1. Executive Summary

The United States Department of Defense (DoD) is undertaking a structural pivot in its force posture, moving toward the integration of autonomous and uncrewed systems (UxS) at a transformative scale. Fiscal planning reflects this transition, with extensive capital allocated toward reshaping the battlefield. Recent budget requests demonstrate a prioritization of drone warfare and counter-drone technologies, projecting tens of billions of dollars toward autonomy, platform acquisition, contested logistics, and munitions over the coming fiscal years.¹ Central to this transition is the Replicator initiative, a framework designed to overcome traditional bureaucratic inertia and field multiple thousands of all-domain, attritable autonomous (ADA2) systems within an aggressive timeframe to counter peer adversary mass.³

However, a critical strategic vulnerability exists within this paradigm shift: the procurement and manufacturing of uncrewed airframes are vastly outpacing the industrial capacity to arm them. The defense apparatus exhibits a tendency to focus heavily on the aerial platforms themselves—prioritizing software, autonomy, and flight characteristics—while systematically underestimating the industrial base required to mass-produce miniaturized precision micro-munitions, modular warheads, and the highly specialized precursor materials they require.⁷ A drone without a reliably sourced, mass-producible munition is relegated to an intelligence, surveillance, and reconnaissance (ISR) role. While ISR remains vital, the strategic intent of modern initiatives is to deliver long-range, distributed kinetic effects.³

This report provides DoD leadership with an objective strategic analysis of the drone-specific munitions and payload supply chain. It moves beyond the visible tier-one prime contractors to detail the fragile, sub-tier dependencies in critical materials, energetics, and propulsion systems.⁸ Furthermore, it examines the imperative of modular open systems architectures to break vendor lock and scale payload production alongside commercial platform scaling.¹⁰ Finally, it addresses the severe logistical complexities of rearming these autonomous fleets within the context of Distributed Maritime Operations (DMO) and Expeditionary Advanced Base Operations (EABO).¹² In these operational models, the traditional concentration of explosive material in hub-and-spoke supply depots is both tactically hazardous and logistically unfeasible.¹⁵ To successfully enable warfighters with necessary kinetic effects, leadership must recognize that scaling the drone fleet is strategically ineffective without simultaneously scaling the specialized industrial base and logistical networks that manufacture and deliver their lethal payloads.

2. The Platform-Munition Acquisition Imbalance

The modern operational environment demonstrates that mass and attrition have returned as defining characteristics of conventional conflict. Observation of recent high-intensity conflicts reveals staggering consumption rates of both loitering munitions and precision-guided weapons.¹⁷ In these environments, the daily expenditure of precision assets routinely exceeds the monthly or even annual production capacities of Western industrial bases.¹⁷

The DoD has recognized this reality, initiating programs designed to inject mass into the Joint Force. The Replicator initiative aims to field thousands of autonomous systems to offset adversary advantages in mass and geographic positioning.³ Tranche 1 and Tranche 1.2 of the Replicator initiative specifically target the accelerated fielding of loitering munitions, such as the Switchblade-600 and the Altius-600, alongside company-level small uncrewed aerial systems (sUAS) like the Anduril Industries Ghost-X and Performance Drone Works C-100, which are capable of carrying modular payloads.³

Yet, a fundamental imbalance persists in the acquisition ecosystem. The industrial barriers to producing a basic autonomous airframe or quadcopter are relatively low, often leveraging commercial off-the-shelf (COTS) components and civilian manufacturing processes. Conversely, the barriers to producing the kinetic payloads—the warheads, the precision seekers, and the fusing mechanisms—are exceptionally high. The U.S. defense industrial base (DIB) for uncrewed systems is currently categorized as highly fragile, suffering from limited competition, demand uncertainty, and a critical reliance on foreign sources for core components.⁹

2.1. Budgetary Allocations and Priorities

An analysis of the DoD’s Fiscal Year (FY) 2025 budget request highlights the scale of investment in systems and munitions. The request totals $310.7 billion for procurement and research, development, test, and evaluation (RDT&E).¹ While munitions and missiles receive substantial funding, the underlying industrial capacity to absorb these funds and output physical units remains constrained.

