NATO Policy
Less Than Lethal Weapons
(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

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)

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: NonNuclear EMP, HPM: Hyper Power Microwave, UWB: Ultra Wide Band,
... in directional radiation pattern

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.
