In January 2009, Barack Obama entered the White House promising to change the relationship between government and private industry. One of his priorities was closing the revolving door that allowed lobbyists to become government officials and former public servants to profit from the industries they had overseen. Yet one of his administration’s earliest appointments demonstrated just how difficult that promise would be to fulfil.
William J. Lynn III had served as under secretary of defense during the Clinton administration before joining Raytheon, one of America’s largest military contractors. He became a senior vice president and registered lobbyist for the company. Despite that background, Obama nominated him as deputy secretary of defense, requiring an ethics waiver to accommodate an appointment that conflicted with the administration’s new restrictions.
The administration argued that Lynn possessed expertise the Pentagon needed. Critics saw the appointment as evidence that Washington’s most important institutions remained dependent on the industries they were supposed to regulate. Both positions revealed something important about the American military-industrial complex.
The military-industrial complex is not simply a collection of weapons manufacturers making money from warfare. It is an interconnected system of military leaders, government agencies, contractors, politicians, lobbyists, investors, universities, research institutions and communities whose interests have become increasingly dependent on one another.
Its power developed over decades. World War II established an unprecedented partnership between government and private industry, the Cold War made that relationship permanent, and subsequent economic and political decisions concentrated enormous influence among a relatively small number of companies. Understanding how that happened reveals why military spending can be so difficult to challenge, even when the government itself acknowledges serious problems.
From Wartime Factories to a Permanent Arms Industry
The United States had military contractors long before World War II. Private businesses had supplied weapons, ships, ammunition and other equipment for generations, while government arsenals and shipyards maintained important production capabilities. What changed during the twentieth century was the scale of military production and the permanence of the relationship between the armed forces and private manufacturers.
Before World War II, American military demand generally expanded during conflicts and declined when wars ended. Companies that primarily served civilian markets could redirect their factories towards military production when necessary. Once peace returned, armies demobilised, government orders contracted and manufacturers resumed producing commercial goods.
World War II transformed that arrangement. The United States needed to equip millions of troops fighting across Europe, North Africa, Asia and the Pacific, requiring an industrial mobilisation unlike anything the country had previously attempted. Automobile manufacturers produced tanks, aircraft engines and military vehicles, while shipyards, steel companies, electronics firms, universities and laboratories contributed to a vast interconnected production system.
President Franklin D. Roosevelt established the War Production Board in 1942 to coordinate civilian industrial resources for military purposes. The government allocated scarce materials, established production priorities, helped finance industrial expansion and worked directly with corporate executives and engineers. The boundaries between government planning and private manufacturing became less distinct because national survival depended on their cooperation.
This industrial mobilisation was essential to Allied victory in World War II. It demonstrated that American manufacturing capacity could be converted into extraordinary military power when government resources, scientific research and private industry operated together. It also created institutions, relationships and expectations that would survive the conflict.
When the war ended in 1945, the United States demobilised millions of service members and reduced military expenditure dramatically. However, it did not completely return to its earlier defence arrangements. Nuclear weapons, strategic aviation, advanced electronics and emerging international commitments made military preparedness increasingly dependent on specialised technologies that could not be produced overnight.
The emerging confrontation with the Soviet Union reinforced this transformation. During the Cold War, the United States maintained a substantial military establishment, developed global alliances and invested continuously in nuclear weapons, aircraft, submarines, missiles and surveillance systems. The Korean War strengthened the argument that the country needed industrial capacity capable of responding quickly to major military threats.
For businesses, continuous demand changed the economics of military production. Companies could justify maintaining specialised factories, engineering teams and research programmes because defence spending was no longer expected to disappear after every conflict. Boeing expanded its military aviation operations, Lockheed became increasingly associated with advanced aircraft and missile systems, and General Dynamics developed major businesses involving submarines, aircraft and armoured vehicles.
Military equipment also became more technologically demanding. A conventional truck could be manufactured by numerous commercial companies, but nuclear submarines, intercontinental missiles and sophisticated fighter aircraft required specialised infrastructure, classified knowledge and years of research. The government increasingly depended on businesses whose capabilities could not easily be replaced.
