Partial Verification of Novel ASW Concept 4 Years Later by McDonalds

"Imitation is the sincerest form of flattery." - Charles Caleb Colton (1780–1832)


2008 - Novel Approach to Anti-Submarine Warfare - AUNs

The latest ASW concept, still under wraps and unprototyped, is expected to be a quantum leap over existing ASW techniques. M.E. guessed (2008) either the U.K. or U.S. was leading this novel effort:

"The latest concept involves a combination of nanotechnology and biomolecular chemistry. Once a submerged submarine has been coated with an invisible attractant by simply traveling through a deposit place en route to somewhere predictable (e'g. homeport), the trap has been set....Up to months later, when and if the submarine visits a so-called registration region, millions of nanoscale AUNs would be attracted by the sub's invisible coating and attach chemically to its outer hull "

Apparently, the concept development has recently progressed to commercial use in the U.K.:

2012 - McDonalds to use new anti-theft spray - DNA

"McDONALD'S restaurants are fighting back against thieves by blasting suspected robbers with an invisible DNA spray as they attempt to flee.... Developed in the United Kingdom by a police officer and a chemist, the spray has been used by McDonald's outlets in Britain and Europe.... The solution is invisible to the naked eye and unique to each location. It stays on clothing for up to six months and on skin for up to two weeks."

Submarines are always silent and strange.
