Hardware & Software You'll Actually Buy or Build

Nobody starts an infrared search and track business by fabricating focal-plane arrays from scratch. Every viable entrant — from a two-person engineering shop to a 40-person systems integrator — builds around commercially available detector cores and adds the value in packaging, tracking software, and integration. Your business plan should name the specific line items a buyer, lender, or SBIR reviewer expects to see costed out.

• Infrared detector core / focal-plane array: cooled MWIR (mid-wave infrared) for long-range detection, or uncooled microbolometer for lower-cost, maintenance-free perimeter units
• Optics train: germanium or chalcogenide-glass lenses, athermalised housings so focus doesn't drift with temperature swings
• Gimbal or panoramic rotation stage: pan-tilt for gimballed designs, or a continuously rotating head for 360-degree panoramic coverage
• Detection & tracking software: either licensed from an established vendor or built in-house on top of an open computer-vision stack, tuned for small, low-contrast thermal targets against sky or sea clutter
• Ruggedised enclosure: IP66/IP67-rated housing rated for the vibration, shock, and thermal-cycling profile of the target platform (vehicle, mast, vessel, aircraft pod)
• Environmental test access: a vibration table, thermal chamber, and salt-fog or humidity chamber — owned, or contracted from a third-party test house — to run MIL-STD-810 qualification before you can credibly bid
• Systems integration bench: power supplies, video/data interface hardware (Ethernet, MIL-STD-1553, or CAN depending on platform), and a demonstration rig you can bring to a customer site

The single biggest planning mistake at this stage is scoping for a fighter-jet-grade cooled system when the realistic first customer is a port authority or a border-security integrator who needs a panoramic, uncooled unit at a fraction of the cost and complexity. Decide which tier you're building for before you price the lab.

It's also worth deciding early whether you own the environmental test chamber or rent time from a third-party test house. Owning a vibration table and thermal chamber outright makes sense once you're running qualification cycles every quarter, but for a first product it's usually cheaper and faster to contract MIL-STD-810 testing from an established test house — several UK and US labs offer this as a standalone service, and a third-party test report also carries more credibility with a first-time customer than an in-house one. Build the decision into your capital plan rather than defaulting to "buy everything" because it feels more substantial on a funding pitch.

What It Costs to Get an IRST Business Off the Ground

Starting an infrared search and track systems business typically requires $150,000 to $750,000 (£120,000 to £600,000) before your first paid delivery, depending on whether you're targeting perimeter-security/maritime customers directly or positioning as a subcontractor to a prime integrator. That range is wider than most business-plan templates because the two paths carry very different lab, testing, and compliance overhead.

Cost Breakdown

• Optical test bench, lab space & environmental chamber access: $40K–$180K (£32K–£145K)
• ITAR/EAR registration and export-compliance programme build-out: $35K–$60K (£28K–£48K)
• COTS infrared detector cores & focal-plane arrays: $25K–$150K (£20K–£120K)
• Prototype fabrication & MIL-STD-810 environmental/vibration testing: $20K–$120K (£16K–£95K)
• Detection & tracking software development or licensing: $15K–$100K (£12K–£80K)
• Working capital buffer for net-60/net-90 government payment cycles: $30K–$150K (£24K–£120K)

Funding Routes

In the US, SBIR/STTR awards are the most relevant non-dilutive route for a sensor startup: Army, Navy, and DARPA Phase I awards typically provide around $250,000 over roughly six months, with Phase II continuation funding around $1.8M over 24–36 months — enough to fund the lab build-out and a working prototype without giving up equity. Most small manufacturers remain eligible for an SBA 7(a) loan to cover equipment and working capital; the standard exclusions target categories like gambling and passive real estate, not defense electronics manufacturing generally, though lenders will want to see export-control registration already in motion.

In the UK, an Innovate UK Smart Grant is the closest equivalent to SBIR for early-stage sensor development, commonly blended with a Start Up Loan (up to £25,000 at 6% fixed) and private angel capital to cover the export-licensing and testing costs that grants rarely fund in full.

The cost range above splits cleanly by business model. A company positioning purely as a subcontractor supplying sensor cores or software into an existing prime-contractor programme can often launch nearer the $150,000 (£120,000) end, since the prime typically owns integration, environmental qualification, and end-customer certification. A company selling a complete, branded panoramic turret directly to port authorities or infrastructure operators needs to own the full qualification and support burden itself, which is what pushes budgets toward the $750,000 (£600,000) end — largely driven by environmental testing, export-licensing overhead, and the working-capital buffer needed to carry a first direct-sale contract through delivery and payment.

