“Aerospace companies” are usually aerospace manufacturers, and they research, design, build, test, sell and maintain aircraft/aircraft parts, missiles, rockets and spacecraft/spacecraft parts. This can include but not limited to: space vehicles, aircraft engines and propulsion units. The aerospace industry is made up of military, industrial and commercial applications.

It must be noted that aerospace is different to airspace, which is classed as the air that directly above the Earth’s surface. The end of air and start of space is generally known to be about 100km from the ground, and this is determined by the air pressure being too low that high up.


The Aerospace Industry

As you can imagine, there are many aerospace manufacturers in the modern world, ranging from those who have been around for a century or more, to those who have been founded relatively recently. In 2017, the size of the global aerospace industry was worth about $838 billion. This will only continue to rise due to the increasing number of travellers around the globe, as flying becomes more accessible to more people, while airplane inspection standards also becoming more rigorous and leading to more airplane retirements. It is estimated that the global aerospace market will hit $16 trillion by 2038.

The United States has the largest aerospace industry in the world, with 49% of the entire global market located there. Then there is a huge gap in the market to second place France with 8.2% and China following in third with 7.3%. China’s aerospace industry is growing very fast in recent years, and they are estimating that over the next 20 years they will acquire $1.3 trillion worth of aircraft. This will in turn create more business (about $1.6 trillion) in aftermarket service for these aircraft.

Airbus’s most adventurous move throughout its history was when they created the huge A380, which was a double decker airplane that was so massive they had to totally redesign airport infrastructure to ensure that it would fit in them! The company ventured into the large aircraft division and found some success, and some notoriety with their A300-600 Super Transporter planes, which quickly became a crowd favorite due to its ridiculous design. Shaped like a Beluga whale, it was given the nickname Beluga almost immediately, and there was even a larger version of them made, called the BelugaXL (pictured)!

The company is divided into three main divisions:

Going forward, NASA has a renewed focus on climate change and reducing its carbon footprint on the world. They are focusing on increasing the efficiency and safety of current jet engines while also reducing CO2 emissions. Read about How to get a mechanical engineering job at NASA.

12. SpaceX

SpaceX or Space Exploration Technologies Corp., is an American space transportation and aerospace manufacturer that has its headquarters in Hawthorne, California. Elon Musk founded the company in 2002 to decrease the cost of space travel, with the ultimate goal of colonizing Mars! They have created many new rocket engines and launch vehicles, including the Starlink satellite constellation, the Dragon cargo spacecraft and they have transported humans to the International Space Station on the Dragon 2 spacecraft.

SpaceX has been a groundbreaking company in its relatively short history, one of its main achievements has been the development of the very first privately funded propelled-by-liquid rocket to travel to orbit with the Falcon 1 in 2008. Some of their other very impressive missions have involved being the first private company to launch, reach orbit and recover a spacecraft with the Dragon in 2010, and the first vertical take-off and propulsive landing for an orbital rocket in 2015 with the Falcon 9.

Not stopping there, SpaceX plans to unveil Starship, which will attempt to be the largest rocket ever and will be fully reusable, with its debut scheduled for the early 2020s. Musk has been vocal about his goals of reducing the cost of space travel by a factor of 10, with a goal of $500 per pound or less. His conquest to bring spaceships to Mars is also going full steam ahead, as two unmanned spacecraft are planned to travel to Mars 2022. These will be to seek out sources of water and build a propellant plant, and further spaceships will follow in 2024 with people! After that, Musk’s lofty goal of colonising Mars will begin, however, these plans are already experiencing significant delays.

13. General Dynamics

General Dynamics Corporation (GD) is an American defense and aerospace company. It is the fifth-biggest defense contractor in the US as of 2019, and is the sixth-biggest in the world by sales. It was formed in 1954 and is headquartered in Reston, Fairfax County, Virginia. It came into existence through multiple divestitures and mergers in the post-Cold War era. They make and provide missiles, submarines, rockets, tanks, fighters, electronics and warships to all military services.

It is segmented into the following areas: Aerospace, Combat Systems, Information Technology (IT), Marine Systems and Mission Systems. One of its most successful ventures was the Fighting Falcon F-16, which first flew in January 1974 and proved to beat its competition in performance testing. Once production began in 1975 orders surged and totaled more than 4,000, making it the most successful project in the company’s history, and once of the most successful western military ventures since World War 2.

14. Blue Origin

Blue Origin is an American sub-orbital spaceflight services company and aerospace manufacturer. It was founded by Jeff Bezos in 2000, and is headquartered in Kent, Washington. At its head, the CEO Bob Smith is leading the company’s charge to make space travel cheaper and more reliable through making spacecraft reusable.

They employ an incremental approach to adapt their suborbital flight to orbital flight, with a focus on rocket-powered vertical takeoff and vertical landing. They have not yet flown with passengers as the company has pushed back the date for commercial flights since 2018.

They entered the orbital spaceflight technology business in 2014, and supplied rocket engines to other aerospace companies before announcing plans to make and fly their own orbital vehicle. Testing for this “New Glenn” project is still in its testing phase as of 2021.

Blue Origin have big plans for the future with plans for a moon lander called “Blue Moon” scheduled for 2024.

15. Virgin Galactic

Virgin Galactic is an American aerospace and spaceflight corporation. Its ultimate purpose is to develop commercial spacecraft and give tourists the ability to go on suborbital space flights and launches for their space science missions. Virgin Galactic was founded by Richard Branson, and he purchased five SpaceShipTwo spacecrafts along with two WhiteKnightTwos to get the company off the ground (excuse the pun). Branson then predicted that Virgin Galactic would have its maiden voyage in 2008, but this was delayed after a disaster in 2007 that ended up killing three people during testing.

The maiden journey was set back further by an in-flight crash of the VSS Enterprise in 2014. Virgin Galactic finally achieved their goal by completing their first suborbital flight in December 2018, reaching an altitude of 82.7 kilometers. They then took another big step in the right direction by completing a flight in February 2019 that included three people, including one passenger.

Virgin Galactic has had its set-backs, but they continue to develop and progress towards their ultimate goal of having commercial space flights. With their new ships – the VSS3 and VSS 4, they will hope to achieve just that.
