This five-part series walks the full arc of building an aerospace & defense (A&D) government contracting business: entering the market, breaking in as a new supplier, moving from subcontractor to prime, scaling as an established small prime, and building a pipeline you can actually win and perform. It is for general educational and informational purposes only and is not legal, accounting, cybersecurity, export-control, financial, or government-contracting advice. It does not guarantee eligibility, approval, award, or business results. Requirements vary by solicitation, agency, product, data, and contractor circumstances — verify current requirements with the responsible government office and qualified professional advisors before acting. References to programs, policies, funding, and regulations reflect publicly available information as of August 2026 and may change.
Part 1: The Money Is Real. The Barriers Are Too.
The aerospace and defense market is enormous, but its size can create the wrong impression. Seeing billions of dollars in appropriations does not mean a new company can register in SAM.gov, find a solicitation, and immediately compete. The money is real. So are the technical, regulatory, financial, and source-approval gates separating qualified suppliers from everyone else.
For FY2026, Congress provided approximately $839.2 billion for Department of Defense discretionary activities, per the Congressional Research Service's FY2026 Department of Defense Appropriations overview. The department also remains the federal government's dominant contracting buyer — readers can examine obligations through the Department of Defense profile on USAspending.gov.
The opportunity is not evenly distributed. Several investment areas have attracted especially strong attention:
- Missile defense and Golden Dome-related capabilities
- Munitions production and industrial-base capacity
- Shipbuilding, submarines, and unmanned maritime systems
- Space-based sensing, communications, and tracking
- Aircraft sustainment, spares, repair, and modernization
- Cybersecurity, resilient networks, command and control, and mission software
The broader industrial strategy is not simply to purchase more finished platforms. It is also to strengthen fragile supply chains, expand production capacity, add qualified sources, and bring nontraditional companies into defense acquisition, as described in the Department's National Defense Industrial Strategy and its Implementation Plan.
The A&D Difference
Generic government-contracting advice usually starts with registration, certifications, opportunity searches, and proposals. Those steps matter, but aerospace and defense adds several gates that can determine whether a company is eligible to see the data, manufacture the item, handle the information, or receive the award.
Quality systems. AS9100 is widely expected for aerospace manufacturing, with AS9110 for maintenance organizations and AS9120 for distributors. A socioeconomic certification may open a competition, but it does not make an unapproved company capable of supplying flight-critical hardware.
Cybersecurity. Contracts involving Federal Contract Information or Controlled Unclassified Information can trigger FAR, DFARS, NIST SP 800-171, and CMMC requirements, which can also flow down to subcontractors. Because implementation status can change, monitor the official DoD CMMC program site and read the clauses in each solicitation and subcontract.
Export controls. Companies that manufacture, export, broker, or handle defense articles or technical data may face ITAR or EAR obligations. Start with the State Department's Directorate of Defense Trade Controls and obtain qualified legal advice for your facts.
Approved-source restrictions. Many defense spare parts are not open to any manufacturer that can reproduce them. The government may restrict an item to approved sources, require a Source Approval Request, or require First Article Testing before production. The DLA small-business resource center provides SAR, alternate-offer, and related supplier resources.
Supply-chain integrity. Defense contractors may face counterfeit-parts controls, traceability requirements, specialty-metals restrictions, domestic-source rules, and rated-order priorities. For electronic parts, review DFARS 252.246-7007 and the solicitation-specific requirements.
The Practical Lesson
Do not enter A&D by chasing the largest program you can find. Enter through the narrowest credible opening that matches your current qualifications — a specific NSN family, a repair or sustainment niche, one software or cyber mission problem, a subsystem integration specialty, a build-to-print subcontract, or an SBIR/STTR topic aligned to existing intellectual property.
The companies that grow tend to play the stage they are actually in. New entrants establish eligibility and credibility. Subcontractors build relevant performance and systems. Small primes pursue vehicles and repeatable customer access. Each stage has a different strategy.
Part 2: Breaking Into Aerospace & Defense
For a new aerospace and defense supplier, the first objective is not to bid on everything. It is to become visible, eligible, and credible for a tightly defined category of work — and that requires more than completing SAM.gov registration.
Build the Foundation in the Right Sequence
Register in SAM.gov. Obtain a Unique Entity ID and complete the free registration at SAM.gov. Domestic entities generally receive a CAGE code through this process. Make sure the legal name, address, banking, ownership, and taxpayer information match authoritative records; validation problems can delay activation.
