Made a new thread instead of starting it inside Terran Q&A because a previous discussion like this was separated into its own thread.
Macron accelerator as a Mjolnir cannon.
110m blowgun array gives 1414km/s projectile stream.(spinal mount)
Deterum pellets return as much as 66,000X the energy "put in" as fusion on impact/compression, shields cant stop the projectiles as they are physical mass and armour would not stand a chance no matter what its made of.
Using the same energy per second as a single Terran heavy rail gun gives ~7.58 damage per second(outsider damage numbers based on kinetic energy of a 200kg railgun at 400km/s once every 60 seconds) continuous stream of death, thats 455 damage per min in outsider numbers using the same energy from a railgun that does 53 per min(one shot).
"Beam" does not scatter like charged particle or plasma beams, and photons, so damage is not reduced by range.
As a spinal mount that sucks up most of the energy Terran battleship can produce lets make its power draw equal to 6 Heavy Rail guns.(6 heavy railguns are removed from the battlecrusier vs heavy cruiser).
Thats 2730 damage every 60 seconds or 45.5 damage per second that ignores shields.
Only downside is Its still super slow compared to particle/plasma/laser weapons but its outright devastating if it hits and it has a far higher effective range then rail guns both due to its speed and continuous beam nature that simply needs to cross a targets path rather then point intercept. Ignoring stream nature its around 14000km effective range(based on Outsider effective range for 400km/s projectile), if you decide to make it equal to 50 shots(~ same damage as railgun) every 60 seconds needing 1.2 second hit it has better then 50000km effective range. Against the largest Umiak super dreadnaughts 2.2km in size it has an effective range of over 300000km.(~1 railgun worth of energy hit every 60 seconds)
Did I mention the projectiles are effectively impossible to detect?
Stealth is effectively impossible in space, plasma and particle beams do not have unlimited range, Yet the macrons have almost no mass, they are not hot, they are not dense and they are so small radar/lidar wont work except for extreme close ranges when its already to late. A single ship jumping into an enemy system in a few minutes could complete a fire mission that would wipe out all major space infrastructure(that cannot dodge) across the system and do so with an undetectable attack until closest targets are hit, and it would be far more efficient then using missiles/railguns.
Conclusion
Macron Accelerators shooting fusion/fissionable material are pretty damn neat and realistic.
