The Image Tube Shortage

Section 1 — Topic

A Duopoly That Is No Longer Adequate

The concentration of U.S. Generation 3 image intensifier tube production in two companies is not an accident of market forces. It is the product of decades of procurement decisions that awarded large, long-duration contracts to a small number of established suppliers, created entry barriers through proprietary housing architectures and qualification requirements that favored incumbents, and never cultivated the domestic industrial base depth needed to sustain the demand now placed on it.

The result is a supply chain with no meaningful redundancy. L3Harris Technologies, through its Integrated Vision Solutions division, and Elbit Systems of America, through its Roanoke, Virginia facility, are the only domestic manufacturers of Gen 3 image intensifier tubes in production at scale. The Defense Logistics Agency recognized this concentration explicitly when it awarded $135 million contracts to each company in February 2025 for MX-11769 tubes supporting the AN/PVS-14 program, structured as IDIQ contracts running through January 2030. Two vendors. One program. A five-year procurement horizon with no diversification mechanism.

The March 2026 Army BiNOD contract introduced Photonis Defense as a third participant, awarding $352.6 million of a $1.27 billion program alongside L3Harris and Elbit. This is worth examining carefully and is addressed in the position section of this paper. The immediate supply picture, however, remains unchanged. The present supply chain is L3Harris and Elbit. And both are under significant pressure.

L3Harris: Twelve-Month Lead Times and Constrained Commercial Access

L3Harris Technologies is the larger of the two domestic tube manufacturers and holds the deeper track record of supplying Generation 3 tubes to the U.S. military. Its production facilities prioritize large government programs of record, which occupy the majority of available capacity. Commercial and law enforcement orders receive allocation from whatever production capacity remains after military contract fulfillment.

Current industry-reported lead times for new L3Harris tube orders run approximately 12 months. For law enforcement agencies, federal entities outside of DoD procurement channels, and distributors attempting to maintain inventory, this represents a planning and operational challenge that the current supply structure does not address. Pricing has escalated in parallel with lead times, reflecting the company's position as one of only two domestic suppliers with no competitive pressure to moderate costs for buyers outside the major IDIQ vehicles.

Elbit Systems of America: Twenty-Four Month Lead Times

Elbit Systems of America's night vision division holds the ENVG-B program of record alongside L3Harris, the AN/PVS-31D SBNVG contract for the Marine Corps, and a co-award of the DLA's MX-11769 tube supply contract. Industry-reported lead times for new Elbit tube deliveries currently run approximately 24 months. This timeline is operationally incompatible with procurement requirements for agencies operating outside the major programs of record and any requirement that cannot sustain a two-year wait for fulfillment.

It should be noted that persistent industry discussion and distributor-level observation suggests additional quality and yield challenges in Elbit's recent production runs. This paper treats those observations as unverified market intelligence rather than documented fact. However, the lead time data alone, corroborated by contract delivery patterns reported across DoD weapon system assessments, is sufficient to characterize the supply constraint as structural rather than incidental. If the quality observations circulating in the industry prove accurate upon further investigation, they would compound the delivery timeline problem significantly.

Both L3Harris and Elbit have a documented history of late government contract delivery. The GAO's June 2023 annual assessment of DoD weapon system acquisition identified supplier disruptions and quality control deficiencies as primary drivers of schedule delays across the assessed portfolio. The night vision programs are consistent with the broader pattern the GAO has documented.

The Commercial and Law Enforcement Market Is Being Underserved

The consequences of concentrated tube supply extend beyond large military programs. Municipal and state law enforcement tactical units, federal agencies operating outside DoD procurement channels, and qualified domestic operators all depend on the same two manufacturers. That market is receiving residual allocation after military contract fulfillment. With lead times of 12 to 24 months, law enforcement agencies cannot plan equipment procurement around reliable delivery schedules. Distributors cannot maintain practical inventory levels. Equipment gaps persist for months at a time in agencies that have operational night vision requirements.

This is not a peripheral concern. Law enforcement agencies conducting joint operations with military units require compatible Generation 3 equipment. Federal entities that cannot access DLA supply channels directly have no alternative procurement pathway. The tube shortage is a national capability problem that extends well beyond the military procurement system, and its structural cause is the same concentration of supply that affects DoD programs.

