ADVANCED TECHNOLOGY DEMONSTRATION AH-1 W Cobra Aircraft MMI Display RAMICS Munition Mk 6 Mine 30 August 2003 11
MUNITION TESTS • 20/25/30 mm used • Various nose diameters and shoulder heights/roll offs • With and without reactive payload • Successes with 25 mm and 30 mm • Munition size drives gun and visa versa • Trade study needed for determination of significant difference 30 August 2003 12
AOA SUMMARY 30 August 2003 13
GUN/MUNITION TRADE STUDY 25 mm vs. 30 mm • Constructed a Decision Analysis Worksheet described in the Defense Systems Management College (DSMC) System Engineering Management Guide, 1983, Chapter 8 - “Trade Studies. ” – Provides a disciplined, objective approach to decision making. – Applicable in situations where all candidates meet minimum performance requirements. – Allows performance parameters to be weighted, scored individually. 30 August 2003 14
TRADE STUDY RESULTS Parameter Weight Factor Effective (sink/deflagrate) Critical 25 mm G 1 R 2 30 mm NOTES: 125 mm can sink a mine at the threshold neutralization depth. If sinking is an acceptable neutralization method, then it minimally meets the performance requirement. 225 mm cannot deflagrate a mine at the threshold neutralization depth. If a mine must deflagrate in order to be considered neutralized, then the 25 mm does not meet the minimum performance requirement. LB Integratable Extremely Important G G Executable Considerabl y Important G G Operationally Available Considerabl y Important G G Safe Considerabl y Important G G Supportable Considerabl y Important G LB 25 mm Weight-Score = 152 30 mm Weight-Score = 168 Difference = 10. 3% LEGEND B LB G O R Exceeds the requirement Somewhat exceeds the requirement (objective) Meets the requirement (threshold) Almost meets the requirement Does not meet the requirement A difference in weight-scores of at least 10% indicates that there is a meaningful distinction between candidates, according to the DSMC SE Management Guide. 30 August 2003 15
CTD PHASE EXIT CRITERIA ASN RDA Acquisition Decision Memorandum 15 Mar 01 established the following C&TD Phase Exit Criteria : 1. Receive Safe Standoff certification from NAVAIR (Code 4. 1). 2. Determine projectile mine neutralization capability beyond 40 ft depth. 3. Develop a reduced-recoil gun/turret design that is acceptable for MH-60 S integration (based upon airframe fatigue and deformation, dynamic component wear, cost, crash load constraints and other issues as required) and document PMA 299/PMS 210 concurrence. Test and Evaluation Exit criteria completed by testing: • Safe standoff completed - Jul 02 • Projectile lethality completed - Oct 01 • Reduced recoil conducted - Apr 02 30 August 2003 16
Safe Standoff Tests • • Worst Case Threat Ensure Detonation Collect Shrapnel Data Use Safe Escape Modeling to determine distance for acceptable risk Distance impacts pointing resolution and accuracy! 30 August 2003 17
CRITERIA #1: SAFE STANDOFF • Completed - NAVAIR 4. 1 certification signed on 7 May 02 • Results : SSO Distances: Shallow mines 1500’ Deep mines 700’ 30 August 2003 18
NEUTRALIZATION CAPABILITY • • Conducted at West Freugh, Scotland Production Representative Munition Live and Inert MK 17 Sea Mines Simulated Mission Representative Sea Conditions • Live Fire Test and Evaluation Phase I Tests 30 August 2003 19
WEST FREUGH TESTS 30 August 2003 20
CRITERIA #2: MINE NEUTRALIZATION CAPABILITY BEYOND 40 FT DEPTH • • 30 August 2003 Completed - Documented in CSS ltr dated 12 Mar 2002 Results – 0 - 40 ft Deflagration – 40 - 150 ft Rapid sinking (less than 4 min. ) – 150 - 200 ft Slow sinking 21
REDUCED RECOIL DESIGN • Of the many issues for aircraft integration, at this point RAMICS development, recoil was biggest concern. • Vendor (Boeing/ATK) must demonstrate recoils consistently under 4000# using training/practice rounds. TP rounds have higher recoil than AP. Objective recoil load is 3000#. 30 August 2003 22
CRITERIA #3: REDUCED RECOIL GUN/TURRET DESIGN Completed – PMS-210/PMA-299 concurrence signed on 9 May 02 Results Achieved recoil reduction below 4000 lbs for armor piercing and Target Practice rounds 30 August 2003 23
C&TD SYNOPSIS • ATD program provided Ao. A and ORD inputs/program justification • Munitions experiments/tests fed trade study to determine if significant difference between 25 mm and 30 mm. Munition size drove gun decision. • SSO test results provided limits for targeting specification and exit criteria • Live Fire Phase I results provided exit criterion and verified analysis/reduced program risk. • SD&D Exit Criteria set at C&TD completion 30 August 2003 24
SD&D PHASE EXIT CRITERIA ASN RDA Acquisition Decision Memorandum 29 Jul 02 established the following SD&D Phase Exit Criteria : 1. 2. Meet ORD threshold for reacquisition and neutralization. 3. Complete a Production Readiness Review. 4.

Dispersion Demonstration • Conducted by Raufoss (MK 258 manufacturer) at Snillfjord, Norway. MK 258 Mod 1 cartridges were used against a test plate. • Water depths up to 75 feet with in air travel of approximately 300 feet. Gun alignment was slightly modified between series of shots (7 in a series) to get grouping data. Single shots only. • Quick look results indicate dispersion very tight at depth. Final report in review at CSS. 30 August 2003 29

CONCLUSION • By introducing T&E at beginning of the Systems Engineering process, several real benefits were realized: – – – Kept/Keeps Risk Manageable Saved Time (e. g. , splitting responsibilities) Avoided Costs (e. g. , munition development) Early Documentation Keeps Team Focused on Finish Line • Key was complete buy-in and participation by engineering and test experts – borderless team. Especially challenging given wide geographic area and diverse community (Sea and Air sides) 30 August 2003 36
