En la actualidad, llamamos SONAR a cualquier sistema que, haciendo uso de las ondas de sonido que se transmiten a través del agua, pueda localizar un objeto sumergido. Este instrumento comenzó siendo conocido de una manera bien distinta. El sistema era llamado ASDIC, un nombre que se correspondía con las siglas del proyecto antisubmarino que estaban llevando a cabo los aliados (Anti-Submarine Detection Investigation Committee) al final de la Primera Guerra Mundial.

English

Subject field(s)
  • International Bodies and Committees
  • Sonar and Underwater Detection (Military)
OBS

The first device used to locate submarines is called Asdic (named after the Ati-Submarine Detection Investigation Committee) and was invented during World War I by British, American, and French Scientists. ... There is also a considerable amount of confusion about the origins of the term "ASDIC". To quote Willem Hackmann from Seek and Strike, "The Oxford University Press was prompted on 11 December 1939 to ask the Admiralty about its etymology after Churchill used the term in the House of Commons. After a certain amount of inter-departmental discussion, they were told that the word was the acronym of Allied Submarine Detection Investigation Committee. This body was formed during the war of 1914-1918, and organized much research and experimentation for the detection of submarines, however, no committee bearing this name has been found in the Admiralty archives."

Key term(s)
  • Allied Submarine Detection Investigation Committee

French

Domaine(s)
  • Organismes et comités internationaux
  • Sonar et détection sous-marine (Militaire)
OBS

L'acronyme ASDIC est souvent associé au nom anglais de la Commission commune franco-britannique de lutte anti-sous-marine (Anti-Submarine Detection and Investigation Committee), créée pendant la Première Guerre mondiale. Fait intéressant, au moins un historien spécialisé dans la lutte anti-sous-marine doute que cette commission ait réellement existé.
