Army Awards Mortenson $610M For USDA Screwworm Facility — 70x Media Estimate
Friday, March 6, 2026
M. A. Mortenson won a $610 million Army contract to build USDA's sterile insect production facility at Moore Airbase in Edinburg, Texas — a figure seventy times larger than the $8.5 million Bloomberg reported in June when the facility was first announced.4 The discrepancy isn't a rounding error. It suggests the contract bundles far more than a fly-rearing building: likely multi-year equipment procurement, automated production lines, MEP infrastructure, and possibly base-wide utilities or sustainment work that didn't make it into early USDA press guidance.
The mission is straightforward. New World screwworm — a flesh-eating parasite that can kill a cow in ten days — has been pushing north through Mexico after decades of eradication in the U.S.2 USDA's response relies on the sterile insect technique: flood the region with sterile male flies to suppress wild populations. Mexico is building a $51 million production plant;1 the U.S. is building its domestic capacity at Moore Airbase. The scale-up matters because screwworm outbreaks in 2025 twice forced the U.S. to halt cattle imports from Mexico,3 and ranchers near the border are prepping for the first stateside detections in forty years.
Mortenson brings two advantages. First, it built biosecure vaccine manufacturing facilities during the pandemic, including complex cleanroom and containment work.5 Sterile-insect rearing isn't BSL-4, but it requires precise environmental controls, contamination barriers, and often gamma irradiation systems for sterilization — closer to pharma than to a typical warehouse. Second, Mortenson already executed a $67 million training center contract at Moore Airbase in 2023,6 so it has base access credentials, local relationships, and recent performance history with the same contracting office. In a two-offer competition for specialized biocontainment construction on a military installation, incumbency and biosafety experience are decisive.
The structure — Army as contracting agent, USDA as end user, military base as location — shows how agricultural biosecurity missions get routed through defense procurement when speed and interagency coordination matter. It also creates a clear opening for companies that supply automation, insect-rearing systems, and sterile-fly logistics: Mortenson builds the box, but someone else fills it with the production equipment that will run for years. If you're in ag-biotech or entomology automation, the prime is now known and the facility is funded.
