Regarding the Loroi wave-loom device, is it what TV Tropes calls a "Wave Motion Gun": a big, typically spinal-mounted, gun or cannon that is immensely powerful and can often destroy a ship, or sometimes a fleet, in one shot?
Here's their definition:
"The Cool Ship needs an equally cool weapon. If it's a sufficiently humongous Cool Ship, it will be equipped with a Laser Beamon steroids: the Wave Motion Gun — an enormous Ray Gun that fires a massive energy beam capable of blowing away an enemy ship (in the "blow a battleship in half" sense), sometimes an entire fleet, with one shot, and maybe even blowing up an entire planet."
I think that space fighters could be a viable platform for delivering short-range weapons, especially things like short-burn kinetic-kill missiles that benefit from the launching craft's velocity, but must be launched from a dangerously close range that you wouldn't necessarily want your larger ships at. Fighters are slightly more maneuverable than larger ships, but their main advantage would be that they're more expendable. In earlier eras prior to that in the story, I think fighters would have made viable anti-ship weapons (delivering KKV or torpedoes to close range), but with the advance of point-defense weapons over time, this role will probably have been mostly taken over by unmanned missile buses. In the current timeframe of the story, fighters will have been relegated mostly to a defensive role as anti-torpedo and anti-gunboat platforms. The main advantage of fighters in this role is that you can put them in many places at once, and in locations that you might not be comfortable placing a larger, more expensive warship.
1. Actually I would say there could be several reasons: 1) The civilization may be afraid of having the fighters be autonomous, perhaps nervous about AIs or particularly advanced computers, but don't have the ability to remote-control fighters at very long distances due to comm limitations. 2) There's no FTL comms so remote-controlled fighters can only operate at short distances (relative to space) and for longer distances you require pilots. Other than Loroi telepathy, there isn't FTL comms in-universe right?
Number 2 would work if FTL fighters are possible and you want to try to do interstellar strikes without having a carrier present in the same system as the target.
One thing I was happy about when I looked up about your fighters is that they're big. They're not only 14 meters in length, like you find in many visual scifi series, due to having to fit them in studios for filming, but are close to 40 meters, or slightly bigger, in length. They're certainly not small.
2. Arioch I was looking at the maps on your website about where the territories of the races are located. Both the Loroi and Umiak territories are rimward of Earth, right?
Arioch, if one was to look at a map of the entire galaxy, how big would the Loroi, Umiak, and Terran territories look, in comparison to the rest of the galaxy?
For example, for maps of the Traveller RPG, people have made software that shows the size of "Charted Space" aka known space, in comparison to the galaxy and it is quite small (travellermap.com/?x=-400.433&a…. If one were looking at a map of the galaxy at the scale shown in the website, would the Loroi, Umiak, or Terran territories be around the same size?
In Traveller, charted space is about 2086.4 light years by 1043.2 light years. This space is divided into sectors, with each sector being 32 parsecs by 40 parsecs. It measures 16 sectors if you were going from the trailing edge of charted space to the spinward edge of charted space, and it measures 8 sectors if you were going from the rimward edge of charted space to the coreward edge of charted space.
That Traveller map is relatively realistic in scale. The Orion arm is only about 3000 light years wide and 1000 light years deep, so any area contained within the arm can't get much bigger than that (which is very small compared to the total size of the galaxy, which is 100,000 light years across). The known territory of Outsider is contained within the Local Bubble, which is roughly 1000 light years across. The bubble blows out the top and bottom of the galactic disk, and is connected to other bubbles up and down the arm.
Yes, heat is an issue; the rate of fire of beam weapons is probably limited primarily by heat management issues. On Loroi ships, the silver-colored fins and struts are part of the heat radiation system.
