As one of the people who made a request to get Fleet Defender on GOG, I'm really happy it's finally available. However, I have to make a further inquiry: when is Linux support coming? I confess that I'm still quite green when it comes to Linux, and that I could probably get what I currently have to run somehow, but it would be nice to have the worst of the work taken care of.

This is a DOS game which means, that you need nothing more than DOSBox for Linux to run it under emulation inside DOSBox on Linux.

You can use the DOSBOX package provided with your linux distribution.
