The Degaussing Market in 2026

A degaussing system reduces a warship's DC magnetic signature so that magnetic-influence mines and sensors struggle to detect it. In practice that means coils of heavy cable routed through the hull, a control system that varies the current in those coils as the vessel changes heading and latitude, and the power supply that feeds them. It is a small, technical, defence-gated market, and that is exactly why a well-built plan wins funding here: the buyers are few, the barriers are real, and a founder who can show a credible route to a first contract stands out.

The global degaussing systems market was worth about $0.87 billion in 2025 and is forecast to reach roughly $1.20 billion by 2031 at a compound annual growth rate near 5.45%, according to Mordor Intelligence, 2025. That growth is not driven by consumer demand; it is driven by naval modernisation budgets, a resurgence of magnetic-influence sea mines in contested waters, and a wave of retrofit programmes on ageing surface vessels. A separate estimate from Fortune Business Insights, 2025 places the near-term value in a similar band and attributes expansion to the same modernisation cycle.

Geographically, North America holds about 35.65% of the market on the back of US Navy shipbuilding, while Asia-Pacific is the fastest-growing region at roughly 8.12% a year as India, South Korea, Japan and Australia expand and indigenise their fleets. Europe grows more steadily inside NATO procurement frameworks. For a new entrant this matters because your addressable market is a function of which navies and shipyards you can realistically supply once export controls are accounted for.

Two structural facts should shape your whole plan. First, submarines lead demand at about a 30.67% revenue share, but mine countermeasure vessels are the fastest-growing vessel class at around 7.65% a year, which is where smaller specialists often find the door open. Second, retrofit work makes up more than half of all installations and is growing faster than new-build. A firm that positions around retrofit shipsets and calibration services can start earning without needing to win a place on a new-construction programme, which typically takes years to enter.

It also helps to understand why the money is flowing now. Magnetic-influence sea mines are cheap, hard to clear, and effective, which makes signature reduction a live concern rather than a legacy line item. Naval budgets in the US, the UK, and across the Indo-Pacific have shifted toward survivability and mine countermeasures, and every new frigate, corvette, submarine, and unmanned platform carries a degaussing requirement. On top of new demand, decades of existing hulls need their ageing coils and control systems refreshed. For a founder, the practical takeaway is that demand is durable and programme-driven, not cyclical consumer spend, so a plan can credibly forecast multi-year revenue once the first relationship is in place.

In the UK specifically, the sector sits inside a defence-industrial base that actively wants more capable small and medium suppliers. The Ministry of Defence has repeatedly signalled it wants to widen its supplier pool and reduce reliance on a handful of primes, and naval signature management is precisely the kind of specialist capability where a focused SME can earn a durable niche. That policy backdrop is worth stating in your plan, because it frames a small degaussing firm as filling a stated national need rather than chasing a crowded commercial market.

Defence Funding & SBA Data

Financing a degaussing venture rarely looks like a coffee-shop loan. The capital is lumpy, the customers are governments, and the equipment and compliance costs land before the first invoice clears. Here is how the realistic funding routes break down on each side of the Atlantic.

United States

The SBA 7(a) loan is the workhorse for small defence manufacturers, offering up to $5 million with terms up to 25 years for real estate and 10 years for equipment and working capital. Manufacturing NAICS codes (a degaussing-coil assembler would typically sit under 335 or 336 series electrical-equipment and defence-related manufacturing) see steady 7(a) approval activity, and lenders such as Live Oak Bank, Newtek and Byline Bank actively underwrite specialist manufacturers. Because degaussing hardware is defence-related, most 7(a) lenders will want to see a signed subcontract or a credible letter of intent from a shipyard or prime before advancing on equipment.

Beyond debt, the SBIR and STTR programmes run by the Department of Defense fund non-dilutive R&D in phases: Phase I awards commonly run $75,000 to $250,000 and Phase II can reach $1 million to $1.7 million. Superconducting and adaptive-control degaussing is an active topic area, which is precisely how established players got there. American Superconductor, for example, won a $14.94 million contract from the Naval Surface Warfare Center to deliver a high-temperature superconducting degaussing shipset, and ran a live test aboard the USS Higgins (AMSC investor release, 2024). Your plan does not need a nine-figure story; it needs to show the same funding ladder used at a startup scale.

