The Next Defense Industrial Base Will Extend Beyond Traditional Defense Companies

The defense industrial base is not disappearing.

It is expanding.

For decades, the United States has relied on an established network of prime contractors, manufacturers, specialized suppliers, laboratories, and government organizations to develop and sustain military capability. That system remains essential.

Major weapons platforms, munitions, aircraft, vehicles, ships, communications systems, and the infrastructure supporting them cannot be replaced by a collection of startups or commercial technology companies.

But the environment surrounding that system has changed.

Some of the technologies increasingly relevant to national security are now advancing primarily or simultaneously in commercial markets. Artificial intelligence, autonomous systems, advanced manufacturing, energy storage, cybersecurity, communications, robotics, microelectronics, logistics technologies, and other capabilities are being developed across an economy much larger than the traditional defense sector.

The strategic question is therefore no longer whether commercial industry will contribute to future defense capability.

It already does.

The more important question is whether the United States can consistently identify those capabilities, connect them to legitimate military requirements, integrate them into existing systems, create acquisition pathways, scale production, and sustain them under operational conditions.

That requires thinking about the defense industrial base differently.

The Traditional Defense Industrial Base Remains Essential

A broader industrial ecosystem should not be confused with an argument against traditional defense companies.

The opposite is true.

Large defense primes perform functions that are difficult to reproduce elsewhere. They integrate extraordinarily complex systems, manage large supplier networks, operate under demanding security and regulatory environments, maintain specialized engineering workforces, and execute programs that may span decades.

The Department's own industrial strategy recognizes the need to strengthen this base rather than replace it. The first National Defense Industrial Strategy, released in 2024, organized that effort around four priorities: resilient supply chains, workforce readiness, flexible acquisition, and economic deterrence. The strategy describes the objective as building a more modern and resilient defense industrial ecosystem capable of meeting national-security requirements.

The scale of that ecosystem is already significant. GAO reported in 2025 that the

Department estimates more than 200,000 suppliers contribute to weapon systems and noncombat goods, including items such as batteries and manufacturing equipment.

That number illustrates an important reality.

The defense industrial base has never been only the major primes.

What is changing is the range of industries that may need to participate in it.

Defense-Relevant Innovation Is Increasingly Commercial

The convergence between commercial and military technology has been developing for years, but the institutional response is becoming more explicit.

The Defense Innovation Unit was created specifically to accelerate the adoption of commercially derived technology. In January 2026, the Department reorganized portions of its innovation ecosystem while retaining DIU's role in technology scouting, rapid contracting, and commercial adoption. The new structure explicitly seeks to connect operational problems with commercial solutions.

That distinction matters.

Commercial companies may now develop technology relevant to military operations without having started as defense contractors.

A company working on energy systems for transportation may create technology relevant to tactical power.

A robotics company serving warehouses may develop autonomy applicable to military logistics.

A cybersecurity company protecting enterprise networks may possess identity technology relevant to distributed military systems.

A manufacturer improving additive production may develop processes relevant to contested sustainment.

A communications company solving commercial connectivity problems may possess technology relevant to resilient command and control.

The commercial market does not need to be developing a "defense product" for the underlying capability to have defense relevance.

But that creates another problem.

Technology relevance is not the same as defense readiness.

Commercial Companies Were Not Built Around Defense Acquisition

Many companies outside the traditional defense ecosystem were designed around completely different assumptions.

Their customers may buy products in weeks rather than years.

Their product development cycles may be measured in months.

Their investors may expect rapid commercial growth.

Their intellectual-property strategies may depend on retaining control of technology.

Their cybersecurity infrastructure may have been built for commercial data rather than protected government information.

Their manufacturing capacity may be optimized around a commercial customer base.

Their sales teams may understand markets but not military requirements.

When those companies encounter the defense acquisition environment, the gap can become substantial.

GAO has studied this problem repeatedly. Its work on nontraditional companies identified challenges associated with entering the defense market, and more recent analysis continues to show that acquisition pathways and contracting mechanisms

influence how effectively commercial technology can transition into government use.