The situation in plain terms: L3Harris is running 12-month lead times. Elbit is running 24-month lead times. Both have documented patterns of late government contract delivery. The commercial and law enforcement markets have been deprioritized. The government is procuring night vision capability that depends entirely on two suppliers, and neither is meeting total demand.

Section 2 — Position

Why the Proposed Alternatives Are Not Near-Term Solutions

When the two-vendor concentration problem is raised, three alternatives are typically cited: NNVT, Photonis, and domestic production incentives. Each requires honest evaluation before a credible policy response can be proposed.

NNVT: Ineligible and Unproven for Government Use

NNVT, or North Night Vision Technology, is a Chinese state-affiliated manufacturer that produces image intensifier tubes sold commercially in Western markets under various brand names. NNVT tubes appear in discussions of supply chain alternatives because of their availability and competitive pricing relative to domestic alternatives.

There are two fundamental problems with NNVT as a government procurement solution. The first is legal: NNVT tubes are categorically ineligible for U.S. government procurement under the Buy American Act, the Trade Agreements Act, and relevant DFARS provisions. China is not a qualifying country under these statutes. No waiver, designation change, or rebranding exercise changes that eligibility status. The procurement pathway does not exist under current law, and the national security rationale for keeping it closed is well-documented in DoD foreign dependency policy.

The second problem is technical: NNVT does not produce Generation 3 image intensifier tubes. NNVT tubes are Generation 2+ products. The gallium arsenide photocathode technology that defines Gen 3 performance is not present in NNVT's production. Their tubes have not been tested or validated against U.S. military specification for Generation 3 applications. For ground force night vision requirements that depend on Gen 3 GaAs photocathode performance, NNVT is not a substitute in any technical sense. It is a different class of product, with different performance characteristics, different operating limitations, and no qualification data supporting military use.

Photonis: A Gen 2+ Manufacturer, Not a Near-Term Gen 3 Solution

Photonis, operating under its parent company Exosens, is frequently cited as a potential third domestic source for image intensifier tubes. The company announced in March 2025 a 20 million euro investment to build a new tube production facility in Sturbridge, Massachusetts, and was awarded a $352.6 million share of the Army's BiNOD contract in early 2026. These developments are meaningful for the medium-term supply picture and represent the most significant industrial base development in the night vision tube market in years.

However, the characterization of Photonis as a Gen 3 alternative requires clarification. Photonis markets its image intensifier tubes under generation branding such as '4G' and '5G,' which is commercial nomenclature with no formal U.S. military generation designation. The U.S. military recognizes three generations of image intensification technology. The defining characteristic of Generation 3 is the gallium arsenide photocathode. Photonis tubes use a different photocathode architecture, placing them technically in the Generation 2+ category by the standards the U.S. military and the broader technical community apply. The marketing language Photonis uses has caused genuine confusion in the market, but the technical classification is not ambiguous.

For procurement officers and program managers evaluating tube supply alternatives: the Photonis U.S. facility announced in March 2025 is under construction and will not begin manufacturing until early 2027 by the company's own projection. The tubes that facility will produce are Gen 2+ products. For programs that specify Generation 3 GaAs photocathode technology, Photonis does not represent a compatible near-term alternative regardless of facility timeline. The BiNOD contract award reflects a broader evaluation of the system as a whole and does not change the tube classification.

The Qualification Framework Has Not Kept Pace

The third dimension of this problem is less visible than lead times or manufacturer classifications, but it may be the most consequential for the long-term health of the domestic tube supply chain. The qualification criteria that govern which manufacturers and which tubes can supply the U.S. military have not been substantively updated in decades.

The foundational performance parameter standard governing image intensifier tube evaluation, MIL-STD-1858, was established in 1981 and has not seen meaningful revision since. The Omnibus contract framework, which has served as the primary procurement vehicle for Gen 3 tubes since approximately 1982, has evolved through nine iterations, but those iterations have not consistently raised the technical bar. Omni VIII, the most recent widely implemented contract iteration prior to the emerging Omni IX standard, actually reduced minimum performance thresholds compared to Omni VII, removing performance objectives and retaining only threshold minimums. The result was a specification that admitted more tubes into the qualified pool at lower performance levels, which increased supply volume while reducing the performance floor.

