A graphene-based de-icer developed by Rice University has been further modified to prevent icing by adding water-repelling superhydrophobic properties to passively prevent ice forming at temperatures above 7F. The de-icer, a thin coating of graphene nanoribbons in epoxy that is sprayed on, has shown in the laboratory the ability to melt ice formed on a helicopter rotor blade in a -4F environment. When a small voltage is applied to the conductive coating, electrothermal heat melted centimeter-thick ice.
A SpaceX Falcon 9 rocket is slated to launch a classified U.S. National Reconnaissance Office payload next year in an arrangement that appears to have been brokered by a third party.

Chinese researchers are developing a vision-based system for autonomous aerial refueling (AAR) in which both the tanker and receiver are unmanned aircraft.
Agricultural aviation is a market expected to be affected more significantly that most by growing use of unmanned aircraft for task ranging from aerial mapping to crop spraying.
LCC 20 USS Mount Whitney, the U.S. 6th Fleet’s flagship, became the first amphibious command ship to have an MV-22B Osprey tiltrotor land on its flight deck earlier this month.
When a small plastic component broke recently in a vital piece of calibration equipment used to maintain readiness aboard a U.S. Navy amphibious assault ship, it looked like the pilots and air crews were out of luck.
A guaranteed funding stream still eludes the Pentagon to develop and build an Ohio-class replacement submarine fleet for the nuclear-tipped ballistic missile boats, and it is putting the whole submarine future fleet acquisition into question.
