Encapsulation and Delivery of Non-Lethal Malodorant in a 40mm-munition or Hand-thrown Grenade



ACQUISITION PROGRAM: Joint Non-Lethal Weapons Program; (ACAT IV)

OBJECTIVE:  To develop a non-lethal malodorant weapon which can be dispersed from a 40mm delivered munition (fired from standard 40mm launcher) or a hand-thrown munition.  Malodorous payloads must be effective at repelling humans, while being maintained at concentrations that do not trigger trigeminal nerve activation.  Above the concentration threshold of trigeminal nerve activation, chemicals must be classified as Riot Control Agents per the Chemical Weapons Convention.

DESCRIPTION:  The Department of Defense (DoD) has developed and tested a malodorant payload, potentially capable of repelling humans at concentrations that do not cause trigeminal nerve activation.  Previous attempts to seal this payload into a tactical form-factor, such as a hand-thrown grenade or 40mm-muntion have not been successful as the chemical composition is highly volatile.  A malodorant weapon could therefore be created by two means: 1) Developing a sealing or encapsulation technique capable of preventing leaks of the government developed malodorous payload 2) Developing a new malodorous payload. 

PHASE I:  If a new payload is proposed, develop and submit IRB protocols for two sequential experiments.  The first will use a lateralization test to determine the threshold at which trigeminal nerve activation occurs.  The second will determine the effectiveness at repelling human subjects from an area at concentrations below the established threshold.  Perform these two tests.

If it is proposed to use the government developed malodorous payload, develop and submit an IRB protocol to determine the effectiveness at repelling human subjects from an area at concentrations below the established threshold.  Perform this test.

Using the results of these tests, determine the feasibility of using malodorants to remove individuals from enclosed spaces.  Estimate the number of munitions required t0 generate effective concentrations in an enclosed 5m x 5m x 3m space.

PHASE II:  Develop and demonstrate an initial prototype of a malodorant munition that does not leak payload despite the shock expected from transportation and handling in military environments.  Show concentration measurements as a function of time and area/volume denied.

PHASE III:  Develop and test a mature prototype in a relevant military environment.  Demonstrate effectiveness against highly and lightly motivated personnel.

PRIVATE SECTOR COMMERCIAL POTENTIAL/DUAL-USE APPLICATIONS:  This technology could be used by any branch of the military or by civilian forces to deny, move, or suppress personnel.
