Future Supersonic Passenger Aircraft – Concorde’s Return?

Future supersonic passenger aircraft
It takes about six hours for a conventional commercial airliner to fly from New York to London. These six hours can be seen as incredibly long for a flight. Some passengers desire to have their flying and traveling time reduced. Supersonic travel was a solution to the problem. Supersonic planes travel faster than the speed of sound at higher altitudes. However, this idea is not new. Supersonic aircraft were around decades ago. Development for these aircraft exists back in 1960! Today, they are companies that wish to bring back supersonic passenger aircraft to the world. Companies like Aerion Supersonic and Boom are working on bringing back passengers traveling faster than the speed of sound.

Boeing 2707 was the first American supersonic passenger jet project. The project won a competition between other US aerospace companies as to who can come up with the best supersonic passenger aircraft. The Boeing supersonic jet project was then helped funded by the US government. The Boeing 2707 was expected to fly faster than Mach 2.2, have operating costs close to subsonic jets, and can hold more than 150 passengers. The Boeing supersonic passenger jet was never built because the material needed for the fuselage (titanium) was expensive, sonic boom problems and public concerns with the environmental impacts.  The project was canceled in 1971 after going over budget and being delayed for some years. The Boeing 2707 never made it in the skies. However, the British and French joined together and were successful in producing a supersonic passenger jet. This was the beginning of the Concorde.


Concorde supersonic passenger jet Concorde first took off March 2nd, 1969. Passengers first traveled on the jet on January 21, 1976. The Concorde speed was peaking up to Mach 2.04, twice the speed of sound! At these speeds, the Concorde flight time was remarkable for a passenger jet. The aircraft could take only 3 hours to travel from New York to London! The technology that the aircraft had at its time was truly remarkable. With such great technological advantages, why was the Concorde retired? The disadvantages of the aircraft were plentiful and could not be ignored. The Concorde interior was not comfortable. The cabins were cramp and had little space. Airliners during its time, like the Boeing 747 for example, could have held and accommodated more passengers. Each passenger would be more comfortable in a Boeing 747 than in a Concorde. This might be “worth the wait” for many passengers, as the aircraft flew slower than the Concorde. The aircraft was only able to fly over the sea because it was banned from flying over land. This rule was implemented due to the incredibly loud sonic boom the aircraft created. A sonic boom is an astonishingly loud sound created by shock waves when an object is traveling faster than the speed of sound. The sound can be so loud that windows on the ground can break! Its range limitations only allowed the aircraft to cross the Atlantic Ocean, therefore limiting route options. Concorde ticket prices were quite high. A one-way ticket could have cost up to $12,000! This was due to the gross amounts of fuel the aircraft burnt and high maintenance cost. Only British Airways and Air France had the Concorde in their fleet. Slower airliners at that time would get you to the same destination cheaper. Giving all these disadvantages the Concorde had, the crash that occurred on July 25th, 2000, and the decline in air travel the next year, due to the September 11 events, forced the jet into retirement in 2003.

Obstacles With Supersonic Jets

Concorde made the world know what to expect with supersonic passenger air travel. Problems the Concorde faced and other concerns when traveling at fast speeds have to be noted and worked out in order to be successful. Obstacles new supersonic companies need to take into consideration are:
  • Regulations & certifications – Certain tests must be done in order for the aircraft to become airworthy.
  • Fuel price and usage – Supersonic jets use more fuel than subsonic jets. If fuel prices are high and the planes use a lot of fuel, customers will not be interested.
  • Loud engines – Those that live near airports will complain if these aircraft are too loud.
  • Sonic boom – If the sonic boom can still be heard from the ground while the jets are flying, overland operations may not occur.
  • Extensive research – Engineers have to ensure traveling at these high speeds do not cause any failures or problems.
  • Maintenance cost – If it cost too much money to maintain the aircraft, customers may not be interested in purchasing.
  • Initial cost – High purchasing cost can “turn off” customers.
Despite these challenges, a handful of companies are still planning on manufacturing and putting supersonic passenger jets back on the market.