The qualification pathway for a new domestic tube manufacturer is built on a framework that is fundamentally 40-plus years old. The test methodologies, performance parameters, and acceptance criteria were developed for a generation of manufacturing technology and operational environment that no longer reflect the current state of the art. A manufacturer using modern production processes, advanced photocathode deposition techniques, or novel microchannel plate geometries faces a qualification process designed around the assumptions of 1980s manufacturing. This is not a pathway optimized to attract new entrants. It is a pathway optimized to protect incumbents.

The market consequence is precisely what has occurred: two manufacturers have dominated domestic Gen 3 tube production for decades, and no credible new domestic competitor has entered the qualified supplier base in the intervening period. The qualification framework is not the only barrier to new entry, but it is a structural one, and it has never been seriously addressed.

The alternatives most often cited as solutions to the two-vendor problem are not solutions. NNVT is legally ineligible and technically misclassified as a Gen 3 alternative. Photonis produces Gen 2+ tubes under commercial generation branding and will not have a U.S. production facility operational until 2027 at the earliest. The qualification framework that would govern any new entrant is built on standards that are over 40 years old and were most recently revised in a direction that reduced performance requirements. The problem is structural. The remedies must be structural.

Section 3 — Counter-Argument

Engaging the Defense of the Status Quo

Objection 1: L3Harris and Elbit Are Proven, Trusted Suppliers

The strongest argument for the current two-vendor structure is institutional depth. L3Harris and Elbit have supplied Gen 3 tubes to the U.S. military for decades. Their tubes have been qualified, fielded, and proven in combat across multiple theaters and generations of platforms. The qualification data is extensive. The failure modes are understood. Program offices have decades of contracting history with both companies.

This track record is real and it matters. It does not, however, answer the current problem. Historical performance does not overcome a 24-month delivery lead time. Institutional trust does not reduce the pricing leverage that a two-vendor monopoly extracts over time. A supplier can be both trusted and inadequate to meet current demand, and the evidence presented in Section 1 of this paper indicates that is precisely the situation. The argument for retaining the two-vendor structure is an argument for stability. The cost of that stability is a supply chain that routinely cannot meet demand, with no alternative when either supplier encounters difficulty.

Objection 2: Developing New Qualified Suppliers Takes Too Long to Address the Current Shortage

A practical objection holds that even if the qualification framework were reformed and new manufacturers were incentivized to enter the market, the timeline to produce qualified domestic Gen 3 tubes from a new entrant is measured in years, not months. The current shortage requires solutions on a shorter timeline than industrial base development allows.

This objection is accurate about the timeline and wrong about the conclusion. The correct response to a long development timeline is to start immediately rather than to defer indefinitely. The shortage being experienced today is the consequence of not investing in supply chain diversification five or ten years ago. Accepting that logic and using it to justify continued inaction is the mechanism by which a structural vulnerability becomes permanent.

Furthermore, addressing the qualification framework does not require waiting for new manufacturers to emerge. Reforming the criteria, modernizing the test methodologies, and establishing transparent qualification pathways creates the conditions under which new entrants can make investment decisions. It signals to high-technology sensor manufacturers and advanced materials companies that the government is serious about supply diversification. That signal has commercial value independent of any specific manufacturer's timeline.

Objection 3: The Current Backlog Will Resolve as Contract Volume Drives Production Investment

Some contracting personnel characterize the current lead time situation as a temporary capacity constraint rather than a structural problem, arguing that the new IDIQ contracts will drive production investment from both L3Harris and Elbit, and that the backlog will naturally resolve as capacity catches up with demand.

This interpretation is not supported by the direction of travel over the past several years. Lead times at Elbit have not shortened as contract volume has increased. L3Harris pricing has not declined as demand has grown. The backlog argument would predict the opposite of both trends. The structural concentration of Gen 3 tube supply is the more accurate description of the problem, and structural problems require structural responses. Waiting for the backlog to clear is not a supply chain policy. It is an absence of one, and it is producing measurable operational consequences today.

