"I want to thank Bob Leduc for his extraordinary service during his 40-year career at United Technologies," said UTC Chairman & CEO Greg Hayes. "Bob has played a significant role in shaping Pratt & Whitney as we know it today. He transformed the engine company by driving excellence and empowerment throughout the organization while most recently leading its 40,000 employees through the entry into service of the GTF, F135 and PW800 programs. Bob is one of the most esteemed leaders in aerospace and will leave a lasting imprint on Pratt & Whitney."

Chris Calio will assume leadership of Pratt & Whitney after serving as president of its commercial engines business since 2017.

"Chris and Bob will work closely together over the next few months to ensure a smooth transition for both our customers and employees," said Hayes. "Chris has a proven record of performance and his commitment to customers, innovation and growth will position Pratt & Whitney to win for many years to come."

As president of Pratt & Whitney's commercial engines business, Calio is responsible for the development, program management, sales, customer support and aftermarket services of the company's portfolio of large commercial engines, including the P&W GTF engine family.

Previously, Calio served as chief of staff to UTC Chairman and CEO Greg Hayes. He joined United Technologies in 2005 and served in positions of increasing responsibility across the corporation. He holds a bachelor's degree in political science from Trinity College, and MBA and law degrees from the University of Connecticut.
