In addition, they need freight transport to be fast as well, to get materials to their destinations quickly with minimal time exposed to enemy attack. If using slow-poke Terran ships impedes timely shipment of required parts and materials, faster Loroi ships will be used...building an extra ship won't help if its parts don't arrive in time. The apparent limitations on our own ship-building capacity make this even more unlikely to be much help.
We'd both be better off if the Terrans simply shipped raw materials to the Loroi, but the war may not last long enough for us to ramp up our productivity enough to matter in even that limited respect.
Building one extra ship won't help. Building ten extra ships will. If you're moving bulk goods (raw materials, foodstuffs, etc.) the speed that they need to get to their destination doesn't matter nearly as much as if you're resupplying the front line. A lot of boring, routine rear-area transport could be handled by slower (really at crossing distances of just a few to ten AU, 2 or 3 Gs of acceleration is pretty okay for this kind of cargo running) human-made "junk" ships.
Let me quote Arioch here to establish a base time of about a week to cross a system under normal transit speed:
Arioch wrote:System transit speeds need to be up around 1% lightspeed (3,000 km/s) if you want to be able to cross the system in less than a week, and I wouldn't want ships to have to waste too much fuel slowing down before every jump. On the other hand, you want the couriers to be able to get up to jump speed relatively quickly from their relay bases; 1,000 km/s takes a little bit less than an hour at 30G. So we need a pretty wide range of possible jump speeds.
So you're looking at, for the terran clunker using a paltry 1 G of acceleration starting from a dead stop in deep space...
speed = time*acceleration
time to reach cruising speed = .1c / 1 G = 3000 km/s / (9.8 m/s / 1000 m/km) = 306122.449
So about 85 hours to get up to your cruising speed (yes I'm ignoring some details but they don't really change the comparison of 85 hours to 2.8 hours at 30 G to reach the same speed). And then another 85-ish to decelerate to whatever the correct orbital velocity is for the planet you're circling. So call it "an extra week of transit" time for your bulk goods. I'm sure there's plenty of shipping in the Loroi Union that could be handled by these kinds of ships without any noticeable loss of efficiency for the Loroi's industry. This would free up faster Loroi-(or allied-) shipping to directly supply those industries that are time critical as well as troops at the front line, gives the humans something to do that makes them a useful ally for the war effort, and it doesn't depend on any exchange of actual technology by either side (surely a plus for the xenophobic Loroi).
Other secondary industries could be offloaded onto the humans, like making Loroi Standard Military Boot Polish Color 7, freeing up the Loroi chemical industry to make more useful and higher tech things (like Super Duper Bug Spray). Unless the Loroi require their boot polish to use highly advanced nanotech so that it auto-polishes itself on the boot for a couple weeks, this sort of simple, but essential, industry can be outsourced. Make those silly humans do it, so the proud Loroi civilians can make better, shinier things that require their level of technology.
It's less about "lower materials cost" and more about "well these primitives have a bunch of shipyard slips that can build things (transports) we can use even if they're inferior, which lets us use our own ship building capability more effectively for the war effort" and "they can make lower quality but acceptable copies of some of our non-combat equipment like uniforms." (And then the Loroi discover japanese pornography, internet memes, and viral videos and their civilization commits suicide as it descends into a mass of screaming telepathic minds, lolcat images, and angry men hitting computers.)
I think it's somewhat obvious that the Loroi don't have a lot of spare shipbuilding capacity, either because they lack the infrastructure or the raw materials. Digging up ore or smashing asteroids to get it shouldn't be hard at all for their tech level, so the actual supply of raw materials shouldn't be much in doubt. The infrastructure though? It's implied somewhat that they have supply issues in the comic (and elsewhere in the various discussions on the board as well for what that's worth), so if the bottleneck is in supplying their troops, well, we can help with that by supplying slower, but still useful, transport capacity. If the bottleneck is in the actual infrastructure of building the ships due to a lack of facilities, well, we can help relieve that by building slower transport ships so they can use their limited capacity to build combat ships instead of so many transports. Even if the relief is rather limited, I don't think a sane military planner is going to turn down any chance to get a few extra warships to the front line during a life-or-death struggle.
And now I'm starting to ramble...