Section 4 — Solution

Three Policy Remedies for a Structural Problem

The image tube shortage requires remedies that match the structural nature of the problem. Incremental adjustments to existing procurement vehicles will not close a supply gap created by decades of market concentration and regulatory inertia. The following three responses address the problem at the level it actually exists.

Response 1: Invest in and Incentivize Domestic High-Technology Sensor Manufacturers to Enter the IIT Supply Chain

The most direct way to reduce the risk of a two-vendor Gen 3 tube supply chain is to develop a third and fourth domestic vendor. This is not a straightforward commercial proposition. The capital requirements for a Gen 3 gallium arsenide photocathode production facility are substantial. The qualification process is lengthy. The customer base is concentrated in a government procurement system that has historically awarded large, exclusive contracts to incumbents, providing limited commercial incentive for new entrants to make the investment required to compete.

The government must change that calculus. This means directing investment through mechanisms such as the Defense Production Act, DARPA programs, or Section 804 Other Transaction Authority toward companies with advanced sensor manufacturing capabilities and the technical foundation to develop Gen 3 tube production. It means providing direct qualification support, including government-funded testing resources and technical assistance, to reduce the financial barrier of the qualification process for new entrants. It means structuring future tube procurement contracts in ways that reserve capacity for emerging domestic suppliers and provide the revenue visibility that justifies capital investment.

The United States has world-class high-technology sensor manufacturing capability distributed across its semiconductor, photonics, and advanced materials industrial base. The barriers preventing that capability from entering the IIT supply chain are not primarily technical. They are regulatory, financial, and structural. Targeted government action to lower those barriers is the most consequential investment the DoD can make in the long-term resilience of its night vision capability.

Response 2: Make Tube-Agnostic Housing Architecture the Procurement Standard

As argued in detail in Paper 2 of this series, the procurement of tube-agnostic NVG housings is the prerequisite that makes supply chain diversification operationally meaningful. This point bears repeating in the context of the tube shortage because the connection is direct: if every government-procured housing accepts only one manufacturer's tubes, then a new qualified tube manufacturer has no government market to enter. The housing architecture is the gate through which tube supply competition must pass.

Requiring tube-agnostic housing architecture across future NVG housing procurements creates the market infrastructure that new tube suppliers need in order to justify the investment in qualification. A new domestic Gen 3 tube manufacturer that can sell into millions of dollars of existing government housing inventory has a viable business case. A new manufacturer whose tubes are compatible only with a niche commercial housing that the government does not procure does not. The housing specification change and the supply chain diversification effort are not independent policy decisions. They are two components of the same solution.

This requirement is available to implement today, on the next housing procurement cycle, without waiting for new tube manufacturers to reach qualification. It establishes the foundation. The diversification follows.

Response 3: Develop and Implement Updated Qualification Criteria for Image Tube Suppliers

The qualification framework governing domestic Gen 3 tube suppliers has not been substantively modernized in over 40 years. MIL-STD-1858, the foundational performance parameter standard for image intensifier tube evaluation, dates to 1981. The Omnibus procurement framework has been in continuous operation since approximately 1982. In its most recent widely implemented form, Omni VIII, the framework reduced minimum performance thresholds rather than advancing them, admitting more tubes at lower performance levels to increase supply volume.

A qualification framework that is 40 years old and trending toward lower standards is not a framework designed to attract the next generation of advanced sensor manufacturers. It is a framework designed to sustain incumbents. Modernizing it is not a minor administrative update. It is a fundamental policy decision about what the government expects from its tube supply base and what kind of manufacturer it wants to attract.

Updated qualification criteria should reflect current understanding of photocathode science, microchannel plate technology, and the operational performance envelope that modern ground force operations actually require. They should establish transparent, accessible qualification pathways that allow new entrants to understand the requirements, plan their development, and invest with confidence in government procurement as the commercial endpoint. They should be structured to welcome technical innovation rather than to privilege the manufacturing processes of companies that were qualified under criteria written when Ronald Reagan was in his first term.

The GAO has repeatedly documented the cost of DoD programs failing to update technical standards and qualification processes in pace with technological change. The image intensifier tube market is a direct example of that failure, and the supply chain consequences are now visible and operational. The time to modernize the qualification framework is not when the shortage is already being felt. That time passed years ago. The appropriate response now is to begin the process without further delay.
