MIT’s AeroAstro labs is working on a special rocket drone that can fly up to Mach 0.8 (614 mph) and it is called the Firefly. The zeppelin-shaped mini-rocket is designed to be launched from a fighter jet to collect data or distract enemy weapons systems.
The Firefly is designed in response to a challenge presented by the U.S. Air Force. The assignment was as follows: develop an unmanned aerial vehicle (UAV) no more than 2.5 inches wide and 17 inches long that can be launched mid-air from a fighter jet and that can fly at Mach 0.8 for 2 to 5 minutes. MIT had been successful in the past designing the Peredix swarming drones so they were up for the challenge.
