The Defense Production Act

The DPA has a compelling rationale. The government’s most fundamental responsibility is to provide for national security, and that responsibility entails ensuring the military has access to the materials, technologies, and services necessary to perform its mission. Yet this obligation must be balanced against the need to preserve a market-based economic system in which private actors, rather than the state, determine the allocation of resources.

The DPA, properly understood, exists between these two imperatives as a limited exception to normal market operations, justified by genuine limitations of markets in addressing certain defense-critical needs. But it is no longer operating within that bounded space. Through a combination of statutory amendments, executive interpretation, and the accumulating weight of precedent, the law has expanded well beyond its original architecture. What was once a targeted mechanism for military readiness now increasingly functions as a general-purpose lever of industrial policy, invoked to address everything from infant formula shortages to clean energy manufacturing and offshore oil production. The definition of “national defense” that animates the law has been stretched to accommodate these uses, but the definition’s elasticity comes at the expense of clarity of purpose.

This essay examines the DPA’s origins, traces the evolution of its authorities, and analyzes the institutional and political dynamics that have driven its expansion. It argues that the DPA’s current trajectory risks transforming the law into a standing mechanism for government intervention across a broad range of industries—if it has not already done so—with real costs to economic efficiency, political accountability, and the integrity of the law itself. The essay concludes with a set of reforms aimed at restoring the DPA’s focus without eliminating its essential function.

The stakes of getting this wrong are serious. Concerns about the DPA’s breadth have repeatedly surfaced in reauthorization debates spanning decades. As former Senate Banking Committee Chairman Phil Gramm warned during a 2001 DPA reauthorization hearing, “The Defense Production Act is the most powerful and potentially dangerous American law, in my opinion.” That warning deserves renewed attention.

The Korean War began on June 25, 1950, when North Korean troops crossed the 38th parallel and the United States entered the conflict two days later. On July 19, 1950, in a message to Congress, President Harry S. Truman called for legislation granting new powers to prosecute the war and meet national defense needs:

The request wasn’t unprecedented. Truman and the United States were less than five years removed from the end of World War II. During the conflict, the US government had been granted sweeping economic powers through the First War Powers Act of 1941 and Second War Powers Act of 1942 (which included presidential authority to mandate that deliveries of certain goods to the government be granted higher priority than all other contracts entered into by a US government contractor). Similarly, during World War I, President Woodrow Wilson created both the War Industries Board, with duties that included setting production priorities, and a National War Labor Board.

On July 19, 1950, the same day that Truman sent his message to Congress, the legislation was introduced that would ultimately become the Defense Production Act. Following substantial revisions, it was signed into law less than two months later on September 8, 1950.

As originally enacted, the DPA consisted of seven titles:

• Title I—Priorities and allocations: Authorized the president to require that defense-related contracts take priority over all others and to allocate scarce materials and facilities as needed for national security.
• Title II—Authority to requisition: Empowered the president to seize privately owned equipment, supplies, or facilities for national defense when no other means of obtaining them exists, upon payment of just compensation.
• Title III—Expansion of productive capacity and supply: Authorized the government to guarantee loans, make direct loans, and purchase raw materials to encourage private businesses to expand industrial capacity and production in support of defense needs.
• Title IV—Price and wage stabilization: Granted the president authority to stabilize prices, wages, and salaries to prevent inflation and economic dislocation caused by the wartime diversion of resources.
• Title V—Settlement of labor disputes: Established mechanisms for resolving labor disputes that could threaten defense production, including presidential intervention and mediation procedures.
• Title VI—Control of consumer and real estate credit: Authorized the Federal Reserve and other agencies to impose controls on consumer installment credit and real estate lending to curb inflationary spending during the defense buildup.
• Title VII—General provisions: Set out definitions, administrative authorities, reporting requirements, and limitations on the act’s powers, including a two-year expiration date and protections against conflicts of interest.

