Acoustics: New British Sub Unveiled

The Telegraph (UK center-right newspaper) has an article on the unveiling of the Astute, a next generation, British Royal Navy nuclear submarine. Some of the 'factoids' mentioned in the article are very interesting - the nuclear power plant has the acoustic signature of a "torch" (British English for "flashlight"), it can detect the QE2 cruise liner leaving the harbor in New York all the way from the English Channel, and it uses a fiber optic "periscope" instead of the traditional kind. Enjoy!
