Ammunition ATD Accomplishments

• All ATD exit criteria achieved
• Development by Kaman-Dayron of a survivable Safe
  Arm.
• Development by GD-OTS of a fuze electronics
  package capable of
• Launch _at_ 100,000 Gs.
• Power and set in feed system.
• Two-way communication _at_ full automatic firing
  (250 shots/minute).
• Capacitor power gt 2000m (10 sec. Flight ).
• Precision airburst lt 2m SD
• High operational reliability.
• Development of a passive Muzzle Velocity
  Correction (MVC) device when coupled with
  electronics - yields precision airburst.
• Development under MANTECH of a two (2) step
  Blank, Cup and Draw (BCD) process for fragmenting
  warheads.
• Development by GD-OTS of a functional link.

  bursting ammunition
• Fuze Status
• Baseline design established has met ATD exit
  criteria

  detonating/render safe

15
Ammunition Status XM1019 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
