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.
Late 1913
There is mention of this equipment in a Weekly Order, naming 14 ships whose names are to be struck from an Admiralty Letter of 16 July 1913.[2]
A later order lists those ships containing the equipment, imploring them to contact the manufacturer so the machines can receive maintenance.