A relationship originally strengthened by the emergency of global warfare had become a permanent feature of American economic and political life.
What Eisenhower Feared—and What He Did Not
Few American presidents understood military power as intimately as Dwight D. Eisenhower. He had commanded Allied forces in Europe during World War II, served as NATO’s first supreme commander and governed the United States during some of the Cold War’s most dangerous years.
In his farewell address on January 17, 1961, Eisenhower warned Americans about the growing influence of what he called the military-industrial complex. His concern was not that military preparedness was inherently unnecessary or that private defence contractors should cease to exist. He explicitly acknowledged that the country needed a permanent armaments industry in an era of global military threats and rapidly changing technology.
What troubled Eisenhower was the political and economic influence that accompanied this permanent establishment. The United States had developed an enormous military organisation supported by a specialised industrial system whose activities reached into Congress, government agencies, universities, scientific research and communities across the country.
He urged Americans to guard against the acquisition of “unwarranted influence, whether sought or unsought,” by the military-industrial complex. That distinction between deliberate and unintended influence is central to understanding his warning.
A contractor does not need to bribe politicians to influence military spending. A member of Congress may genuinely believe that a local weapons factory provides essential employment, while military officers may sincerely believe that a particular programme is vital to national security. Government agencies may depend on contractors because those businesses possess technical expertise that the public sector cannot readily reproduce.
Each participant can pursue an understandable objective while collectively sustaining a system that becomes increasingly resistant to scrutiny.
Eisenhower feared that the concentration of military, industrial and political interests could influence which decisions appeared reasonable, which programmes seemed indispensable and which alternatives received serious consideration. A democratic government might gradually lose the ability to evaluate military requirements independently of the institutions already benefiting from them.
His warning was therefore about more than excessive expenditure or corporate corruption. It concerned the possibility that an establishment created to protect national security could accumulate enough institutional power to distort democratic decision-making.
The Pentagon’s Last Supper and the Death of Competition
For decades, the Cold War supported an enormous American defence industry. The Soviet Union provided a continuing strategic competitor, while successive governments funded increasingly expensive aircraft, missiles, submarines, satellites and other military systems.
Then the Soviet Union collapsed in 1991.
The United States emerged as the world’s dominant military power, and policymakers began discussing a potential peace dividend. Defence spending declined as a share of the economy, military requirements were reassessed and contractors faced the possibility that the government would no longer sustain the industrial capacity developed during decades of superpower competition.
For the Pentagon, this created a serious dilemma. Maintaining numerous competing manufacturers was expensive, but allowing too many companies to disappear could weaken the country’s ability to develop and produce advanced weapons.
In 1993, Defense Secretary Les Aspin and Deputy Secretary William Perry met with senior defence-industry executives at a dinner that became known as the Pentagon’s “Last Supper.” The message was that the government could no longer support the existing number of major contractors. Industry consolidation was encouraged as a way to eliminate duplicated facilities, reduce overhead costs and preserve strategically important manufacturing capabilities.
The economic logic was understandable. Companies facing reduced orders needed to restructure, and the government wanted a smaller industrial base that could survive declining expenditure without losing critical technologies. Consolidation was not simply an unexplained attempt to enrich large corporations; it responded to a genuine post-Cold War problem.
However, its long-term consequences were profound.
Lockheed merged with Martin Marietta in 1995, creating Lockheed Martin. Northrop acquired Grumman in 1994, forming Northrop Grumman. Boeing acquired McDonnell Douglas in 1997, while other companies merged, sold their defence divisions or withdrew from military production.
The industry that emerged was dramatically more concentrated than the one that had existed during the Cold War.
According to the Pentagon’s 2022 assessment of competition in the defence industrial base, the number of major aerospace and defence prime contractors fell from 51 to five. The department also documented reductions in particular markets, including major suppliers of tactical missiles, military aircraft and satellites.
These figures describe historically defined categories rather than suggesting that every American defence product is manufactured by only five companies. Nevertheless, they illustrate the substantial decline in the number of businesses capable of competing for the military’s largest programmes.
Consolidation offered efficiencies, but it also removed alternatives. When the Pentagon needed a new fighter aircraft, submarine or complex weapons system, fewer companies possessed the technical expertise, manufacturing facilities and financial resources required to compete.
