TTM opens $130 million East Syracuse plant, adding 400 jobs

TTM Technologies has opened a $130 million East Syracuse plant that county and state officials are counting on to add up to 400 jobs and deepen Onondaga County’s place in the defense supply chain. The 215,000-square-foot facility sits on about 23 acres next to TTM’s existing campus in the Town of DeWitt and is built to make Ultra-HDI printed circuit boards and advanced packaging for radar, missile defense, space and autonomous systems.

The project is one of the first in the nation purpose-built for that kind of production, a niche that TTM and state officials say has become a strategic weakness in the U.S. defense industrial base. TTM says domestic production of Ultra-HDI PCBs has been severely limited, while much of the global manufacturing has been concentrated in Asia. The new plant is meant to narrow that gap by adding U.S.-based capacity for military and other defense applications.

TTM says it is investing up to $130 million in the facility, including $30 million from the Department of War. The company says the expansion will create up to 400 new engineering and manufacturing jobs and raise its Central New York workforce to about 1,000 employees. Governor Kathy Hochul said the project strengthens the regional economy and national security, while Empire State Development President and CEO Hope Knight said it reinforces New York’s leadership in semiconductors and advanced manufacturing.

The opening on June 22, 2026, marked the latest step in a project that TTM first publicly highlighted at a beam-signing ceremony on Oct. 4, 2024, when the company said it expected to invest up to $130 million and create 400 jobs. Onondaga County Executive J. Ryan McMahon spoke at the opening, underscoring the local stakes for East Syracuse, DeWitt and the wider Syracuse economy.

TTM says it has maintained a presence in the Syracuse area for more than 60 years. The real test now is whether the company delivers the promised hiring, builds out the engineering bench it has projected, and turns the DeWitt campus into a durable hub for defense manufacturing in Central New York.
