Power will be supplied by an onboard 3.7 kilowatt-hour lithium-ion battery. That battery will drive a variable-pressure pump which operates all of the hydraulic systems. The pump makes ATLAS much quieter, but introduces a complication for the teams: it can be run at low pressure to save power and then switched to high pressure to get harder work done. Managing power consumption will be a very difficult task, but DARPA has also upped the prize money to $3.5 million in total.
"There's a legal void that needs to be plugged," said Claude de Ganay, the opposition member of the National Assembly spearheading legislation to be considered by parliament on Feb. 5. The proposals would classify atomic energy sites as "highly sensitive military zones" under the control of the Ministry of Defense, according to an outline provided by de Ganay.
They already seem to have some ideas — their research proposal says such an anti-drone weapon would "disrupt these platforms' autonomous flight-control and navigation capabilities or cueing a weapons system like the Remotely-Operated Weapon Station (RWS) or other medium or large-caliber weapon." The system would be mounted on vehicles or at Army installations. More interesting, the Army proposal also notes that it might be mounted on UAVs, which raises the possibility of using drones to shoot down other drones.
The U.S. tried a similar tack with Clipper in the 90s. As we all know, terrorists with any technical chops are unlikely to be affected, given the vast amount of freely available, military-grade crypto now available, and the use of boring old cold war tradecraft. Ironically, France used to ban the use of strong cryptography but has largely liberalized its regime since 2011.
