Business development challenges for defense contractors
Companies entering or expanding in the defense market tend to encounter the same specific obstacles.
- The customer is not one customer. The Department of Defense is a federation of military departments, defense agencies, and combatant commands, each with its own acquisition organizations, program offices, and priorities. "Selling to DoD" is not a strategy; selling to a named program office within a named command is.
- Requirements are set years before they are competed. Defense requirements move through a planning and budgeting process long before a solicitation appears. By the time a requirement is competed, the shape of it has usually been settled for some time.
- Program offices and contracting offices are different customers. The program office owns the requirement and the technical problem. The contracting office runs the acquisition. Engaging one and ignoring the other is one of the most common mistakes new entrants make.
- Past performance gates entry, and subcontracting is the usual route. For most new entrants the realistic first step is subcontracting to a prime rather than winning a prime award. That makes prime relationships a core BD workstream, not a fallback.
- Compliance requirements are a real barrier. Defense work carries obligations beyond standard federal contracting — the DFARS supplement, safeguarding requirements for controlled unclassified information, and in many cases facility or personnel clearances. These affect what you can pursue and need to be understood before, not during, a pursuit.
- The pathways multiply. Beyond standard FAR-based competition there are Other Transaction agreements, consortium-based prototyping, SBIR and STTR, and a wide range of existing contract vehicles. Each has different entry requirements and timelines, and picking the wrong one wastes quarters.
How defense BD differs from general B2B sales
Three structural differences drive almost everything else.
The budget cycle governs the calendar
Defense funding moves through a long planning, programming, budgeting, and execution process, then through annual authorization and appropriations legislation. The practical consequence for business development is that the moment to influence a requirement is when it is being planned and programmed — often a year or more before you would see anything public.
The federal fiscal year ending on 30 September also produces a well-known pattern of increased obligation activity in the final quarter. It is a real feature of the calendar, but treating year-end as a business development strategy rather than an execution reality is a mistake: the requirements being obligated in September were shaped much earlier.
Influence happens through structured, documented channels
Defense acquisition is a regulated process. Contracting officers conduct market research under FAR Part 10, publish sources sought notices and RFIs, hold industry days and advance planning briefings to industry, and document what they learn. These are the legitimate channels, and they are genuinely open — but they are structured, and they close when the solicitation is released.
There is no defense equivalent of persuading a buyer to make an exception. The work is being credible, known, and technically relevant before the requirement is fixed.
Teaming is structural, not opportunistic
Large defense primes operate under subcontracting plans and maintain small business liaison officers as a matter of regulatory obligation, not goodwill. The DoD Office of Small Business Programs and the service-level small business offices exist to route qualified small businesses toward that demand. Understanding this changes teaming from cold outreach into engaging a channel that is designed to be engaged.
Teaming also carries compliance with it. When a prime shares Federal Contract Information or Controlled Unclassified Information with you, the protection requirement follows that information, and many primes now screen suppliers on it. What is CMMC? explains the program, Do I need CMMC? helps you work out whether it applies to you, and our CMMC guides cover the rest.
Identifying relevant DoD customers
Narrowing from "the Department of Defense" to a workable target list is the first substantive piece of defense BD work. It happens in layers.
Layer 1 — component
Army, Navy, Marine Corps, Air Force, Space Force, or a defense agency such as the Defense Logistics Agency, DISA, DARPA, DTRA, MDA, or the Defense Health Agency. Combatant commands, including USSOCOM, buy distinctively and are often overlooked.
Layer 2 — acquisition organization
Below the component sit the organizations that actually award contracts: Army Contracting Command and the Mission and Installation Contracting Command; the Navy's systems commands including NAVSEA, NAVAIR, NAVWAR and NAVFAC; the Air Force Life Cycle Management Center and Space Systems Command; and DLA's supply chain organizations. Each has its own portfolio and its own habits.
Layer 3 — program office and buying office
Program Executive Offices and their subordinate program offices own requirements. The specific contracting office attached to them runs the acquisition. This is the level at which BD actually operates — a target list naming components rather than offices is not yet a target list.
Layer 4 — installation
For services, sustainment, facilities, and logistics work, installation-level contracting offices award a great deal of business that never appears on anyone's list of major programs. They are frequently the most accessible entry point for smaller firms.
