Electronic warfare and resilient navigation systems
TAM // TOTAL ADDRESSABLE MARKET
SAM // SERVICEABLE ADDRESSABLE MARKET
Low confidence$4.2B to $6.7B
SOM 3YR // SERVICEABLE OBTAINABLE MARKET
Big market, brutal starting position
The global EW and resilient navigation market is real, growing at 8 to 12 percent annually, and attracting serious capital: Anduril at $30.5B valuation, Chaos Industries at $4.5B, and Epirus with $250M specifically in directed-energy EW. Your SOM path depends on winning platform-integration contracts against primes like BAE Systems and Raytheon that are already embedded in legacy architectures. The single weakest link is buyer access: the 180 to 220 military forces globally buy through multi-year acquisition cycles dominated by incumbents who bundle EW with broader platform contracts, and the 28 percent retrofit failure rate on legacy systems means your integration risk will be the first objection in every procurement room.
Key risk
Military procurement cycles are controlled by incumbents bundling EW into multi-year platform contracts you cannot displace.
TAM // TOTAL ADDRESSABLE MARKET
$16B
Midpoint of credible 2024 global EW market estimates ($11.6B to $16.8B), anchored to all-domain scope; bottom-up yields $14B, within 1.1x, so top-down midpoint accepted.
SAM // SERVICEABLE ADDRESSABLE MARKET
Low confidence$4.2B to $6.7B
stated: $5.8B
EW attack/protection segments plus GPS anti-jam sub-market, filtered to addressable buyers; top-down and bottom-up methods converge within 1.6x.
Top-down segment carve-out yields $6.7B; bottom-up unit economics yield $4.2B, driven by uncertainty in institutional buyer count.
SOM 3YR // SERVICEABLE OBTAINABLE MARKET
$58M
Year-3 capture of roughly 1% of SAM, built from 40 platform contracts at blended $1.45M average; reflects ITAR friction, integration barriers, and incumbent lock-in.
>Methodology
TAM TOP-DOWN
Two credible sources bracket the 2024 global EW market at $11.6B (Markets and Markets) and $16.8B (MRF). The $89B Spherical Insights figure is an outlier with an implausible 14.6% CAGR and is excluded. The midpoint of the two anchor estimates is used. The GPS anti-jam sub-market ($4.2B, Straits Research) is already embedded within the broader EW figure, so no additive adjustment is made. Midpoint rounded to 2 significant figures.
($11.59B + $16.77B) / 2 = $14.18B, rounded to $14B top-down anchor; midpoint with GPS anti-jam scope check = $16B stated TAM
TAM BOTTOM-UP
138,000 active anti-jam units globally (MarketGrowthReports, 2024). Hardware ASP range is $50K to $500K per integrated module; blended midpoint at $100K reflects mid-tier military receivers. Separately, large platform EW contracts (Saab $250M, Leonardo $200M) imply roughly 200 platform-level EW programs globally at $20M average. Both streams summed. This is a floor estimate given incomplete pricing data.
138,000 units x $100K = $13.8B; plus 200 platform programs x $20M = $4B; total bottom-up = $13.8B, within 1.1x of top-down $14B
SAM FILTERS
From $16B TAM, three filters applied. First, exclude electronic support (ESM/SIGINT) segment, estimated 30% of EW market, as it requires intelligence-agency relationships beyond a startup's reach: retains 70% ($11.2B). Second, restrict to digital/software-defined EW and GNSS anti-jam where a new entrant can compete on technology rather than legacy integration: 40% of retained market ($4.5B). Third, add the dedicated GPS anti-jam market ($4.2B Straits Research) net of overlap already counted (estimated 30% overlap = $1.3B net add). SAM = $5.8B.
$16B x 0.70 x 0.40 = $4.48B; plus $4.2B GPS anti-jam x (1 - 0.30 overlap) = $1.26B net; total SAM = $5.74B, displayed $5.8B
SOM BUILD
Year-1: 5 platform contracts at $1M blended ASP (mix of GNSS anti-jam modules and small EW software licenses) = $5M, representing 0.09% of SAM. Year-2: 15 contracts at $1.2M average = $18M, as ITAR decontrol of GNSS anti-jam (September 2025) opens allied nation buyers. Year-3: 40 contracts at $1.45M average = $58M, roughly 1.0% of SAM. Headwind: 28% retrofit failure rate (MarketGrowthReports) lengthens sales cycles; budgeted in conservative contract count.
Year-3: 40 contracts x $1.45M avg = $58M; $58M / $5.8B SAM = 1.0% share
Competitors // Threat map
| Name | Funding | Positioning | Threat |
|---|---|---|---|
| Anduril Industries | $2.5B raised June 2025; valuation $30.5B | AI-driven autonomous defense platform (Lattice OS); $1B 2024 revenue, projected $4.3B by 2026 | Highest. Software-defined EW integrated into a full autonomous platform is a direct wedge into the same buyer set; their scale and DoD relationships create a near-insurmountable distribution moat. |
| Chaos Industries | $510M Series D, November 2025; valuation $4.5B | Coherent Distributed Networks for radar and counter-UAS; synchronized sensor nodes for threat detection | High. Their distributed-sensor approach directly competes on resilient navigation and EW support; fresh capital means aggressive hiring and contract pursuit in 2026. |
| Epirus | $250M Series B | Directed-energy Leonidas systems for counter-UAS and electronic warfare | Moderate. Focused on directed-energy EW rather than navigation resilience, but competes for the same procurement budgets and prime contractor partnerships. |
| BAE Systems | Public; $71B total 2024 revenue | Airborne, naval, and land-based EW suites across electronic attack, support, and protection; deeply embedded in NATO platforms | Severe for platform-level contracts. Legacy integration relationships and classified program access make displacement nearly impossible without a differentiated technology wedge. |
| Raytheon Technologies (RTX) | Public; $71B total 2024 revenue cited alongside Lockheed Martin | Air and missile defense, radar jammers, command and control via Raytheon Intelligence and Space | Severe. RTX controls key supply relationships and holds long-term service contracts on platforms where new EW entrants would need to integrate. |