FY 2025 Investment Category	Requested Funding ($ Billions)	Percentage of Total Investment
Aviation & Related Systems	$61.2	19.7%
Shipbuilding & Maritime Systems	$48.1	15.5%
Missiles & Munitions	$29.8	9.6%
Space Based Systems	$25.2	8.1%
C4I Systems	$21.1	6.8%
Science & Technology	$17.2	5.5%
Missile Defense Programs	$13.5	4.3%
Ground Systems	$13.0	4.2%
Mission Support Activities	$81.5	26.2%
Total	$310.7	100%

Data Source: DoD Comptroller, FY2025 Weapons Investment Report.¹

Furthermore, defense officials have indicated that proposed future budgets, extending into FY 2027, will allocate over $70 billion specifically for military drones and counter-drone weapon systems, representing the largest investment in drone warfare in U.S. history.² Within this long-term planning, approximately $53.6 billion is slated for autonomy, platforms, and contested logistics, while $21 billion is earmarked for munitions and counter-drone technologies.² This financial commitment requires a commensurate expansion of the physical industrial base to produce the required hardware.

2.2. The Fragility of the Uncrewed Systems DIB

A systematic evaluation by the RAND Corporation indicates that the U.S. uncrewed systems industrial base is fundamentally “more fragile than it is critical”.⁹ This terminology suggests that the primary risk lies in the potential loss of existing capabilities rather than the difficulty of replacing them once lost. Factors contributing to this fragility include demand uncertainty, which discourages long-term capital investment by private firms; market concentration, wherein a very limited number of firms are capable of building systems at scale; and significant reliance on foreign sources for selected critical components.⁹

While large prime contractors manage visible risks efficiently, fragility accumulates invisibly at the lower tiers. Small, capital-constrained firms responsible for specific components face single-source dependencies and limited surge capacity.⁸ When demand signals are chaotic and unpredictable, these sub-tier suppliers cannot afford to retain the latent production capacity required to scale up in an emergency.¹⁷

2.3. Historical Context: The Arsenal of Democracy vs. The Knowledge Economy

To contextualize the current industrial shortfall, it is necessary to examine historical defense mobilization. During World War II, the “Arsenal of Democracy” successfully produced nearly 300,000 aircraft and 86,000 tanks.²⁰ This feat was achievable because the U.S. economy was heavily rooted in manufacturing, and latent production capacity existed across civilian sectors that could be rapidly retooled for defense.²⁰ The War Production Board provided a unified, coherent demand signal that eliminated market risk for private companies, guaranteeing material allocations and contracts.¹⁷

By contrast, the contemporary U.S. economy is primarily knowledge-based.²⁰ Decades of policy choices prioritizing peacetime efficiency and just-in-time logistics have eroded the domestic manufacturing base.¹⁷ The defense industrial base is deeply entangled with global supply chains, often relying on adversary-controlled markets for raw materials.⁷ To field the payloads required for modern drone fleets, the DoD cannot rely on latent civilian capacity; it must deliberately construct and secure a dedicated, modernized supply chain.

3. Structural Vulnerabilities in Sub-Tier Material Supply Chains

A modern military drone and its associated kinetic payload rely fundamentally on complex metallurgy and advanced chemistry. The global supply chain for these raw materials is heavily entangled with markets managed by peer competitors, translating supply chain competition into a geopolitical battle for the raw inputs required to employ drones at mass scale.⁷

3.1. Sensors and Seekers: The Precision Bottleneck

The efficacy of a precision micro-munition relies entirely on its ability to autonomously or semi-autonomously locate, fix, and track targets. This requires advanced sensors and seekers, which are bound by distinct material chokepoints.⁷

• Infrared Detectors: High-fidelity thermal seekers are critical for terminal guidance and targeting in contested environments where GPS or visual spectrums are degraded. These seekers rely heavily on highly specialized materials, namely indium antimonide and mercury cadmium telluride.⁷
• Datalinks and Amplifiers: The communication architectures that allow drone swarms to coordinate, or human operators to authorize strikes via “human-in-the-loop” systems, require immense bandwidth and power efficiency. Gallium-Nitride (GaN) power amplifiers are foundational to these datalinks, enabling remote operation and sensor feedback.⁷
• Semiconductor Fabrication: The flight controllers, mission computers, and navigation systems depend on specialized semiconductors. The fabrication facilities for these specific defense-grade chips are complex and limited in number. They require years of capital investment to expand, meaning they cannot organically surge production to meet sudden wartime demands or absorb the shock of global export controls.⁷

3.2. Propulsion Dependencies

Whether for the carrier platform or a specific loitering munition, propulsion relies on materials that are acutely vulnerable to geopolitical weaponization.

