  I. MATERIALS TECHNOLOGY: The metallic, ceramic and

  composite materials are primarily related to structural

  functions in aircraft, spacecraft, missiles, undersea

  vehicles, and propulsion devices. Polymers provide seals

  and sealants for containment of identified fluids and

  lubricants for various vehicles and devices. High density

  graphite is used in missile nosetips, jet vanes and nozzle

  throats. Selected specialty materials (i.e., stealth and

  the performance of these materials) provide critical

  capabilities that exploit electromagnetic absorption,

  magnetic, or superconductivity characteristics. These

  technologies are associated with:

  - Advanced metals and alloys

  - Non-composite ceramic materials

  - Ceramic, cermet, organic and carbon materials

  - Polymeric materials

  - Synthetics fluids

  - Hot isostatic

  - Densifications

  - Intermetallic

  - Organometals

  - Liquid and solid lubricant

  - Magnetic metals and superconductive conductors

  J. INFORMATION SECURITY: Technologies associated with

  cryptography and cryptographic systems to ensure secrecy

  for communications, video, data and related software.