Several titles proved to be immediately controversial. Businesses organized vigorously against Title IV’s measures, denouncing them as “un-American.” They successfully lobbied Congress in 1951 to weaken the measures through the Capehart Amendment, which allowed companies to pass on cost increases to consumers. Title II’s authority to requisition private property generated similar opposition as an overreach of executive power.

Congress curtailed the titles as part of a 1953 amendment, with Titles IV and V eliminated in April 1953 and Titles II and VI in June 1953. What remained, Title I’s prioritization, Title III’s capacity expansion, and Title VII’s general provisions, form the law’s beating heart today. Also included were sunset provisions requiring periodic reauthorization, which Congress has done at least 53 times since 1950. Those reauthorizations, perhaps an opportunity to reconsider the law’s wisdom, have instead provided recurring opportunities for its expansion.

Any assessment of the DPA’s evolution must begin with the statutory definition of “national defense” that determines the law’s outer boundary. In its original form, national defense was defined as the operations and activities of the armed forces or any government agency “directly or indirectly and substantially concerned with the national defense.” The emphasis was on direct military application, with the “substantially” qualifier limiting the DPA’s scope.

Congress has since amended that definition repeatedly. Amendments enacted in 1992, 1994, and 2003 widened the term to encompass energy production and construction, critical infrastructure protection, homeland security, stockpiling, and space activities, as well as “any directly related activity.” Emergency preparedness activities conducted under the Stafford Act, which outlines the federal framework for responses to national disasters and terrorism, were also incorporated. The undefined phrase “directly related activity” significantly expanded the universe of possible DPA uses by providing government actors with considerably greater latitude to leverage the law’s authority.

This definitional drift has proceeded largely without sustained public attention. Each individual amendment has been justified by a specific and often plausible concern, such as critical infrastructure vulnerability, post‑9/​11 homeland security needs, and supply chain resilience—and congressional debate did occur. But the cumulative effect has been to transform a carefully bounded definition, limited to situations in which the government has legitimate authority and reason to intervene, into one that can accommodate almost any intervention a determined executive chooses to pursue. Jeb Nadaner, a former deputy assistant secretary of defense for industrial policy, described this in congressional testimony as the “steady and seemingly inexorable expansion of the scope of DPA and the promiscuous growth in the definition of ‘national defense.’”

This expansion is hardly the product of solely executive opportunism. Congress has been a willing architect of the DPA’s broadened scope, repeatedly amending its definition of national defense to accommodate new priorities. The problem is not that the executive branch has exceeded its statutory authority—in most cases, it hasn’t—but that Congress has delegated that authority too broadly without adequate limiting principles or oversight mechanisms. The case for reform is therefore directed primarily at Congress, not the executive branch alone. Indeed, the executive branch’s proclivity to maximize the discretionary power granted by Congress across many domains is well documented and should be a default assumption.

Although the DPA is often discussed as a single instrument, its two most consequential authorities, Titles I and III, operate in fundamentally different ways. Title I reflects the DPA’s original purpose most faithfully. Its prioritization authority allows the federal government to issue “rated orders” requiring contractors to treat certain defense contracts as higher priority than other orders. Crucially, this authority only reallocates existing productive capacity toward defense needs rather than mandating new production capacity or output levels as Title III can. Title I is a tool for coordination, not planning. Although its interventions do impose costs and market distortions, they are incidental rather than deliberate and inherently time limited.

Title III is different. Rather than reallocating existing capacity, it expands or reshapes capacity through financial incentives—loans, loan guarantees, purchase commitments, and direct investments—used to encourage firms to enter or expand production in designated sectors. While Title I works within the market’s existing structure, Title III seeks to alter market outcomes by directing capital toward specific industries or technologies. Combined with an expansive definition of national defense, this is industrial policy in the term’s most precise sense.