Free help exists and is underused
APEX Accelerators, funded through the DoD Office of Small Business Programs, provide no-cost assistance to businesses pursuing defense work, including help understanding buying commands and registration requirements. Whatever else you do, use them.
Understanding historical defense spending
Defense buying history is public, and it is the most reliable evidence available about what a command will buy next. The analysis is more useful when it is done in a deliberate order.
- 1
Establish what is bought under your codes
Explore spending by NAICS codeStart from the NAICS and product or service codes that describe your work, and look at what defense components have actually purchased under them — volume, typical contract size, and which organizations do the buying.
- 2
Identify the buying organizations behind the numbers
Browse federal agency profilesAggregate award data by awarding office rather than by component. A department-level figure tells you very little; a specific contracting office that awards steadily under your codes is a target.
- 3
Examine the awards themselves
Search historical contract awardsLook at individual awards for scope, value, contract type, vehicle, competition status, and set-aside designation. Whether work has historically been set aside for small business tells you a great deal about how you would need to compete for it.
- 4
Map the incumbents
Research contractors and incumbentsIdentify who currently holds the work and what else they hold. Incumbents are competitors on a recompete and potential teaming partners everywhere else — often simultaneously.
- 5
Work out the recompete timing
Period-of-performance data tells you when work comes back to market. Recompete timing is one of the few genuinely predictable things in defense contracting, and it defines how early positioning has to begin — usually a year or more out.
- 6
Cross-check against published forecasts
Defense components publish procurement forecasts and long-range acquisition estimates. Read them alongside the historical data rather than instead of it: forecasts show intent, award history shows behaviour. Where they disagree, behaviour is usually the better guide. Award data is published through USAspending.gov and FPDS.
Finding primes and teaming opportunities
For most companies entering defense work, subcontracting is the realistic first route. It builds relevant past performance, demonstrates you can operate under defense contract terms, and creates the relationships that later support prime bids.
Identify primes by portfolio, not by reputation
The primes worth approaching are the ones holding contracts that create demand for your specific capability, in your target commands. That is an evidence question answerable from award data, not a matter of approaching the largest names.
Use the small business liaison channel properly
Large primes maintain small business liaison officers because their contracts carry subcontracting obligations. Approaching an SBLO with a specific, relevant proposition — naming the contract, the scope element you can support, and the evidence you can do it — works considerably better than a general capability introduction.
Do not overlook mid-tier and small primes
Small business primes on set-aside work also need subcontractors, and the relationship is often faster to build and more consequential to both parties than a slot on a large prime's bench.
Be useful before you are needed
The best time to be added to a bid team is well before the solicitation. Primes assemble teams during capture, on the basis of who they already know can perform. Turning up after release, when the team is set, is the most common wasted effort in defense BD.
Also worth evaluating: SBIR/STTR and Other Transactions
For technology and prototype-stage capabilities, the SBIR and STTR programs and Other Transaction agreements offer non-traditional entry routes into defense work, frequently through consortia rather than open competition. They are not right for every company — services businesses in particular often find them a poor fit — but they are worth deliberately evaluating rather than ignoring.
Building relationships before solicitations
Everything legitimate happens through defined channels. These are the ones that actually matter, roughly in order of how early they open:
- Small business offices and specialists at the component, command, and installation level — the most accessible starting point, and explicitly there to be contacted.
- Advance planning briefings to industry and industry days, where commands describe upcoming requirements before they are competed.
- Sources sought notices and RFIs — a written response is a documented input into the agency's market research and often the single highest-value activity available to a small contractor.
- Capability briefings with program offices, when there is a genuine technical fit to discuss rather than a general introduction to give.
- Prime contractor small business liaison officers, approached with a specific and evidenced proposition.
- Consortium membership, where the relevant work runs through Other Transaction vehicles.
- Professional and industry associations aligned to your target command, which is where a great deal of informal awareness is built.
Stay inside the rules
Once a solicitation is in progress, communication is restricted to the channels the solicitation defines. Procurement integrity rules, organizational conflict of interest provisions, and restrictions on contact with government personnel are real and enforced. Legitimate BD works entirely within them — and anyone offering you an inside track is describing something you should decline.
Building a defense opportunity pipeline
A defense pipeline needs to track things a general federal pipeline does not, because the timelines are longer and the entry routes more varied.