In an ordinary market, an unhappy customer can switch suppliers. The United States government increasingly found itself purchasing indispensable military capabilities from companies it could not easily replace.
That dependence became one of the foundations of the modern military-industrial complex.
Why a Defense Contract Can Become a Decades-Long Dependency
Defence contracting operates differently from most commercial markets because the government is often the principal customer, the products are extraordinarily specialised and the costs of failure can be enormous.
A consumer-electronics manufacturer can develop a product, release it, examine customer reactions and improve its next version. A contractor developing a nuclear submarine or advanced fighter aircraft may need billions of dollars and many years of engineering before a usable platform exists. Some technologies have no meaningful commercial market, making government funding essential from the beginning.
The complexity of these programmes gives established contractors substantial advantages.
Developing advanced weapons requires specialised workers, security clearances, testing facilities, proprietary designs, manufacturing equipment and familiarity with military requirements. New competitors cannot simply construct an equivalent production system and offer the same technology at a lower price.
Even when several companies compete for an initial contract, meaningful competition may decline after the government selects a supplier.
Consider a new fighter aircraft. The initial manufacturer does not merely deliver a finished product and end its relationship with the Pentagon. The aircraft will require replacement parts, software updates, structural repairs, specialised testing, maintenance equipment, training and technological improvements throughout its service life.
Those responsibilities may continue for decades.
The original contractor frequently possesses knowledge and technical data that competing suppliers cannot easily access. Proprietary designs and specialised tools can make it difficult for another business to manufacture compatible components or undertake complex modifications. Even when the government possesses certain technical rights, recreating an alternative supply chain may require enormous investment.
This creates what economists call vendor lock-in.
The government becomes dependent on the company not simply because of an existing contract, but because changing suppliers may threaten military readiness. If a contractor is the only organisation capable of maintaining a critical system, allowing that company to collapse can itself become a national-security risk.
The Pentagon can therefore find itself in the unusual position of needing to sustain companies whose prices or performance it wants to challenge.
Contract structures further influence these relationships.
Under a fixed-price contract, the supplier generally agrees to provide defined goods or services for an established price. Depending on the contract’s terms, the contractor bears substantial responsibility for expenses exceeding its estimate. This gives businesses an incentive to manage costs, although poorly designed fixed-price agreements can create other difficulties when requirements are uncertain.
Cost-reimbursement contracts allocate more financial risk to the government. The contractor receives reimbursement for allowable expenses and may earn an additional negotiated fee. Such contracts can be reasonable for research and development projects where technological uncertainty makes reliable cost estimates impossible.
However, they can also weaken incentives to minimise expenditure, particularly when competition is limited and the government cannot easily abandon the programme.
An important distinction is that federal contracting rules do not simply permit defence contractors to earn a fixed percentage of every additional dollar spent. Federal Acquisition Regulation 16.102 explicitly prohibits cost-plus-a-percentage-of-cost contracting. Permitted cost-reimbursement arrangements have different fee structures, and higher project costs do not automatically produce proportionally higher contractor profits.
The underlying problem is more complicated than a straightforward reward for overspending.
When the government bears much of the financial risk, contractors may face weaker competitive pressures than companies selling directly to consumers. When technical complexity makes estimates uncertain and few alternative suppliers exist, government officials can struggle to determine whether increasing expenditure is justified.
Long development periods introduce another problem: sunk costs.
By the time serious difficulties become apparent, the government may already have invested billions of dollars, trained military personnel, constructed facilities and reorganised future military plans around the expected system. Cancelling it may require abandoning years of work and spending even more money to develop an alternative.
Continuing can seem less damaging than accepting the loss, even when the project’s original assumptions no longer hold.
This combination of limited competition, technical dependence, contractual risk and accumulated investment explains why some defence programmes become extraordinarily difficult to control. The contractor is no longer simply a supplier offering a product. It has become part of the government’s military infrastructure.
The F-35: How Scale, Complexity and Incentives Lock In Cost
Few programmes demonstrate the advantages and dangers of this arrangement more clearly than the F-35 Joint Strike Fighter.
