Well, it depends on how expensive the electronics for the system are. It requires high-temp superconducting magnets to work, after all. And probably fairly high-grade steel. It's not like they're going to invent these things and then suddenly they can mass produce them cheaper than comparable gas turbine engines.

Is there not a way to thermally insulate the magnets enough that liquid helium cooling would work?

First off, I believe there is zero moral difference between killing and enabling killing.

Then I look forward to your announcement that you're becoming Amish. All technology is dual-use if you're inventive enough.
