The U.S. Air Force issued a Small Business Innovation Research solicitation for mobile 3D concrete printers to erect protective structures, with submissions closing in January 2027. The effort follows Iranian attacks that damaged hundreds of U.S. military buildings across eight Middle Eastern countries.
Why it matters
The Air Force says it has housed airmen in tents, trailers, and flat-walled structures not designed for the threat environment. The project aims to field shelters that can be produced quickly by lightly trained personnel where conventional construction is impractical.
The Air Force issued the solicitation as a direct-to-Phase II project, with submissions closing in January 2027. A September 2026 Department of Defense Inspector General report documented the building damage that prompted the effort.
The players
U.S. Air Force
The branch of the U.S. armed forces issuing the solicitation to develop mobile 3D concrete printers for protective structures.
Department of Defense Office of the Inspector General
The federal watchdog office within the Pentagon that released the September 2026 report documenting damage to military buildings.
The details
The project will evaluate cement-like materials for strength, adhesion, and local component availability, and develop construction geometries intended to improve blast and fragmentation survivability. The printers deposit layers of material to form structures, and the Air Force wants systems operable in austere conditions.
Timeline
September 2026: Inspector General report documents damage to hundreds of U.S. military buildings.
January 2027: Submission deadline for the Air Force SBIR solicitation.
Roadmap
The Air Force's 2023 use of 3D printing to rebuild hurricane-damaged Tyndall Air Force Base in Florida is the precedent for this solicitation, which extends the technology from disaster recovery into expeditionary, threat-hardened construction. A Maryland Air National Guard civil engineer squadron is separately developing its own mobile concrete printer, indicating parallel efforts within the military.
Small businesses with expertise in construction technology or cement-based materials may consider the Air Force SBIR solicitation, which closes in January 2027. Commercialization of such printers would likely require numerous approvals, including building codes, before civilian construction use.
The takeaway
The Air Force is pursuing 3D concrete printing as a way to replace tents and trailers with blast-resistant shelters that can be built quickly in the field. Its success would also carry dual-use value for critical infrastructure and humanitarian relief.
What happens next
The solicitation submission deadline is January 2027, when the Air Force will receive proposals for the mobile concrete printer project.
