The U.S. Air Force has awarded a $40 million contract to rebuild aging Arctic radar infrastructure across northern Canada. The move extends the operational life of NORAD’s North Warning System as concerns grow over cruise missile and polar-route threats approaching North America.

The effort will replace deteriorating radomes protecting AN/FPS-124 low-altitude surveillance radars. Officials aim to preserve continuous early-warning coverage across remote Arctic corridors while future sensing systems remain years from deployment.

The Air Force announced the contract on May 19, 2026. IAP World Services, based in Melbourne, Florida, secured the deal under a long-term indefinite-delivery/indefinite-quantity structure running through May 2035. The Air Force Life Cycle Management Center’s Homeland Surveillance Branch at Hill Air Force Base manages the program.

Rebuilding Arctic radar coverage

The contract covers production, transportation, installation, removal, and disposal of 28-foot composite radomes. These structures protect unattended AN/FPS-124 radar sites spread across northern Canada.

The radomes shield sensitive radar equipment from harsh Arctic conditions. Crews must deal with icing, corrosion, ultraviolet exposure, thermal cycling, and extreme winds.

The AN/FPS-124 network plays a critical role inside NORAD’s Arctic surveillance architecture. The short-range radars track low-flying aircraft and cruise missiles that can avoid larger radar systems.

The North Warning System stretches across Alaska, Yukon, the Northwest Territories, Nunavut, and Labrador. It includes about 15 AN/FPS-117 long-range radars and nearly 40 AN/FPS-124 short-range sites. NORAD jointly operates the network through U.S. and Canadian cooperation.

Why the Arctic matters

Most AN/FPS-124 radomes entered service between 1990 and 1992. They replaced infrastructure from the Cold War-era Distant Early Warning Line.

More than three decades of Arctic exposure have severely degraded many structures. NORAD now considers sustainment more practical than immediate retirement.

For the United States, the Arctic remains strategically important. The polar region provides the shortest route between Russia and North America.

Russian bombers and long-range cruise missiles can approach through northern corridors. That makes persistent radar coverage essential for aerospace defense and early warning missions.

The larger AN/FPS-117 radars provide wide-area surveillance. However, they struggle to track low-altitude threats hidden by terrain and radar horizon limitations.

The AN/FPS-124 network fills those gaps. It focuses specifically on low-flying aircraft and cruise missiles operating beneath long-range radar coverage.

Logistics drive program costs

The Air Force first outlined the radome replacement effort in May 2025 through a presolicitation notice. Officials later issued a formal request for proposals in August 2025. Four bidders participated in the competition.

Initial planning estimated the effort at roughly $21.7 million. The final contract nearly doubled that figure because of the operational complexity tied to Arctic logistics.

Transporting equipment into isolated northern locations remains one of the program’s largest challenges. Aircraft availability, weather delays, and seasonal access windows continue to complicate installation schedules.

The Air Force combined fixed-price and cost-reimbursement structures to manage those uncertainties. Fiscal 2025 and 2026 funding obligations currently total about $4.6 million.

The service plans to phase replacements through future task orders instead of replacing the entire network at once. Unlike airborne surveillance missions, the unattended radar chain operates autonomously through remote command links.

The sites process radar data locally before transmitting it through satellite communications into NORAD command networks. Those systems connect directly to operations centers at Elmendorf Air Force Base and CFB North Bay.

The latest investment signals that NORAD still considers fixed Arctic radar infrastructure essential. That reliance will likely continue while future over-the-horizon and distributed sensing systems remain under development.