• Rare-Earth Magnets: The electric motors providing lift and torque for most sUAS and loitering munitions rely on neodymium-iron-boron (NdFeB) magnets.⁷ Currently, approximately 90% of the global output for these magnets is concentrated in China. Even when the raw materials are mined in allied nations, the complex magnetization and finishing processes remain largely under foreign control, exposing the U.S. to severe disruption.⁷
• Mini-Jet Engines: For longer-range, deep-strike drones and high-speed loitering munitions, electric motors are insufficient, necessitating miniaturized turbojet engines. Currently, there is a massive production bottleneck in Europe and North America for these mini-jet engines.²² These are technically demanding systems built with lightweight alloys and advanced manufacturing methods, including 3D-printed components. Because they were not produced at scale prior to recent global conflicts, European and allied manufacturers—such as Czech-based PBS Group—are stretched to their limits trying to fulfill demand.²³ This creates a structural supply-chain deficit that strictly limits the total number of missile drones that can be fielded.²²

3.3. Structural Materials for Payloads

To maximize the lethality of a micro-munition, the weight of the delivery vehicle must be absolutely minimized. This requires aerospace-grade carbon fiber for the skeletal foundation and specialized alloys, such as aluminum-lithium, to ensure structural integrity while preserving weight margins for the explosive payload.⁷ The global production capacity for these specific alloys and composites is limited and cannot be rapidly scaled in a crisis.

Critical Material / Subsystem	Primary Function in Drone Payloads	Identified Supply Chain Vulnerability
Indium Antimonide / Mercury Cadmium Telluride	Infrared detection and terminal guidance for seekers.	Highly specialized material sourcing; difficult to surge domestic production.7
Gallium-Nitride (GaN)	Power amplification for resilient datalinks and C2.	Sub-tier foreign dependency; critical node in swarm architecture communications.7
Neodymium-Iron-Boron (NdFeB)	High-torque, lightweight motor magnets for propulsion.	~90% of global output and finishing controlled by single peer adversary.7
Mini-Turbojet Engines	High-speed transit for deep-strike loitering munitions.	Severe European and US manufacturing bottleneck; lack of established producers.22
Carbon Fiber & Aluminum-Lithium	Weight reduction to maximize explosive payload capacity.	Constrained global fabrication capacity; reliant on complex metallurgy.7

4. The Energetics and Advanced Manufacturing Crisis

While sensors guide the weapon and airframes carry it, energetics provide the actual kinetic effect. The capacity to produce the explosive compounds and propellants required for micro-munitions is arguably the most severe constraint facing the U.S. defense industrial base. The production of drone-specific munitions introduces unique vulnerabilities related to precursor chemicals and weight-optimization requirements.⁷ To maximize lethality on a small platform, energetics must yield high energy output from minimal mass, necessitating advanced chemical formulations.

4.1. The Antiquated Energetics Infrastructure

The U.S. military heavily relies on Government-Owned, Contractor-Operated (GOCO) Army Ammunition Plants (AAPs) to produce energetics, small-caliber ammunition, and high-explosive artillery.²⁵ These facilities have served as the backbone of the arsenal since World War II. Consequently, much of the foundational technology and process infrastructure remains antiquated. For example, the domestic production of RDX and HMX—two of the primary energetic chemicals relied upon by the U.S. military since the 1940s—still utilizes the WWII-era Bachmann process at facilities like the Holston Army Ammunition Plant.²⁶

Relying on 80-year-old manufacturing processes severely limits production throughput and creates single points of failure. The loss of access to even a single precursor chemical could halt the production of an entire class of drones and their payloads. Furthermore, the Department of Defense currently lacks comprehensive visibility below the tier-one contractor level to identify these specific precursor risks.⁷

The National Energetics Plan details the actions required to maintain technical superiority, highlighting systemic challenges.²⁷ Among these are insufficient coordination between science and technology (S&T) and acquisition communities, which stifles the transition of advanced energetics to operational use. Additionally, antiquated Test and Evaluation (T&E) standards fail to accurately characterize the effects of advanced energetic materials designed for extended range and lethality.²⁷

