Mars defense probe
A from unmaned spacecaft design to Iner solar systom from attact from enemy of UFP. We got to see it first during best of Both worlds part two. We also never got to see fire any weapons at the borg cube. The borg cube was able destory them quit quikly. The fact charging at the borg cube sugjest that they had big warhead.
Guese work. They may or many not have had weapons fire smell caft never see evidice to back it.
