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

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

12
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.

40mm MK19 Non-Lethal Long Range

• 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

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.
