>>我感兴趣，马上在线咨询Additional information about some of the technologies on the Technology Alert List is available on the TecWorld website, the Departments unclassified Intranet science and technology reference site managed by the Bureau of

Intelligence and Research. You can access TecWorld on OpenNet at http://tecworld.inr.state.gov

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

-- Fissile or special nuclear materials

-- Uranium enrichment, including gaseous diffusion,centrifuge, aerodynamic, chemical, Electromagnetic Isotopic Separation (EMIS), Laser Isotope Separation

(LIS)

-- 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) >>我感兴趣，马上在线咨询