4.2. Modernization Initiatives and the Munitions Campus Model

Recognizing this critical shortfall, the Army has initiated a 15-year Organic Industrial Base (OIB) Modernization Plan, representing an investment of approximately $18 billion to modernize facilities, infrastructure, and retool processes across its 23 arsenals, depots, and ammunition plants.²⁸ As part of this effort, the Joint Program Executive Office for Armaments and Ammunition (JPEO A&A) is leveraging digital engineering and Model-Based Systems Engineering (SysML) to identify process bottlenecks and optimize throughput at these legacy facilities.²⁵

Furthermore, the DoD is exploring public-private partnerships to bypass the limitations of legacy infrastructure. A prime example is the recent groundbreaking of the Munitions Campus in Bloomfield, Indiana.³¹ Supported by a $75 million award from Defense Production Act Title III funding, this campus introduces a shared-infrastructure model that collocates manufacturers of major components, subcomponents, and energetics—such as solid rocket motors (SRMs)—to streamline the supply chain. Prometheus Energetics LLC serves as the anchor tenant for this 1,100-acre development. By clustering industrial capacity in close proximity to the Crane Army Ammunition Activity and Naval Surface Warfare Center Crane, the DoD aims to enable faster, more cost-effective scaling of munitions output across various weapon systems.³¹

4.3. The Workforce Deficit in Advanced Manufacturing

Capital investment in infrastructure cannot yield results without a highly skilled workforce. The production of uncrewed systems and their payloads suffers from critical labor shortages in specialized trades. Assessments of the defense-oriented advanced manufacturing landscape reveal profound deficits in skills related to welding, forging, metal casting, and advanced electronics soldering.⁹

Initiatives such as the Advanced Manufacturing Training Program in Massachusetts and DoD Manufacturing Technology (ManTech) engagements with the Advanced Robotics for Manufacturing (ARM) Institute are attempting to close these gaps through targeted workforce development grants and gap analyses.³² However, training a workforce capable of executing modern, tight-tolerance manufacturing for micro-munitions operates on a multi-year horizon, compounding the immediate challenge of scaling production for rapid fielding initiatives.

5. Overcoming Vendor Lock: Payload Modularity and Open Architecture

To scale payload availability rapidly, the DoD must decouple the development of the drone airframe from the development of the munition. Historically, uncrewed systems and their payloads have been highly proprietary and mission-specific. While some systems offer swappable payloads, these are rarely interchangeable across different manufacturers, leading to “vendor lock.” If a unit requires a different kinetic effect, it is often forced to procure an entirely new drone system from the original manufacturer.¹¹

5.1. The Modular Open Systems Approach (MOSA)

The strategic solution to this bottleneck is the enforcement of a Modular Open Systems Approach (MOSA). MOSA is a technical and business strategy that adopts open standards to create highly cohesive, loosely coupled system structures.¹⁰ By standardizing the interfaces between the vehicle and the payload, the DoD can stimulate intense competition among sub-tier suppliers. Small, specialized tech firms can design innovative micro-munitions or sensors without needing to engineer a flight-capable drone, while airframe manufacturers can focus on range, endurance, and cost-efficiency.³⁷

MOSA adoption is a key focus driven by the National Defense Authorization Act, establishing legal requirements under Title 10 U.S. Code 2446a.(b).¹⁰ Existing standards under the MOSA umbrella include Open Mission Systems (OMS) for aviation weapons, Future Airborne Capability Environment (FACE) for software, and Weapon Open Systems Architecture (WOSA) for munitions development.³⁸

5.2. Standardization Interfaces: Picatinny CLIK and Mod Payload

Translating MOSA from concept to physical reality requires exacting engineering standards specifically tailored for uncrewed platforms. Two prominent developments are shaping the weaponization of uncrewed fleets:

• Picatinny Common Lethality Integration Kit (CLIK): Developed by the DEVCOM Armaments Center, the Picatinny CLIK specification establishes a universal standard for weaponizing sUAS. In the same way the Picatinny Rail standardized rifle accessories, CLIK explicitly defines the physical mechanical attachment, the electrical power and network interfaces, and the safety-critical architecture required between the ground control station, the drone, and the lethal payload.¹¹ By adhering to this standard, warfighters can swap payloads on the battlefield using common connections, adapting COTS drones into strike assets. The goal is to eliminate unique integration methods and costly acquisition conditions created by proprietary designs.¹¹
• Mod Payload Standard: Managed by a government and industry team led by the Johns Hopkins Applied Physics Laboratory (JHU APL), this standard focuses on true plug-and-play interoperability for electronic warfare, signals intelligence, and communications payloads.⁴² The latest update, revision 6.1, expands Mod Payload to unmanned surface vehicles (USVs) and dismounted personnel, streamlining access for industry and allied partners.⁴²

The operational impact of these standards is already visible. For example, systems like the AeroVironment VAPOR CLE helicopter UAS utilize the CLiK interface to integrate modular lethal payloads, including 60mm/81mm mortar conversion kits and 40mm munitions.⁴³ Saab and other defense contractors are developing adaptable warheads designed to insert into loitering munitions to optimize effects against specific targets.⁴⁴ This paradigm shift ensures that as new, highly effective energetics or warhead designs are developed, they can be immediately fielded across the existing fleet of diverse drones without requiring platform redesigns.⁴¹

Modularity Standard	Developing Agency / Authority	Primary Application	Strategic Benefit
MOSA	DoD / Congressional Mandate	Broad defense acquisition framework.	Promotes competition, reduces lifecycle costs, ensures interoperability.10
Picatinny CLIK	DEVCOM Armaments Center	Physical, electrical, and safety integration of lethal payloads on sUAS.	Eliminates vendor lock; enables field-swappable kinetic effects using COTS platforms.11
Mod Payload	JHU APL / USSOCOM	Electronic warfare, SIGINT, and comms payloads across UxS.	Drives down development costs and slashes integration timelines for non-kinetic systems.42
WOSA	DoD Wide	Munitions development architecture.	Standardizes internal architecture of precision weapons.38

6. Expeditionary Logistics and Distributed Rearming

The procurement of munitions is only the preliminary challenge; delivering, storing, and loading those munitions onto drone platforms in contested, distributed environments presents an equally daunting systemic hurdle. Current U.S. operational concepts for peer conflict, specifically Distributed Maritime Operations (DMO), Expeditionary Advanced Base Operations (EABO), and Littoral Operations in a Contested Environment (LOCE), mandate that forces disperse across vast geographic areas—such as the archipelagos of the Indo-Pacific—to complicate adversary targeting.¹²

6.1. The Tyranny of Distance and Austere Storage

DMO and EABO fundamentally disrupt traditional logistical models. Large, centralized supply depots and established field trains present unacceptably massive targets for adversary long-range precision fires and loitering munitions.¹⁵ Historically, logistical responses relied on a “hub-and-spoke” framework, where large aircraft or ships delivered supplies to a central node, and smaller assets distributed them outward.⁴⁷ In a contested environment saturated with intelligence, surveillance, and reconnaissance (ISR) drones, this massing of sustainment assets close to the forward line of troops guarantees rapid attrition.¹⁵

Consequently, forces must operate from temporary, austere locations. This dispersion creates severe challenges for the storage and handling of explosive munitions. Ammunition storage is governed by stringent safety regulations, such as the Defense Explosives Safety Regulation (DESR 6055.09) and DDESB standards.⁴⁸ These regulations mandate specific asset preservation distances and minimum separation distances to prevent catastrophic chain reactions in the event of an incident or attack.⁵⁰ On small, non-contiguous terrain features or littoral islands, adhering to these explosive safety footprints while maintaining a concealed, low-signature posture is exceptionally difficult.⁵¹ The time-space challenge of separated units requires additional distribution capacity to ensure constant, concealed deliveries without creating targetable supply dumps.⁵²

6.2. Rearming at Sea: The TRAM Initiative

For maritime operations, a fleet dispersed for DMO expends its vertical launch system (VLS) munitions rapidly. By dispersing combat power beyond carriers to destroyers and frigates, the Navy forces adversaries to search wider areas, but this also distributes the demand for munitions.¹³ Historically, once a surface combatant depleted its VLS cells, the warship had to withdraw from the theater and travel long distances to a secure port to reload, removing critical combat power from the fight and exposing the vessel during transit.⁵⁴

To counter this, the Navy has prioritized the Transferable Reload At-sea Method (TRAM). Recently demonstrated off the coast of California, TRAM enables cruisers and destroyers to rearm their MK 41 VLS canisters while underway, connecting to Military Sealift Command dry cargo ships in the open ocean.⁵⁴ During the demonstration, the USS Chosin teamed up with the USNS Washington Chambers to transport and load a missile canister using the TRAM device along rails connected to the VLS modules.⁵⁴ By fielding TRAM within the next two to three years, the Navy will maintain persistent forward-strike capacity, effectively keeping distributed assets in the fight without severing their logistical tethers.⁵⁴

In contested environments, traditional ‘hub-and-spoke’ logistics are replaced by dynamic resupply networks. TRAM allows underway reloading of warships, while uncrewed logistics systems (ULS-A) distribute precision payloads to decentralized island outposts, circumventing centralized depots entirely.

6.3. Uncrewed Logistics and the “Zero Line”

Resupplying the “zero line” or Forward Line of Troops (FLOT) has become exceptionally lethal due to ubiquitous adversary ISR and drone saturation.¹⁶ To mitigate the risks of moving heavy logistical convoys, the DoD is developing Unmanned Logistics Systems-Air (ULS-A) and Unmanned Ground Vehicles (UGVs) to execute tactical resupply.⁵⁹

These autonomous logistical platforms can move ammunition, batteries, and drone payloads to distributed units across non-contiguous terrain without risking human crews.⁴⁶ The Marine Corps Aviation Plan highlights the necessity of vertical and connected replenishment from Combat Logistic Fleet vessels to support distributed aviation operations.⁶² Furthermore, research is advancing toward automated rearming systems, where a large UGV can carry fuel and munitions to automatically launch, recover, and rearm smaller vertical take-off and landing (VTOL) drones at forward locations.⁶³ This extends the operational reach of the drone fleet while keeping human operators safely distanced from the launch signature, a concept critical to controlling the “atmospheric littoral”—the low-altitude airspace that enhances ground maneuverability.⁶³

However, the realization of large-scale autonomous ground vehicle operations remains challenging. While programs like DARPA’s RACER (Robotic Autonomy in Complex Environments with Resiliency) have demonstrated successful autonomous breaching exercises using modified Textron Ripsaw M5 vehicles, widespread operational deployment is estimated to be years away, hindered by undefined requirements and the complexities of off-road autonomy.⁶¹

7. Scaling Production: From Artisanal Assembly to Mass Output

The ultimate test of the defense industrial base is the transition from low-rate initial production—often characterized by artisanal, highly manual assembly—to rapid, automated mass output. Current Western munitions stockpiles, optimized for low-intensity conflicts over the last two decades, are widely considered insufficient for a sustained peer conflict.⁶⁵

7.1. The Cost and Rate Paradigm

Traditional precision-guided munitions (PGMs) are exquisite, highly effective, and exceedingly expensive to produce. For instance, a single Patriot PAC-3 MSE interceptor costs approximately $3.9 million, while a THAAD interceptor costs $15.5 million.⁶⁵ These systems require years of lead time from contract award to delivery, meaning depleted stockpiles cannot be quickly replenished.⁶⁵ In contrast, the operational environment demands high-volume, low-cost offensive capabilities that can overwhelm defensive systems through sheer numbers—a concept referred to as the “Uberization of warfare”.¹⁸

Loitering munitions bridge this gap by compressing the kill chain into a single, expendable platform that combines the airframe, the sensor, and the warhead.²¹ They provide a cost-effective alternative to multi-million-dollar PGMs, freeing up exquisite systems for high-value targets while utilizing affordable mass to strike dispersed armor and personnel.²⁴ As noted in recent analyses, the ability to strike with precision from a distance is no longer reserved for superpowers; low-cost long-range precision weapons like the Shahed 136 have revolutionized strike dynamics, initiating an arms race for the least expensive precision systems.⁶⁸

7.2. Industrial Surge Examples

Achieving mass requires unprecedented scaling efforts by industry partners. AeroVironment, a primary producer of loitering munitions such as the Switchblade series, provides a current case study in industrial surging. Recognizing the anticipated demand driven by global conflicts and DoD initiatives like the Low Altitude Stalking and Strike Ordnance (LASSO) program, the manufacturer accelerated production of the Switchblade 600 from 40 systems per month to 240 systems per month.⁶⁹

