US draws up plans for nuclear dronesApril 2, 2012
American scientists have drawn up plans for a new generation of nuclear-powered drones capable of flying over remote regions of the world for months on end without refuelling.
The blueprints for the new drones, which have been developed by Sandia National Laboratories – the US government’s principal nuclear research and development agency – and defence contractor Northrop Grumman, were designed to increase flying time “from days to months” while making more power available for operating equipment, according to a project summary published by Sandia…..
The Sandia-Northrop Grumman team looked at numerous different power systems for large- and medium-sized drones before settling on a nuclear solution. Northrop Grumman is known to have patented a drone equipped with a helium-cooled nuclear reactor as long ago as 1986, and has previously worked on nuclear projects with the US air force research laboratory. Designs for nuclear-powered aircraft are known to go back as far as the 1950s.
The research team found that the nuclear drones were able to provide far more surveillance time and intelligence information per mission compared to other technologies, and also to reduce the considerable costs of support systems – eliminating the need, for example, for forward bases and fuel supplies in remote and possibly hostile areas.
A halt has been called to the work for now, due to worries that public opinion will not accept the idea of such a potentially hazardous technology, with the inherent dangers of either a crash – in effect turning the drone into a so-called dirty bomb – or of its nuclear propulsion system falling into the hands of terrorists or unfriendly powers.
The potential impact of nuclear-powered drones can be gauged by comparing them with existing aircraft such as the MQ-9 Reaper, which is used extensively in Afghanistan and Pakistan in operations against insurgents. The Reaper presently carries nearly two tonnes of fuel in addition a similar weight of munitions and other equipment and can stay airborne for around 42 hours, or just 14 hours when fully loaded with munitions.
Using nuclear power would enable the Reaper not only to remain airborne for far longer, but to carry more missiles or surveillance equipment, and to dispense with the need for ground crews based in remote and dangerous areas.