Select NAICS and PSC codes deliberately. NAICS codes help determine size eligibility; Product and Service Codes describe what agencies buy. Use USAspending.gov to see how agencies coded comparable awards, and SAM.gov Contract Opportunities to see the language and codes used in live and archived notices.
Complete the SBA small-business profile. Contracting personnel and prime contractors use SBA systems to research potential suppliers — treat the profile as a searchable federal sales page.
Register in DLA DIBBS when appropriate. Manufacturers and distributors pursuing Defense Logistics Agency buys should learn the DLA Internet Bid Board System, which gives suppliers access to many DLA solicitations, awards, technical-data links, and quoting functions.
Obtain JCP certification when controlled technical data is involved. The U.S.–Canada Joint Certification Program allows certified contractors to request access to certain unclassified export-controlled technical data, via the DD Form 2345 process. Certification does not replace export-control compliance or automatically grant access to every file.
Address ITAR, cybersecurity, and quality requirements based on the work you will actually pursue. Compliance should be engineered around the target market — not purchased as a random collection of badges.
First-Revenue Paths That Make Sense
Different companies should use different doors: manufacturers through open-competition DLA parts, lower-complexity items, build-to-print subcontracts, and repeatable NSN families; technology firms through SBIR/STTR, innovation organizations, and targeted subcontracts; commercial product companies through micro-purchases, simplified acquisitions, and resellers; and professional-services firms through prime supplier portals, agency small-business offices, teaming, and set-asides aligned to past performance.
The fastest path is often subcontracting because the prime already owns the customer relationship, vehicle, compliance framework, and program context. That does not mean remaining a subcontractor forever — it means building evidence before assuming prime-level risk.
Read the AMSC Before Pursuing a Part
For DLA parts, the Acquisition Method Suffix Code can tell you whether the government has enough technical data to compete the item or whether source approval is required. AMSC G generally means the government has rights to the data and the item may be acquired competitively; AMSC B, C, or D may involve source control, engineering approval, or approved CAGE/part-number restrictions. Always read the current solicitation and technical requirements — a code is a qualification signal, not a substitute for the procurement documents.
What a Source Approval Request Does
A Source Approval Request is the technical package a prospective supplier submits to be evaluated as an approved source for a restricted item. A strong SAR may require the technical data package and configuration baseline, evidence of rights to use the data, manufacturing and inspection process sheets, quality-system evidence, sub-tier supplier controls, test and qualification data, relevant production history, nonconformance and corrective-action records, and a First Article Testing plan if required. The Engineering Support Activity — not simply the buyer — typically determines technical acceptability; DLA's SAR and alternate-offer resources explain the route for prospective sources.
Source approval can take months and, in difficult cases, longer than a year. That is why a good strategy targets families of recurring parts rather than a single low-demand item.
Certifications Open Doors; Capability Wins Work
An 8(a), HUBZone, SDVOSB, WOSB, or EDWOSB certification can improve access to certain competitions. It cannot replace technical approval, relevant performance, capacity, pricing discipline, or compliance. The right question is not "which certification will get me a contract," but "which certification strengthens a credible offer in the market I am equipped to serve."
Part 3: Subcontractor to Prime
Subcontracting is not a consolation prize. In aerospace and defense, it is often the most intelligent way to enter a program, prove performance, learn the customer, and build the systems needed to prime responsibly. The mistake is treating a subcontract as an isolated sales transaction; the better approach is to use each subcontract to accumulate relevant performance, customer and program knowledge, quality and business-system maturity, and a defensible path to larger workshare or prime responsibility.
Get Onto the Right Supplier Lists
Large primes maintain supplier, sourcing, and small-business programs, but registering in a portal is only the beginning — your profile must match a real requirement, commodity, subsystem, customer, or program. Primes with covered contracts may have small-business subcontracting plans under FAR Part 19, which creates a real incentive to identify capable small suppliers, though compliance credit does not rescue a supplier that cannot perform. APEX Accelerators, agency small-business offices, matchmaking events, and industry associations can help create introductions, but the conversation still needs to be anchored to a real need.
Mentor-Protégé Is a Development Strategy
The SBA Mentor-Protégé Program allows an eligible small business to receive approved assistance from a mentor, and can support a joint venture that receives an exception to affiliation when structured and operated correctly under 13 CFR 125.9. The DoD Mentor-Protégé Program is a separate program focused on strengthening the defense industrial base through developmental assistance. A good agreement is not a logo-sharing exercise — it should close specific gaps in cybersecurity, quality certifications, proposal and capture capability, production planning, accounting systems, facility or security requirements, and customer access.