The F-35 was designed to provide three related aircraft variants for the US Air Force, Navy and Marine Corps, replacing several older platforms while sharing important technological components. International partners also became involved, creating a programme intended to benefit from common production, advanced capabilities and economies of scale.
The concept offered considerable strategic advantages.
Rather than developing completely separate aircraft for every military service, the United States could invest in a common family of stealth fighters equipped with advanced sensors, sophisticated communications and the ability to share information across military systems. Allied participation promised greater interoperability and additional production demand.
However, designing different aircraft around shared technology proved far more complicated than the original concept suggested.
The Air Force required a conventional takeoff and landing fighter, the Marine Corps needed a short-takeoff and vertical-landing variant, and the Navy required an aircraft capable of operating from aircraft carriers. Accommodating these requirements while maintaining commonality introduced significant engineering challenges.
The programme encountered delays, software difficulties, design modifications, maintenance problems and rising sustainment expenses.
One particularly consequential decision was to begin producing aircraft while development and testing were still underway. This approach, known as concurrency, was intended to accelerate the arrival of operational aircraft. However, when testing revealed problems, aircraft already manufactured sometimes required expensive modifications.
That meant the consequences of unresolved engineering issues extended beyond development laboratories into the expanding fleet.
The programme’s financial commitments became enormous. A 2024 Government Accountability Office assessment placed projected acquisition and sustainment spending above $2 trillion over the planned life of the American fleet, extending towards 2088.
A figure of that magnitude requires careful interpretation. It is not simply the amount by which the original development budget was exceeded, nor does it represent money already spent. It includes projected expenditures for purchasing, operating, maintaining and supporting aircraft over many decades.
Nevertheless, the scale demonstrates how purchasing advanced military technology creates financial obligations far beyond the initial price of the equipment.
Sustainment has become especially important. The Government Accountability Office reported that estimated lifetime sustainment costs increased substantially as officials reassessed maintenance requirements, planned operations and the resources necessary to keep the aircraft flying.
Higher projected expenditure would be easier to defend if it consistently delivered the required readiness.
Yet the GAO’s 2026 review of F-35 sustainment found that the overall mission-capable rate declined from approximately 67% in fiscal year 2021 to 44% in fiscal year 2025. The full mission-capable rate was approximately 25% in fiscal year 2025, indicating that only a minority of aircraft were available for every mission they were designed to perform.
The distinction matters. An aircraft may be mission-capable for some operations without being ready for its full range of assigned missions. Readiness problems therefore affect the military value received from an expensive fleet, not merely the government’s accounting records.
GAO also identified weaknesses in contractor-performance incentives, including payments that had not produced the intended readiness outcomes. These findings illustrate the difficulty of creating effective accountability when the military depends on specialised manufacturers and sustainment arrangements.
None of this establishes that the F-35 is militarily worthless.
Its stealth technology, sensors, information-sharing capabilities and integration with allied forces offer advantages that older aircraft cannot easily reproduce. The United States and its partners have invested heavily in bases, training, weapons integration and operational plans built around the platform.
That strategic significance makes abandoning the programme difficult.
The Pentagon cannot assess the F-35 solely as an isolated commercial purchase. It must consider whether alternatives could fulfil the same missions, what replacement development would cost, how long it would take and what capabilities might be lost during the transition.
The consequences of cancellation are illustrated by another programme: the VH-71 presidential helicopter.
The United States began developing the VH-71 to replace ageing presidential helicopters, but costs escalated from an estimated $6.5 billion to roughly $13 billion. The programme was cancelled in 2009 after substantial expenditure without delivering the originally intended operational replacement.
The cancellation showed that even major defence projects are not absolutely immune to termination. It also demonstrated how much money and industrial effort can be lost when technological requirements, programme management and costs become unsustainable.
The F-35 involves a much larger operational commitment. Hundreds of aircraft, international partners, manufacturing networks and decades of future planning make the consequences of withdrawal fundamentally different.
This is the central dilemma of large-scale military procurement. A programme can deliver valuable capabilities while simultaneously becoming so deeply embedded in military strategy that the government struggles to exercise normal purchasing discipline.
