DARPA Gremlins; baby drones that return to mother

"As previously revealed by DARPA, Gremlins aims to develop fleets of 'low-cost, reusable unmanned air systems' (aka drones) that can be launched from other aircraft, perform their missions, and then return to land back aboard their motherships -- an acrobatic feat to be performed entirely midair. While Gremlins will be too small to engage in combat operations, the drones will be equipped with sensors and electronic equipment capable of performing surveillance and reconnaissance missions, and also electronic warfare -- jamming, spoofing, and otherwise frustrating opposing radar systems."

Looks interesting and useful. I think swarms of smaller, cheaper craft will be used more and more as people figure out how best to utilize them.
