OVERVIEW • The Situation • The Requirement • Terms of Reference • Technology • - Guns • - Ammo • Target Vulnerability • Tactical Application
The Situation • The Fluid Battle Environment • Organized Military Opposition • Unconventional Warfare • Civil Unrest • Non Combatant Screens • Dynamic Rules of Engagement • Currently Limited Response Options • Water Cannons • Sponge Balls • “Rubber” Bullets • Etc.
The Requirement • A Multi Purpose Weapon with Scaleable Lethality • Near instant Scalability from Lethal to Non Lethal and Back • Readily Deployed • Minimum Logistical Tail • Potential for various ammo types: ABM,HE,APDS
NATO Policy Less Than LethalWeapons (LTLW) • Incapacitate or repel personnel, with a low probability of fatality • Expand the range of options available to NATO Military Authorities. • LTLW shall not be required to have zero probability of causing fatalities or permanent injuries.
Design Elements of a Scaleable Kinetic Energy Weapon • Predictable delivery of subprojectiles requires: • MV Correction - Minimize error in range • Accurate Fuzing - Precise distance from the target • Uniformity of the payload - Subprojectiles same size • Uniformity of payload distribution - area coverage
Payload: Subprojectiles 35mm Technology Suite
35mm Air Burst Munition Kinetic Energy Time Fuze (ABM-KETF) – Layout: Note: The payload (500g) is composed of cylindrical W-Subprojectiles (here 3.3 g). For engagements other than AA (e.g. G-to-G) the mass of the subprojectiles can be reduced accordingly (e.g. 1 to 1.5 g)
35 mm ABM (Ahead) Subprojectile Dynamic Parameters Subprojectile Density Valid for 3.3 g Subprojectiles
35 mm Air Burst MunitionVarious Payload Arrangements, e.g: Air Defense Version (Ahead) IFV Version 35 mm Caliber SP-diameter: 4.65 mm 11 Layers @ 31 SP (341) of 1.5 g each Subprojectile, SP-diameter: 5.85 mm 8 Layers @ 19 SP (152) of 3.3 g each F2 15201 BB
Payload Foot-Print 35 mm ABM (Ahead): 152 subprojectiles of 3.3 g 35 mm ABM: 341 subprojectiles of 1.5 g

Target Vulnerability Criteria (>90%) In a Ground-to-Ground Defense Role(Subprojectile size 3.3gr)
35 mm Ahead Payload Ejection at 2 km Range: Performance Case: 3.3 g Subprojectiles
Tactical Scenarios Using ABM Point Target (incl. ATGW-Bunker, Prone & Covered Troops, MBT, Helicopter): Area Target (Diffused Targets): Gun Linear Target (e.g. road with vehicles): Pre-Determined Air Space (e.g. swarm of helicopters): Road F2 15081 FF
Air Burst Coverage Effectiveness Eg: 35mm Ahead with 3.3g Subprojectiles
Ahead Payload Growth Potential • Traditional Payload Effects: • Mechanical effects based on KE (Frags / Subprojectiles) • Flash & Bang • Emerging Payload Effects: • Disabling passive effects (against target sensors): Chaff, Phosphor, ... • EM waves effects (against target electronic system): NNEMP: Non-Nuclear EMP, HPM: Hyper Power Microwave, UWB: Ultra Wide Band, ... in directional radiation pattern F2 16337 BD
Summary • Military gun systems can extend their mission capabilities from lethal through near lethal to less-than-lethal. • Demonstrated technology exists that can be applied in the development of direct fire weapons systems. • The vulnerability of a broad range of targets can be accommodated within the mission profile.
