General Atomics marks second expansion in four months in Shannon

Jackson, Miss. (Sept. 10, 2026) – General Atomics is expanding once again in Shannon, continuing a long track record of investment in Lee County. The project represents a corporate investment of $87 million and will create 125 jobs.

General Atomics Electromagnetic Systems supports defense, government and national security customers through the development and manufacturing of advanced technologies that address critical mission needs. The project includes the construction of a new 200,000-square-foot manufacturing facility that will expand production capabilities for the company’s advanced weapons systems including Vektrex™, a maneuvering 155mm precision-guided munition designed to extend the range and effectiveness of artillery forces and other precision-strike programs.

In March, General Atomics announced a $25 million investment to update and expand its advanced weapons production line with new, fully automated computer numerical control machines.

The Mississippi Development Authority is providing assistance with site preparation and construction costs along with support through the Mississippi Flexible Tax Incentive, or MFLEX, program. Lee County also is assisting with the project.

Headquartered in San Diego, General Atomics manufactures and develops innovative technologies to create breakthrough solutions supporting operational environments from undersea to space. The company established its Electromagnetic Systems Group Manufacturing Center of Excellence in Shannon in 2005.

The project is expected to be completed in 2028.
