Sparton Corp. and a partner have landed a $181.8 million contract from the U.S. Navy.

ERAPSCO, the joint venture of Sparton and USSI, is being hired to produce more than 100,000 sonobuoys, electronic devices that are used in anti-submarine warfare. 

The contract is supposed to be completed in September 2025. Most of the work, 54 percent, will be done at Sparton’s plant in DeLeon Springs. The balance of the work will be done at USSI’s facility in Columbia City, Indiana.

A job-listing website, www.Indeed.com, reports Sparton has approximately 600 employees at its DeLeon Springs plant.

The sonobuoys will be used by the U.S. Navy and foreign military customers, according to the Department of Defense.

ERAPSCO is an acronym for Expendable Reliable Acoustic Path Sonobuoy Co.
