2 40mm MK19 Non-Lethal Short Range

3 Description: 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.

Description of telescoping case feature: Picture 1 - cartridge prior to chambering Picture 2 - cartridge chambering, case starting to telescope Picture 3 - case fully telescoped closed at the moment of firing Picture 4 - fired cartridge fully telescoped open Picture 5 - bolt recoiling with fired cartridge Blank cartridge NL Payload Cartridge

5 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 User perspective:

7 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 Non-lethality concerns including potential for eye injuries

8 Concept of Employment Firing Demonstration: Firing demonstration was 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.

9 Ten round burst at Picatinny Arsenal, August 02

10 Five round burst of multiple rubber balls: Fort Leonard Wood, MO September 2002

11 Six round interrupted burst Picatinny Arsenal May 2003

12 Summary: The 40mm MK19 Non-Lethal Short Range cartridge concept has been successfully demonstrated. Cartridge configuration adaptable to a wide variety of payloads. Initial fielding scheduled for FY06.

13 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.

17 PROGRAM STATUS: Approved for FY04 new start by the Joint Non-lethal Weapons Directorate (JNLWD). Projectile deceleration mechanism successfully demonstrated in 20mm using crude laboratory airburst mechanism. Development of an appropriate airbursting fuze or proximity fuze mechanism key to success. Market Survey published March 2003.
