**Annex Item No. vii**
(vii) *Sensitivity of Technology:*
1. The GBU-53/B Small Diameter Bomb-Increment II (SDB-II) is a 250-pound class precision-guided, semiautonomous, conventional, air-to-ground munition used to defeat moving targets from standoff range. The SDB-II has deployable wings and fins and uses Global Positioning System/Inertial Navigation System (GPS/INS) guidance enabled by Selective Availability Anti-Spoofing Module (SAASM) or M-Code, network-enabled datalink (Link-16 and ultra-high frequency), and a multi-mode seeker (millimeter wave radar, imaging infrared, semi-active laser) to autonomously search, acquire, track, and defeat a variety of moving or stationary targets, at standoff range or close in, in a variety of attack modes, in clear or adverse weather. The SDB-II employs a multi-effects warhead (blast, fragmentation, and shaped-charge) for maximum lethality against armored and soft targets. The SDB-II weapon system consists of the tactical All-Up-Round (AUR) weapon, a 4-place common carriage system, and Mission Planning System Munitions Application Program (MAP).
The SDB-II Weapon Load Crew Trainer (WLCT) is a mass mockup of the tactical AUR used for load crew and maintenance training. It does not contain energetics, a live fuze, any sensitive components, or hazardous material. It is not flight certified.
2. The highest level of classification of defense articles, components, and services included in this potential sale is SECRET.
3. If a technologically advanced adversary were to obtain knowledge of the specific hardware and software elements, the information could be used to develop countermeasures that might reduce weapon system effectiveness or be used in the development of a system with similar or advanced capabilities.
4. A determination has been made that Belgium can provide substantially the same degree of protection for the sensitive technology being released as the U.S. Government. This sale is necessary in furtherance of the U.S. foreign policy and national security objectives outlined in the Policy Justification.
5. All defense articles and services listed in this transmittal have been authorized for release and export to the Government of Belgium.
