Defense Industrial Base Sector: Critical Infrastructure and Key Resources

Sector Overview

The Defense Industrial Base (DIB) Sector includes Department of Defense (DoD), government, and the private sector worldwide industrial complex with the capabilities of performing research and development, design, production, delivery, and maintenance of military weapons systems, subsystems, components, or parts to meet military requirements.

The DIB Sector includes tens of thousands of companies and their subcontractors who perform under contract to DoD, and companies providing incidental materials and services to DoD, as well as government-owned/contractor-operated and government-owned/government-operated facilities. DIB companies include domestic and foreign entities, with production assets located in many countries.

The DIB Sector is dependent upon a number of other sectors, such as Energy,  Communications and Transportation Systems.

The DIB Sector provides products and services that are essential to mobilize, deploy, and sustain military operations. The DIB Sector does not include the commercial infrastructure of providers of services such as power, communications, transportation, or utilities that DoD uses to meet military operational requirements. These requirements, including cyber, are addressed in DoD’s broader Defense Critical Infrastructure Program (DCIP), where they are integrated in all DIB Sector activities.
