capable of: Launch @ 100,000 Gs Power and set in feed system Two-way communication @ full automatic firing (250 shots/minute) Capacitor power > 2000m (10 sec. flight) Precision airburst < 2m SD High operational reliability

Ammunition ATD Accomplishments

May 11, 2004 12


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

May 11, 2004 14


Ammunition Status TP Cartridge

Status

Fully developed to ATD requirements

Over 20k rounds built and fired to date

Demonstrated Mann barrel dispersion of .25 mils

Plan

Optimization of projectile planned for SDD

Updated design will be a ballistic match to the XM1049 AP

Cartridge

Facilities will be established for high rate production during SDD

SDD production currently planned at 210,000

May 11, 2004 15


Ammunition Status XM1019 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

May 11, 2004 16


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

Common Close Support Weapon (CCSW) Weapons Trade Study

Study found XM307 not best in any one category but

selected as weapon of choice w/ all aspects considered

XM307/XM307K50 (XM312) amongst lightest weight and

smallest volume

XM307 amongst most lethal

XM307 rated low risk w/ XM307K50 (XM312) and

off-the-shelf ammunition as fallback
