confident that the UBW isn't about to turn everything over to Confed.
*Confed* has independant (and some dependant) militia units, though. And we've seen that officers from these units can transfer into regular Confed... but *never* that they're more impressive than a garrison squadron of Thunderbolts.
The UBW militia probably still has a force composition similar to what they had during WCIV, just with modernized forces. They've undoubtedly got newer fighters to replace the Rapiers and what-not that they were fighting the Black Lance with, and the Thunderbolts and Excaliburs are probably their primary heavy fighters. And the Intrepid has probably been replaced, as well, although not by anything as good as the Murphy or Plunkett that Confed uses. A few Eagle-class CVEs might be a possibility, though.
They presumably have what they can pay for. In 2673, when they had an immediate need for such craft, they could pay for twenty year old fighters... is there some reason they can buy ten year old fighters today? (Of course, we know the Intrepid went to Confed... although we have no idea why.)
As for the Landreich - they're in the boondocks. Where are they going to find anything to fight? Perhaps the occasional human pirate, but not Kilrathi pirates. The UBW is on the Kilrathi border, and we know from the WCP manual that Kilrathi pirates are still very much of a threat to human interests. As a result, the majority of Kilrathi pirate raids into human space are probably going to be directed at UBW interests, and somebody has to hold down the fort until the navy arrives to clean things up. Confed Navy is in the middle of peace time, and with no real opponents to challenge Confed's strength, the navy is going to be smaller, meaning that the weight of dealing with pirate raids falls on the local garrisons. Those garrisons are going to be militia forces, not Confed Navy. The navy won't arrive until after the raid is over, and someone needs to track the raiders back to their home.
Where will the Landreich find somebody to fight? Right across their border... the Landreich doesn't recognize the Treaty of Torgo, and they continue to fight the Kilrathi. Hralgkrak Provice borders the Landreich, and it's the home of the most well-armed and actively hostile of the Kilrathi warlords. And last we heard the Landreich wasn't exactly friends with Confed, either...
Furthermore, we *know* that Confed has been dispatched to the Border Worlds area to deal with pirates -- by looking at the same source you just used to prove that pirates exist (to wit, Confed is *more able* to deal with pirates than they were during the war when they couldn't spare *any* units...).
The Landreich no doubt has some excellent pilots, but they're starting to get a little grey hair mixed in with the black (or brown or blond). The UBW may or may not have as many older veterans (its doubtful that Hawk is the ONLY Border Worlder vet still in the cockpit), but I can almost guarantee that the ones that got in the cockpit in the last few years have seen more action than new Landreich pilots have.
Hawk wasn't trained by the Border Worlds. He didn't even live in the Border Worlds. He was a retired *Confed* pilot who fought for the Border Worlds because they paid his mercenary fee. I don't really see how the *year* between when we last see the Landreich's military (2672) and when we last last see anything with the Border Worlds (2673) would make the former "a little grey".
Case in point, the Landreich has fighters with corvette engines attached to them. Think of the time and ability it takes to strap a 20-year-old fighter onto a pair of engines made for a much larger ship...
This was in Fleet Action, when they were doing whatever they could to repell an invasion... by False COlors they seem to have a fairly organized military.
Not to mention, Kurger also seems to be able to skim some kind of ship away from ConFleet (That Destroyer when he defected, The Tarawa for all of a short while before The Battle Of Terra, The former Tarawa during False Colors)
The Tarawa/Independance was legitimately purchased Confed scrap.
