For most of the twentieth century, General Electric was the closest thing American industry had to a household name that lived up to the word. It made the light bulb in the lamp, the motor in the refrigerator, the turbine in the power plant down the road, the MRI scanner at the hospital, and the credit card in a lot of wallets. If a thing plugged in, spun, or hummed, GE probably had a hand in it. Then, in a move that would have been unthinkable to the executives who built it, GE decided to stop being all of that.
Between 2021 and 2024, the company deliberately broke itself into three separate, publicly traded companies. The healthcare business became GE HealthCare. The energy business - wind, gas turbines, grid equipment - became GE Vernova. And the original corporate entity, the one that kept the 130-year-old monogram and the historic stock ticker, narrowed itself down to a single thing: aircraft engines. That company is GE Aerospace, and it is the subject of this profile.
01What GE actually does now
Strip away the history and GE Aerospace is a propulsion company. It designs, builds, and - crucially - maintains the engines that hang under the wings of commercial airliners and inside military jets and helicopters. Its commercial catalogue reads like a tour of every widebody you have ever boarded: the GE90, the sole engine on the Boeing 777; the GEnx, which wins roughly seven of every ten Boeing 787 Dreamliner orders; and the GE9X, the largest and most powerful commercial jet engine ever certified, built for a single aircraft, the Boeing 777X. Its fan spans nearly eleven feet, about the width of a 737's fuselage.
The volume, though, comes from a partnership. Through CFM International, a 50/50 joint venture with France's Safran that has run continuously since 1974, GE co-builds the narrowbody engines that move most of the flying world. The older CFM56 powers more than 14,650 aircraft. Its successor, the LEAP, is the fastest-selling engine in aviation history, with more than 3,500 already in service on the Boeing 737 MAX and Airbus A320neo. Roughly two CFM engines roll off the line every working hour, and GE builds half of every one.
02The razor and the blade, at 35,000 feet
Here is the part that makes GE Aerospace genuinely interesting as a business, not just as an engineering feat. A jet engine is one of the most complex machines ever mass-produced, and GE often sells a new one at a thin margin - sometimes at a loss. That sounds like a mistake. It is the entire strategy.
An engine bolted to an aircraft is a machine that will fly for 25 or 30 years, and across those decades it needs spare parts, inspections, and periodic overhauls - all of which GE and its partners are best positioned to supply. The new-engine sale is the razor. The decades of aftermarket service are the blade, and the blade is where the profit lives. In 2025, services revenue rose 28%. This is why an engine order is better understood as a multi-decade annuity than a one-time transaction.
That installed base is the moat. GE Aerospace supports roughly 44,000 commercial and 26,000 military engines in service around the world. Every one of them is a future stream of shop visits and spare parts. It is a business that compounds quietly: the more engines GE puts into the sky today, the more predictable its cash flow becomes for the next three decades.
03Who buys it, and how the money splits
GE Aerospace's customers are the aircraft makers - Boeing, Airbus, and others - along with the airlines and leasing companies that fly the jets, business-jet operators, and militaries led by the U.S. government. The company reports in two segments. Commercial Engines & Services is the giant, generating about $33 billion in 2025. Defense, Propulsion & Additive Technologies - fighter and rotorcraft engines, plus advanced work like the XA100 adaptive-cycle engine - added roughly $10 billion.
04Why break up a giant?
The obvious question is why a company this storied would voluntarily dismantle itself. The short answer: the conglomerate had grown slow, indebted, and hard to value. Investors could not tell whether they were buying an aviation firm, a hospital-equipment maker, or a power company, so they discounted all of it. Under chief executive Larry Culp, GE bet that three focused companies, each with its own board, its own capital, and its own story, would run faster than one sprawling one.
The healthcare arm spun off first, in early 2023, trading as GE HealthCare. In April 2024 the energy business separated as GE Vernova, and the aviation company kept the historic name and became GE Aerospace. The market's verdict was unambiguous: within a couple of years, the three separate companies were collectively worth far more than the single conglomerate had been. The turnaround was, in a sense, an act of subtraction.
05The engineering, and the odd-looking future
GE Aerospace runs on an internal management system it calls FLIGHT DECK - a lean operating model borrowed from the factory floor, built around safety, problem-solving, and continuous improvement. It is the connective tissue Culp used to reshape the culture of a company designed for very long product cycles. An engine program can take a decade to develop and then fly for thirty years; patience is a structural requirement, not a virtue.
The clearest window into where the company is heading is the RISE program, again run through the CFM venture with Safran. Its centerpiece is an open-fan engine - one that does away with the cowling wrapped around the fan of a conventional turbofan. It looks unusual on purpose. By exposing a larger, slower-turning fan, the design aims to cut fuel consumption and carbon emissions by around 20% compared with today's engines, while remaining compatible with 100% sustainable aviation fuel. Entry into service is targeted for the mid-2030s. The bet is quietly radical: that the biggest efficiency jump in a generation comes from taking something off the engine, not adding it.
06A company Edison helped start
The depth of GE's engineering bench is not an accident of the present; it is the residue of 133 years. The company was formed in 1892 when the financier J.P. Morgan merged Thomas Edison's Edison General Electric with the Thomson-Houston Electric Company, ending a bruising patent fight between two of the era's electrical pioneers. Charles A. Coffin, who had run Thomson-Houston, became GE's first president. Edison sat on the board for about a decade before drifting off to other projects. Four years after its founding, GE was named one of the twelve original companies in the Dow Jones Industrial Average, a spot it would hold for more than a century.
Aviation entered the story early, growing out of GE's turbine and turbosupercharger work in the years around the First World War, and it never left. That is the quiet advantage the modern company inherited: a research culture that thinks in decades, tens of thousands of engineers, and a habit of solving problems - metallurgy, cooling, aerodynamics - that only reveal themselves at temperatures hotter than molten lava and speeds no other industrial product endures. Today GE Aerospace employs on the order of 55,000 people, and in 2025 it announced plans to hire hundreds more engineers as demand for engines and their servicing climbed.
07Where it sits in the market
In large engines, GE Aerospace shares the world with two main rivals: Pratt & Whitney, part of RTX, and Britain's Rolls-Royce. Safran sits in the strange position of being both GE's closest partner, through CFM, and, on some fronts, a competitor. In the narrowbody segment that matters most for volume, the LEAP goes head to head with Pratt & Whitney's Geared Turbofan. What sets GE apart is less any single engine than the sheer size of its installed base and the aftermarket machine wrapped around it - a lead measured in decades of accumulated flying hours.
The through-line from Edison's light bulb to a cowling-free jet engine is a company that keeps deciding what it wants to be. For 132 years the answer was "almost everything." Since 2024, the answer has been narrower and, so far, more valuable: the part that flies.
