Finding defense tech companies

Use this directory to shortlist companies by mission area, capability and market. For a scan of the full published set, see the alphabetical company list. Compare company capabilities and government awards.

What counts as defense technology?

This directory covers companies developing products for defense and national security, including dual-use technology with civilian applications. Sector tags help distinguish autonomy, software, sensing, space and other capabilities.

How should I compare companies?

Start with the capability and market tags, then review each company’s public website. Federal award activity is useful context on reported public awards, but it is not a measure of product quality, company size or private funding.

Does the directory include only startups?

No. It includes both emerging companies and established suppliers.