When Defense Jobs Become Congressional Power
Military contracts do not distribute their economic benefits only among corporate executives and shareholders. They support engineers, technicians, factory employees, software developers, maintenance specialists, construction workers and numerous smaller suppliers.
Those jobs are geographically dispersed across the United States, giving military expenditure a political significance that extends far beyond the Pentagon.
A weapons programme may involve major manufacturing facilities in one state, specialised components from another and maintenance or testing operations elsewhere. Local businesses benefit from employee spending, while communities receive tax revenue and investment connected to military production.
For members of Congress, these economic relationships complicate decisions about national defence.
A representative who believes the government spends too much on weapons may nevertheless oppose cancelling a programme that employs thousands of constituents. A senator who criticises Pentagon inefficiency may defend a military base or shipyard because its closure would seriously damage the regional economy.
Contractors understand the importance of these relationships.
The F-35 programme, for example, supports employment through a large network of suppliers operating across numerous states. The resulting economic footprint means that decisions affecting the programme can have political consequences in many congressional districts.
This can produce a powerful coalition in favour of continued funding.
The geographic distribution of defence manufacturing is sometimes described as pork-barrel politics, particularly when local economic benefits encourage legislators to protect programmes whose strategic necessity is disputed. However, not every geographically dispersed supply chain exists because companies deliberately spread contracts to influence politicians.
Military suppliers possess different technical specialisations, and many facilities were established long before current procurement decisions. Distributed production can also preserve industrial capabilities, provide access to specialised workers and reduce dependence on a single manufacturing location.
The employment benefits are real, as are the economic consequences of losing them.
The problem emerges when those benefits become inseparable from decisions about military necessity.
A programme may receive political support because it protects local employment even when the armed forces question its performance, cost or future relevance. Legislators who otherwise disagree on taxation, social policy or the size of government may support the same defence expenditures because their districts benefit from different parts of the military economy.
This does not mean every bipartisan defence vote is evidence of corporate manipulation. National-security priorities can command genuine support across political divisions.
But the geographic organisation of military production gives spending decisions a political resilience that technical performance alone may not justify. Cancelling a weapons programme can become a fight not simply about defence strategy, but about factories, livelihoods and the economic future of entire communities.
Campaign Money and the Politics of Military Spending
Defence contractors also participate in American politics through campaign contributions and lobbying, particularly among lawmakers who influence military budgets and procurement policy.
Members of the House and Senate Armed Services Committees occupy especially important positions. Their committees help shape defence legislation, oversee military institutions and determine which programmes receive congressional support through the annual defence authorisation process.
For companies competing for contracts worth billions of dollars, maintaining access to these lawmakers has obvious value.
A Public Citizen analysis of the 2022 election cycle examined contributions from defence-industry employees and political action committees to members of the Armed Services Committees. It reported approximately $10.2 million in contributions associated with committee members who voted to increase proposed military spending for fiscal year 2023.
The analysis found a substantial difference between lawmakers supporting the increases and those opposing them. Legislators who voted in favour received approximately $151,722 on average, compared with around $42,967 for those voting against the increases.
These figures reveal a meaningful relationship between political giving and support for larger defence budgets. They do not, by themselves, establish that contractors purchased particular votes.
A lawmaker representing a district with substantial military employment may already support higher defence spending because of economic or strategic priorities. Defence-related donors may then contribute to that politician precisely because their existing positions align, rather than causing those positions through donations.
Political influence is often more subtle than a direct financial exchange.
Campaign contributions can strengthen relationships with elected officials, while lobbying provides opportunities to present industry perspectives, discuss technical requirements and advocate particular programmes. Lawmakers and their staff may depend on specialised information supplied by contractors when evaluating complex military systems.
This gives organised industrial interests an advantage over taxpayers who do not possess comparable resources.
A contractor may have billions of dollars riding on whether a programme survives. Its executives, employees, investors and lobbying representatives therefore have strong incentives to follow every relevant budget decision and argue for their preferred outcome.
The cost of a programme, by contrast, is distributed across millions of taxpayers. Each individual may bear only a small share and have little reason to study its detailed procurement history.
