Defense Budget Tailwinds

DoD FYDP projections show sustained budget growth. That spending flows down through prime contractors to the subcontractor tier where PE operates.

The Department of Defense Future Years Defense Program (FYDP) projects spending across a five-year window. Current projections show sustained growth in key categories: modernization (next-generation platforms, AI/ML integration, space capabilities), readiness (maintenance, training, logistics), and procurement (production of systems already in development). These aren't theoretical allocations. They're congressional authorizations that flow through prime contractor supply chains to the subcontractor tier.

The spending pattern matters more than the topline number. DoD is shifting dollars from legacy platforms to emerging capabilities. Unmanned systems. Hypersonics. Space-based assets. Cybersecurity and information warfare. Electronic warfare and signals intelligence. Each of these spending categories creates demand for specialized subcontractors that prime contractors can't (or don't want to) build internally.

Prime contractor supply chain consolidation accelerates this dynamic. Lockheed Martin, Raytheon (now RTX), Northrop Grumman, and Boeing are actively managing their supply bases. They're qualifying fewer suppliers, demanding higher reliability, and paying premiums for critical capabilities. A small defense subcontractor with a sole-source position on a major program has pricing power that PE investors value.

Foreign military sales (FMS) add another growth vector. The Defense Security Cooperation Agency reported record FMS activity driven by allied nations increasing defense spending in response to geopolitical instability. FMS creates demand for U.S. defense manufacturers and service providers across the supply chain. DSCA notifications (published publicly) reveal upcoming foreign sales that create revenue opportunities for domestic suppliers.

Sub-Verticals: Subsystems to Space

Defense components, MRO, government IT, cybersecurity, space technology, and unmanned systems each offer distinct deal dynamics and growth profiles.

Defense subsystems and components represent the largest PE deal pool in A&D. Circuit boards for radar systems. Precision machined parts for missile guidance. Specialized connectors for military communications. Ruggedized electronics for harsh environments. These are small, highly specialized manufacturers with deep engineering capabilities and narrow customer sets. Arcline's acquisition of Kaman and TJC's purchase of L3Harris Commercial Aviation Solutions illustrate the PE appetite for component and subsystem businesses. FPDS contract data reveals revenue concentration, program exposure, and contract types (firm-fixed-price vs. cost-plus, which affects margin predictability) for every federal contractor.

Maintenance, repair, and overhaul (MRO) is a steady-state business tied to the installed fleet. Military aircraft, naval vessels, ground vehicles, and electronic systems all require ongoing maintenance. MRO contracts are often multi-year with options, providing revenue visibility. The defense MRO market is particularly attractive because aging platforms require more maintenance as they stay in service longer than originally planned.

Government IT and cybersecurity have converged. The DoD's digital modernization strategy, zero-trust architecture mandates, and cyber hygiene requirements create sustained demand for IT services firms with security clearances. PE-backed platforms in government IT are rolling up cleared IT services companies to build scale that wins larger contract vehicles. The cleared workforce is the competitive moat.

Space and satellite technology moved from speculative to investable. Commercial space, military space (Space Force acquisitions), and satellite-based communications/ISR create deal flow across hardware manufacturers, ground station operators, and space-adjacent software companies.

Unmanned systems (drones, autonomous vehicles, robotic systems) represent the growth edge. DoD's Replicator initiative and emphasis on autonomous capabilities drive demand for small unmanned system manufacturers, autonomy software developers, and counter-UAS technology providers.

Data Sources for A&D Origination

FPDS contract data, SAM.gov registrations, DSCA foreign military sales notifications, and DTIC program databases reveal the defense subcontractor universe.

The Federal Procurement Data System is the cornerstone of defense deal origination. FPDS contains every federal contract action, including contractor name, contract value, contracting agency, product/service code, place of performance, and contract type. DoD reported over 89 million contract actions with obligations exceeding $445 billion in FY2024. Mining FPDS data reveals which companies hold defense contracts, how large those contracts are, which programs they support, and whether they're growing or declining. For PE buyers, FPDS essentially discloses the revenue composition of every defense contractor in the country.

