United States Defense Market Analysis by Mordor Intelligence

The United States defense market size was valued at USD 354.5 billion in 2026 and estimated to grow from USD 367.4 billion in 2027 to reach USD 449.6 billion by 2032, at a CAGR of 4.12% during the forecast period (2027-2032).

Missile replenishment and unmanned-vessel procurement in the United States create demand for both production volume and new military capabilities. AI-enabled intelligence extends the operational role of software by delivering detections through existing service and command tools. Suppliers can address these requirements through specialized components and expanded domestic manufacturing. Production ceilings and shipyard skills shortages constrain how quickly spending becomes usable military capability. Near-term revenue opportunities therefore favor suppliers able to deliver awarded missile and vessel orders, while software providers can pursue sales through integration with tools military users already run.

United States Defense Market Segment Analysis

By Armed Forces:

Army Scale Meets Air Force Modernization

The Army accounted for a 40.23% share of the United States defense market size in 2026, making it the largest segment. On September 3, 2025, it finalized a USD 9.8 billion multiyear contract with Lockheed Martin Missiles and Fire Control. The agreement covered FY2024-FY2026 and procurement of 1,970 PAC-3 MSE missiles and associated hardware for US and international partners. Combining missile volumes and associated hardware makes manufacturing throughput and component coordination part of the same commercial commitment. The multiyear scope gives missile and associated-hardware suppliers a common order horizon across the Army-led program.

The Air Force is forecast to be the fastest-growing segment, with a 5.4% CAGR during 2027-2032. In May 2026, it awarded Boeing USD 219 million for the first 14 T-7A production trainers and associated support. Spare parts, support equipment, and training were included after the April 23 decision clearing the aircraft for low-rate production. Because spares, support equipment, and instruction accompany the first lot, the commercial scope extends to preparing the Air Force to use its new trainers.

United States Defense Market: Market Share by Armed Forces, 2026

By Type:

Platform Scale and Unmanned Procurement Growth

Military platforms represented a 39.08% United States defense market share in 2026, making them the largest segment by type. The US F-35 fleet grew from about 450 aircraft in FY2021 to more than 800 in FY2025. On July 29, 2026, the Navy awarded General Dynamics Electric Boat, a General Dynamics business unit, USD 29.5 billion for 5 additional Columbia-class submarines. The package also awarded the business USD 42.1 billion for 9 additional Virginia-class submarines, alongside separate infrastructure support. Aircraft fleet counts and submarine contract values capture different commercial exposures, so a small hull order can carry substantial supplier commitments alongside a much larger aircraft base.

Unmanned systems are forecast to be the fastest-growing segment, at an 8.3% CAGR during 2027-2032. The PRIME program generated a production contract for more than 200 small unmanned surface vehicles supporting INDOPACOM. The program fielded 66 vehicles in 2025 under a USD 392.4 million contract ceiling. The Defense Innovation Unit and Naval Sea Systems Command’s Program Manager, Ships (PMS) 420, transitioned the program from prototyping through validation to production in under 15 months. Fielding 66 of the more than 200 ordered vehicles in 2025 moved the program beyond prototyping, anchoring supplier revenue opportunities in deliveries against an awarded production order.

By Domain:

Land Procurement and Space Architecture Diverge

Land was the largest segment by domain, with 40.17% of the market in 2026. For FY2027, the Department of Defense requested USD 1.16 billion in budget authority and 196 Armored Multi-Purpose Vehicles, a tracked ground-system program. The requested annual quantity would create repeated construction work for tracked-vehicle suppliers if it becomes an order. Because these figures are a request, the 196 vehicles represent a potential production pipeline whose timing depends on funding and contracting.

Space is projected to be the fastest-growing segment, at a 7.3% CAGR during 2027-2032. On July 13, 2026, the Space Development Agency awarded 2 prototype agreements totaling approximately USD 1.75 billion for 36 space vehicles. The awards comprised 18 missile-warning and tracking vehicles and 18 missile-defense vehicles across 4 orbital planes. Future operations and sustainment belong to the Space Force, linking the awarded hardware to an eventual military operating architecture. Because the awards support Golden Dome’s space-based capabilities, the 18 missile-warning and tracking vehicles and 18 missile-defense vehicles tie this demand to missile-defense sensing rather than to satellite volume alone.

By Procurement Nature:

Domestic Completion Capacity Expands

Indigenous production was the largest segment, with 70.45% of the market in 2026, and is forecast to be the fastest-growing segment, at a 5.45% CAGR during 2027-2032. The Army and General Dynamics opened a facility in Camden, Arkansas, on April 22, 2025. It contained 2 new lines for the final loading, assembly, and packing of 155 mm high-explosive artillery munitions. The added lines broaden the Army’s domestic production base at the completion stage, so their ramp-up governs how quickly this investment contributes deliverable rounds.

