The companies in Arlington are predominantly large firms in the manufacturing sector, particularly within aviation, aerospace, and defense. Key players include RTX, a global aerospace and defense firm; Boeing, an aerospace leader; Raytheon, which develops integrated air and missile defense systems; and Leonardo DRS, providing advanced sensing and force protection technologies. Other notable companies are Martin Sprocket & Gear, a manufacturer of power transmission components, and Oil States Industries, focused on energy and industrial equipment. This list features a strong presence of established companies, with many founded before the mid-20th century.
A significant pattern observed is the concentration of large-scale manufacturing operations, many with a long history. For instance, Boeing was founded in 1916 and Raytheon in 1922. While the core is defense and aerospace, there's also representation from industrial machinery manufacturing like Iscar Metals and plastics manufacturing by Mack Molding Company, indicating a diverse manufacturing base within the region.

How this list is built
Every company on this list has a Tamtam company profile. The industry is the one the company gives on LinkedIn; categories such as SaaS or fintech are classified by Tamtam's AI from the company's website and LinkedIn page; and the headquarters city must match the company's own address. Companies are ranked by the number of employees on LinkedIn, and the list is refreshed every night. Classifications can be wrong, so treat the list as a starting point rather than an official ranking. Last updated Nov 11, 2026.
