Project Artemis (original) (raw)

Project Artemis was a United States Navy acoustics research and development experiment from the late 1950s into the mid 1960s to test a potential low-frequency active sonar system for ocean surveillance. The at sea testing began in 1960 after research and development in the late 1950s. The project's test requirement was to prove detection of a submerged submarine at 500 nmi (580 mi; 930 km). The experiment, covering a number of years, involved a large active element and a massive receiver array.
