Government scientists find it "disappointing" that "current political conditions will not allow use" of a nuclear-powered drone that can fly around the Earth for months. We do not. Why? Because the mere thought of a nuclear reactor flying around the heavens, snapping pictures of villages and possible firing rockets at them is absolutely horrifying, that's why. Set aside the fear of a nuclear reactor crashing in your yard -- these would be drones that would not run out of power.
ProPublica's Justin Elliott just posted a set of documents (PDF) from the Sandia National Laboratory in New Mexico dated June 2011 that detail the development and testing of said nuke drones. With the help of scientists from Northrop Grumman, the scientists mapped out the feasibility of building such an aircraft, not only from a technical point of view but, apparently, a political one too. The military benefits of such a weapon tool are pretty clear: Building a nuke drone would make it possible "to increase [unmanned aerial vehicle] sortie duration from days to months while increasing available electrical power at least two-fold."
