The Indian Head Division of the Naval Surface Warfare Center, (a branch of the Naval Sea Systems Command or NAVSEA), described in 1999 as the "national center for energetics", "the only reliable source of aluminum nanopowders in the United States” and in 2008 as "probably the most prominent US center for nano-thermite technology", alleges via Freedom of Information Act replies that records "regarding research and development of nano-sized or Ultra Fine Grained (UFG) aluminum powders, nano-sized or Ultra Fine Grained (UFG) iron oxide powders or other metal oxide powders and Metastable Intermolecular Composites prior to 2002" do not exist. According to Indian Head, "research may have been conducted by Indian Head Division personnel but not submitted."
Records prior to 2002 of Indian Head's private sector partnerships regarding nano-sized energetic materials development and production, were reportedly destroyed per policy after seven years (or all such records prior to 2002).
Explosive, unreacted thermitic material containing nano-meter sized grains of intimately mixed aluminum and iron oxide, has recently been discovered in dust created by the collapses of the World Trade Center buildings on September 11, 2001.
Evidence prior to 2002 of Indian Head's private sector partnerships regarding nano-sized energetic materials development and production exists.
"FY01 Technology Transfer Business Plan: IHDIV is considered the Navy’s Center of Excellence for Energetics development and has extensive expertise, capabilities, and information in energetics synthesis, formulation, and processing as well as in testing of energetic systems. IHDIV will transfer their knowledge of development and manufacturing energetics with respect to the use of TECHNANOGY produced nanoaluminum and supply TECHNANOGY with test data associated with the testing of TECHNANOGY nanoaluminum. TECHNANOGY is a leader in the production of nanoaluminum for use in energetic systems utilized for DoD purposes. To our knowledge, TECHNANOGY is the sole supplier of nanoaluminum for use in pilot scale processing. TECHNANOGY will share their material and knowledge of nanoaluminum processing subject to the terms and conditions of this CRADA. (cooperative research and development agreement)."