Teaming Agreement or Joint Venture?
A contractor teaming arrangement under FAR Subpart 9.6 often places one company in the prime role and another in a subcontract role. It is faster and simpler for a specific pursuit, but vague promises about future workshare can cause disputes. A joint venture is the offeror itself, and can allow members to combine capabilities and qualifying experience, but brings additional formation, proposal, performance, reporting, and workshare requirements. For an SBA mentor-protégé JV, the small protégé must perform at least 40% of the work performed by the joint venture partners, and its work must be more than administrative or ministerial — review 13 CFR 125.8 before structuring or bidding through a JV. If the small business is merely passing work through to a large partner, the structure can create affiliation, eligibility, performance, and False Claims Act risk.
Build Past Performance Intentionally
Subcontractors should document more than revenue: scope and complexity, dollar value and period of performance, customer mission supported, on-time delivery and quality metrics, technical outcomes, problems solved, prime program-manager references, and corrective actions and lessons learned. Under current acquisition rules, agencies may consider the experience and past performance of joint-venture members when the JV lacks its own record, and first-tier small-business subcontractors also have mechanisms to request performance assessments in qualifying circumstances.
Do Not Prime Before the Business Can Carry the Contract
Winning the award can be the beginning of the risk. Before pursuing cost-reimbursement or operationally complex prime contracts, assess whether the company has an adequate accounting system, reliable timekeeping and labor distribution, direct and indirect cost segregation, job-cost reporting by contract, estimating discipline, purchasing and property controls, sufficient working capital, contract administration capacity, and a defensible subcontract-management process. The SF 1408 pre-award survey identifies features expected in an acceptable accounting system for certain awards, and larger CAS-covered defense contracts may implicate the business systems described in DFARS 252.242-7005. Graduation should be deliberate: prime when you can manage the cash, compliance, people, schedule, and customer relationship — not merely when a solicitation allows you to bid.
Part 4: Scaling as an Established Small Prime
Once a small business has credible performance, capable systems, and a defined market position, growth becomes less about finding individual solicitations and more about building repeatable access to customers through contract vehicles, innovation pathways, ordering contracts, and program relationships.
Contract Vehicles Are Distribution Channels
A multiple-award contract or governmentwide acquisition contract is not revenue by itself — it is permission to compete within a defined marketplace. Important vehicles include the GSA Multiple Award Schedule, OASIS+ for complex professional services, Alliant 3 for enterprise IT, NASA SEWP for IT products, 8(a) STARS III for qualifying 8(a) IT firms, and service- and agency-specific IDIQs. OASIS+ moved to continuously open solicitations in January 2026, allowing qualified firms to seek entry beyond the initial awards.
The strategic questions are whether your target customers use the vehicle, whether its scope matches the work you actually sell, whether you can meet the qualification and reporting requirements, whether the competitive pool is favorable, and whether you have a task-order pipeline after award. Without customer demand and capture, a vehicle can become an expensive credential.
Learn Fair Opportunity
Task orders under multiple-award contracts are often competed using fair-opportunity procedures under FAR 16.505. These competitions can move faster and demand shorter responses than open-market acquisitions, which creates an advantage for companies with reusable content, current pricing, rapid bid decisions, and deep knowledge of each vehicle's ordering procedures.
Use SBIR/STTR for More Than Phase I
SBIR and STTR are often described as research grants; in defense, the more valuable strategy may be transition. Phase I establishes feasibility, Phase II develops and demonstrates the solution, and Phase III commercializes or transitions the technology using non-SBIR funding. Phase III work derived from prior SBIR/STTR efforts may support a direct award when statutory and agency requirements are met, provided the company can trace the Phase III requirement back to the funded technology. Start with the official DoD SBIR/STTR portal and the SBA SBIR/STTR program overview.
Nontraditional Acquisition Pathways
Other Transaction authority can support research, prototypes, and certain follow-on production. OTs are not FAR procurement contracts, but they are not unregulated or automatic — competition, cost-sharing, nontraditional-participant, successful-prototype, and follow-on conditions can determine the available route; DARPA provides an official Other Transactions training resource. Commercial Solutions Openings allow agencies to solicit innovative commercial products and services using a streamlined process, especially relevant to software, data, cyber, autonomy, and dual-use technology. Companies should also evaluate innovation front doors such as DIU, AFWERX, SpaceWERX, SOFWERX, Army xTech, and DARPA based on the customer, maturity level, and transition sponsor — not simply because a pitch opportunity is open.
