Standing Office 81

ML19.Directed Energy Weapon (DEW) systems, related or countermeasure equipment and test models, as follows, and specially designed components therefor:

List
Wassenaar Arrangement – Munitions List – WA-LIST (25) 1
a. "Laser" 'weapon systems' not specified in ML19.f.;
b. Particle beam 'weapon systems';
c. High power Radio-Frequency (RF) 'weapon systems';
d. Equipment specially designed for the detection or identification of, or defence against, systems specified in ML19.a. to ML19.c.;
e. Physical test models for the systems, equipment and components, specified in ML19.;
f. "Laser" systems specially designed to cause permanent blindness to unenhanced vision, i.e., to the naked eye or to the eye with corrective eyesight devices.
Note 1 DEW systems specified in ML19. include systems whose capability is derived from the controlled application of:
a. "Lasers" of sufficient power to effect destruction similar to the manner of conventional ammunition;
b. Particle accelerators which project a charged or neutral particle beam with destructive power;
c. High pulsed power or high average power radio frequency beam transmitters, which produce fields sufficiently intense to disable electronic circuitry at a distant target.
Note 2 ML19. includes the following when specially designed for DEW systems:
a. Prime power generation, energy storage, switching, power conditioning or fuel-handling equipment;
b. Target acquisition or tracking systems;
c. Systems capable of assessing target damage, destruction or mission-abort;
d. Beam-handling, propagation or pointing equipment;
e. Equipment with rapid beam slew capability for rapid multiple target operations;
f. Adaptive optics and phase conjugators;
g. Current injectors for negative hydrogen ion beams;
h. "Space-qualified" accelerator components;
i. Negative ion beam funnelling equipment;
j. Equipment for controlling and slewing a high energy ion beam;
k. "Space-qualified" foils for neutralising negative hydrogen isotope beams.
Technical Note
For the purposes of ML19., 'weapon systems' are designed to damage, destroy or effect mission abort of a target.