For foreign procurement, DoD buyers report foreign-manufactured end products under categories including qualifying-country products, domestic nonavailability, trade-agreement eligibility, and unreasonable domestic cost. Under FAR 25.103(c), a contracting officer may acquire a foreign end product when domestic cost is determined unreasonable under the specified evaluation rules. This route makes the domestic-price assessment commercially relevant to a foreign supplier’s offer. A lower foreign price alone does not settle the opportunity, because the officer’s applicable cost determination governs whether this exception can be used.

Geography Analysis

Connecticut and Virginia anchor substantial submarine supplier networks, giving the industrial geography a strong naval production component. The Submarine Industrial Base Council identified 342 submarine industrial base suppliers in Connecticut in its 2026 state coverage. Virginia’s corresponding coverage included 285 submarine industrial base suppliers, establishing another extensive network within the same equipment category. Connecticut’s larger listing and Virginia’s comparable supplier count spread submarine subcontract participation across 2 states rather than a single hub.

In Texas, the Army awarded Hadrian Automation the first phase of an advanced manufacturing project at Red River Army Depot in Texarkana in March 2026. Work aimed at modernizing weapon-system component production, including small unmanned aircraft systems, was scheduled for completion by March 16, 2027. Ohio added a distinct production milestone on July 27, 2026, when Anduril’s first Ohio-built Fury semi-autonomous fighter, developed for the Air Force, rolled off the Arsenal-1 line in Pickaway County. The commercial contrast is between depot component modernization and complete-aircraft production, giving suppliers different industrial entry points within the shift toward automated manufacturing and unmanned capabilities.

California and West Virginia illustrate how defense production extends beyond complete platforms to specialized payloads and missile integration. Boeing opened an electro-optical/infrared payload line in El Segundo to support Millennium Space Systems’ scheduled delivery of 12 Space Force missile-warning and tracking medium Earth orbit vehicles in 2027. Northrop Grumman opened a production and assembly center at Allegany Ballistics Laboratory within the Naval Industrial Reserve Ordnance Plant in Rocket Center, West Virginia, on September 25, 2025. The new center was intended to expand advanced strike missile production capacity. Specialized completion work gives these locations a commercial role within larger defense programs, allowing participation through a particular manufacturing stage rather than an entire platform build.

Regulatory Framework and Outlook

The comparison covers selected jurisdictions from the perspective of defense contractors operating mission-critical facilities. Federal acquisition requirements govern contractor participation, while Virginia adds a qualified operating allowance for mission-critical emergency generators. Federal cybersecurity assessment duties attach to applicable contracts, while Virginia’s air-rule allowance attaches to certified generators, so the comparison shows distinct compliance concerns for the same contractor.

Regulatory Table of United States Defense Market

Regulatory Table of United States Defense Market
Decision factor United States Virginia
Primary authority Department of Defense Virginia Department of Environmental Quality (DEQ)
Key instruments or direction Defense Federal Acquisition Regulation Supplement (DFARS) and CMMC Phase I self-assessments for applicable contracts 9VAC5-80-1111 and related 9VAC5-540 amendments
Commercial effect Contractor qualifications and applicable cybersecurity self-assessment duties Up to 50 hours per year of specified non-emergency generator operation with required mission-critical certification
Current policy attractiveness Medium Medium
Future direction of policy attractiveness Easing No change
Source: Mordor Intelligence

Federally, the July 13, 2026, suspension of CMMC Phase II paused the planned November 10, 2026, third-party assessment step for contracts involving sensitive but unclassified information. The suspension eases the planned assessment sequence, while Phase I self-assessments that remain in force for applicable contracts keep the federal rating at Medium. Virginia’s generator owners retain certifications for the generator’s life and revise and submit them when qualification ends, while listed emergency operations fall outside the 50-hour annual allowance. Virginia’s rule effective June 16, 2025, established the conditional 50-hour allowance on and off military installations, and the allowance remains in force, supporting No change, while required DoD or armed-service certification to DEQ and federal engine compliance justify Medium.

Value Chain Stages

The comparison follows defense equipment from development through manufacturing to support during military service. Northrop Grumman’s aircraft business designs, produces, integrates, sustains, and modernizes aircraft for the Air Force, Navy, and other customers. Those linked capabilities create several earning points within one program, so commercial value extends beyond the initial equipment sale.

Value Chain Analysis Table of United States Defense Market

Value Chain Analysis Table of United States Defense Market
Primary activity Key participants Value capture Bottleneck Resilience response
System design and development Aircraft and weapons developers such as Northrop Grumman Corporation and Lockheed Martin Corporation Engineering and development contract revenue Translating designs into repeatable production Include manufacturing requirements in development reviews
Manufacturing and systems integration Aircraft integrators such as Northrop Grumman Corporation; missile producers such as Raytheon, an RTX business Equipment sales and integration fees Throughput during production ramps Expand dedicated manufacturing capacity
Sustainment and modernization Military aircraft support providers such as Northrop Grumman Corporation and Lockheed Martin Corporation Sustainment and modernization contract revenue Coordinating support across different aircraft programs Use program-specific support teams
Source: Mordor Intelligence

Raytheon increased output by 20% across several critical programs in 2025, while RTX invested in additional Tucson munitions and sensor capacity. Additional factory capacity addresses the manufacturing bottleneck, while aircraft sustainment requires program-specific support capabilities. Production expansion can enlarge equipment sales without securing the subsequent service work, making lifecycle capabilities a separate source of value capture.