United Kingdom

In the UK, the Start Up Loans scheme provides up to £25,000 per founder at 6% fixed with free mentoring, useful for the earliest pre-revenue phase. Beyond that, defence-specific funding is the real story: the Defence and Security Accelerator (DASA) runs themed competitions, and Innovate UK grants support magnetics and materials R&D. SEIS and EIS remain the most efficient equity route for a UK founder, giving early investors 50% (SEIS) or 30% (EIS) income-tax relief, which materially de-risks the first raise for a hardware business with a long path to revenue.

Whichever route you pursue, funders in this niche read the plan for one thing above all: evidence you can actually reach a buyer. A five-year forecast with a named prime, a realistic first shipset value, and a compliance timeline beats any amount of market-size prose.

What It Costs to Launch

Starting a degaussing system business typically requires $220,000 to $1.4 million in the US, or roughly £170,000 to £1.1 million in the UK. The spread is wide because the model you choose changes everything: a pure calibration and ranging service starts near the bottom of that band, while a firm that winds its own coils, builds control electronics and qualifies them to military standards sits near the top.

Cost Breakdown

• ITAR/export registration, CMMC Level 2 cyber, facility security: $25K–$120K (£20K–£95K)
• Magnetics test & coil-winding equipment (fluxgate magnetometers, Helmholtz coils, winding rigs): $80K–$450K (£62K–£350K)
• Controlled workshop / clean-assembly lease and fit-out: $40K–$260K (£30K–£200K)
• First qualified electrical / magnetics engineers: $45K–$320K (£35K–£250K)
• Prototype build + MIL-STD-810 / MIL-STD-461 qualification testing: $20K–$150K (£15K–£115K)
• Working capital across long defence payment cycles: $60K–$400K (£47K–£310K)

The line that founders most often under-budget is working capital. Defence receivables commonly run 60 to 120 days and are tied to milestones, so you can be profitable on paper and still short of cash mid-programme. A defensible plan carries at least six months of operating runway and models the gap between milestone acceptance and payment, not just the headline contract value. The second most under-budgeted line is compliance: treat ITAR registration, CMMC and qualification testing as capital items with their own timeline, because a lapsed control or a failed qualification test can stall a whole contract.

A useful discipline is to build the budget three ways: a lean service-only launch, a mid-tier assembly-and-service model, and a full design-and-build operation. The lean version leans on a magnetic range and calibration instruments, keeps hardware inventory near zero, and can reach a first invoice fastest; it is the lowest-risk way to prove the business before committing to a winding line. The mid-tier version adds coil and cable assembly, which raises equipment and material spend but opens up shipset revenue. The full version adds control-electronics design and formal qualification, the highest capital and the highest ceiling. Showing all three in the plan lets a funder see you have chosen deliberately rather than defaulted to the most expensive path, and it gives you a staged growth story: start lean, reinvest contract cash into assembly, then into design, as references accumulate.

Suppliers, Primes & the Value Chain

Almost nobody enters this market by selling a finished degaussing system directly to a navy on day one. The realistic entry point is as a sub-tier supplier or service provider to the shipyards and primes that already hold the programmes. Knowing who sits where in the chain is half the strategy, so map it in your plan before you write a single financial line.

System primes and OEMs to know

• L3Harris Technologies (US): supplies MPES degaussing control systems that feed independent coils through the hull
• American Superconductor / AMSC (US): pioneered high-temperature superconducting degaussing, tested aboard USS Higgins
• Exail (France): magnetic-signature reduction systems trusted by more than 70 navies and armies
• Ultra Electronics / Ultra Maritime (UK): degaussing and broader signature-management products for surface and sub-surface platforms
• Wärtsilä (Finland) and ESCO Technologies (US): integrated marine and defence electronics suppliers
• Larsen & Toubro (India): customised degaussing solutions under "Make in India" indigenisation rules
• Polyamp AB (Sweden): power and control sub-systems used in signature-management builds

Where does a new firm fit? Three viable positions repeat across successful entrants. You can be a coil and cable-assembly supplier, winding and terminating the shipset harnesses that a prime integrates. You can be a calibration, ranging and de-perming service provider, taking measurement equipment to the dockside or a magnetic range to characterise and tune a vessel's signature. Or you can be a software and analytics vendor, building the adaptive-control or signature-prediction models that are the single fastest-growing part of the market at about 7.87% a year. The equipment side (coils and cabling) is a larger 33.45% of spend but grows slower, so your choice is a genuine trade between volume and margin.