The DPA does impose conditions on Title III use. Financial incentives must represent the “most cost effective, expedient, and practical alternative” for meeting an identified federal need, and loan guarantees are available only to recipients who cannot otherwise obtain credit on “reasonable terms.” These requirements reflect legislative awareness that Title III carries greater risks of abuse and inefficiency than Title I does, as well as an intent to limit its use accordingly. In practice, however, these conditions are loosely worded and have been liberally applied. Title III has driven the DPA’s most significant expansions of use in recent years.

To be clear, Title I is not immune to overreach. For instance, compelled production questions arise under Title I, not Title III. But Title III poses the more significant long-term structural risk, as its interventions can permanently reshape industries by altering investment patterns, creating dependencies on government support, and picking winners in ways that may not reflect genuine comparative advantage. Seeking to reshape industries is arguably Title III’s point, and that can all be done without Congress.

Although the DPA had been gaining strength for years, the COVID-19 pandemic arguably marked a new era in the law’s application. That era can be understood in three phases: emergency health uses during the pandemic itself, industrial policy uses that followed under both administrations, and novel compelled-access uses involving digital technologies that are still unfolding.

When confronted with the deadly new virus, the first Trump administration initially favored letting market forces handle matters. “We’re a country not based on nationalizing our business,” said President Trump in March 2020. But facing a rising death toll and mounting political pressure, the administration changed its tune only weeks later. It invoked Title I of the DPA to require General Motors (GM), General Electric (GE), Philips, and others to prioritize government contracts for ventilators and subsequently used Title III to expand production capacity for respirators and ventilator filters.

Title I’s prioritization authority meant that federal contracts jumped to the head of the line at the expense of others, including states scrambling for their own supplies. “It’s like being on eBay with 50 other states, bidding on a ventilator,” said New York Governor Andrew Cuomo in March 2020, as states found their own orders intercepted and diverted by federal authorities.

Simultaneously, the Coronavirus Aid, Relief, and Economic Security Act, or CARES Act, appropriated $1 billion to the DPA Fund and waived several key Title III oversight requirements for two years. Congress did not merely fund an expanded DPA but also temporarily dismantled the safeguards meant to constrain it.

The results were instructive. By August 2020, more than 94,000 ventilators had been delivered to the federal stockpile. But the approach to treating COVID-19 changed during the months it took companies to retool, and the vast majority sat unused in a strategic reserve (though some excess inventory was by design, given the genuine uncertainty about the pandemic’s trajectory at the time).

A subsequent ProPublica investigation alleged that the White House may have paid up to $500 million more than necessary for the ventilators it acquired. Meanwhile, the administration announced a $765 million DPA loan for camera film company Eastman Kodak to manufacture pharmaceutical ingredients, but the deal collapsed within weeks amid a Securities and Exchange Commission investigation into suspicious stock trading.

The effects of DPA-driven prioritization also extended beyond America’s borders. When the Biden administration invoked the DPA to secure vaccine inputs in early 2021, the Serum Institute of India, the world’s largest vaccine manufacturer, warned that production lines turning out more than 160 million doses a month would grind to a halt within weeks unless America supplied 37 critical items. A domestic prioritization law had, in effect, functioned as an export restriction because it left little capacity for foreign buyers to draw on.

Yet even as the pandemic receded, the Biden administration’s appetite for DPA invocation did not. Rather, it simply shifted from emergency health measures to broader industrial policy. But this was hardly breaking new ground. In April 2020, the Trump administration provided $50 million to the Austal shipyard in Mobile, Alabama—billed as part of its COVID-19 response—so that the facility could boost its steel shipbuilding capabilities (after previously specializing in aluminum construction).

A March 2022 presidential determination authorized Title III support for domestic mining and processing of materials for large-capacity batteries in the automotive and e‑mobility sectors. The Biden administration explained that the move signaled its commitment to a “robust, resilient, sustainable, and environmentally responsible domestic industrial base to meet the requirements of the clean energy economy.”

