Sonar
Sonar (originally an acronym for SOund Navigation And Ranging) is a technique that uses sound propagation (usually underwater, as in Submarine navigation) to navigate, communicate with or detect other vessels. Two types of technology share the name "sonar": passive sonar is essentially listening for the sound made by vessels; active sonar is emitting pulses of sounds and listening for echoes. Sonar may be used as a means of acoustic location and of measurement of the echo characteristics of "targets" in the water. Acoustic location in air was used before the introduction of radar. Sonar may also be used in air for robot navigation, and SODAR (an upward looking in-air sonar) is used for atmospheric investigations. The term sonar is also used for the equipment used to generate and receive the sound. The acoustic frequencies used in sonar systems vary from very low (infrasonic) to extremely high (ultrasonic). The study of underwater sound is known as underwater acoustics or hydroacoustics.
Adding as a note the US military have a LOT of people already trained in the use and operation of any of the equipment this weapon may use
Sonar Technician
Sonar Technician (abbreviated as ST) is a United States Navy occupational rating.
SoM - Soundman: Pay grades 2c and 3c established 1942; pay grades C and 1c established 1943;
SoMH - Soundman (Harbor Defense)
SO - Sonarman: 1943-1964; SOG - Sonarman (Sonar); SOH - Sonarman (Harbor Defense)
ST- Sonar Technician: 1964–present; STG- Sonar Technician (Surface); STS- Sonar Technician (Submarine)
ST's are responsible for underwater surveillance. They assist in safe navigation and aid in search, rescue and attack operations. They operate and repair sonar equipment. ST's track underwater threats and send tracks to fire control (antisubmarine warfare controlling station) operator (ASWCS)for further evaluation and or destruction.
The can operate, repair, rebuild, and defend the same weapon you describe.. All the prerequirements are there...
The Men
The Power
The Equipment....
So yes, it is more a matter of time not if