For the physical side, your own supply chain will include high-purity copper conductor and specialist cable, mu-metal and soft-magnetic shielding material, ruggedised power electronics, and fluxgate or SQUID magnetometers for test. Name your two or three candidate suppliers for each in the plan; buyers and investors both read that as operational seriousness rather than a paper concept.

Revenue Streams & Margins

Degaussing revenue is a blend of one-off hardware sales, recurring services, and, increasingly, software. A realistic small-firm price sheet looks like this: coil-and-cable shipsets run $150,000 to $2 million per hull depending on vessel size; active-control electronics run $200,000 to $1.5 million; calibration and ranging service days bill at $3,000 to $12,000 per day; and software or analytics licences run $40,000 to $180,000 per year. Larger retrofit programmes are bundled and can reach $500,000 to $8 million across a class of vessels.

Net margins across the sector typically fall between 12% and 28%. Hardware sits at the lower end because material and qualification costs are heavy; services and software sit at the upper end because they scale on people and code rather than copper. That is the strategic argument for pairing a hardware entry with a recurring-service or licence tail: it lifts blended margin and smooths the lumpiness of programme-based revenue.

The plan should model each stream separately, because they have different working-capital profiles. Hardware ties up cash in materials months before delivery; service revenue is close to cash-neutral; software is cash-positive on renewal. Investors want to see you understand that, not just a single top-line growth curve.

One more revenue lever is worth building into the plan: the through-life relationship. A degaussing system installed today needs periodic re-ranging, recalibration, and eventually a control-electronics refresh as components age or the threat evolves. A firm that sells a shipset and then holds the maintenance and re-ranging contract for that class of vessel converts a one-off sale into a decade of predictable service revenue. That annuity is exactly what lifts a hardware business from a lumpy project shop into something an investor can value on recurring cash flow, and it is the strategic reason to prioritise service quality on the very first delivery.

Export Control & Compliance

This is the section most generic guides skip and the one that decides whether your business is even legal to operate. Degaussing hardware and its technical data are defence-controlled in every major market. Get the sequence right and it becomes a moat; get it wrong and you cannot ship, hire foreign nationals, or even email a drawing.

United States

• ITAR registration + USML compliance: naval degaussing typically falls on the United States Munitions List, so you register with the Directorate of Defense Trade Controls (DDTC) at the Department of State - about $3,000 a year, roughly 45–60 days
• CMMC Level 2 cybersecurity certification: required to hold controlled unclassified information on DoD contracts; $25K–$100K and 6–12 months via a certified assessor
• SAM.gov registration + CAGE code: free but mandatory to bid on federal work; allow 2–4 weeks
• Deemed-export controls on staff: sharing controlled technical data with a foreign national on US soil counts as an export, so build access controls into your operations plan

United Kingdom

• Export licences from the Export Control Joint Unit (ECJU): controlled magnetics and signature technology need a Standard Individual or Open licence; typically 20–40 working days
• DE&S supplier onboarding + JOSCAR/Hellios registration: the practical gateway to MOD and shipyard subcontracts; £800–£3K and 1–3 months
• Cyber Essentials Plus: required for MOD contracts handling identifiable data; £1.5K–£6K and 4–8 weeks
• DEFSTAN conformance: UK Defence Standards govern how equipment is specified and qualified for naval use

NATO, Europe & other markets

To bid on NATO tenders you will need an NCAGE code, and your products must align with the relevant NATO STANAG agreements on magnetic signature and amagnetic tooling - STANAG 2897, for instance, caps explosive-ordnance-disposal tools at a 5 nanotesla signature, a reminder of how tight the tolerances in this field are. In India, the "Make in India" framework imposes indigenous-content thresholds that shape whether a foreign supplier can participate directly or must partner with a local prime such as Larsen & Toubro. Your plan should state clearly which jurisdictions you will serve first and why, because that decision, more than any other, sizes your realistic market.

Mistakes That Sink First Bids

Across defence-hardware plans we have reviewed, the same avoidable errors show up. Each one is easy to fix on paper and expensive to discover after launch.

• Selling to the wrong customer. Pitching a finished system to a navy when the real, winnable path is sub-tier supply to a shipyard or prime. Model the subcontract route first.
• Treating compliance as admin. ITAR, CMMC and qualification testing are capital lines with timelines. Leaving them out of the budget understates both cost and time to first revenue.
• Assuming fast payment. Defence receivables run 60–120 days on milestones. A plan without a working-capital cushion looks naive to any experienced funder.
• Ignoring the retrofit segment. Retrofit is more than half of all installs and easier to enter than new-build, yet founders chase the harder new-construction programmes for prestige.
• No named route to a first contract. A plan with no identified shipyard, prime or programme reads as a science project. One credible letter of intent changes the entire risk picture.