The defense rationale was strained. A 2021 report commissioned by the Department of Defense had concluded that all-electric ground combat vehicles were “not practical in the foreseeable future” through 2035. The June 2022 granting of DPA authority to the Department of Energy to accelerate clean energy manufacturing also raises eyebrows. Beyond the announcement’s strained linkage to national security, it highlighted that the move would help in “reducing energy costs for American families” and “creating more good-paying union jobs.”

That same spring, DPA authority was delegated to the Department of Health and Human Services to prioritize infant formula ingredients in response to a domestic shortage. Of the $500 million in DPA funding appropriated through the passage of the Inflation Reduction Act in August 2022, none went to core national defense needs. Instead, $250 million alone was directed toward electric heat pumps.

Another notable Biden administration invocation of the DPA occurred in October 2023, through an executive order that required leading AI developers to share safety test results with the government. This demonstrated that whether the DPA could reach AI systems was not a future hypothetical but an active policy consideration.

The second Trump administration, meanwhile, has further underscored the bipartisan nature of the executive branch’s appetite for an expansive DPA. Since taking office in 2025, the administration has issued presidential determinations authorizing Title III awards for tungsten, scandium, and gallium, and a February 2026 executive order designated elemental phosphorus a scarce defense material partly because of its role in producing glyphosate-based herbicides. In addition, Secretary of Defense Pete Hegseth has reportedly explored whether the DPA could compel AI company Anthropic, over its objections, to provide access to its AI models.

On April 20, 2026, the Trump administration issued five presidential determinations pursuant to Section 303 of the DPA, covering coal supply chains, large-scale energy infrastructure, grid equipment, domestic petroleum, and natural gas and liquefied natural gas (LNG) capacity. Taken together, Figure 1 shows that they represent an unusually sweeping deployment of DPA Title III authority, with five sectors of the domestic energy economy designated as essential to national defense. Each determination found that the relevant sector constituted an “industrial resource essential to national defense” that private industry could not address without federal action. Each also waived the statutory prerequisites for expedited deployment of loans, loan guarantees, purchase commitments, and cost-sharing arrangements.

The boilerplate finding of necessity, repeated five times in a single afternoon, illustrates how the DPA’s preconditions have become procedural formalities rather than substantive constraints. The waiver of the statutory prerequisites meant to serve as a market failure screen suggests a disconcerting awareness that those conditions might not be satisfied on their merits.

Notably, the determinations did not stand alone. They built on Executive Order 14156, which declared a “National Energy Emergency” on January 20, 2025, and appear to be designed to channel the $200 billion in loan authority that Congress appropriated through the July 2025 budget reconciliation law. The DPA determinations function, in effect, as the mechanisms by which that capital can be deployed more rapidly and to a broader range of projects than normal program structures would allow. The pattern illustrates how executive emergency powers compound one another, with each invocation providing the foundation for the next. Each step may appear individually defensible, but the cumulative result is a transformation of the law’s effective scope.

Perhaps the most arresting recent example of DPA overextension involves a bankrupt budget airline. In late April 2026, the Trump administration began exploring the DPA’s use to rescue Spirit Airlines, which had declared bankruptcy twice in two years. The reported plan envisioned lending Spirit approximately $500 million and using the airline’s excess capacity to transport troops and military cargo. The national security rationale read as a tacked-on afterthought to justify the DPA’s invocation. The primary driver was plainly job preservation, not military readiness, placing the Spirit episode in the same category as the Eastman Kodak DPA loan of 2020. Although the government ultimately opted not to proceed, the episode further illustrates the DPA’s susceptibility to abuse.

These examples reveal not only a law being stretched at the margins but also a governing tendency to reach for the DPA because it offers expediency, executive discretion, and the political legitimacy of a “national security” framing. Episodes such as five major sectors of the energy economy and a bankrupt airline, all subject to or considered for DPA interventions in a single week, represent the logical end point of the drift this essay has traced.

