Description: Funding in this section will supercharge the U.S. Defense Industrial Base (DIB) by modernizing infrastructure and capacity to provide military capabilities at the speed and scale necessary for the U.S. to prevail in any conflict. These funds directly support the DoW’s execution of multiple Executive Orders supporting President Trump’s once-in-a-century revival of American industry, re-shoring strategic industries to the U.S., and revitalizing the industries that had been shipped overseas.

Critical Minerals: The $48.7 bi l l i o nin v es t m e n t in cr i t i c a l min er a l s in c l u d es :$ 24.3 billion for Industrial Base Analysis & Sustainment Program (IBAS) to expand capabilities and capacities in critical minerals including but not limited to rare earth elements; $6.4 bi l l i o n f or D e f e n se P r o d u c t i o n A c tP u r c ha ses (D P A P) t os t r e n g t h e nminin g, p r ocess in g, m e t a l l i z a t i o n, an d r ecy c l in g c a p abi l i t i esr e q u i r e d t os u pp or t c a p abi l i t i es a cr oss t h ee n t i r e d e f e n se in f r a s t r u c t u r e, a l l e v ia t e t h eD e p a r t m e n t^{'} sr e l ian ceo n f or e i g nma r k e t s, an d p r o v i d e ma t er ia l a v ai l abi l i t y t o mi t i g a t e a c t i v es h or t f a l l s a f f ec t in g d e f e n sesy s t e m r e a d in ess; an d$ 18.0 billion for the National Defense Stockpile (NDS) to fully resource the account to mitigate all critical materials risks. In today’s complex and rapidly evolving global security landscape, a strong and resilient defense industrial base is more critical than ever – critical minerals and materials underpin all capabilities across the Department. The IBAS and DPA critical minerals efforts include rare earth elements, essential alloying metals, minerals for microelectronic and battery applications, and any primary or recycled shortfall material used in defense systems. This includes over 50+ critical mineral commodities with thousands of defense and essential commercial applications. Rebuilding the NDS is an integral part of a multi-year strategy to address vulnerabilities in the DIB related to critical minerals. The NDS is a strategic tool in the broader DoW critical minerals risk mitigation portfolio.

Defense Production Act Purchases (DPAP): The $23.6 billion investment in DPAP provides financial incentives like loans, purchase commitments, and agreements to create and/or expand domestic production for critical capabilities required by the warfighter, such as kinetic weapons (including sub-tier supply chain capabilities for missiles and munitions, critical chemicals, and hypersonics), manufacturing (including castings, forgings, and other critical metal working capabilities), microelectronics (including secure advanced packaging, high-power, and radiation hardened devices), battery components, and those needed to address other industrial base shortfalls impacting areas such as space, air, ground, and soldier systems.

Industrial Base Analysis and Sustainment (IBAS): The $16.3 billion investment in the IBAS program represents a deliberate and necessary commitment to strengthening the Nation’s DIB and mitigating long-standing capacity, supply chain, and resiliency risks. This request places primary emphasis on kinetic capabilities, directly advancing Munitions Acceleration Council (MAC) priority missile systems and stabilizing critical sub-tier solid rocket motor (SRM) component suppliers that are essential to munitions production. These investments are purpose-built to reduce unit costs, expand and sustain surge capacity, and accelerate the qualification and fielding of integrated missile and SRM capabilities required to meet current and emerging operational demands. Concurrently, the IBAS funding will expand domestic and onshore production of critical chemicals, reducing dependence on adversarial sources, strengthening supply chain security, and ensuring the uninterrupted production of key weapon systems. This investment also advances other essential sectors of the industrial base, including manufacturing to increase production capacity; workforce development to address critical skill gaps and ensure a ready and capable labor force; energy storage and batteries to support next-generation operational requirements; microelectronics to secure trusted and resilient semiconductor supply chains; and chemicals and materials to ensure reliable access to critical inputs. These investments are further enabled through wartime production unit collaborations, which establish scalable, coordinated partnerships across government and industry to rapidly transition to surge production and meet national defense requirements.