The Supplier Landscape: Where the Components Actually Come From

A credible plan names real suppliers, not generic "component vendors." Reviewers — whether a bank, an SBIR programme manager, or an angel investor who has seen defense-tech pitches before — read a named, sourced bill of materials as evidence you've actually scoped the build, not just the market opportunity slide. It also shortens your own procurement timeline: knowing which two or three suppliers can meet your lead-time and export-classification requirements before you finalise a design saves months compared with discovering a component is unavailable to your target market after you've already committed to a bill of materials.

• Teledyne FLIR OEM: commercial and export-cleared thermal cores, widely used as the starting point for counter-drone and perimeter systems rather than fully custom detector development
• Leonardo DRS: higher-end cooled infrared detector modules for platforms requiring longer detection range
• Lynred (formerly Sofradir) and Xenics: European cooled and uncooled detector suppliers, relevant if you need to keep the bill of materials EU/UK-sourced for a given export-control pathway
• Edmund Optics: germanium and chalcogenide optical components for the lens train
• HGH Systemes Infrarouges: the reference point for panoramic IRST design (their Spynel line) and for licensable detection-and-tracking software rather than building tracking algorithms from a blank page

At the systems level, the competitive set splits cleanly in two. Lockheed Martin, Leonardo, Thales, Northrop Grumman and Aselsan build IRST for fighter aircraft and warships — a market a new entrant realistically cannot compete in directly, and shouldn't try to. Below that tier, HGH, Teledyne FLIR, Chess Dynamics and Controp supply panoramic and gimballed IRST for perimeter security, counter-drone detection and maritime protection — a market with 6–12 month sales cycles instead of 5–10 year defense-acquisition timelines, and one where a well-run small integrator can genuinely win against the primes on responsiveness and price. Anduril's recent unveiling of a lower-cost IRST for aircraft platforms is worth watching too — it signals that even the airborne segment is starting to open up to smaller, faster entrants rather than staying locked to legacy primes.

If your business is closer to industrial or medical thermal imaging than defense search-and-track — inspection cameras, building diagnostics, or clinical thermography — see our related guide to starting an infrared thermal imaging systems business, which covers a different regulatory and customer path.

On the test and certification side, independent labs such as Element Materials Technology and Intertek run MIL-STD-810 environmental qualification programmes on a contract basis across the UK and US, which is usually the fastest route to a certified test report if you don't yet own an in-house environmental chamber. Building the relationship with a third-party test house early — before you have a finished prototype — also shortens the qualification calendar considerably, since good labs book out months in advance during defense-budget cycles.

Who Actually Buys This, and How

A business plan that says "the customer is the defense industry" won't survive a first read from a lender or an SBIR reviewer. Buyers in this market fall into three distinct groups, each with a different sales motion, budget cycle, and decision-maker.

• Prime contractors as channel, not end customer: Lockheed Martin, Leonardo, Thales and Northrop Grumman rarely buy a finished IRST turret from a startup — they buy sub-assemblies, detector modules, or tracking-software licences against a specific programme requirement, usually found through a formal subcontractor RFP or an existing relationship built at a trade show
• Government and quasi-government end users: port authorities, coast guards, border-security agencies, and critical-infrastructure operators (airports, power stations, data centres) buy complete, ready-to-install systems, usually through a public tender or a systems-integrator partner who bundles your sensor with their command-and-control software
• Commercial critical-infrastructure operators: increasingly, ports, offshore energy operators, and large logistics sites are buying perimeter IRST directly for asset protection and safety, outside any formal defense-procurement process, which is often the fastest sales cycle available to a new entrant

In practice, most successful small entrants win their first contract through one of two channels: a subcontract RFP response to a prime that already holds a programme (fastest way to get a credible reference customer), or a direct tender response to a port authority or infrastructure operator (fastest way to get cash in the door without prime-contractor margin stacking). Defense trade shows — DSEI and Farnborough International Airshow in the UK, SOF Week and AUSA in the US — remain the highest-density venue for both routes, and a credible business plan should budget for at least one or two of these events in year one, since cold outbound rarely works in this buyer segment.

The buying trigger is rarely "we'd like an IRST system" in the abstract — it's a specific incident (a drone incursion, a perimeter breach, a lost-tender review after losing a contract to a better-equipped competitor) or a specific compliance deadline (a new port-security regulation, a NATO interoperability requirement). Your go-to-market plan should identify which trigger you're selling against for each segment, because it changes both the messaging and the procurement timeline you should forecast.

Pricing conversations also play out differently across the three buyer groups. Prime contractors negotiate hard on unit price but are comparatively relaxed about payment terms once a subcontract is signed, because their own government payment schedule is predictable. Government end users tend to fix the budget before the tender is even published, so the negotiation is really about scope and delivery timeline rather than price. Commercial infrastructure operators are the most price-sensitive of the three but also the fastest to sign, since they aren't bound by public-procurement timelines — which is exactly why many small entrants use this segment to generate their first reference customer and cash flow before pursuing a slower government tender.