For the executive branch, the DPA’s attractions are straightforward. But Congress has its own incentives to tolerate this expansive approach. Reauthorizing the DPA is less politically costly than enacting specific legislation, and effectively delegating difficult policy decisions to the executive via the DPA while retaining the ability to criticize specific uses if they prove unpopular has its attractions. Agencies implementing the DPA, meanwhile, have institutional interests in maintaining and expanding their authority, with Title III funding creating opportunities for new programs and industry partnerships that expand agency missions and budgets.

The result is policy drift through precedent. Each new use of the DPA, ostensibly justified by immediate circumstances, establishes a precedent for future applications. The ventilator contracts of 2020 make the infant formula intervention of 2022 easier to justify, and the battery materials determination of 2022 makes the phosphorus designation of 2026 easier to defend. The statutory text does not change, but its effective boundaries shift with each successive invocation.

The number of active Title III projects reported by the Department of Defense tells the story, increasing from 4 in 1994 to 37 in 2013 and 56 in 2024 (Figure 2). The funding trajectory is equally striking. From fiscal year 2010 through FY2019, Congress appropriated approximately $952 million to the DPA Fund. From FY2020 through FY2025, Congress appropriated at least $4.4 billion, which is more than four times as much in half the time.

Testifying before Congress in May 2024, the Pentagon’s Assistant Secretary for Industrial Base Policy Laura Taylor-Kale pointed out that since the DPA’s last reauthorization in 2018, Title III appropriations had increased from an average of about $70 million a year to about a billion dollars annually. Figure 3 makes the additional financial heft plain.

The security rationale for a share of this expansion is not entirely without merit. The concentration of critical-mineral processing in China is an understandable concern, and many technologies are dual-use. But if national security includes supply chain resilience—defined as domestic production capacity of any item conceivably linked to the defense supply chain or deemed strategically important—then the DPA’s reach has few effective limits. As Nadaner stated in his congressional testimony: “DPA awards must be anchored by compelling military needs and critical national infrastructure priorities. If everything is a priority, effectively nothing is.”

While a plausible chain of reasoning connects most contested DPA uses to national defense, the problem is not that these connections are fabricated but that they are too thin to function as meaningful constraints. If a sufficiently creative chain of reasoning can link any domestic economic priority to national security, then the DPA becomes a mechanism for bypassing the normal legislative process whenever the executive finds it convenient.

Although some costs of this dynamic are obvious, others are more subtle. By offering a ready-made tool for intervention, the DPA reduces pressure to address the underlying policy failures that created the problem in the first place. The infant formula crisis offers a perfect example. American mothers’ struggle to nourish their babies directly resulted from protectionist policies and government red tape that prevented market forces from speeding relief to store shelves. Rather than addressing the root cause, however, the DPA allowed the problem to be temporarily papered over. The ingredients for a future crisis still lurk.

As former Cato Institute Senior Fellow Eric Gomez has observed, the DPA “allows us to punt on bigger questions of what could either fix this in a more sustainable way, or get us to make some bigger changes that we ought to be making in our policies.” A historical study commissioned by the US Army War College concluded that the DPA’s expanding scope had “weakened its ability to prepare and mobilize the nation for a military conflict and turned it into a panacea to solve national emergencies.” And Tanya Das, a former Department of Energy official, has warned of another overlooked downside of executive discretion: Invoking the DPA for politically polarizing ends risks making it less effective.

While the legal and constitutional concerns raised by the DPA’s expanding scope are well-documented, the economic costs that accumulate as the law is deployed for purposes removed from genuine military necessity are relatively overlooked. Although they do not appear on any federal ledger, they are nonetheless real.

Chief among them is capital misallocation. Title III interventions redirect financial resources toward industries and projects that private capital markets have chosen not to prioritize on comparable terms. Such choices are not taken lightly, reflecting assessments of risk, return, and comparative advantage embedded in market competition’s pricing signals.

When the government overrides those signals, it shifts resources from their highest-valued uses to politically selected ones. The costs, such as the jobs not created in sectors that lost out to subsidized competitors, leave no paper trail but are no less real. If done to meet genuine national security needs, the trade-off may be justified. But using the law to bolster coal supply chains, heat pumps, or a struggling budget airline is simply industrial policy in disguise.

