  Objective:  The objective of this effort is to develop a replacement material that can be used in all, or most, obsurant smoke cartridges currently in the USMC inventory.
  Description:  Find a material or combination of materials that, is capable of generating large quantities of obscuring smoke, while limiting the user to harmful and hazardous chemicals, both during opearation and storage.

  PHASE I: Find potential candidate materials to replace red phosphorus in smoke producing, obscurance, munitions. Define the mechanism of operation, and perform small scale tests to demonstrate its potential effectiveness and to justify larger scale testing.
  PHASE II: Using the best candidate(s) from Phase I, perform larger scale testing on prototype hardware, that demonstrates the material's smoke producing capabilities. Perform chemical analyses during operation and storage to demonstrate it does not subject the user to harmful or hazardous chemicals. Define the manufacturability of the material.

  PHASE III: The USMC has requirements for obscuring smoke producing cartridges is all mortar and artillery systems 60MM and larger. The candidate fill material has potential applications in the USMC 60MM, 81MM, and 120MM mortars; the 155MM artillery smoke cartridges; and floating smoke pot, as well as the US Army 105MM artillery cartridge. PRIVATE SECTOR COMMERCIAL POTENTIAL/

  DUAL-USE APPLICATIONS: Non-toxic smoke generation for potential use in firefighter training and entertainment, such as stage plays and celebrations.

Questions and Answers:
Q: Is the focus of the application of this material to obscuration of visible light or must the material also effectively obscure Infra-red radiation? If so, what range of wavelengths should be covered by the proposed technology?
A: Requirement for IR obscuration:
"shall generate Infra-Red (IR) screen duration, in the 0.7 to 5 and 8 to 14 micrometer (micron) band that shall be no less than 20 seconds, in a cross wind maximum of 5 miles per hour".
