Yep, it's just the texture of the blue blocks.

would the vessel work without the dlc?

I like the look! I'll have to give it a try. Normally I'd worry about reactor fuel on earth but I am using a uranium mod that adds it back to earth planets. I've been needing a good fighter and turret though! Thanks :)

nice design, killed like 5 bases with this :P. quick menuveur. one sugession-- add a turret below, not on top.

I like this, nice work, as always.

Very cool fighter, very reminiscent of the Tempest.
