TECHNICAL DEFINITION

The Defense Industrial Base (DIB) is a nation's public and private industrial ecosystem, encompassing prime contractors, subcontractors, and suppliers, that performs research, development, design, production, delivery, and maintenance of military weapons systems, subsystems, and components to meet national security requirements.

BACKGROUND

A defense industrial base (DIB) is the network of organizations, facilities, and resources that provides a government with materials, products, and services for defense purposes, especially the supply of its military forces. It may include both public and private actors, including some entities that may not exclusively engage in defense-related production, and is often defined in geographical or national terms. It may also be divided according to the kinds of weapons and equipment produced. As a concept, the DIB is closely related to the notion of the military–industrial complex, and is often discussed as a foundational element of national power.