The DPA’s expansion also generates pervasive uncertainty, which is economically damaging in its own right. Firms that operate in or adjacent to sectors that might be designated as national security priorities cannot know whether their competitive position will be disrupted by a presidential determination, rated order, or compelled-access demand. They cannot know whether their supply chain will be redirected, their credit market crowded out, or their technology compelled to be shared with the government. This uncertainty shortens planning horizons, thereby depressing investment in long-term projects and distorting corporate strategy in ways that reduce aggregate efficiency. The more expansive the DPA’s potential reach, the more pervasive this uncertainty becomes.

Dependency is a related distortion. Once an industry has been reshaped by Title III support, including capacity built, loans extended, and purchase commitments made, it acquires an interest in continuing that support. And the dependency runs in both directions. Agencies that have committed loans and purchase guarantees to specific firms develop institutional stakes in their success and a corresponding reluctance to allow them to fail. No administration wants to preside over the collapse of a company it publicly backed with emergency authority. The result is a ratchet: Government support creates enterprises dependent on that funding; those enterprises create pressure for continued support; and the portfolio of DPA-dependent industries grows with each successive administration.

These economic costs would be tolerable if the DPA produced commensurately needed industrial capacity. That may be the case in limited, well-defined circumstances. But subsidizing items such as petroleum pipelines, coal stockpiles, and bankrupt domestic airlines brings no offsetting national security benefits. In those cases, the costs are simply borne, the resources simply misallocated, and the market signals simply overridden, all in service of the executive branch’s economic preferences.

Reforming the DPA does not mean eliminating it. The law continues to serve functions that can prove useful in genuine national security emergencies. But it is imperative that the law be reformed to restore focus and discipline. The following are proposals to achieve that vision.

Narrow the definition of national defense. Under existing statute and judicial interpretation, the DPA’s definition of national defense is broad, and many of the uses critiqued in this essay are legally defensible under that definition. But the current standard imposes no meaningful constraint on executive discretion.

Congress should require that activities supported under the DPA meet a clear, demonstrable nexus to military operational readiness, meaning direct support for military operations, provision of critical inputs for defense systems, or mitigation of clearly identified supply chain vulnerabilities with documented effects on military capability. Phrases such as “any directly related activity” should be removed or replaced with language that imposes genuine limiting force. Invocation of the DPA should be done within narrow, defined boundaries, and any expansions of its scope should be made through explicit congressional action rather than implicit executive interpretation.

Establish a rigorous market failure standard and strengthen oversight. Title III authorities should be used as tools of last resort. Before invoking them, agencies should be required to conduct and publish a market failure analysis demonstrating that private capital will not address the identified shortfall without government intervention and that direct financial incentives are superior to alternative approaches, including tax incentives, regulatory reform, and the use of allied industrial bases. This is not an onerous requirement. If a genuine case for intervention exists, making it should not be difficult. Agencies that fail to demonstrate compliance with these standards should become ineligible to access DPA funds for the proposed action.

On oversight, the existing architecture offers a cautionary example. Congress created the Defense Production Act Committee (DPAC) in 2009 to serve as a cabinet-level coordinating body for DPA activities. But it never fully launched. An executive director was never hired; chairmanship was subdelegated to the Federal Emergency Management Agency administrator as a collateral duty; and Congress scaled back its mandate in 2014. A 2021 Congressional Research Service brief found that “DPAC’s principal function appears to be developing its annual report to Congress”; as of a November 2024 study, the report for calendar year 2020 remained the most recent publicly available. The lesson is that oversight mechanisms without dedicated leadership and a meaningful mandate do not constrain executive discretion but serve as mere window dressing.

