The industrial sector is the foundation of a robust economy, with companies providing machinery and engineering solutions critical to the scaling of heavy productions. In the US, industrial companies are key players in the economy, enabling the competitive expansion of other key sectors.
American industrial companies are operating across a number of activities that support multiple other activities including transport, energy, defense, and even agriculture. With the largest industrial players involved in the production of civil and military sea, air, rail, road and space transport, heavy machinery, farm and construction vehicles and equipment, and logistics, these companies are the skeleton upon which the US economy stands.
Though the number of actual industries and businesses in which the top industrial companies evolve is rather narrow nominally, the need for their specialty in advanced engineering and mechanics, together with related technologies makes industrial companies reach almost all the other economic sectors.
Besides, many of them are also critical to the development of infrastructure and defensive capabilities for the US government, and that of multiple other countries around the world. Many of the top industrial companies are critical aerospace and defense contractors for the US military and engaged in a very close relationship with the political system.
Close to the US government, the industrial sector is also a key barometer to the country’s economic activity. From the demand for industrial machinery to heavy transports like ships, rail, and planes, from heavy farming vehicles and construction machinery and equipment, the dynamism of industrial companies demonstrates the strength of the real American economy.