Economists describe this as a problem of concentrated benefits and dispersed costs. Groups receiving large, identifiable benefits can organise more effectively than a broad population bearing relatively small individual burdens.
That imbalance exists in industries beyond defence, but military expenditure introduces additional complications. National-security decisions often involve classified information, specialised technology and arguments about threats that ordinary citizens cannot independently evaluate.
The result is a political environment in which organised industry interests can enjoy sustained access and influence without any need to demonstrate an explicit illegal arrangement.
The Revolving Door From the Pentagon to Industry
Campaign finance and lobbying allow companies to influence government from outside its institutions. The revolving door creates another relationship by moving people directly between public authority and private industry.
William J. Lynn III’s career provides an illustration.
After serving as under secretary of defense during the Clinton administration, Lynn joined Raytheon and became a senior executive and registered lobbyist. His experience made him valuable to the company because he understood defence acquisition, budgeting and the Pentagon’s internal operations.
When Obama appointed him deputy secretary of defense in 2009, the administration faced a conflict between its ethics commitments and its desire to recruit an experienced official.
Obama’s rules were not a universal prohibition on anyone with industry experience entering government for two years. They included restrictions on particular matters involving former employers or lobbying activities, recusal requirements and provisions allowing waivers when appointments were considered sufficiently important.
Lynn received such a waiver and served until 2011.
He subsequently returned to the defence industry, becoming chief executive of DRS Technologies, later known as Leonardo DRS, in 2012. He remained in a leading role for more than a decade before the company announced his retirement as chairman and CEO effective January 1, 2026.
His career demonstrates how the same expertise can produce opportunities on both sides of government service.
Lynn was not an isolated example. A Government Accountability Office investigation into post-government employment found that 14 major defence contractors employed 1,718 individuals in 2019 who had left senior or acquisition-related Department of Defense positions between 2014 and 2019.
The investigation also identified more than 37,000 former Defense Department personnel from that departure cohort working for those companies overall.
These figures measure particular employment relationships and periods, not a finding that everyone involved acted improperly. Nevertheless, they demonstrate the substantial movement of personnel between the military establishment and its major suppliers.
The pattern extends to some of the country’s highest-ranking military officers.
A Quincy Institute study of retired four-star generals and admirals found that 26 of the 32 officers retiring between June 2018 and July 2023 subsequently held positions connected to the arms industry. Their activities included work as executives, board members, advisers, consultants, lobbyists and financiers.
Retired military leaders possess knowledge that private companies value enormously. They understand how the armed forces evaluate threats, which capabilities military commanders consider important and how major decisions move through defence institutions.
Former acquisition officials offer similar advantages in navigating procurement regulations, budgets and administrative processes.
Some senior officials also enter private equity, venture capital and advisory businesses that finance defence-related technologies. Former CIA director and military commander David Petraeus, for example, joined the investment firm KKR, while former secretary of defence Lloyd Austin previously held roles connected to Raytheon and Pine Island Capital Partners before entering the Biden administration.
These examples illustrate different forms of movement between public institutions, industry and finance. They should not be treated as proof that either individual improperly influenced a specific contract.
There are legitimate reasons for such transitions.
Former officers can help manufacturers understand battlefield requirements, improve equipment and identify problems in military operations. Experienced industry executives entering government may understand specialised technologies better than officials who have never worked directly with them.
Government agencies also face practical limits when recruiting and retaining people with technical expertise. Private companies can often offer compensation significantly above public-sector salaries.
The concern is therefore not that expertise crosses institutional boundaries. It is that career incentives can become entangled with public responsibilities.
An official who expects to seek employment with defence contractors may have reason to avoid antagonising potential future employers. A retired general may have professional relationships that influence how policymakers assess industry proposals, even without engaging in formally registered lobbying.
Such incentives can exist without an explicit promise of employment or a demonstrably corrupt decision.
This is why the revolving door presents an institutional problem rather than merely a question of individual character. Government requires expertise from people who understand its most complicated systems, but the commercial value of that expertise creates potential conflicts that conventional ethics rules cannot completely eliminate.
