IAE International Aero Engines (IAE)—a global consortium consisting of Japanese Aero Engines Corporation (JAEC), MTU Aero Engines AG (MTU), and Pratt & Whitney—has reaffirmed its long-standing commitment to the partnership. Together, the companies will continue advancing the technologies required to develop the next generation of highly efficient GTF engine solutions for future commercial aircraft.

“For more than four decades, IAE has benefited from a strong and enduring partnership, delivering and supporting two of the most significant commercial engine programs ever produced: the V2500 and GTF,” said JAEC Chairman Tsugio Mitsuoka.

“The GTF has brought breakthrough improvements in fuel efficiency and noise reduction. Building on that success, and with the evolution of the GTF Advantage, it provides the ideal foundation as the industry moves toward powerplant solutions for the next generation of single-aisle aircraft.”

“As founding partners in some of the aerospace sector’s most vital engine programs, we remain fully dedicated to supporting these platforms and collaborating on future propulsion technologies—especially for upcoming single-aisle aircraft,” said Shane Eddy, President of Pratt & Whitney. “As we map out IAE’s future propulsion strategy, ensuring the performance of today’s GTF program—and delivering on our commitments to customers—remains our top priority.”

“Our contribution to the consortium spans the entire engine lifecycle, from technology and development to production and MRO,” added MTU CEO Dr. Johannes Bussmann. “As strategic partners, we have consistently supported one another through ramp-ups, growth, and expansion for both the V2500 and GTF programs. MTU has been part of the GTF MRO network since 2015 and continues to expand facilities, capabilities, and agreements to meet rising demand and serve the growing fleet.”

Since its founding in 1983, IAE has developed some of the industry’s most pivotal commercial engine programs. The proven V2500—which surpassed 300 million flight hours earlier this year—powers around 2,800 aircraft and supports more than 150 operators worldwide across passenger, cargo, and military missions.

Looking ahead, the GTF engine family is projected to exceed 300 million flight hours by the mid-2030s. This extensive operational experience positions IAE to deliver the lowest-risk solution with the optimal balance of enhanced performance and mature reliability.

For the second-generation GTF, IAE is investing in a suite of advanced technologies, including next-generation materials, high-performance-computing-driven aerodynamics, a compact high-speed core, and hybrid-electric propulsion—ensuring the engine meets the performance demands of future aircraft.
