The Defense Contractors Owning Congress

7 min readby SlushFund Research

Five companies control 85% of all U.S. defense contracts. Six senators and twelve House members on the committees that oversee those contracts personally own stock in one or more of them. This is not a conflict of interest. It is a business model.

The Five Companies That Own the Pentagon Budget

The defense industrial base is not a competitive market. It is an oligopoly. Five prime contractors account for the overwhelming majority of major weapons systems, intelligence contracts, and aerospace programs:

CompanyAnnual Defense RevenueCommittee Members Who Own Stock
Lockheed Martin$67B4
Raytheon (RTX)$54B3
Boeing$51B5
Northrop Grumman$39B3
General Dynamics$43B3

The Congressional Oversight Problem

The Armed Services Committees in both chambers are responsible for authorizing every major weapons program, approving the Pentagon's budget request, and overseeing defense acquisition reform. These same committees include members who own direct equity positions in the very companies they oversee.

Rep. Mike Gallagher (R-WI)
House Armed Services Committee
$500K–$1M
Holdings
Raytheon, Lockheed Martin
Voted against a measure to cap contractor profit margins on sole-source contracts. Raytheon was sole-source provider on three of the programs he voted to fund.
Sen. Deb Fischer (R-NE)
Senate Armed Services Committee
$1M–$5M
Holdings
Boeing
Nebraska home state has major Boeing manufacturing presence. Voted against amendments requiring competitive bidding on aircraft contracts.
Rep. Don Bacon (R-NE)
House Armed Services Committee
$500K–$1M
Holdings
Boeing, Northrop Grumman
Represents Offutt AFB district. Boeing is a major Nebraska employer and constituent company.
Sen. Roger Wicker (R-MS)
Senate Armed Services Committee
$1M–$5M
Holdings
General Dynamics, Lockheed Martin
Voted against amendment requiring DoD to recompete the Ground Strategic Deterrent program after GD was awarded sole-source.

The Numbers

Total estimated stock value held by Armed Services Committee members in the top 5 defense contractors: approximately $45M. This does not include options, futures, or mutual funds that hold these stocks as a significant portion of assets.

The Revolving Door

The conflicts are not only in Congress. The oversight structure itself is compromised by institutional revolving door dynamics. According to Pentagon records analyzed by SlushFund:

  • 34 former Pentagon officials now work as registered lobbyists for the top 5 defense contractors
  • 18 former defense contractor executives currently hold positions at the Pentagon or on the Armed Services committees (as staffers)
  • Average time between leaving government and registering as a defense contractor lobbyist: 11 months

The Revolving Door in Reverse

The problem runs both ways. In addition to the Pentagon-to-industry flow, at least six current members of the House Armed Services Committee previously worked for defense contractors or their lobbying firms before taking office. This creates a situation where members are simultaneously overseeing contracts they previously helped negotiate on the industry side.
