The Heligun was developed by Hughes Aircraft as part of a complete package for the OV-6 recon helicopter. It offered a number of significant advantages over the Minigun – it was half the weight, self-powered (not electrically driven), and had a mind-boggling 6000RPM firing rate. Ultimately, it was not adopted because the reliability (mean time between stoppages) couldn’t quite be brought up to par, and Army officials decided that it didn’t offer enough improvement over the already adopted M134 Minigun to be worth the switch.
