A graphic of a multi-kinetic neutronic mine.
The multi-kinetic neutronic mine is a weapon of mass destruction utilized by the Borg. The mine has a yield of five million isotons, enough to affect an entire star system. Shockwaves from the mine would spread over a radius of five light-years. In 2374, Seven of Nine proposed the neutronic mine as a means of delivering modified nanoprobes to Species 8472, noting that it would be "efficient". However, the fifty trillion nanoprobes necessary to arm even a single mine were well beyond Voyager's production capabilities given the time constraints, not to mention Captain Kathryn Janeway's ethical reservations about such a device. (VOY: "Scorpion, Part II")
- Curiously, the shape of the mines resembled that of the rogue Borg ship from TNG: "Descent, Part I & Part II, the size of the mine would be considerably smaller however, taking the size of a nanoprobe to be approximatley equal to the size of a red blood cell, 50 trillion nanoprobes take up considerably less than 1m3"
