Whelp, we presumably cut them off just as much as they cut us off. And given their embarrasing lack of technology, I am suspicious of what compelled them to be so aggressive.
C.S. D.F.A. "Perversion Personified"
A shuttle, with storage capacity replaced with ammunition storage and missile ports along the side. We give up on complex missile ports and just leave the whole thing unpressurised, our crews can use space suits, we can even give them air-lines if they want to feel special... Although to prevent internal depressurisation during difficult launch periods we only depressurise the cargo slowly after leaving the atmosphere, storing as much of the air as possible.
The missiles themselves use primitive thermal guidance and a warhead based upon combining the fuel and exygen elements of our fuel, getting something similar to thermite which will make a mess of a hull and produce enough radiant heat to be a problem for personnel even if it fails to splash... The steering is pretty primitive, it is advised to use it only against shuttles from behind them, or when they are in limited manoeuvres such as atmospheric transitions or orbits, but missile spam should serve well enough in desperation. Mostly this will serve as a support vessel by bombarding ground targets, at which point the dubious aiming is less of an issue. Note that due to their dedicated combat role, missiles do not need space for long-voyage fuel storage, crew and life-support, storage and maintenance spaces, various other things like that, so they are still optimised to out-perform our own shuttles in terms of turning and thrust, provided that the guidance chooses to work that day...
Hump-thumper Torpedoes
We continued work on the miniaturisation of the fusion generator, and built a shuttle around it. This shuttle can be flown at an enemy target and overloaded...
Because we need to salvage something from this disaster...
