Now here's a question. Why are we still putting so much insistence on sonobuoys when things are moving along quickly with new technology. See link:
Asia Times Online :: China News, China Business News, Taiwan and Hong Kong News and Business.
Is it just possible that we cancelled MRA4 because the sonobuoy is about to be rendered obsolete? It might also explain why the US were happy to take MAD off of their P8s?
I'm no ASW expert, but sonobuoys are a pretty old idea and surely we have been a little more inventive in recent years.
