GE Aerospace Reports $210B Backlog on Spare Parts Surge

GE Aerospace reported a total company backlog exceeding $210 billion, driven by a 40 percent year-over-year surge in spare parts orders between early March and mid-May 2026.

In a second-quarter investor update published on June 8, 2026, the manufacturer detailed strong commercial aftermarket demand and outlined recent milestones across its military and advanced technology portfolios. The update followed recent executive appearances, including a May 27, 2026, presentation at the Bernstein Strategic Decisions Conference and a June 7, 2026, interview with Chairman and CEO Larry Culp at the International Air Transport Association (IATA) conference in Rio de Janeiro, Brazil.

Commercial aftermarket demand drives backlog

Commercial services now account for over $170 billion of the company’s total backlog. GE Aerospace reported a 30 percent increase in Commercial Engines and Services (CES) internal shop visit (ISV) revenue over the past 12 months. Spare parts revenue grew by more than 25 percent during the same period.

The manufacturer highlighted the longevity of its CFM56 engine program, noting the average fleet age remains under 15 years. The company projects that 80 percent of CFM56 shop visits over the next few years will come from engines under 20 years old. For newer generation powerplants, GE Aerospace expects the LEAP engine installed base to more than double between 2025 and 2030. In the widebody sector, the GEnx engine program maintains a life-of-program win rate exceeding 75 percent.

“These are encouraging indicators that underlying services demand remains robust. We are confident in our outlook and remain on track to deliver the high end of our full-year guidance.”

The company is scheduled to host its second-quarter earnings call on July 16, 2026, where it will provide further financial details.

Defense portfolio and advanced propulsion milestones

GE Aerospace currently powers two-thirds of United States military combat and rotorcraft fleets. The company hosted a Defense & Propulsion Technologies showcase at its Lynn, Massachusetts facility, where it reported a 30 percent engine output increase in 2025 achieved without additional headcount. The manufacturer projects that advanced defense programs will account for 25 percent of its defense revenue by 2035.

The investor update detailed several advancements in military propulsion programs. GE Aerospace completed the Assembly Readiness Review for the XA102 adaptive cycle engine, advancing the U.S. advanced combat propulsion program to prototype development. In the Collaborative Combat Aircraft (CCA) sector, the U.S. Air Force awarded the company a contract to complete a Preliminary Design Review (PDR) for a medium thrust CCA utilizing the GE426 engine. Concurrently, the GEK1500 engine, developed in partnership with Kratos Defense & Security Solutions for a lower thrust CCA, was selected to move to the PDR phase.

Next-generation technology and AI integration

The company reported progress on several experimental and next-generation propulsion initiatives. GE Aerospace demonstrated a generative artificial intelligence application capable of producing a preliminary hypersonic ramjet engine design in seconds, a development intended to compress early design work timelines.

In the electric and hybrid propulsion sector, the manufacturer partnered with BETA Technologies to develop a turbogenerator for the MV250 autonomous military logistics vertical takeoff and landing (VTOL) aircraft. GE Aerospace also completed the first ground test of a megawatt-class hybrid electric engine as part of the National Aeronautics and Space Administration (NASA) Electrified Powertrain Flight Demonstration (EPFD) project.

AirPro News analysis

We note that the 40 percent spike in spare parts orders reflects broader commercial aviation industry constraints. With new aircraft deliveries delayed across the manufacturing sector, operators are investing heavily to keep existing, older fleets operational. The CFM56 data provided by GE Aerospace illustrates this dynamic clearly, as airlines commit to major shop visits for engines that might otherwise have faced retirement in a more fluid delivery environment.

On the defense side, the rapid progression of the GE426 and GEK1500 engines through the Preliminary Design Review phase underscores the U.S. Air Force’s prioritization of the Collaborative Combat Aircraft program. The integration of generative AI into hypersonic ramjet design suggests manufacturers are aggressively seeking ways to shorten the traditional, decades-long military engine development cycle to meet emerging defense requirements.
