From the maker's press release: Metal Storm, the Australian company probably best known for its 'million rounds a minute' electronic-fired gun technology, conducted live-round demonstrations of a 40mm version of its cannon integrated into the unmanned helicopter UAV, the Dragonfly DP4x. The Vertical Take-Off and Landing Dragonfly, developed by a second company, Dragonfly Pictures Inc. (DPI), weighs around 140 pounds--light enough to be carried by a couple of in-field operators, if needed. Along with the fully-electronic ballistic system from Metal Storm, the Dragonfly can carry imaging, communication, and environmental sensors useful in gathering remote intelligence. No word yet if the Dragonfly will also have cockpit space for the 12-inch or more modern 3.75-inch G.I. Joes.More information available at www.metalstorm.com.
