6. Target Acquisition/Fire Control Functionality

7. 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 Operational Concept based on team decisions with User input

10. 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. 25mm Conversion Bottom Line

11. 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 anincreased 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)” OCSW Caliber StudySummary

12. 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. **JSAAP OCSW Caliber Study dated 29 Mar 02 Trade Offs Developing a 25mm

14. Program Summary • Change is the only fact of life • We have accepted it • We are adopting to it • We are moving forward • Our mission still is: “To provide our soldiers with the best capabilities available withingiven cost and schedule” • We will succeed!