Does the Military-Industrial Complex Make War More Likely?
The most consequential criticism of the military-industrial complex is that companies benefiting from military expenditure may encourage policies that make war more likely.
There is a logical basis for concern. Businesses producing weapons, aircraft, missiles and military electronics benefit from governments maintaining substantial defence budgets. Some forms of conflict increase demand for ammunition, replacement equipment and newly developed military capabilities.
However, an economic incentive to support military expenditure is not sufficient evidence that contractors cause wars.
Countries enter conflicts for numerous reasons, including security threats, alliance commitments, ideological disputes, territorial ambitions, domestic political pressures, intelligence failures and decisions by foreign governments. American military interventions also reflect choices made by presidents, Congress, military commanders and other institutions.
Defence companies do not exercise complete control over these forces.
Their influence is better understood through the policy environment in which decisions are made.
When a government possesses extensive military capabilities, established procurement systems and powerful institutions organised around potential conflicts, military solutions may become easier to propose and implement. Government officials already have equipment, operational plans, contractors and personnel capable of supporting those choices.
Diplomatic alternatives may face different institutional constraints.
Contractors also have incentives to promote the strategic importance of capabilities they manufacture. Missile-defence companies benefit from government attention to missile threats, shipbuilders have interests in naval modernisation, and cybersecurity firms gain when digital conflict receives greater national-security priority.
Those threats may be entirely genuine.
The problem arises when organisations with substantial financial interests possess disproportionate resources to shape how threats are discussed and which responses receive serious consideration.
Military spending can also develop political momentum independent of any immediate conflict. A large weapons programme may continue because existing military plans depend on it, factories employ thousands of people and abandoning it would create financial and political costs.
Under these circumstances, political leaders may find it easier to preserve or expand military programmes than to question their necessity.
This influence is not the same as proving that contractors deliberately manufacture threats or force governments into wars. The relevant concern is whether their financial and institutional power gives military solutions stronger organised support than diplomacy, restraint or alternative public investments receive.
There is also a distinction between military preparedness and militarism.
Effective armed forces can deter aggression, protect allies and reduce the likelihood of conflict by making attacks prohibitively costly. A defence industry capable of producing essential equipment can therefore serve genuine security purposes.
The difficulty is determining when expenditure supports those purposes and when it increasingly serves the institutions benefiting from continued spending.
The military-industrial complex does not need to control every foreign-policy decision to exert meaningful influence. It can shape which capabilities are available, which threats are prioritised and how difficult it becomes for political leaders to consider alternatives.
That is a more defensible and more troubling account of its relationship with war than the claim that weapons manufacturers alone determine American foreign policy.
Can the United States Reclaim Control of Defense Spending?
The United States cannot solve the problems of the military-industrial complex simply by abolishing private defence companies or eliminating large portions of military spending.
Modern military preparedness requires specialised technologies, industrial facilities, skilled employees, research institutions and supply chains that must exist before a national emergency begins. Ships, advanced aircraft, missiles and sophisticated communications systems cannot be manufactured instantly when a conflict starts.
Maintaining these capabilities involves genuine costs.
The challenge is that preserving an industrial base does not automatically require preserving every existing contract, programme or corporate structure. A government can recognise the importance of military readiness while demanding stronger evidence that spending produces useful capabilities.
The scale of the issue is substantial. According to the Stockholm International Peace Research Institute’s assessment of military expenditure in 2025, the United States spent approximately $954 billion on its military, accounting for roughly one-third of global military expenditure.
SIPRI’s measure includes categories of military expenditure that should not be confused with a single Pentagon appropriation. Nevertheless, it illustrates the enormous resources involved in American defence policy.
Those resources support military personnel, operations, weapons development, global commitments, deterrence and industrial capacity. They also make the defence economy one of the largest and most politically consequential relationships between government and private industry.
Meaningful reform begins with restoring competition wherever possible.
The Pentagon can scrutinise mergers more carefully, particularly when proposed transactions would eliminate the remaining supplier of an essential component or reduce the number of companies capable of competing for future programmes. Preventing further concentration may preserve options that would otherwise disappear permanently.
Competition also depends on technical access.