Competitive Landscape

Market Concentration

United States Defense Market Concentration

Competition is concentrated around established program suppliers whose specialized businesses perform distinct parts of the work. Lockheed Martin Corporation supplies missiles, while The Boeing Company produces PAC-3 seekers. General Dynamics Corporation participates in naval construction through NASSCO, while RTX Corporation’s Raytheon business supplies missiles and Northrop Grumman Corporation contributes to F-35 programs. In 2025, the Navy awarded Raytheon, an RTX business, a USD 1.1 billion contract for AIM-9X Block II missiles, with production set to rise to 2,500 missiles per year. Northrop Grumman reported USD 3.3 billion in new 2025 F-35 awards across its Mission Systems and Aeronautics Systems segments.

Supplier strategy can run through subsystem contracts when one contractor supplies a critical component to another’s program. On October 14, 2025, Boeing reported approximately USD 2.7 billion in multiyear contracts for more than 3,000 PAC-3 seekers, with deliveries planned at rates up to 750 annually through 2030. Boeing’s seeker role links the Army’s interceptor production targets to a component supplier working with Lockheed Martin, the PAC-3 interceptor prime. At up to 750 seekers a year, delivering more than 3,000 takes at least 4 years, which makes the seeker line a multiyear commitment tied to PAC-3 interceptor output.

Federal cloud security qualification is a separate regulatory consideration alongside the manufacturing capabilities of equipment suppliers. Govini’s Ark.ai, a defense-acquisition and analytics software service, earned FedRAMP Class D (High) certification on April 29, 2025. The credential applies to the cloud service offering. On August 21, 2025, the Army awarded Lockheed Martin USD 720 million for JAGM and HELLFIRE production for Army, Navy and international customers, the final follow-on under its multiyear contract. The follow-on award anchors Lockheed Martin’s competitive direction in production for several customer groups, while Ark.ai’s service-specific credential provides a security qualification around which Govini can seek federal analytics business.

Data Sources, Market Sizing, and Validation

Desk Research

Congressional Research Service summaries, such as its FY2025 budget request analysis, distinguish procurement, research and development, operations, and personnel appropriations, helping analysts separate contractor purchases from broader budget totals. GAO's defense industrial base reviews and the USAspending API provide evidence on awards, procurement records, supplier origin, and contract timing. SIPRI's military expenditure data offers a wider spending cross-check, while Navy program releases, such as its 2026 unmanned vessel procurement notice, can illustrate how awards translate into defined purchases.

Company annual filings, investor materials, and reputable defense and financial press can add program, product, delivery, and revenue context and can be checked against public award and budget records. The named sources are illustrative and not exhaustive, and further sources inform collection, validation and clarification.

Primary Interviews and Surveys

Analysts can interview US defense contractors, service acquisition and program personnel, and specialists in procurement, finance, manufacturing, and sustainment to clarify how awards, deliveries, and support contracts map to the defined market. Respondents can review secondary-source interpretations of procurement, research and development, modernization, and lifecycle support, identify omitted transactions or possible double counting, and explain changes in program timing or scope. Where evidence remains incomplete, analysts can compare award records, budget documentation, company disclosures, and independent program evidence, then seek targeted clarification from relevant respondent types.

Market-Sizing & Forecasting

The model estimates annual US defense purchases from a top-down view of government-funded capability and support transactions, using budget and contract evidence to distinguish actual purchases from appropriations that do not reach a counted sale. Procurement and modernization awards, research and development contract values, maintenance and repair activity, military construction and training purchases, and service-level delivery schedules provide market-specific indicators for the annual value and timing of demand. Analysts derive armed-force, product, domain, and procurement-nature shares from the stated buyer, transaction purpose, and program content, then check selected totals against supplier disclosures and sampled contract or channel evidence. Gaps in contract descriptions are classified from program documentation and clarified where possible, while unresolvable items are bounded and kept from being counted twice. Forecasts can use multivariate regression where a stable relationship links spending to these indicators, with scenario analysis for major program starts, delays, or funding shifts. Subject-matter respondents can test the direction and timing of variable-level forecasts and flag capacity or execution constraints without substituting opinion for documented values.

Data Validation & Update Cycle

Analysts triangulate award records, budget series, program documents, supplier disclosures, and independent military-spending signals, checking that each source refers to the same buyer, purchase stage, period, and dollar basis. They investigate anomalous year-to-year movements, missing contract values, duplicate program or subcontract reporting, and material differences between independent estimates, resolving each issue through source review and a second analyst review before sign-off. Analysts re-contact relevant respondent types when a source conflict, newly changed award, unclear transaction boundary, or material program delay could alter the estimate. They refresh the model annually, update it between annual cycles for material events, and complete a fresh source and calculation review before delivery.
