"In 2018, the U.S. Navy hopes to take a major step toward fielding a
cyber-attack system on a tactically survivable, fighter-size
aircraft.

Although researchers are cautious about discussing their cyberwarfare
and electronic attack projects, one company states that it is
“developing a
weapon system that can deliver cyber-effects through free space into
an
aperture.”

That opaque explanation refers to a cyber-weapon, sized for a
tactical
aircraft or UAV, that can create a long-range data stream—most likely
from an active, electronically scanned array (AESA) emitter. The
emitter
will function both as radar and the source of these uniquely tailored
data
streams that could be used for electronic attack and cyber-invasion."

Systems like this are starting to blur the line between electronic
jamming
and cyberwarfare.