When contractors maintain exclusive control over important designs, software interfaces or maintenance information, the government may be unable to obtain competitive bids for upgrades and support. Negotiating stronger technical-data rights and encouraging open system architectures could allow more companies to compete for parts of established programmes.
This would not eliminate the need for original manufacturers, but it could reduce dependence on them for every future improvement.
The Pentagon also needs sufficient technical expertise within government.
When procurement agencies lack experienced engineers, cost analysts, programme managers and software specialists, they become dependent on contractors to explain whether proposed expenses and performance claims are reasonable. Rebuilding internal capacity would give officials greater ability to challenge estimates, identify problems and evaluate alternative designs.
Procurement contracts themselves require more effective incentives.
No single contracting model works for every military programme. Fixed-price arrangements can create useful discipline when requirements and costs are predictable, while research involving considerable technological uncertainty may justify cost reimbursement.
The important question is how risks are allocated and whether payments, performance targets and oversight procedures encourage contractors to deliver the capabilities the government needs.
The F-35’s readiness problems demonstrate why expenditure alone cannot serve as the measure of successful procurement. Oversight must examine whether aircraft are available for missions, whether maintenance systems function effectively and whether contractor compensation is connected to results the military can actually use.
Political reform presents a different challenge.
Members of Congress need to evaluate military programmes according to strategic necessity, affordability and performance, even when those programmes support employment in their districts. This does not require ignoring workers or communities affected by cancellation. It requires separating industrial and regional economic concerns from claims that a particular weapons system is essential to national defence.
More transparent budgeting, independent audits and realistic cost estimates could help expose problems before they become too expensive and politically difficult to reverse.
The revolving door also warrants stronger safeguards.
Cooling-off periods, conflict-of-interest disclosures and recusal requirements can limit the most immediate opportunities for private employment to interfere with public decision-making. Ethics waivers should be transparent and sufficiently exceptional to preserve the credibility of the restrictions they suspend.
Rules governing lobbying and influence may also need to account for advisory, consulting and financial relationships that do not always fit conventional definitions of registered lobbying.
Such measures cannot prevent every conflict of interest, nor should they prohibit government from recruiting qualified people with relevant industry experience. Their purpose is to ensure that expertise serves public decisions without allowing prospective private rewards to determine those decisions.
Newer defence-technology firms offer another possible source of competition. Businesses developing software, autonomous systems, drones and advanced electronics may challenge established suppliers in certain markets, particularly where development cycles can be shorter than those of traditional aircraft or shipbuilding programmes.
However, the emergence of new contractors does not automatically solve the underlying problem. If government procurement creates the same long-term dependencies, restrictions on technical access and concentrated political interests, a new generation of businesses can eventually become entrenched as well.
Reform therefore requires more than replacing established companies with different suppliers.
It requires the government to maintain the ability to evaluate performance independently, encourage meaningful competition, challenge unnecessary expenditure and terminate programmes when their costs can no longer be justified.
These safeguards will not eliminate institutional self-interest. Military leaders will continue seeking capabilities, businesses will pursue contracts, politicians will defend constituents and former officials will look for employment.
The objective is to ensure that none of these interests becomes so powerful that government loses the practical ability to question them.
Eisenhower understood that modern national security required cooperation between government, the armed forces, scientists and private industry. His warning was directed at what could happen if that necessary partnership escaped effective democratic control.
More than six decades later, the military-industrial complex remains powerful because its influence is embedded in ordinary institutional relationships. It provides technologies the armed forces depend on, employment communities value, revenue investors seek and expertise government agencies struggle to replace.
That does not make every contractor corrupt or every military programme unnecessary. It means decisions about national defence cannot be judged solely by the priorities of the institutions benefiting from them.
The greatest danger is not that the United States possesses an enormous defence industry. It is that the economic, political and professional relationships surrounding that industry may gradually make its continued expansion appear inevitable, even when particular programmes or policies no longer serve the public interest.
A democracy must be capable of maintaining military strength without surrendering the authority to question how that strength is acquired, funded and used. That was the essential challenge behind Eisenhower’s warning, and it remains the central question confronting the American military-industrial complex.
