Hazards of Electromagnetic Radiation to Ordnance (HERO) safe electric primers for 30mmx113mm Ammunition
Abstract
30mm x 113mm is used on the Apache (AH64) and Blackhawk (MH60) systems, its primers are not HERO safe. The primers do not meet the requirements of MIL-STD-464A. Consequently 30mm x 113mm ammunition cannot be safely handled, including loading the systems, when in high energy electromagnetic environments such as on or near Navy ships. It also introduces risk to the systems operating in unknown environments because there are approximately 10 exposed cartridges in the feed shoot between the Helicopter Body and the gun. Effort will address this design shortcoming by developing and proving out a laser initiated primer which will be a direct replacement of the existing primer. Performance of the end items will not be affected by this change.
