Defence Secretary Pete Hegseth on Wednesday told a congressional hearing that the Trump Administration's proposed $1.5 trillion defence budget would "supercharge" domestic production capacity and restore the United States' ability to build weapons systems at scale. The sweeping proposal, reviewed by lawmakers in Washington, is aimed squarely at overhauling the country's defence industrial base and cutting reliance on foreign suppliers — including potential adversaries.

What the Budget Proposes

The plan includes major investments to expand domestic manufacturing, strengthen supply chains, and accelerate the production of munitions, ships, and advanced weapons systems. Officials said the strategy involves sending long-term demand signals to private companies, enabling them to scale production and invest in new plants and assembly lines.

Hegseth described the shift as moving from a "bureaucratic model to a business model," designed to encourage private sector investment. He told lawmakers that recent efforts have already triggered significant industry response, including new facilities and manufacturing expansion backed by private capital.

Lawmakers Acknowledge Years of Underinvestment

Members of both parties at the hearing acknowledged that prolonged underinvestment has weakened the US defence industrial base, leaving it dependent on foreign suppliers in critical areas. Committee Chairman Mike D. Rogers was direct in his assessment: "We're no longer capable of manufacturing for our warfighters at scale or speed," citing specific gaps in shipbuilding and munitions production.

Rogers also highlighted the stark contrast with China, noting that Beijing dominates global shipbuilding while US capacity has sharply declined. This comes amid broader geopolitical tensions, with the Pentagon increasingly framing industrial readiness as a core national security issue.

Military Leadership Backs the Push

Joint Chiefs Chairman Dan Caine told lawmakers that sustained investment is essential to maintain military readiness and adapt to evolving threats. He said modern warfare increasingly depends on industrial capacity, technology, and the ability to produce at scale — underscoring that the gap between defence ambition and manufacturing reality cannot be closed without long-term funding commitments.

The China Factor

The budget proposal arrives at a moment of heightened US-China competition. China's dominance in shipbuilding — where it accounts for the majority of global commercial vessel output — has long been a concern for US defence planners. The budget seeks to reverse America's declining procurement and research spending by directing funds toward domestic and allied supply chains, with the explicit goal of reducing strategic dependencies.

What Comes Next

The proposal will now face scrutiny from the full Congress, where defence spending priorities often become a battleground between fiscal hawks and national security advocates. Industry bodies are expected to respond to the long-term demand signals embedded in the plan, with new manufacturing investments likely to be announced in the months ahead. Whether the $1.5 trillion figure survives the legislative process intact remains to be seen.