Office of Strategic Capital (OSC): The OSC serves as the DoW’s internal investment bank and uses three tools to revitalize the industrial base underpinning the U.S. national defense: 1) its lending authorities; 2) its advisory services and role as the lead coordinator on deals, capital, and transaction structuring across the DoW; and 3) its ability to catalyze and crowd in private capital into critical areas. The $20.0 bi l l i o nin cr e d i t s u b s i d y f u n d s w i l l s u pp or tt h e O S C^{'} s l e n d in g a c t i v i t i es b y p r o v i d in g d e b t f inan c in g f or s t r a t e g i c in v es t m e n t s in co m p ani es an d p r o j ec t s t o b u i l d in d u s t r ia l ba sec a p a c i t y an d c a p abi l i t i es t ha t a r eesse n t ia l t o na t i o na l d e f e n se, a dd r esseco n o mi cc h o k e p o in t s t ha tt h r e a t e nk ey s u ppl y c hain s, an d s u pp or t d e v e l o p m e n t o f cr i t i c a l t ec hn o l o g i es . T h e O S C^{'} s man d a t or y r e q u es tw i l l b e a ppl i e d a g ain s tt h eco l l ec t i v e$ 200.0 billion in lending authority provided by Public Law 119-21, empowering the OSC to utilize that lending authority to provide critical capital to advance the Department’s requirements.

Acquisition Technology Modernization: The Department has allocated $1.9 billion to modernize its acquisition and technological capabilities, aiming to create a more responsive and efficient Warfighting Acquisition System. This funding will support key programs such as the Acquisition Transformation Support programs and the Nuclear Command, Control, and Communications (NC3) enterprise. Additionally, the funds will be used to provide supply chain risk management tools to at least 50 Major Defense Acquisition Programs by expanding the use of commercially available tools and private sector best practices.

National Security Investment Fund (NSIF): The $1.0 billion for the NSIF offers the most robust and mission-effective structure to implement the President’s vision as outlined in Executive Order 14196, A Plan for Establishing a United States Sovereign Wealth Fund. The fund will invest in and generate returns from foundational, often times dual-use technologies, that have long development cycles but also offer substantial long-term economic and national security benefits such as: defense industrial capacity; critical minerals; strategic assets and supply chains; energy generation; storage and transport; advanced manufacturing and scaled reshoring of technology; global communications; equipment and infrastructure; global logistics and access infrastructure supporting basing and overflight; artificial intelligence (AI) hardware and quantum computing; and advanced materials. The DoW approach to the NSIF is to request the necessary seed appropriations in FY 2027 and then not require any additional appropriations in the out years. The NSIF is designed to be capitalized by the proceeds from its asset monetization program and the returns generated from its initial investments.

Global Resilience Initiative (GRI): The $896 mi l l i o n f or t h e GR I in c l u d es$ 748 million for supply chain management in the Defense Logistics Agency (DLA) Defense Wide Working Capital Fund and $148 mi l l i o n t os u pp or t D L A^{'} s W a r s t o pp er p r o g r am ($ 143 million in Operation and Maintenance and $5 million in Procurement funds). The GRI mitigates the risk forward-deployed U.S. forces currently face in the early stages of a conflict until the industrial base can transition to a wartime production rate and operations tempo. The GRI ensures the Combatant Commands and Services have what they need during an increase in requirements until industry can meet an increased production requirement (surge). The Warstopper program decreases the time required to transition from lower to higher production levels with targeted investments aimed at preserving industrial capability to reduce risk. Together, the Warstopper and GRI funds address these crucial warfighter needs.

Joint Energetics Transition Office (JETO): The $500 million for the JETO will be used for systems engineering and the rapid, full-scale prototyping of weapons systems with new energetic materials. The funding will also expedite the maturation and validation of advanced modeling and simulation tools and modernize test and evaluation activities to improve the quality of future qualification work.

Economic Defense Unit (EDU): At the center of these investments is the EDU. The $189 million supports fully resourcing the organization that will serve as the central nervous system for the DoW’s economic statecraft. The EDU’s mission is to orchestrate a unified strategy by bringing together all of the Department’s economic authorities and tools to defend against adversary actions and proactively build national economic power. The EDU acts as the strategic hub, identifying threats and vulnerabilities and then deploying the precise tool needed for the situation. It integrates the department’s capabilities, ensuring that defensive actions are synchronized with offensive, nation-building investments.

EDU Strategy Table:

Integrated Tool: Equity and Direct Investment
Originating Office / Authority: NSIF, DPA Investments, IBAS
Function Within EDU Strategy: Deploys patient capital to take ownership stakes, fund new factories, and build resilient domestic industries from the ground up. This is the primary “build and own” function.

Section 2: Homeland Defense and Golden Dome for America

Funds in this section focus on continued development of game-changing missile defense sensors, interceptors, and kinetic and non-kinetic capabilities that are necessary to defend the U.S. against ballistic, hypersonic, advanced cruise missiles, and other next-generation aerial attacks from peer, near-peer, and rogue adversaries.

