Why Does the Defense Budget Matter to Economic Growth?
The defense budget matters to economic growth because it is the largest single source of demand for advanced manufacturing in the United States. The fiscal 2027 budget request, submitted to Congress in April 2026, proposed $892 billion in base defense spending. That figure includes $181 billion for procurement and $158 billion for research and development. These are not abstract transfers to the Pentagon. They are purchase orders for shipyards in Mississippi, semiconductor fabs in Arizona, and aerospace suppliers across the Midwest.
Defense procurement has a multiplier effect that many domestic programs cannot match. A 2023 study by the RAND Corporation found that defense spending on shipbuilding and aircraft generates roughly 1.4 times its direct cost in broader economic activity. The reason is straightforward. These contracts require skilled labor, domestic supply chains, and long-term capital investment. They do not disappear after one election cycle. A Virginia-class submarine takes roughly seven years to build. The workers trained for that program stay in the workforce for decades.
The alternative is industrial atrophy. The United States currently builds about 1.2 submarines per year. China builds more than four. The U.S. Navy has roughly 296 ships. The People's Liberation Army Navy now exceeds 370 ships. Numbers are not everything. But capacity matters. And capacity depends on budgets sustained across administrations.
How Does Military Weakness Threaten Trade?
Military weakness threatens trade because the global economy floats on sea lanes that adversaries can disrupt. Approximately 80 percent of global trade by volume moves by sea. The Strait of Malacca, the South China Sea, and the Persian Gulf are chokepoints that China, Iran, and other hostile powers study carefully. The U.S. Navy's fleet size has fallen by more than 100 ships since 1990 while the missions assigned to it have multiplied.
The May 2026 tensions near Taiwan illustrated the point. Chinese military exercises around the island disrupted commercial shipping routes for three consecutive days. Lloyd's List reported that container traffic through the Taiwan Strait dropped by 18 percent during the drills. Insurance premiums for vessels transiting the region rose immediately. American consumers may not see those costs directly. They appear as higher prices for electronics, auto parts, and manufactured goods imported from East Asia.
Free trade requires a security guarantor. That guarantor has been the United States since 1945. If the Navy lacks the hulls to patrol the Indo-Pacific, the choice will not be between cheap goods and expensive defense. It will be between expensive goods and no goods at all. Deterrence is cheaper than war. And war is cheaper than surrender.
What Would a Serious Conservative Defense Economy Look Like?
A serious conservative defense economy would align procurement with industrial policy rather than treating them as rival agendas. The Trump administration's 2025 executive order on shipbuilding called for a 355-ship Navy and directed the Pentagon to prioritize domestic suppliers. The order also instructed the Office of Management and Budget to identify defense supply chains dependent on Chinese components. By May 2026, the Defense Department had reported that roughly 8 percent of critical defense components rely in some way on Chinese rare earth processing.
This is an economic vulnerability and a national security vulnerability. China controls roughly 60 percent of global rare earth mining and nearly 90 percent of processing capacity. The United States has rare earth deposits in Wyoming, California, and Texas. We do not mine and refine them at scale because environmental permitting and capital uncertainty have made domestic production uncompetitive. A conservative defense economy would streamline permitting for strategic minerals, fund domestic processing facilities, and use Defense Production Act authorities to guarantee purchase commitments.
The same logic applies to munitions. The war in Ukraine demonstrated that modern conflicts consume precision munitions at rates far exceeding pre-war stockpiles. The United States sent Ukraine more than 2 million 155mm artillery shells between 2022 and 2024. Those transfers exposed low production capacity. Monthly shell production has since increased to roughly 55,000 rounds, up from 14,000 in 2022. But that is still below what a major conflict would require. Capacity cannot be conjured overnight.
Defense Spending Is Fiscal Discipline, Not Fiscal Waste
Conservatives should be skeptical of waste in every federal department, including defense. The F-35 program has cost taxpayers more than $1.7 trillion over its lifecycle. Audits have repeatedly identified accounting failures at the Pentagon. Skepticism is healthy. But blanket cuts to defense spending are not fiscal discipline. They are a gamble with the nation's security and prosperity.
The fiscal 2027 debate will test whether Republicans understand the difference. The House Armed Services Committee began markup in May 2026 with competing pressures. Defense hawks want more ships and missiles. Budget hawks want lower topline numbers. The correct conservative position is to demand efficiency, eliminate redundant programs, and fund the capabilities that deter major war.
Economic strength and military strength are not separate pursuits. They are the same pursuit viewed from different angles. A nation that cannot build ships cannot secure trade. A nation that cannot secure trade cannot sustain prosperity. The budget Congress writes this summer will answer a simple question: does the United States still intend to be both wealthy and free? The answer should be yes.