Export Control & Licensing: The Gate You Can't Skip

Unlike most business-plan templates on this site, licensing here isn't a background-check-and-insurance checklist — it's the single largest gating item standing between you and your first sale, because IRST hardware and the software that drives it are export-controlled almost everywhere.

United States

• ITAR registration with the DDTC (U.S. Department of State) — around $2,250, renewed annually; a realistic first-year compliance build-out (gap assessment, written policy, staff training, technical controls) commonly totals close to $35,000
• Export licences (e.g. DSP-5) for each international transfer — typically 60–90 days to process, and shipment cannot occur before approval
• EAR licensing through the Bureau of Industry and Security for any dual-use components not on the U.S. Munitions List — per-license fees generally $150–$5,000
• Facility Security Clearance through the Defense Counterintelligence and Security Agency for classified DoD work — no direct government fee, but it must be sponsored by a prime or government customer and typically takes 6–18 months
• State business licence and standard product/general liability insurance

Founders coming from an engineering background often assume ITAR registration is a paperwork step they can handle themselves in a weekend. In practice, the technical-controls piece — access restrictions on your CAD files, your test data, and any foreign national employees or contractors — takes longer to implement correctly than the registration itself, and getting it wrong is the single most common reason a first DDTC compliance review runs long. Budget the full $35,000 first-year figure and the 60–90 day licence-processing window into your fundraising runway, not just the $2,250 registration fee.

United Kingdom

• Standard Individual Export Licence (SIEL) from the Export Control Joint Unit — no direct ECJU application fee; routine applications typically clear in a few weeks, but thermal-imaging and IRST hardware is commonly referred for interdepartmental review, which can take several months
• List X facility clearance for classified MOD contract work — sponsor-dependent, several months to obtain
• Companies House registration and standard employer/public liability insurance
• Compliance with the Defence and Security Public Contracts Regulations 2011 if bidding directly into MOD procurements

The ECJU doesn't charge for a SIEL, which surprises founders who assume export licensing is a fee-driven bottleneck — the real cost is time, not money. Because military-grade infrared hardware sits squarely inside the interdepartmental-referral category, a UK founder should treat the SIEL timeline as a critical-path item on the sales forecast, not an administrative afterthought that happens in parallel with delivery.

European Union & Wider Export Control

Regulation (EU) 2021/821 requires an export authorisation for dual-use items — including most infrared sensors and surveillance components — shipped outside the EU. The control list implements Wassenaar Arrangement categories, so classifying your hardware against Annex I is a required first step before you can legally quote a non-UK, non-US customer. Businesses selling into the Gulf, Asia-Pacific or Latin America should budget classification and licensing time into every sales cycle, not just the first one — it doesn't get faster with repeat customers unless you move to an open licence.

A practical sequencing note that rarely appears in generic business-plan guidance: classification and licensing should start the moment a serious sales conversation opens, not once a purchase order is signed. Founders who wait until contract signature to start the export-licensing clock routinely lose 2–4 months of runway they'd already promised to an investor or a lender.

How an IRST Supplier Actually Makes Money

Revenue in this business comes from a mix of direct end-user sales, subcontracted hardware supply into prime-contractor programmes, and — increasingly — software and algorithm licensing that carries a much better margin than the hardware itself.

Panoramic IRST turrets sold directly into perimeter-security, port-protection and maritime-surveillance contracts typically price at $90,000 to $220,000 per unit, depending on detection range and resolution. Subcontracted sensor payloads sold into a prime-contractor programme are usually priced per statement-of-work rather than per unit, and carry longer payment terms in exchange for larger, multi-year order books.

Gross margins run 20–35% on hardware-heavy delivery and 60–80% on detection-and-tracking software licensing — which is why several established suppliers, HGH among them, treat their tracking software as a separate, high-margin product line rather than something bundled invisibly into the hardware price.

Worked example: a subcontractor delivering 8 export-cleared IRST turrets a year to two prime integrators at an average contract value of $145,000 per unit generates roughly $1.16M in annual revenue. At a 30% blended gross margin, that's about $348,000 in gross profit. After programme management, business-development travel, export-compliance overhead, and a 15–18% R&D reinvestment allocation (standard for a sensor company that needs to keep its detection algorithm competitive), net margin typically lands between 12% and 18% at this stage of the business.

The businesses that outperform this benchmark are the ones that convert a hardware sale into a recurring software-maintenance or detection-algorithm-licensing contract — turning a one-off capital sale into an annuity revenue stream that smooths out the lumpiness of government and prime-contractor order books.

