From The Dreadnought Project
Jump to navigationJump to search
Submarine Sound Signalling was an experimental means of communication at sea trialled around 1911.
An Admiralty letter dated 11 October 1911 names some 30-50 ships to be fitted with apparatus from the American company, Gardner's or Lieutenant Hervey's design.[1]
Coincidence
The building bearing the name "American Submarine Sound Signaling" sits prominently in Boston between North Station and the USS Constitution, where the editor had long wondered what it was referring to before discovering it was in his sphere of interest.