Program Funding:

Golden Dome for America (GDA): $17, 528 mi l l i o n T o t a l H o m e l an d D e f e n se an d G o l d e n D o m e f or A m er i c a :$ 17,528 million

Description: Funding in this section supports the specific capabilities directed in the President’s Golden Dome Executive Order 14186, The Iron Dome for America, including: • Accelerating the Hypersonic and Ballistic Tracking Space Sensor (HBTSS) layer; • Developing and deploying a proliferated layer of Space-Based Interceptors; • Fielding robust underlayer and terminal-phase intercept capabilities; • Developing and deploying non-kinetic tools to augment missile defeat; • Integrating all sensing and interceptor layers into a unified command and control system; • Conducting rigorous, realistic testing and evaluation of all system components; • Ensuring interoperability with key allied missile defense systems; and • Establishing a secure and resilient supply chain for all critical components.

Golden Dome for America (GDA): These initiatives directly align with the 2026 National Defense Strategy mandate to build a resilient defense against growing missile threats. The FY 2027 request of $17,121 million for the Golden Dome for America Fund appropriation will create irreversible momentum for the GDA program, solidify the program’s foundation, and lock in progress on these complex, long-lead time efforts, ensuring the delivery of a credible deterrent and a secure defense for the U.S. homeland.

Homeland Defense Facilities: In addition to the direct GDA program requirements above, the FY 2027 request includes the associated $217 mi l l i o nin D e f e n se - W i d e M i l i t a r y C o n s t r u c t i o n f u n d in g r e q u i r e d t o b u i l d a l o n g - r an g e, e a r l y - d e t ec t i o n, o v er - t h e - h or i z o n r a d a r f a c i l i t y a s p a r t o f a p r o j ec t f u n d e d in co nj u n c t i o n w i t h t h e U .

Submarine Industrial Base Contract Incentives: The $1,440 million supports the Nuclear Shipbuilder Productivity Enhancements (NSPE), a direct investment in the nuclear shipbuilders General Dynamics Electric Boat (EB) and Huntington Ingalls Industries Newport News Shipbuilding (NNS). The EB and NNS are structured such that each shipyard produces specific components of each Virginia Class Submarine (VCS), which are then assembled. The Submarine Capacity and Long-Term Enhancement (SCALE) initiative will increase capacity and promote contracting competition by duplicating capabilities such that each shipyard is capable of independently producing most VCS components. This funding represents the FY 2027 increment in a multi-year investment that will be addressed in future President’s Budgets.

T-AH(X) Hospital Ships: The $650 million supports the purchase of one T-AH(X) Hospital Ship that will begin to replace current hospital ships USNS Comfort and USNS Mercy. An additional T-AH(X) ship is expected to be procured in a future President’s Budget.

Submarine Maritime Industrial Base (SIB): In addition to the FY 2027 discretionary request, the $206 mi l l i o n s u pp or t s in v es t m e n t s in t h e S I B t o p r o m o t e f a c i l i t i es in v es t m e n t an d v e n d or q u a l i f i c a t i o n t o im p r o v e in d u s t r ia l c a p a c i t y an d r e d u ceco n s t r u c t i o n sc h e d u l er i s k t o a c hi e v e a "1 + 2" p r o d u c t i o n c a d e n ce f or C o l u mbia C l a ss S u bma r in es an d V i r g inia C l a ss S u bma r in es .

Maritime Firepower: The $105 million request supports the procurement of 13 Standard Missiles.

Medium Uncrewed Surface Vessels (MUSV): The $50 million request supports the procurement of one vessel.

Section 4: Munitions

Funds in this section focus primarily on addressing critical munitions requirements identified by the Munitions Acceleration Council (MAC). These include 12 legacy munitions that are foundational to U.S. military operations and two emerging capabilities that represent advancements in technology and operational effectiveness. These investments are vital to ensuring the Department’s ability to meet immediate and long-term munitions demands, replenish depleted stockpiles, support the operational needs of U.S. forces, allies, and partners, reestablish deterrence, and meet long-term demand. This ensures the U.S. maintains a credible deterrence posture by increasing munitions availability and readiness while supporting sustained operations for U.S. forces, allied nations, and partner countries in the face of evolving global threats.

To achieve these objectives, the Department has negotiated framework agreements with key vendors that are designed to secure favorable unit costs by locking in pricing through long-term agreements. These agreements ensure cost efficiency while maintaining production stability, enable predictable production rates by providing vendors with the assurance needed to scale production, and invest in infrastructure. The Department is employing innovative acquisition strategies to expand and accelerate industrial base capacity. These include contracting mechanisms that combine government funding with private capital to modernize and expand production facilities, incentivizing private sector investment while ensuring the government benefits from faster delivery schedules and reduced unit costs. Private investments are being directed toward upgrading existing facilities, building new production lines to meet increased demand, improving production efficiency, reducing lead times, and enhancing quality control.