Contract structure matters as much as headline price. Fixed-price contracts (the norm for direct sales to a port authority or infrastructure operator) put all the delivery-cost risk on you, which is manageable once you've qualified your bill of materials but dangerous on a first-of-kind build where component lead times can slip. Cost-reimbursement and time-and-materials structures, more common on prime-contractor subcontracts and SBIR-funded development work, shift that risk back toward the customer but usually come with tighter reporting and audit requirements. A small number of government buyers will offer an IDIQ (indefinite delivery/indefinite quantity) vehicle once you've delivered a first unit successfully — worth negotiating for specifically, since it converts a one-off win into a standing order book without a fresh tender each time.

The IRST Market in 2026: Size, Growth, Buyers

The global infrared search and track systems market was valued at $7.80 billion in 2025, rising to an estimated $8.32 billion in 2026, a 6.9% year-on-year increase, according to Data Bridge Market Research. A separate estimate from Credence Research puts 2024 market size at $6.70 billion, growing to $9.68 billion by 2032 — different methodologies, but the same broad direction: mid-single-digit-to-high-single-digit annual growth through the decade.

The airborne segment (fighter aircraft and UAVs) currently holds the largest revenue share, driven by long-range threat-detection requirements against low-observable ("stealth") aircraft — IRST is passive, so it can track an aircraft's heat signature without emitting anything a target's radar-warning receiver could detect. The naval segment is forecast to grow fastest through the rest of the decade as navies replace legacy hull-mounted electro-optics with 360-degree panoramic IRST for self-defense against sea-skimming missiles and small-boat threats.

The scale of the fighter-jet segment can be misleading for a new entrant: a $500 million programme value tells you the total addressable market is real, not that a startup can win a slice of it in year one. The realistic entry points are perimeter security, counter-drone detection, and maritime/port protection, where budgets are smaller, procurement cycles are measured in months rather than years, and the buyer is often a port authority, a critical-infrastructure operator, or a mid-sized integrator rather than a national defense ministry.

Regionally, North America holds the largest share of current spend, driven by U.S. Department of Defense modernisation budgets and a steady cadence of Army, Navy and Air Force sensor-upgrade programmes. Europe is growing on the back of NATO interoperability requirements and post-2022 defense-budget increases across the UK, France, Germany and Poland, with naval self-protection refits a particular driver. Asia-Pacific is forecast to grow fastest over the medium term as China, India, Japan and South Korea all expand indigenous and imported IRST capability for both airborne and naval platforms, though export-control restrictions mean a Western small business is more likely to sell into this region through a licensed partner than directly.

Two structural growth drivers show up consistently across the market reports: the proliferation of low-cost drones has pushed counter-UAS budgets — and therefore IRST demand — into police forces, prisons, stadiums and airports that never previously bought military-grade sensors, and the retirement of legacy radar-only perimeter systems is creating a wave of replacement demand as operators add a passive infrared layer alongside radar rather than relying on radar alone. The main restraint is the one this page spends the most time on: export-control complexity slows time-to-revenue for every new entrant, regardless of how good the underlying sensor technology is.

Common First-Year Mistakes

We've reviewed enough defense-electronics business plans to see the same five mistakes recur, almost always with the same consequence: a fundable idea that runs out of runway before it reaches its first paid delivery. None of these are technology problems — every one of them is a sequencing or planning problem, which means every one of them is fixable before you spend a pound or a dollar building the wrong thing in the wrong order.

• Treating export-control registration as a formality. ITAR and SIEL work is a 6-12 month compliance build-out that gates your first export sale, not a form you file the week before shipping.
• Building custom detectors before proving demand. Nearly every viable small entrant integrates COTS focal-plane-array cores from established suppliers rather than fabricating detectors in-house; custom sensor development is a Series A problem, not a pre-seed one.
• Pricing government work without costing the payment terms. Net-60 and net-90 are standard on government and prime-contractor invoices; a founder who prices to a cash-in-30-days assumption will run out of working capital mid-delivery on their first real contract.
• Bidding classified work without a clearance sponsor lined up. Facility Security Clearance and List X sponsorship must come from a prime or government customer before the process can even start — chase the sponsor relationship before the tender, not after you've won it.
• Aiming at fighter-jet-scale programmes from day one. The perimeter-security, counter-drone and maritime segments have 6-12 month sales cycles against 5-10 year defense-acquisition timelines for airborne primes — pick the market you can actually close in year one.

Quick Revenue & Margin Calculator

Use this to sanity-check your own unit economics before you build a full financial model. It uses the same structure as the worked example above — units delivered per year, average contract value, and blended gross margin — so you can see how sensitive net revenue is to each assumption. Try dropping units delivered to 4 (a realistic Year 1 figure) and margin to 22% (typical while you're still qualifying suppliers and absorbing first-article testing costs) to see how much runway a slower first year actually requires — it's usually the gap between those two scenarios that determines whether a founder needs £120,000 or £400,000 to reach a stable second year.
