The Navy is in the process of replacing old EA-6B Prowlers with new EA-18G Growlers (a electronic warfare version of the Super Hornet).
Via Wired’s Danger Room blog:
The frontline weapon for this electronic war is a new airborne jamming system currently in development. The Next Generation Jammer should allow the Navy to blind the enemy’s radars, disrupt its communications and slip malicious code into computer networks.
Besides radar-jamming, the NGJ should allow the Navy to disable remotely detonated, improvised explosive devices — something the EA-6B already does — as well as insert viruses into command networks, a tactic Israel allegedly first used in combat during its 2007 air attacks on a suspected Syrian nuke site.
