The State Department maintains a Technical Alert List, also known as the
sensitive major list, to guide their evaluation of visa submission.
Sorted by rate.
CRITICAL FIELDS LIST
A. CONVENTIONAL MUNITIONS: Technologies associated with:
-- Warheads and other large caliber projectiles
-- Reactive armor and warhead defeat systems
-- Fusing and arming systems.
-- Electronic countermeasures and systems
-- New or novel explosives and formulations
-- Automated explosive detection methods and equipment
B. NUCLEAR TECHNOLOGY: Technologies associated with
production and use of nuclear material for both peaceful and military
applications. Included are technologies for:
-- Enrichment of fissile material
-- Reprocessing irradiated nuclear fuel to recover produced
plutonium
-- Production of heavy water for moderator material
-- Plutonium and tritium handling
Also, certain associated technologies related to nuclear physics and/or
nuclear engineering. Includes materials,equipment or technology associated
with:
-- Power reactors, breeder and production reactors
-- Spent fuel reprocessing, plutonium, mixed oxide nuclear research
Inertial Confinement Fusion (ICF)
-- Magnetic confinement fusion
-- Laser fusion, high power lasers, plasma,
-- Nuclear fuel fabrication including Mixed Oxide (uranium-
plutonium) fuels (MOX)
-- Heavy water production
-- Tritium production and use
-- Hardening technology
C. ROCKET SYSTEMS (including ballistic missile systems,space launch
vehicles and sounding rockets) and Unmanned Air Vehicles (UAV) (including cruise
missiles, target drones, and reconnaissance drones): Technologies associated
with rocket systems and UAV systems. The technology needed to develop a
satellite launch vehicle is virtually identical to that needed to build a
ballistic missile.
D. ROCKET SYSTEM AND UNMANNED AIR VEHICLE (UAV) SUBSYSTEMS:
Propulsion technologies include solid rocket motor stages,and liquid
propellant engines. Other critical subsystems include re-entry vehicles,
guidance sets, thrust vector controls and warhead safing, arming and fusing.
Many of these technologies are dual-use. Technologies include:
-- Liquid and solid rocket propulsion systems
-- Missile propulsion and systems integration
-- Individual rocket stages or staging/separation mechanism
-- Aerospace thermal (such as superalloys) and high-performance
structures
-- Propulsion systems test facilities
E. NAVIGATION, AVIONICS AND FLIGHT CONTROL USEABLE IN ROCKET SYSTEMS AND
UNMANNED AIR VEHICLES (UAV): These capabilities directly determine the delivery
accuracy and lethality of both unguided and guided weapons. The long-term costs
to design, build and apply these technologies have been a limiting proliferation
factor. Technologies include those associated with:
-- Internal navigation systems
-- Tracking and terminal homing devices
-- Accelerometers and gyroscopes
-- Rocket and UAV and flight control systems.
-- Global Positioning System (GPS)
F. CHEMICAL, BIOTECHNOLOGY AND BIOMEDICAL ENGINEERING: The technology used
to produce chemical and biological weapons is inherently dual-use. The same
technologies that could be applied to develop and produce chemical and
biological weapons are used widely by civilian research laboratories and
industry; these technologies are relatively common in many countries. Advanced
biotechnology has the potential to support biological weapons research. In the
biological area, look for interest in technologies associated
with:
