Ellsworth Air Force Base B-21 Raider Alert Facility

Project Overview

Conti Federal is constructing a secure, mission-critical Alert Facility at Ellsworth Air Force Base (AFB) in South Dakota to support continuous readiness for the B-21 Raider mission. The 22,000-square-foot facility provides secure lodging and readiness space for B-21 aircrews assigned to alert status, along with an Aerospace Ground Equipment (AGE) facility supporting alert operations and mission readiness.

Conti Federal is delivering the Alert Facility as part of its B-21 portfolio of projects at Ellsworth AFB. The projects are structured under a program-level enterprise delivery model to optimize resources, reduce risk, and improve program-wide coordination. Conti Federal’s enterprise team and ongoing operations at Ellsworth AFB have enabled the company to build a trusted network of local trade partners and subcontractors who understand the unique requirements of the installation and its broader mission.
