Top 11 Largest Aerospace Companies in the US

10. Spirit AeroSystems (NYSE: SPR)

Spirit AeroSystems is one of the newest companies in our list, and is actually a spin-off of Boeing, another company which will make our list later on. It actually came into being when Boeing Commercial Airplanes sold to investment firm Onex, its Wichita division. It has steadily grown since and made $7.8 billion in 2019, while also employing 18,200 people, which seems immense but that is the lowest number of employees we had in our list and is less than a tenth of some of the other companies you will see later on. It has purchased the aerostructures business from BAE systems, which is also one of the largest aerospace companies in the world, but is of British origins. Spirit had to pay around 80 million pounds to purchase the business. Spirit only has a couple of main customers, and in 2010, 96% of sales were to Boeing and Airbus.