This creates two separate readiness questions:

Is the technology ready?

and

Is the company ready?

Those questions are not interchangeable.

A technically mature product can still be supported by an organization that lacks the compliance infrastructure, production capacity, contracting knowledge, capital, or execution systems necessary to perform at government scale.

The future industrial base must account for both.

LSCO Expands the Scale of the Problem

This becomes particularly important as the Army prepares for large-scale combat operations.

LSCO introduces requirements that extend well beyond individual platforms.

Distributed operations increase pressure on logistics.

Electronic systems increase demand for power.

Autonomy changes the relationship between people, machines, communications, and data.

Contested supply lines increase the importance of repair, production, and sustainment closer to the point of need.

Modern sensing and communications increase reliance on networks and microelectronics.

Operational attrition increases the importance of industrial depth and replacement capacity.

The Army's FY2026 budget materials explicitly connect readiness investments to the capacity required to support strategic surge for LSCO in a multidomain environment.

Army transformation efforts also continue to emphasize experimentation, modernization, speed, and direct soldier involvement in shaping future capabilities.

That changes the industrial question.

The requirement is no longer simply:

Can we build the best system?

It increasingly becomes:

Can we produce, integrate, replace, repair, supply, adapt, and sustain capability at the scale a prolonged conflict could require?

That is an industrial ecosystem problem.

The Future DIB Will Cross Industries

A future defense industrial ecosystem prepared for that environment will likely draw more heavily from sectors that have historically sat adjacent to defense rather than inside it.

Energy companies matter because operational capability increasingly depends on power.

Advanced manufacturers matter because production flexibility affects replacement capacity and supply-chain resilience.

Commercial AI companies matter because software and data increasingly influence decision advantage.

Cybersecurity companies matter because every connected capability expands the digital attack surface.

Telecommunications and networking companies matter because distributed forces depend on resilient connectivity.

Logistics companies matter because contested operations require different approaches to distribution, visibility, transportation, and sustainment.

Commercial robotics and autonomy companies matter because unmanned capability is expanding across air, land, maritime, and logistics applications.

Microelectronics companies matter because sophisticated systems depend on components produced through globally interconnected supply chains.

GAO's 2025 assessment of defense industrial-base risks illustrates the importance of that broader industrial perspective. It found that foreign dependency contributes to vulnerabilities across defense supply chains and highlighted significant overseas concentration in areas such as microelectronics production and assembly.

A defense industrial strategy therefore cannot focus only on final weapons systems.

It must also consider the commercial technologies, industrial capacity, components, materials, infrastructure, and capital behind them.

Discovery Alone Is Not Enough

Opening the defense market to more commercial companies does not solve the problem by itself.

More industry days will not solve it.

More technology demonstrations will not solve it.

More innovation organizations will not solve it unless promising capability can transition

into operational use.

The pathway still requires:

Mission Problem

↓

Requirement Validation

↓

Commercial Capability Discovery

↓

Technical Assessment

↓

Integration

↓

Operational Validation

↓

Acquisition and Contracting

↓

Production

↓

Fielding

↓

Sustainment

Every step introduces a different form of friction.

The Department has increasingly acknowledged this transition challenge. Its 2024 innovation update emphasized reducing roadblocks and using innovative contracting approaches to improve work with commercial and nontraditional companies. More recent acquisition reform initiatives continue to focus on reducing the time between identifying a requirement and getting capability under contract and into the field.

The challenge is therefore no longer simply finding innovation.

It is building a system capable of absorbing innovation.

Integration Will Become an Industrial Capability of Its Own

This is where the future ecosystem becomes more complex.

Commercial technology rarely arrives perfectly configured for a military requirement.

It may need to connect to another technology.

It may need to integrate with a legacy platform.

It may require a different power architecture.

It may require cybersecurity hardening.

It may require ruggedization.

It may require new interfaces.

