Trump Announces Largest-Ever US Steel Plant in Key Red State with $15B Investment

President Donald Trump announced plans for a massive new steel plant in Iowa that the White House says would become the largest facility of its kind ever built in the United States. The project represents an investment of roughly $15 billion and is expected to create about 1,750 permanent jobs once the plant is fully operational.

Construction alone could support between 5,000 and 6,000 jobs during the facility’s first phase, according to administration estimates. Trump unveiled the project alongside executives from Mesabi Metallics, the company planning to develop the facility.

The plant would use iron ore supplied by Mesabi’s mining operation in neighboring Minnesota, creating what the administration describes as a domestic supply chain stretching from raw materials to finished steel. During its first phase, the Iowa operation is expected to produce approximately 7.5 million tons of steel each year.

Production could eventually rise to 10 million tons annually, a level the White House says would make the facility the largest steel plant ever constructed in the country. For comparison, that planned annual output would represent a sizable share of total U.S. steel production.

The administration says the project is also designed to strengthen domestic manufacturing capacity in industries tied to national security and critical infrastructure. The facility is expected to produce high-grade steel capable of meeting defense-sector requirements, reducing reliance on foreign sources for strategically important materials.

“President Trump is delivering on his promise to rebuild American industry, reshore manufacturing, and create new jobs,” White House spokeswoman Taylor Rogers said.

“Today’s announcement underscores the President’s historic efforts to revitalize the U.S. steel industry—supporting local communities, strengthening supply chains, and protecting our national security,” Rogers added.

The administration has pointed to tariffs and other trade policies as part of its broader effort to encourage companies to build manufacturing facilities inside the United States.

Trump previously increased tariffs on imported steel and aluminum to 50%, arguing that stronger protections were necessary to support domestic producers.

Those policies have also carried tradeoffs. Federal data cited in the report showed prices for iron and steel increased between April 2025 and April 2026, raising costs for some companies that rely heavily on those materials.

Unlike many newer American steel facilities, which operate as smaller electric-arc furnace plants, the proposed Iowa project would be a much larger integrated operation.

The White House described it as the first new “mega-steel” plant built in the United States since the 1960s. Combined with Mesabi’s Minnesota mining operation, the first phase of the broader project represents nearly $18 billion in planned investment.

The administration estimates that construction and the plant’s first decade of operation could generate roughly $95 billion in economic activity.

However, the development will take years to complete. Mesabi currently expects the Iowa facility to begin producing steel in 2030.

The company’s Minnesota operation has also faced a long development history that included financing problems, missed deadlines and a bankruptcy involving a predecessor company.

More recently, Mesabi has begun mining and commissioning work at the Minnesota site, with initial production of direct-reduction-grade pellets targeted for late 2026.

The White House estimates that the Minnesota operation will ultimately produce roughly 7.5 million tons annually while supporting about 350 permanent jobs.

If the Iowa facility reaches its projected capacity, the project would represent one of the largest expansions of American steelmaking capacity in decades and a major test of the administration’s push to bring more heavy industry back to the United States.
