Title:
Magnavox Sonobuoy Transmitter
Description:
Magnavox, which opened their Fort Wayne plant in 1931, had long been participating in war production before the onset of the Cold War. During World War II, the company produced radio equipment as well as radar and sonar systems. Starting in the 1950s, Magnavox began working on Sonobuoy technology and would eventually produce millions of the underwater acoustic detection devices.

This 1970s AN/SSQ-53B Sonobuoy was developed by Magnavox as an improvement on previous models. Sonobuoys were first invented during World War II to combat the threat of German submarines, and, years later, advanced technologically in response to the increasing sophistication of Soviet subma-rines which were a threat to American and Allied shipping. Dropped by plane, Sonobuoys track the location of submarines by using acoustic sensors to detect underwater sound. They are designed to be deployed simultaneously for multiple points of data collection and then transmit the information to airplanes and ships.
