US states are entering a fierce competition to attract defense manufacturing jobs and contracts as the Pentagon accelerates efforts to replenish munitions depleted during the ongoing conflict with Iran.

The push is driven by a massive trillion-dollar defense budget request from President Donald Trump, which prioritizes restocking conventional weapons and developing next-generation hypersonic missile systems.

The financial toll of the US-Iran engagement has already been substantial, with war-related expenditures estimated at $40 billion.

Lessons from the wars in Ukraine and Iran have highlighted the finite nature of current munitions supplies, prompting the administration to treat industrial base expansion as a critical national security imperative.

This has triggered a bidding war among state governments eager to secure federal investment and high-skilled employment in the defense sector.
