Commercial airliners rely heavily on jet engines, complex mechanical marvels that play a pivotal role in aviation. These engines are central to modern airplanes, requiring cutting-edge design for optimum performance and fuel efficiency. Although the exact list prices for jet engines are not typically disclosed by manufacturers, estimates suggest costs running into tens of millions of dollars, varying with size, complexity, and intended use.
Discounts are often available when airlines purchase engines in bulk as part of aircraft orders. Additional expenses can arise from support and services contracts. For instance, Singapore Airlines purchased 62 GE9X engines for its Boeing 777-9s, priced collectively at $2.8 billion, translating to a per-unit cost of $45 million prior to any discounts and inclusive of a 12-year service agreement.
CFM International, a collaboration between GE Aerospace and Safran Aircraft Engines, has supplied over 38,000 engines globally. Notable models include the CFM56 and the LEAP engine, each employed across prominent aircraft series. The CFM56 has a price point of about $12 million, while the LEAP engine is estimated to cost $15 million.