It may need to operate inside an existing logistics or command-and-control environment.

The solution may ultimately involve multiple commercial companies, an established defense prime, government technical organizations, manufacturers, and specialized integrators.

That means integration itself becomes strategically important.

The winners will not necessarily be the organizations with access to the largest number of products.

They will be the organizations capable of determining which technologies belong together against a specific mission problem and how to turn that combination into an executable capability.

That is fundamentally different from technology scouting.

Capital Is Part of Industrial Readiness

There is another component that defense discussions have historically treated separately from acquisition: capital.

That separation is becoming harder to maintain.

A commercially successful technology company may need substantial investment to build a new manufacturing line, expand facilities, secure domestic suppliers, hire specialized personnel, harden cybersecurity infrastructure, acquire equipment, or increase working capital before it can satisfy meaningful government demand.

The creation and expansion of the Office of Strategic Capital reflects growing recognition of this relationship. OSC's investment strategy explicitly seeks to attract private capital toward national-security priorities and critical technology supply chains.

The FY2026 defense budget proposal included significant funding for the office's loan program, and OSC began executing direct industrial-base financing in 2025.

That represents an important shift in thinking.

Capital is not separate from defense readiness when insufficient capital prevents strategically relevant companies from scaling.

But capital alone is not the solution.

Investing in an organization that lacks operational discipline, production readiness, customer clarity, or an executable government pathway simply finances existing weaknesses.

Capital accelerates prepared organizations.

Industrial strategy therefore requires alignment between technology, organizational readiness, demand, acquisition, and capital.

A Broader Ecosystem Does Not Mean Lower Standards

Expanding the defense industrial ecosystem should not mean lowering the requirements necessary to protect national security.

Commercial companies entering the market still need to operate within appropriate cybersecurity, security, contracting, quality, supply-chain, and performance requirements.

The objective should be to make those pathways understandable and executable, not eliminate the standards that protect government information and operational capability.

This is where readiness becomes important.

Companies should understand what operating in the defense market actually requires before opportunity arrives, not after winning work they are unprepared to perform.

Government benefits when more capable companies can compete.

Industry benefits when expectations are clearer.

And the industrial base becomes stronger when participation expands without sacrificing accountability.

The Industrial Base Should Be Viewed as an Ecosystem

The traditional image of the defense industrial base is often hierarchical:

Government requirement.

Prime contractor.

Subcontractors.

Suppliers.

That structure will continue to exist.

But the emerging environment increasingly looks like a network:

Government

Traditional Primes

Commercial Technology Companies

Manufacturers

Research Institutions

Small Businesses

Capital Providers

Integrators

Supply-Chain Partners

Operational Users

Different problems will require different combinations of that ecosystem.

No single model will fit every requirement.

Some capabilities should continue through established programs.

Some should be purchased directly as commercial products.

Some will require traditional prime integration.

Some will emerge through rapid acquisition pathways.

Some will require new combinations of commercial technologies.

The objective should not be forcing every capability through the same pathway.

The objective should be creating enough flexibility to use the right pathway for the problem.

Building the Next Defense Industrial Base

The next defense industrial base will not be defined solely by which companies already have government contracts.

It will increasingly be defined by the nation's ability to identify useful capability wherever it is being developed and connect that capability to national-security demand.

That means developing stronger pathways between:

Mission requirements and commercial markets.

Technology and integration.

Innovation and acquisition.

Production demand and capital.

Fielding and sustainment.

Traditional defense companies will remain essential.

But they will not represent the entire industrial capacity available to the United States.

The country possesses an enormous commercial innovation base, deep capital markets, advanced manufacturing capability, world-class research institutions, and thousands of companies developing technologies with potential national-security relevance.

The strategic advantage will come from connecting those resources before a crisis requires them.

The next defense industrial base will therefore be more than a collection of defense contractors.

It will be an industrial ecosystem capable of turning American innovation, capital, manufacturing, and technology into operational capability at the speed and scale national security demands.