To prepare for future demands, the company is investing in a next-generation manufacturing facility in Salt Lake City, Utah, intended to boost capacity to over 1,200 units per month, or roughly 14,400 drones annually.⁷⁰ This expansion comes alongside significant DoD contracts, including a $186 million delivery order for Switchblade 600 Block 2 and 300 Block 20 systems equipped with explosively formed penetrator (EFP) payloads.⁷¹

Simultaneously, munitions like the GBU-69/B Small Glide Munition, engineered for precision strikes with a substantial blast-fragmentation warhead, are being integrated across uncrewed platforms like the MQ-1C Gray Eagle and MQ-9A Reaper.⁷² Developed by Dynetics and USSOCOM, the SGM represents a tailored approach to equipping platforms with standoff precision capabilities, though procurement scaling must continuously align with future conflict priorities.⁷³

7.3. Strategic Frameworks for Resilience

To support these industrial surges and mitigate vulnerabilities, the DoD is implementing the National Defense Industrial Strategy (NDIS). This strategy, and its associated Implementation Plan, details actions to build resilience, reshore critical supply chains, and foster advanced manufacturing techniques to ensure that the capacity to build munitions matches the strategic imperative to employ them.⁷⁴ This includes specific funding through the Defense Production Act Title III, Industrial Base Analysis and Sustainment, and investments in munitions production to secure supply chains.⁷⁴

8. Strategic Recommendations for DoD Leadership

The Department of Defense’s investments in uncrewed technologies risk profound operational underperformance if the platforms arrive at the tactical edge without the necessary kinetic payloads. To ensure warfighters possess the required kinetic effects in a peer conflict, DoD leadership must address the systemic requirements of the munition supply chain with the same urgency applied to drone acquisition.

The analysis yields the following strategic imperatives:

1. Map and Secure Sub-Tier Dependencies: The DoD must gain comprehensive visibility into the tier-three and tier-four suppliers of critical materials. Action is required to secure the supply of Gallium-Nitride for datalinks, specialized semiconductors, and the precursor chemicals required for advanced energetics. Furthermore, investments must be directed to reshore or “friend-shore” the processing of Neodymium-Iron-Boron magnets and the manufacturing of mini-turbojet engines, which currently present severe bottlenecks in the production of high-speed loitering munitions.
2. Mandate Open Architecture for Payloads: Initiatives like Replicator must strictly enforce Modular Open Systems Approaches (MOSA) across all procured platforms. By mandating adherence to interface standards such as the Picatinny CLIK and Mod Payload, the DoD can ensure that any procured sUAS can natively accept a wide variety of modular warheads and sensors. This effectively eliminates vendor lock, allowing the munitions industrial base to innovate and scale independently of the airframe manufacturing base.
3. Accelerate Energetics Modernization: The 15-year Organic Industrial Base Modernization Plan is a necessary endeavor, but its timeline is misaligned with the immediate threat environment. The DoD must accelerate the transition away from antiquated chemical processes by stimulating private capital and expanding public-private partnerships, such as the Munitions Campus model. Clustering the production of specialized propellants, solid rocket motors, and explosive compounds will reduce supply chain friction and scale output. Additionally, concerted efforts must continue through ManTech to address the critical workforce deficits in advanced manufacturing.
4. Integrate Rearming Logistics into Platform Procurement: A drone fleet is only as effective as its reload capacity. As the Joint Force embraces Distributed Maritime Operations and Expeditionary Advanced Base Operations, the logistics of rearming must be treated as a primary warfighting function. Continued investment in at-sea reloading mechanisms like TRAM is essential to sustain naval strike power. Simultaneously, the development and fielding of uncrewed logistics systems (ULS-A and UGVs) must be accelerated to safely distribute containerized payloads and rearm platforms at the austere, dispersed locations mandated by modern operational concepts.

The tendency to fixate on the technology of the drone itself obscures the reality that an uncrewed system is merely a delivery mechanism. The true center of gravity in autonomous warfare is the industrial capacity to mass-produce, securely transport, and reliably integrate the miniaturized precision munitions that deliver the decisive tactical effect. Scaling the fleet without concurrently scaling the specialized munitions supply chain will yield a force that is technologically advanced, but kinetically hollow.
