Conti Federal Awarded $49.8M Contract for B-21 Raider Environmental Protection Shelters

Marks tenth award supporting B-21 bed-down at Ellsworth Air Force Base

As the U.S. Air Force continues building the infrastructure needed to field the B-21 Raider, Conti Federal Services, LLC has been selected by the U.S. Army Corps of Engineers (USACE) Omaha District, to construct the $49.8 million 80 Row Environmental Protection Shelters (EPS) at Ellsworth Air Force Base (AFB). The award marks Conti Federal's tenth contract supporting the B-21 bed-down program, further expanding its role in one of the Air Force's most significant modernization initiatives.

Designed to shield aircraft from weather and other environmental conditions, the EPS will help preserve the B-21 fleet and support long-term operational readiness. Conti Federal’s scope of work includes the construction of six new pre-engineered metal environmental protection shelters totaling 20,000 square feet, three maintenance kiosks, all associated airfield paving and Ground Support Equipment (GSE) paving, and the partial demolition and repair of existing facilities.

The B-21 Raider’s stealth materials were engineered to be more durable than previous-generation stealth aircraft, reducing reliance on climate-controlled hangars for routine parking and protection. The Environmental Protection Shelters are intended to protect B-21 aircraft from environmental exposure while parked on the flightline, providing a cost-effective way to reduce dependence on enclosed hangar space, minimize weather-related maintenance and downtime, and improve mission readiness.
