Sub-Category

An asterisk precedes certain defense articles in the following list. The asterisk means that the article is deemed to be "Significant Military Equipment" to the extent specified in § 120.7 of the International Traffic in Arms Regulations (ITAR) issued by the Department of State Directorate of Defense Trade Controls (DDTC).

Sub-Category Description
a * (a) Guns over caliber .50 (12.7mm, whether towed, airborne, self-propelled, or fixed, including but not limited to, howitzers, mortars, cannons and recoilless rifles.
b (b) Flame throwers specifically designed or modified for military application.
c (c) Apparatus and devices for launching or delivering ordnance, other than those articles controlled in Category IV.
d * (d) Kinetic energy weapon systems specifically designed or modified for destruction or rendering mission-abort of a target.
e (e) Signature control materials (e.g., parasitic, structural, coatings, screening) techniques, and equipment specifically designed, developed, configured, adapted or modified to alter or reduce the signature (e.g., muzzle flash suppression, radar, infrared, visual, laser/electro-optical, acoustic) of defense articles controlled by this category.
f * (f) Engines specifically designed or modified for the self-propelled guns and howitzers in paragraph (a) of this category.
g (g) Tooling and equipment specifically designed or modified for the production of defense articles controlled by this category.
h (h) Test and evaluation equipment and test models specifically designed or modified for the articles controlled by this category. This includes but is not limited to diagnostic
i (i) Autoloading systems for electronic programming of projectile function for the defense articles controlled in this Category.
j (j) All other components, parts, accessories, attachments and associated equipment specifically designed or modified for the articles in paragraphs (a) through (i) of this category. This includes but is not limited to mounts and carriages for the articles controlled in this category.
k (k) Technical data (as defined in § 120.10 of this subchapter) and defense services (as defined in § 120.9 of this subchapter) directly related to the defense articles enumerated in paragraphs (a) through (j) of this category. Technical data directly related to the manufacture or production of any defense articles enumerated elsewhere in this category that are designated as Significant Military Equipment (SME) shall itself be designated SME.
l (l) The following interpretations explain and amplify the terms used in this category and elsewhere in this subchapter:
  • (1) The kinetic energy weapons systems in paragraph (d) of this category include but are not limited to:

    • (i) Launch systems and subsystems capable of accelerating masses larger than 0.1g to velocities in excess of 1.6km/s, in single or rapid fire modes, using methods such as: electromagnetic, electrothermal, plasma, light gas, or chemical;
    • (ii) Prime power generation, electric armor, energy storage, thermal management; conditioning, switching or fuel-handling equipment; and the electrical interfaces between power supply gun and other turret electric drive function;
    • (iii) Target acquisition, tracking fire control or damage assessment systems; and
    • (iv) Homing seeker, guidance or divert propulsion (lateral acceleration) systems for projectiles.
  • (2) The articles in this category include any end item, component, accessory, attachment part, firmware, software or system that has been designed or manufactured using technical data and defense services controlled by this category.

  • (3) The articles specifically designed or modified for military application controlled in this category include any article specifically developed, configured, or adapted for military application.
