14. Ammunition StatusXM1019 HEAB Cartridge Status: • Design is remote settable high explosive air bursting ammunition • Fuze Status: • Baseline design established – has met ATD exit criteria • Limited safety tests completed with satisfactory results. Safe to load and assemble. • Independent power supply – point detonating/render safe

15. Ammunition StatusXM1019 HEAB Cartridge • Fuze Status (continued): • Functions demonstrated successfully: • Power up and set time-to-burst demonstrated from the weapon (single shot and automatic) and test barrel • Adjust time-to-burst based upon actual muzzle velocity demonstrated from the weapon and test barrel • Ability to derive electrical energy from the launch environment (IPS) demonstrated from the test barrel • Ability to retain launch derived firing energy over the maximum effective range (2000m) demonstrated from the test barrel. This is the render safe (RS) function needed to minimize the incidence of unexploded ordnance on the battle field. • Point detonation capability against soft target • Cumulative successes indicate we now meet the SDD exit criteria for airburst reliability with respect to initiating the front warhead. • Limited demonstration of dual warhead airburst function
