40mm MK19 Non-Lethal Short Range

The MK19 Non-Lethal Short Range cartridge uses a telescoping cartridge case to provide weapon powering while launching non-lethal payloads.

A variety of candidate payloads have been demonstrated, with multiple rubber balls being the leading candidate for initial fielding.

User perspective:

“In my own experiences, a MK-19 with NL Capabilities would provide tremendous overwatch and capability to push back a violent crowd as opposed to just engage a single agitator.

.... If the MK-19 in the foreground had NL Munitions, they would have been able to clear the crowd and re-open the bridge behind them.

….In cities and villages, a MK-19 could be extremely helpful in the event that you have a massive crowd of non-combatants who are being exploited by agitators and violent handlers to neutralize your position or deny necessary access.”

--LTC Jim Brown


40mm MK19 Non-Lethal Short Range

  • Preliminary performance requirements:

  • Minimum engagement range of 10 meters

  • Maximum effective range of 50 meters

  • Weapon cyclic rate 275 shots per minute

  • Other considerations:

  • No weapon modifications required

  • Trajectory compatible with weapon sights

Concept of Employment Firing Demonstration:

Conducted at Fort Leonard Wood on 25 SEP 2002

Representatives from the various services

witnessed the demonstration, including BG

Curry, Commandant, US Army Military Police

School; COL Lamb, Assistant Commandant;

COL Karcher, Director of the Joint Non-Lethal

Weapons Directorate; and senior NCOs from

the various services.

Mk19 non lethal short range fy04 progress continued
MK19 Non-Lethal Short Range FY04 Progress (continued)

  • Focused primarily on maturing the cartridge design to make it ready for production

  • Design improvements address reliability, producibility, corrosion resistance, waterproofness, etc.

  • Volumetric propellant loaders fabricated to eliminate weighing propellant charges

  • Crimping tooling being instrumented to monitor crimp process during cartridge assembly

  • Modeling and simulation effort underway to support future production and to identify potential problems


MK19 Non-Lethal Short Range Summary:

  • The 40mm MK19 Non-Lethal Short Range cartridge concept has been successfully demonstrated

  • Cartridge configuration adaptable to a wide variety of payloads

  • Cartridge configuration is rapidly maturing into the production configuration

  • Type Classification Standard scheduled for FY06.

  • Fourth patent pending


40mm MK19 Non-Lethal Long Range

Description:

Provides MK19 non-lethal capability with 50 to 1500 meter effective range. Uses “Davis Projectile” concept with airburst or proximity fuze to decelerate projectile at target location. Dispenses non-lethal payloads such as rubber balls. Uses conventional cartridge case and ammunition impulse to power the weapon mechanism for rapid-fire.

  • Leverages projectile deceleration mechanism developed for the 20 and 25mm Airbursting Non-Lethal Munition

  • 20mm and 25mm experiments have verified projectile deceleration mechanism works for the projectile velocities of interest

900 149 -66

1000 141 -74

Note: Residual velocity may be adjusted by altering the burst charge or payload mass. 40mm MK19 application is very similar.

MK19 Non-Lethal Long Range Status:

  • Approved for FY04 new start by the Joint Non-lethal Weapons Directorate (JNLWD).

  • Projectile deceleration mechanism successfully demonstrated in 20mm and 25mm using crude laboratory airburst mechanisms.

  • US Patent 6,7,22,283 issued April 20, 2004

  • First adjustable burst distance non-lethal projectile using an electronic fuze to be demonstrated in 25mm in September 2004 as part of the Airbursting Non-Lethal Munition program.

  • Development of an appropriate airbursting fuze or proximity fuze mechanism is the key to success.
