In that vein of thought, I'm working on a 2nd wave of thrusters using what I've learned to improve their efficiency, and by extension military application.

The best answer for that is "I'm not legally required to tell you I'm not a rocket scientist, but I'll bring that front and center anyways." I didn't read the help guides to understand that higher Exhaust Velocities are nicer, but the rockets all do their job of maneuvering planetary orbit so I was happy when I finished it and placed it on a craft.

The low mass and cost are admirable (so are the descriptions), but why do all your engines have such awful exhaust velocities?
