Five GovCon Experts in the Defense Market

The Department of Defense relies on businesses of all sizes to support its mission. A Government Accountability Office report posted on July 7 revealed over 200,000 companies provide supplies, parts and manufacturing for the Pentagon’s weapons systems alone while a separate review from Mordor Intelligence found that the U.S. defense market is expected to grow from $541.6 billion to $629.93 billion by 2023.

Contractors in this space either specialize in supporting defense missions or have units dedicated to supporting the military. Executives in this sector have years of experience in overseeing defense-related services or were service veterans themselves, if not both.

The Potomac Officers Club – a division of Executive Mosaic – presents five government contracting experts in the defense market.