Match the Acquisition Pathway to the Customer's Problem
The Adaptive Acquisition Framework includes pathways for urgent capabilities, middle-tier acquisition, major capabilities, software, business systems, and services; the pathway affects documentation, decision speed, funding, test expectations, and the buyer's tolerance for iteration. DAU's Adaptive Acquisition Framework resource is a useful starting point.
Prepare for the Small-Business Cliff
Growth can change eligibility. Revenue, employees, affiliates, joint ventures, acquisitions, and recertification events can affect size status, and a company can reach a point where it is too large for set-asides but lacks the scale of a major prime. Plan before that happens by building unrestricted-market past performance, developing differentiated intellectual property or technical depth, diversifying vehicles and customers, strengthening capture and pricing, evaluating acquisitions and investments for affiliation risk, and developing a mid-tier competitive strategy. The goal is not merely to win more contracts — it is to create repeatable access that survives changes in programs, vehicles, and size status.
Part 5: Build a Pipeline You Can Win — and Perform
The final stage of a mature aerospace and defense strategy is not opportunity discovery. It is disciplined selection. Most companies can find more solicitations than they can responsibly pursue; the advantage comes from identifying requirements early, understanding the incumbent and acquisition path, making hard bid decisions, and protecting the company's ability to perform after award.
Use Different Sources for Different Questions
SAM.gov Contract Opportunities shows what the government is planning, researching, or buying now. USAspending.gov shows who received the prior award, how much was obligated, and when it might recompete. The Federal Procurement Data System shows how the transaction was coded and competed. DoD contract announcements flag major awards and primes that may create subcontracting opportunities, and the GSA Forecast of Contracting Opportunities flags requirements that may emerge before solicitation. Paid intelligence platforms can accelerate research, but no database replaces customer engagement and primary-source validation.
Qualify Before You Write
A practical bid decision should test the customer and acquisition office, the actual problem beneath the statement of work, whether the opportunity is open, set aside, vehicle-restricted, or source-restricted, whether you can perform the critical work yourself or through a credible team, whether the evaluator will view your past performance as relevant, whether you can meet security, quality, data-rights, export, facility, and flow-down requirements, who the incumbent is and what advantage would justify change, whether you can price to win without creating a loss, whether you influenced or understood the requirement before the final RFP, and whether you can finance and administer the work if you win.
Position Narrowly
In A&D, "we do IT," "we manufacture parts," or "we provide engineering" is rarely differentiated. A stronger position sounds like cyber defense for weapon-system enclaves, multi-sensor data fusion for deployable command-and-control environments, reverse engineering and production of a defined family of obsolete aviation components, secure migration of mission data from a named legacy environment, or ruggedized racks and containment for deployable or edge data centers. Narrow positioning makes it easier for government buyers and primes to know when to call you.
Finance the Contract, Not Just the Proposal
Government work can create a cash gap between payroll, material purchases, production milestones, invoicing, and payment. Defense progress-payment policy may provide more favorable rates for qualifying small businesses — review the current contract terms and DFARS 232.501-1. Performance-based payments, advance-payment structures, accelerated subcontractor payments, receivables financing, SBA lending, surety support, and private working capital may also be relevant; the SBA Surety Bond Guarantee Program can help eligible small businesses obtain bonding, and assignment of claims is addressed in FAR Subpart 32.8. Build a 13-week cash forecast before bidding — a profitable contract on paper can still produce a liquidity crisis.
Common Failure Modes
- Chasing every opportunity instead of owning a niche
- Entering after the RFP without customer or competitive knowledge
- Underestimating AS9100, CMMC, ITAR, DCAA, testing, or data-rights costs
- Signing teaming agreements with unclear workshare
- Priming before the company has systems and working capital
- Pricing to win without pricing to perform
- Relying on one vehicle, customer, program, or socioeconomic status
- Ignoring size-standard and affiliation risk
- Treating compliance as a one-time certification instead of an operating discipline
Set Realistic Timelines
Registration can take weeks. Technical qualification or source approval can take months or longer. Building a sustainable defense revenue base commonly takes years. That is not an argument against entering the market — it is an argument for planning the entry correctly: pick a narrow market, complete only the registrations and compliance needed for it, build relevant performance through the most credible first-revenue path, use teaming, mentor-protégé, and vehicles to expand access, invest in systems and working capital before assuming larger risk, and qualify relentlessly, pursuing only work you can win and perform.
The aerospace and defense market rewards patience, specialization, and proof. The companies that last do not simply find contracts — they build the qualifications, relationships, systems, and financial capacity to deliver when the opportunity arrives.
