This weekend, I caught up on a stack of journals piling up on my stairwell (some were from 2009 ... ). I found an interesting tidbit in the June 2011 Proceedings that talks about the Army's M-56 Coyote that can deliver three types of obscurants: visual, infrared (IR), and radio frequency (RF). The RF component covers the bands used by virtually all current and likely future anti-ship missiles, using a carbon aerosol-fiber.
A few months earlier, in contemplating how we might break the DF-21 kill chain, I speculated about using a chaff-like substance that could hide a carrier from an incoming ballistic missile. Apparently, the Army has something like that. It would be nice if the Navy could adopt it, it seems.
Huh. Never heard of this place. See the article itself starting on page 58.
