This journey—from a small brick building to a global aviation powerhouse—shows not just corporate longevity but a century of Connecticut’s deep connection to aviation history.

From Hartford Beginnings to Global Aviation Leader

Back in 1925, Frederick Rentschler and his team set up shop in a modest brick building on Capitol Avenue in Hartford. Their early breakthrough, the R-1340 WASP engine, quickly grabbed the attention of military officials.

Early Growth and Military Partnerships

The U.S. Navy stepped in as Pratt & Whitney’s first major customer, ordering 200 engines and sparking rapid expansion. That success pushed the company to move to bigger facilities in East Hartford by 1929, which became their longtime headquarters.

During World War II, Pratt & Whitney supplied more than half of the aviation horsepower used by Allied forces. Their contribution played a huge role in the war effort and cemented their spot as a key part of America’s defense infrastructure.

Connecticut’s Economic Powerhouse

Today, Pratt & Whitney stands as one of Connecticut’s largest employers, with about 11,000 workers across the state. Most employees work at the East Hartford headquarters and the manufacturing facility in Middletown, making a big economic impact in the region.

Local Economic Impact

The company’s reach goes well beyond direct jobs. As one of the state’s top three employers, Pratt & Whitney pumps around $1 billion into the local economy each year through partnerships with more than 100 Connecticut suppliers.

This economic activity benefits communities all over the state, from New Haven to Stamford, Waterbury to New London.

Over the last decade, the company has invested more than $1 billion in its Connecticut facilities. Plans for a new 465,000-square-foot building in East Hartford show just how committed they are to staying rooted in the state.

Navigating Challenges While Maintaining Connecticut Roots

Even with its long history in Connecticut, Pratt & Whitney has faced some tough moments in labor relations. A three-week machinists’ strike in May 2025 brought worker concerns about job security into the spotlight, especially as the company invests in facilities outside the state.

Securing the Future in Connecticut

The strike ended with a new union contract that keeps operations in East Hartford and Middletown running through at least 2029. Company leaders have said again and again that Connecticut will remain Pratt & Whitney’s home for the foreseeable future, which is reassuring for workers and local communities.

“Our Connecticut heritage is inseparable from our identity,” one executive said during the centennial celebrations in Hartford. “The innovation that happens here can’t be replicated elsewhere.”

A Global Reach with Connecticut at its Core

Pratt & Whitney’s impact goes way beyond Connecticut. Right now, more than 90,000 of its engines are powering aircraft all over the world.

The company makes products like the F135 engine for F-35 fighter jets. There’s also the GTF (Geared Turbofan) for commercial planes—it’s honestly a big leap in aerospace engineering.

Pratt & Whitney still keeps its roots in Connecticut, even as it looks to the future. It started out in a brick building in Hartford, and now it’s a global aviation leader.

The company’s story is tightly woven with Connecticut, its home for a century. That partnership just keeps adapting, even as the world of aviation gets more competitive every year.
