Operational Concept

• Largely menu driven TA/FC with limited switches
  for weight savings
• Dual aimpoint approach battlesight always
  present
• Dot for laser aimpoint
• Open cross for HE battlesight and adjusted
  aimpoint
• Open cross with dot for KE battlesight
• Laser range finder activated upon lase switch
  press

Operational Concept based on team decisions with

25mm Conversion Bottom Line

• Mar 03 Decision to convert from 20mm to 25mm.
• Decision based on
• 25mm XM25 system technically achievable.
• Greater lethality of 25mm.
• Significant cost avoidance for 25mm airburst
  ammunition.
• May 03 Decision to Combine Low Velocity (XM25)
  and High Velocity (XM307) development efforts.
• GDATP and ATK agreed to teaming for common ammo.
• GDATP has the lead.

OCSW Caliber StudySummary

• JSAAP OCSW Caliber Study dated 29 Mar 02
• A common projectile is feasible. The 25mm
  projectile, with unique propellant cartridges for
  each system, could be developed. Production cost
  savings could easily overshadow the cost savings
  predicted in this study. This course of action
  trades greater lethality and flexibility with an
  increased weight burden.
• A common fuze, regardless of caliber, is
  feasible. A common projectile could be developed
  that would incorporate contact fuze setting and
  electronic range determination (with muzzle
  velocity correction capability)

Trade Offs Developing a 25mm

• Gains
• Increased lethality.
• Permits the leveraging of funds from both XM29
  and XM307 programs to improve the 25mm in terms
  of aeroballistics and warhead/fuze efficiency.
• Significant savings in development and production
  cost of ammunition estimated at 109.6M
  (potentially higher)
• Provides an opportunity to develop a relative
  single family of 25mm munitions for XM25 and
  XM307.
• Losses
• Increased weight of XM25 makes XM29 combinatorial
  system weight (KPP) unachievable at this time.
• Depending on acquisition approach, could required
  additional RDTE funding and increase in schedule.