What a defense pipeline should capture
- Component, command, program office, and contracting office — all four, separately
- The acquisition pathway: standard FAR competition, existing vehicle, Other Transaction, SBIR, or subcontract
- Whether you would pursue as prime or sub, and with whom
- Incumbent, current period of performance, and expected recompete window
- Set-aside status and your eligibility for it
- Required compliance posture — clearances, safeguarding requirements, certifications
- The next specific action and its date, which is the field most pipelines quietly leave empty
Stage it by influence, not by paperwork
The most useful staging for defense work reflects how much influence remains available: identified, researched, engaged, qualified, in capture, in proposal, submitted, awarded or lost. Opportunities that reach the proposal stage without having passed through engagement are, in most cases, opportunities you are bidding rather than competing for.
The general federal workflow underneath this — capabilities, codes, award analysis, agencies, offices, incumbents, teaming, qualification, capture — is set out in our guide to how GovCon business development works.
BD vs. capture in defense pursuits
The distinction matters more in defense work than almost anywhere else, because defense capture periods are long and resource-intensive.
Business development is market-facing and continuous: finding where the demand is, becoming known, building relationships, and keeping a qualified pipeline moving. Capture is opportunity-specific and finite: once a particular pursuit is qualified, capture is the work of positioning to win that specific award — competitive assessment, teaming decisions, solution shaping, price-to-win thinking, and win themes.
On significant defense pursuits, capture can begin a year or more before the solicitation and consume substantial effort throughout. A common failure is treating capture as something that begins when the solicitation drops, at which point most of the decisions that determine the outcome have already been made by someone else.
We cover the handoff between the two disciplines, and how capture support can be structured, in the guide to fractional capture management.
When Fractional BD makes sense for a defense contractor
The model tends to fit defense-focused companies when:
- You have a technically credible capability but no map of which commands and program offices would buy it.
- You are established with one component and want to expand into another, where you have no relationships at all.
- Your defense revenue is concentrated in one or two contracts with a recompete approaching.
- You are entirely subcontract-dependent and want to build toward prime capability deliberately.
- Engineering and delivery leadership are doing BD between technical commitments, inconsistently.
- You need someone who already understands defense buying structures rather than someone who will learn them on your budget.
When it does not fit
If your capability has no evidenced defense demand, if you cannot meet the compliance posture your target work requires, or if you lack the delivery capacity to perform, BD support is premature. Those are solvable problems — they are simply different problems, and they should be solved first.
An example 90-day engagement structure
This is an illustrative structure showing how a defense-focused engagement is typically sequenced — not a description of a past client engagement or a prediction of results. Actual plans are built around your capabilities and target market.
- 1
Days 1–30: definition and market evidence
Establish capabilities, past performance, delivery capacity, compliance posture, and any clearance position. Confirm NAICS and PSC alignment. Analyze historical defense award data under those codes to establish whether real demand exists and which organizations generate it. Produce a shortlist of components, commands, program offices, and contracting offices, with evidence behind each.
The deliverable at day 30 is a defensible target list and an honest assessment of viability — including the possibility that the assessment is negative.
- 2
Days 31–60: positioning and channel entry
Sharpen capability positioning for the specific commands identified. Identify the primes whose portfolios create demand for your capability and open small business liaison conversations. Make contact with relevant small business offices. Begin monitoring and responding to sources sought notices and RFIs. Stand up the pipeline with a written qualification standard.
The deliverable at day 60 is an operating pipeline, live teaming conversations, and at least the beginnings of a documented presence in the market research channels.
- 3
Days 61–90: qualification and pursuit rhythm
Qualify what has been identified against the written standard and remove what does not pass. Advance the strongest teaming conversations toward agreements. Begin capture work on any pursuit that genuinely warrants it. Establish the ongoing weekly and monthly cadence.
The deliverable at day 90 is a qualified pipeline, a working rhythm, and a clear-eyed view of which segments justify continued effort and which do not.
What 90 days will not produce
Awards. Defense acquisition timelines make that unrealistic, and any provider structuring a 90-day plan around promised wins is describing something the acquisition process does not permit them to control. What 90 days can produce is a defensible target market, real relationships in motion, and a pipeline you can manage.
