Les 15 avions les plus chers jamais construits

The 15 Most Expensive Planes Ever Built

March 8, 2026

Aviation is often associated with technological innovation, spectacular performance, and human achievements. But behind these extraordinary machines also lie colossal investments. Designing a modern aircraft requires years of research, thousands of engineers, and extremely expensive technologies.

In some cases, the price of an aeronautical program can reach tens, or even hundreds, of billions of dollars. New-generation military aircraft, in particular, are among the most expensive industrial projects ever launched.

But what are truly the most expensive aircraft in history? Between giant airliners, stealth bombers, and gigantic military programs, here is a ranking of the 15 most expensive aircraft ever built.

How is the cost of an aircraft calculated?

Before comparing the most expensive aircraft in the world, it is important to understand that several methods exist to evaluate their cost.

The unit price of the aircraft

The unit price corresponds to the cost of a single aircraft produced. In civil aviation, this is generally the price displayed by manufacturers for airlines, even if significant discounts are often applied.

In military aviation, the unit price generally includes equipment, avionics, and certain weapon systems.

The total cost of the program

The total cost of a program includes:

research and development
prototypes
flight tests
certification
production
sometimes maintenance over several decades

Some military programs reach astronomical sums when all these elements are included.

Embedded technologies

The more technologically advanced an aircraft is, the more expensive its development. The following technologies significantly increase budgets:

radar stealth
composite materials
advanced avionics
sophisticated weapon systems
new-generation engines

Ranking of the 15 most expensive aircraft ever built

Here is an overview of the aircraft that have required the most significant investments in the history of aviation.

15. Boeing 747

The Boeing 747 is undoubtedly one of the most iconic aircraft in history. When it was launched in the late 1960s, it represented a gigantic gamble for Boeing.

Its development cost approximately 1 billion dollars at the time, a colossal sum for the aeronautical industry.

The "Jumbo Jet" revolutionized air travel by allowing more than 400 passengers to be transported over long distances. For decades, it dominated international routes.

14. Airbus A380

The Airbus A380 is the largest airliner ever built. Its development represented a massive investment for Airbus.

The program cost approximately 25 billion dollars.

Despite its impressive capabilities and exceptional comfort, the A380 arrived at a time when airlines preferred smaller, more flexible aircraft.

Production was finally halted in 2021.

13. Boeing 787 Dreamliner

The Boeing 787 Dreamliner marks a major technological breakthrough in commercial aviation.

It is the first airliner built mainly from composite materials, which reduces weight and fuel consumption.

Its development is estimated to have cost more than 30 billion dollars.

Despite a difficult start, the Dreamliner is now one of the most popular long-haul aircraft in the world.

12. Airbus A350

Designed to compete with the Boeing 787 and Boeing 777, the Airbus A350 is an ultra-modern long-haul aircraft.

Its development cost approximately 15 billion dollars.

Thanks to its efficient engines and composite structure, it has become one of the most efficient aircraft in its category.

11. Lockheed Martin F-22 Raptor

The F-22 Raptor is one of the most advanced fighter jets ever built.

This fifth-generation aircraft combines:

stealth
supercruise
advanced avionics
exceptional combat capabilities

The program cost over 67 billion dollars, with a unit price exceeding 150 million dollars per aircraft.

10. Boeing B-2 Spirit

The B-2 Spirit stealth bomber is one of the most expensive military aircraft of all time.

Only 21 aircraft were built, which drives its unit cost up to approximately 2 billion dollars per aircraft when development costs are included.

Its ability to penetrate enemy defenses while remaining virtually invisible to radar makes it a major strategic weapon.

9. Lockheed Martin F-35 Lightning II

The F-35 is the most expensive military program in history.

This fifth-generation fighter is intended to replace numerous aircraft in the US armed forces and their allies.

The total cost of the program could exceed 1,700 billion dollars over its entire lifespan, including maintenance and operation.

8. Airbus A400M

The Airbus A400M is a military transport aircraft developed by several European countries.

The program experienced numerous delays and cost overruns, bringing its cost to over 20 billion euros.

Despite these difficulties, the A400M is now a strategic aircraft for military transport and humanitarian missions.

7. Boeing VC-25 (Air Force One)

The aircraft used to transport the President of the United States are heavily modified versions of the Boeing 747.

These aircraft incorporate secure communication systems, defense equipment, and capabilities allowing the President to lead the country in flight.

The cost of the new VC-25Bs could exceed 4 billion dollars.

6. Northrop Grumman B-21 Raider

The B-21 Raider is the US Air Force's future stealth bomber.

Although exact figures remain confidential, the program could cost over 80 billion dollars.

This aircraft is designed to gradually replace the B-2 and B-1.

5. Lockheed SR-71 Blackbird

The SR-71 Blackbird is a legendary reconnaissance aircraft capable of flying at over Mach 3.

Its design required materials capable of withstanding extremely high temperatures.

The program cost several billion dollars, a huge sum for the time.

4. Concorde

The Concorde remains one of the most ambitious projects in civil aviation.

This supersonic aircraft developed by France and the United Kingdom allowed crossing the Atlantic in less than four hours.

Its development cost approximately 3 billion dollars in the 1970s, much more in current value.

3. Boeing 777X

The Boeing 777X is the new generation of the famous 777.

With its folding wings and ultra-powerful engines, it represents one of Boeing's most ambitious projects.

Its development exceeds 20 billion dollars.

2. Tupolev Tu-160

The Tu-160, nicknamed "Blackjack" by NATO, is the heaviest supersonic bomber ever built.

Designed during the Cold War, it remains today one of the most impressive strategic aircraft.

1. Lockheed Martin F-35 (complete program)

Taking into account the entire life cycle of the program, the F-35 is considered the most expensive aeronautical program in history.

Its overall cost could reach over 1,700 billion dollars.

Why are some planes so expensive?

Several factors explain these gigantic amounts.

Ever more advanced technology

Modern aircraft integrate extremely complex systems:

advanced sensors
embedded artificial intelligence
AESA radar
stealth technologies

Each innovation requires years of development.

Programs are getting longer

The development of a military aircraft can take 15 to 20 years.

Each technical modification incurs additional costs.

Limited production runs

In some cases, only a few dozen aircraft are produced. This mechanically increases the unit cost.

Will future aircraft be even more expensive?

Everything indicates that future aeronautical programs will be even more costly.

Current projects include:

sixth-generation fighters
hypersonic aircraft
carbon-neutral aircraft
collaborative combat systems

These technologies could explode budgets in the coming decades.