SAM.gov (System for Award Management) is the federal contractor registration system. Every company that does business with the federal government must be registered in SAM. The database contains company size standards, NAICS classifications, socioeconomic certifications (8(a), HUBZone, SDVOSB, WOSB), and capabilities statements. SAM data identifies the full universe of defense-eligible companies, including those that have registered but haven't yet won significant contracts. That's your emerging-capability target set.

DSCA foreign military sales notifications provide advance intelligence on international defense spending that creates domestic contractor demand. Each notification identifies the purchasing country, the weapon system or service, and the estimated value. PE buyers can trace FMS demand to supply chain participants.

DTIC (Defense Technical Information Center) houses defense research reports, program documentation, and technology descriptions. While much of DTIC is controlled access, the public portion reveals technology development programs that will become procurement programs. For PE investors focused on defense technology, DTIC data maps the technology-to-production pipeline.

Aviation Week's defense programs database and DoD budget justification documents (J-books) provide program-level spending detail that FPDS doesn't. Matching program spending trends to contractor exposure gives PE buyers a forward-looking view of revenue sustainability for any target.

Security Clearance and CFIUS Considerations

Foreign ownership restrictions, FOCI mitigation, and security clearance requirements create unique deal structuring challenges that are also genuine competitive moats.

Aerospace and defense PE has a complexity layer that no other sector has: national security regulation. This isn't just a compliance checkbox. It's a structural feature that shapes deal origination, valuation, and fund strategy.

The Committee on Foreign Investment in the United States (CFIUS) reviews transactions that could give foreign persons control of U.S. businesses with national security implications. For PE funds with foreign LPs (which is most PE funds), CFIUS review is a real concern. Fund structures must be designed to ensure that foreign LPs don't have control rights, access to classified information, or influence over portfolio company operations. Some defense targets refuse to sell to funds with any foreign LP exposure. That constrains the buyer universe, which is actually an advantage for domestic-only funds.

Foreign Ownership, Control, or Influence (FOCI) mitigation is the DCSA (Defense Counterintelligence and Security Agency) framework for managing cleared contractors with foreign involvement. Mitigation agreements range from Board Resolutions (least restrictive) to Special Security Agreements (SSAs) and Proxy Agreements (most restrictive). The mitigation structure affects governance, board composition, and operational independence. PE buyers must understand FOCI before submitting an LOI on a cleared target.

Security clearances themselves are a competitive moat. A cleared facility with a Secret or Top Secret Facility Clearance Level (FCL) can bid on and perform classified contracts. Getting a new facility clearance takes 12-18 months. Maintaining one requires ongoing compliance. For PE, acquiring a company with existing clearances is dramatically faster than building cleared capabilities from scratch. That makes cleared companies more valuable, and the clearance itself is a quantifiable intangible asset.

We factor CFIUS and FOCI into origination from day one. A target with heavy classified revenue and a fund with significant foreign LP exposure isn't a deal worth pursuing. Understanding that before spending six months on diligence saves real money.

Origination in Aerospace & Defense

Most A&D targets are small defense subcontractors below $50M revenue. FPDS contract data reveals their revenue composition, program exposure, and growth trajectory.

The A&D origination challenge is that the best targets are invisible. A $30M defense electronics manufacturer in Huntsville, Alabama, that derives 80% of revenue from a single missile defense program doesn't have a website worth looking at. It doesn't attend industry conferences. Its CEO doesn't have a LinkedIn profile. But its FPDS contract history shows 7 years of growing revenue on a program with funding through FY2031. That's a PE target.

We build A&D target universes from FPDS contract data, SAM.gov registrations, and corporate ownership records. FPDS gives us revenue composition and program exposure. SAM gives us size, capabilities, and certifications. State corporate filings give us ownership and age data for succession analysis.

The program concentration question is critical in A&D. A company with 90% of revenue from one DoD program carries concentration risk that affects valuation. A company with revenue across 5+ programs and both defense and commercial customers is more resilient. FPDS data lets us calculate program concentration before we ever contact the company. That pre-qualification saves time for everyone.

Defense industrial base mapping is the other origination approach. Starting from prime contractor supply chain requirements (published in subcontracting plans) and working backward to identify qualified suppliers. Then cross-referencing with FPDS to identify which suppliers are actually performing and which programs they serve. That supply-chain-down approach surfaces companies that top-down database searches miss entirely.
