## Overview

SHIELD is the Missile Defense Agency's primary acquisition vehicle for the Golden Dome missile defense initiative. It functions as an Indefinite Delivery / Indefinite Quantity (IDIQ) contract structure that pre-qualifies commercial and defense vendors to compete for task orders without repeating full and open competitions.

## Structure

SHIELD operates as a "hunting license" model: Prime IDIQ position enables vendors to bid directly on task orders but does not guarantee revenue. Actual procurement requires winning specific task order competitions.