Compounding the challenge, DPA contract awards are kept confidential, as the act has traditionally been used for military technology. That practice, however, is poorly suited to a law now routinely invoked for civilian economic purposes. Congress should require detailed public reporting—regularly updated on a public website—on each material use of DPA authority, including the specific legal basis, identified defense need, expected benefits, and criteria used to select recipients.

For nonemergency applications of Title III funding above a specified threshold, a legislative fast-track approval process must be established to ensure that material interventions receive legislative scrutiny. Emergency uses should remain available without prior approval but should be narrowly defined and subject to mandatory evaluation by the Government Accountability Office after the fact.

Reorient the DPA toward barrier removal. Many constraints on the defense industrial base are the result of regulatory and bureaucratic barriers imposed by government, not insufficient government funding. As the White House acknowledged in a March 2025 executive order on domestic mineral production, “Overbearing Federal regulation has eroded our Nation’s mineral production.” According to the National Mining Association, securing permits to open a mine in the United States takes nearly 10 years compared to two or three in Canada and Australia.

One reform worth considering is refashioning the DPA itself as a mechanism for identifying and suspending specific government-imposed obstacles to defense-critical production. Workforce constraints offer a useful example. As Nadaner noted in his testimony, “It is no good for a company to get a DPA Title III award but then be unable to find the advanced hardware trades and technical experts.” To ensure access to skilled labor, Congress could allow DPA recipients to invoke narrowly defined exceptions to existing work visa programs for specialists working on DPA-funded projects in certified shortage occupations.

Numerous other possibilities come to mind. Using the DPA as a tool to remove or overcome other regulatory obstacles, such as expediting mining permits or suspending the Jones Act on a long-term basis to ensure the viability of domestic supply chains, also deserves consideration.

Remove social engineering from defense procurement, clarify compelled production, and address the precedent problem. Current DPA language directs the president to give preference to small businesses located in areas of high unemployment. Although politically appealing, such criteria produce inefficiencies and should be removed. Congress should also clarify the limits on the government’s authority to compel production in sectors where the relevant “product” is not a physical good. Protecting property rights in high-tech industries is essential, particularly as AI and other digital technologies become increasingly relevant to national security.

Finally, Congress should interrupt the accumulation of precedent by specifying that a DPA invocation in one context does not constitute authorization in materially different contexts. Strengthening sunset provisions so that novel applications require affirmative reauthorization rather than persisting by default presents another sensible step.

The Defense Production Act was designed to address a specific problem: Ensuring that the extraordinary demands of military mobilization are met. It was never intended to serve as a standing, general-purpose instrument for peacetime economic management. The distinction matters because laws that lack clear purposes become tools in search of justifications, which executive agencies can be expected to reliably generate.

The DPA is now in that condition. Its definition of national defense has expanded to encompass much of the domestic economy. Its Title III authorities are routinely deployed for objectives including the production of clean energy and offshore oil that are more accurately described as domestic economic priorities than defense necessities. The precedents set by each administration, regardless of party, make the next expansion easier to justify and harder to contest (Table A1).

The reforms proposed here are not radical. They ask Congress to do what it should have been doing throughout the law’s evolution: clearly define the boundaries of executive authority, require those boundaries to be respected, and ensure that significant economic interventions are subject to democratic accountability. These are modest demands. The fact that meeting them would represent a significant change in how the DPA operates is itself a measure of how far the law has drifted from its foundations.

A DPA that is genuinely limited to defense production would be a more powerful instrument, not a weaker one. Clarity of purpose concentrates resources and attention on problems the law was designed to solve—and can solve. The alternative of a DPA that can be invoked for almost anything is not one that bolsters the country’s security and well-being but undermines it by, among other matters, redirecting resources to less valuable uses and unduly politicizing decisions that should be made strictly based on national security concerns.

The following table documents selected invocations and uses of the DPA discussed in this essay, organized chronologically by administration. The “NS nexus” column reflects the level of directness in the national security rationale: Direct (clear military operational necessity), Moderate (plausible but indirect defense connection), or Attenuated (thin or contested national security justification).
