A tactical sonar system for transmitting submarine activity, the sonobuoy is a core technology for anti-submarine warfare. Sparton manufactures both active (emitting sound energy into the water and waiting for a return transmission) and passive (purely listening for sound wave transmissions) sonobuoys.

With over 6 million sonobuoys deployed to the United States and foreign* customers over the past 60 years, Sparton continues to serve as a vital supplier to these militaries with the most effective anti-submarine warfare sensor capability.

U.S. Specification Sonobuoys are sold through ERAPSCO, a joint venture between Sparton Corporation and Ultra Electronics – USSI.

Sonobuoy TechSystems operates under ERAPSCO for all ITAR-approved international sales and technical support.

*Foreign sales are subject to the International Traffic in Arms Regulations (ITAR), and must be approved by the state department.