Who Actually Buys, and How They Buy

The degaussing customer base is narrow and slow-moving, which is a feature rather than a bug: once you are inside a shipyard's approved-supplier list, competitors cannot casually displace you. Your plan should name the segments precisely rather than describing a vague "defence market".

The primary customers are national navies and coastguards, who set the requirement but rarely buy components directly. Next are the shipyards and defence primes that hold the construction and refit contracts and issue the subcontracts a new firm can realistically win. A third and often overlooked group is operators of specialist vessels: mine countermeasure ships, hydrographic and research vessels, and increasingly unmanned surface and sub-surface platforms whose small magnetic signature is a core design requirement. That unmanned-vessel demand is one of the reasons the software and adaptive-control segment is growing fastest.

The buying cycle is long and gated. A typical path runs: requirement definition by the navy, a tender or framework issued by the shipyard or procurement body, a supplier qualification stage where your export posture, certifications and test data are scrutinised, then a bid, then milestone-based delivery over months or years. Nothing about it is fast, and a plan that assumes a 30-day sales cycle signals inexperience. A stronger plan shows how you shorten the qualification stage - by completing DE&S or SAM.gov onboarding early, by holding qualification test evidence ready, and by leaning on a named prime relationship that vouches for you.

Where to start, realistically

Most viable first orders are not for a whole ship's system. They are for a coil harness, a batch of cable assemblies, a calibration campaign, or a software module inside someone else's system. That is the wedge. Land one, deliver flawlessly, gather the reference, and use it to move up the value chain toward higher-margin control electronics and analytics. The plan's growth curve should mirror that climb, not leap straight to full-system supply.

Operations, Facility & First Hires

Operations in a degaussing firm revolve around three capabilities: winding and terminating coil and cable assemblies to specification, characterising and tuning magnetic signatures with calibrated instruments, and controlling technical data so nothing leaks outside your export authorisation. Each shapes the facility and the team.

The workshop is not a generic unit. Coil-winding and cable-termination benches need clean, controlled space; magnetic measurement demands an area reasonably free of stray fields and ferrous clutter, or access to an external magnetic range for full-ship characterisation. Data control means a segregated network, access logging, and physical separation of controlled drawings - the same discipline CMMC and Cyber Essentials Plus certify. Building the facility around these three needs from the start avoids an expensive retrofit once a contract's security requirements land.

The first hires that matter

• Lead magnetics / electrical engineer: owns coil design, signature analysis and qualification test strategy. This is the hire investors look for first.
• Quality & compliance lead: runs the export-control programme, supplier qualification packs and Defence Standard conformance. Often part-time to start, but never absent.
• Production / assembly technicians: skilled cable and harness build; scale with order book rather than hiring ahead of revenue.
• Business development with a security clearance: the person who can sit in a shipyard's supplier review and be trusted with programme detail.

A defensible plan staffs conservatively in Year 1, treats security clearances and controlled-data training as onboarding costs, and shows headcount rising in step with the contract pipeline rather than ahead of it. Over-hiring before the first milestone is one of the fastest ways a well-funded hardware startup runs out of cash.

Key Terms, Defined

Investors outside defence often stumble on the vocabulary. Defining these plainly in your plan signals command of the field and keeps a non-specialist reader engaged.

• Magnetic signature: the disturbance a vessel creates in the Earth's magnetic field, which mines and sensors can detect. Reducing it is the entire point of degaussing.
• Active degaussing: powered hull coils whose current is varied in real time by a control system to cancel the ship's field as heading and latitude change.
• Passive degaussing / deperming: a one-off application of a strong external field to permanently reduce the hull's residual (permanent) magnetism.
• Coil shipset: the full set of coils, cabling and connectors installed through a hull for one vessel - a common unit of sale for sub-tier suppliers.
• Magnetic range: a measurement facility, often underwater, where a vessel's signature is characterised before and after treatment.
• Fluxgate magnetometer: the workhorse sensor for measuring low-level magnetic fields during calibration and ranging.
• Retrofit programme: installing or upgrading degaussing on an existing vessel during refit - more than half of all installations and a natural first market.
