Connecticut is Leading the Way in Advanced Manufacturing
Connecticut is home to manufacturing pioneers — from multinational OEMs to leading suppliers of components, composites, and related services of all types. Together, they form one of America’s most successful and forward-thinking advanced manufacturing ecosystems — powering today’s advances and innovation in precision processes, breakthrough fabrications, and patented products.
More than 4,400 manufacturing establishments are located in Connecticut1, employing over 156,000 people2 and generating nearly 11% of the state's total GSP3 (gross state product). Connecticut has the 7th highest proportion of STEM-related fields and jobs in the U.S.4, with this skilled workforce driving some of the densest advanced manufacturing concentrations in the country in Groton-New London — ranked one of the top 10 manufacturing hubs in the nation5 — Stratford, and East Hartford6.
“I’ve run businesses for Lockheed Martin in a number of states including Florida and New Jersey and Maryland, and Connecticut has been the most friendly state. Flat out, we’ve had the most communication with the political establishment, the governor and the senators.”
— Paul Lemmo, Head of Lockheed Martin IWSS
Connecticut’s manufacturing prowess is rooted in its aerospace and defense industry, with thousands of supply chain and component firms supporting the production of jet engines, helicopters, and nuclear submarines among others. The skilled manufacturing and engineering talent concentrated in the area has driven the state to the forefront of medical device, semiconductor machinery, hydrogen fuel cell, laser cutting, and other precision manufacturing.