Aerion Supersonic

Aerion Supersonic is a startup aerospace company that plans on creating supersonic jets. They aim is to make their aircraft:
  • Have engines that can run with 100% biofuel operations.
  • Travel at supersonic speeds without an afterburner.
  • Conduct carbon-neutral operations.
  • Have no sonic boom noise heard by people on the ground
Their first aircraft, Aerion AS2, is expecting to hold a maximum of 12 passengers and travel up to Mach 1.4. It is marketing towards private and luxury travel. The company is currently located in Reno, Nevada. However, they will be moving to Melbourne, Florida soon. They will be constructing their global headquarters there and call it “Aerion Park”. The Aerion AS2 was first announced in May 2014. It was developed from the Aerion SBJ, a previous concept that was first announced back in 2004. Aerion plans on starting to manufacture the aircraft 2023. The first flight is currently expected to occur in 2025. A $4 billion development cost is anticipated! Each aircraft is projected to be $120 million each. Aerion predicts that 300 AS2’s will be purchased over 10 years of service. Aerospace companies and the government are helping by investing in the project. The new headquarter in Melbourne, Florida hope to generate at least 675 jobs in Florida by 2026. Over the years, the company worked with large aerospace organizations to help with the project. Some of these companies are:
  • Boeing – A partner that provides engineering, flight testing, and marketing values.
  • General Electric Aviation – Building the engines for the aircraft. It is called GE Affinity.
  • Flexjet –  Launch customer for the AS2, placing a firm order of 12 jets valued at $2.4 billion!
  • Collins Aerospace – Will be designing flight controls of the actuation systems.
  • Jetex – Shall be able to accommodate customers at their FBOs.
  • Safran – Will be developing the braking, landing system, and engine nacelles.
A project of this magnitude will face major changes that require smart and innovative individuals to solve. Some problems that the company is facing are:
  • Covid-19 – Boeing had to bring back some engineers to reduce costs. This push back development.
  • Certification and Regulations – Special and unique processes had to be done to certify a new supersonic passenger jet.
  • Design Changes – Wing type, engine placements, and tail design were changing over the years.
  • Orders – Only one customer made orders for the jet. The aircraft is expensive compared to the best private jets on the market today.

Boom Supersonic

Boom Supersonic is also planning on releasing a passenger supersonic jet to the world. They are an aerospace company based in Denver, Colorado. They are aiming to make their aircraft:
  • 100% carbon neutral.
  • Use low-carbon jet fuel technology.
  • Designed for recycling principles.
Boom’s supersonic airliner will be called Boom overture. It is expecting to travel Mach 2.2 and carry 55 passengers. Overture will be marketed towards airliners that want to promote a more luxurious and fast travel experience. It hopes to be the most sustainable and fastest supersonic airliner. Boom Supersonic Overture is aiming to be unveiled the year of 2025 and is fully certified by 2029. The first aircraft that is being constructed is the Boom XB-1. The XB-1 has its first flight on October 7th, 2020. It will not be able to hold any passengers. Its mission is to represent as a demonstrator for the Overture. It will basically be their research and test plane before creating their larger passenger variant. Boom appears to not focus on eliminating the sonic boom completely for their aircraft. They are pushing towards airliners who fly transoceanic routes. This likely means only airliners who conduct long haul operations will benefit from the aircraft.

Will Supersonic Travel Dominate Aviation?

Aerospace companies that will bring supersonic jets back to the skies. The question is “will it be successful?” Supersonic aircraft have their advantages and disadvantages. They are fast, can fly at higher altitudes, and help to influence new technologies. However, they tend to use and burn more fuel, create loud sonic booms on the ground, and are expensive to maintain. The Concorde was not privileged with better technology and lower fuel prices. Adding that with expensive maintenance caused an expected retirement. New supersonic jets need to learn from the Concorde’s mistakes in order to be successful. If they manage to overcome these impediments, then your airline flights will soon be traveling twice the speed of sound! What are your thoughts on supersonic travel? Feel free to comment below!

  1. I loved reading this article. It reminded me of my childhood where I asked my grandad about DJ Concorde. With him being a plane enthusiast, he told me many cool things about the concord. Your post reminded me of these times. I would love to travel on such a vehicle. However, at £12,000 a ticket I think it’ll have to wait.

    1. Yes, at these prices, average people would not be able to afford Supersonic travel. We’ll just have to wait and see what these new supersonic companies have in store for us!

  2. I love your articles-your style is very easy to read and there is always something to learn! You reminded me today of the cartoon stripes of only a few squares in weekly newspapers decades ago, with Daisy Duck, baking a rising sponge cake which in the last minute got ruined by a supersonic aircraft breaking the sound barrier just over her house 😉 It was so funny!
    It sure would be nice to travel that fast from A to B. I hope it will be possible some day in the regular passenger air traffic. But, as you said yourself, there still are issues to be solved.
    Air transport is a business as any other. It needs consumers, i.e. passengers. And if the price of such a flight will be significantly higher than that of by the traditional aircrafts, not many people will be able to afford buying a ticket.
    However, even so, if it starts, one day it will become affordable to average people, as well, as it was the case with flying itself.
    Looking forward to witness it.

    1. Typically, passengers purchase the cheapest tickets to get to their destination. Supersonic travel are for those who values their time more. Thank you for your compliments.

  3. It will be interesting to see if airline companies will purchase these aircraft in the future. Will they pay millions of dollars for a faster plane?

    1. If flight time is very valuable to passengers and the airline, then they may purchase the jets. Their maintenance cost shouldn’t be very expensive because that can turn off airline companies.
