List of megaprojects
Megaprojects may be defined as:
- Projects that cost more than US$1 billion and attract a lot of public attention because of substantial impacts on communities, environment, and budgets
- Projects can also be "initiatives that are physical, very expensive, and public"
Megaprojects require care in the project development process to reduce any possible optimism bias and strategic misrepresentation. Examples of megaprojects include bridges, tunnels, highways, railways, airports, seaports, power plants, dams, wastewater projects, Special Economic Zones (SEZ), oil and natural gas extraction projects, public buildings, information technology systems, aerospace projects, and weapons systems.
This list identifies a wide variety of examples of major historic and contemporary projects that meet one or both megaproject criteria identified above.
Aerospace projects

- Boeing B-29 Superfortress, the first nuclear bomber, which cost 50% more than the development of the bombs in the Manhattan Project.
- Boeing B-52 Stratofortress, the longest-running bomber program in the world with decades of service, one of the largest military aircraft ever built.
- Boeing 2707 and Lockheed L-2000 supersonic aircraft projects, initiated in 1963 via a US government-funded competition to build the United States' first Supersonic Transport (SST), prototypes never built, ultimately canceled due to political, environmental and economic reasons in 1971.
- Boeing 747, a wide-body commercial airliner first produced in 1970, often referred to by the nickname Jumbo Jet, is among the world's most recognizable aircraft.
