Editor’s Brief¹

Last week I covered DroneSec, a software-first threat intelligence company. Section 353 of the FY2025 NDAA called for a “Counter Unmanned Aerial System Threat Library” within 180 days of enactment. The FY2026 NDAA pushes that deadline to June 30, 2027. If you know someone working in the Office of the Under Secretary of Defense for Acquisition and Sustainment, now might be a good time to send them last week’s article…

This Week: We’re back to hardware, profiling Echodyne and its metamaterials radars. Never heard of metamaterials? Head to Tech Radar for the quick explainer.

Signal Brief: Echodyne – Metamaterials Radar Redefines Counter-UAS Economics

Echodyne is developing a new class of radar using metamaterials, bringing electronically scanned array (ESA) performance in smaller, more deployable formats. Their proprietary Metamaterials Electronically Scanned Array (MESA) architecture uses standard circuit board fabrication, avoiding costly military-grade components, and can be fielded where traditional radars are too large, power-hungry, or expensive.

Origins & Vision

Founded in 2014 as a spin-out from Intellectual Ventures, Echodyne builds on metamaterials research developed with Duke University and UC San Diego. CEO Eben Frankenberg and CTO Dr. Tom Driscoll aimed to rethink radar by replacing traditional phased array hardware with structured materials that manipulate electromagnetic waves.

Early prototypes tested through the DHS Silicon Valley Innovation Program quickly moved from pilot to procurement, leading to early wins such as a $20M IDIQ with CBP and inclusion in the U.S. Army’s $191M Security Surveillance System (SSS) program.

Today, Echodyne designs dual-use radars for defense, national security, border security, airspace management, and advanced air mobility.  Their focus: make radar small, affordable, and practical for real-world deployment, especially in places where traditional sensors are hard to justify.

Key Takeaways

• Performance at Lower Cost – ESA-level accuracy and multi-target tracking in man-portable form factors.

• Built for Field Deployment – Radars can be mounted on tripods, vehicles, or towers without specialized support equipment and operates in fixed, portable, temporary, and on-the-move (OTM) modalities

• Commercially Manufacturable – Uses standard PCB processes, avoiding defense-only supply chain bottlenecks.

• Export-Friendly – Commercial status enables faster coalition adoption without licensing delays.

Tech Radar:

EchoGuard – Ultra-low SWaP, Short-range Radar

1.4 kg sensor for short-range detection of drones, humans, and vehicles. Already deployed for Army base security and DHS border surveillance, often as modular kits augmenting tower-based sensors.

Key Capabilities

• Detects drones at 1.5 km, humans at 2,250 m, vehicles at 3,500 m

• 120° azimuth × 80° elevation FoV

• Tracks up to 20 simultaneous targets with real-time classification

• Man-portable with tripod or vehicle mounting

• TCP/IP integration and weatherproof, all-climate performance

EchoShield – Low SWaP, Medium-range, Multi-mission Radar

Software-defined radar for base perimeters, convoy security, mobile SHORAD, and high-priority sites.

Key Capabilities

• Detects Group 3 UAS at up to 12 km

• Sub-0.5° accuracy, 130° azimuth × 90° elevation coverage

• Tracks 1,000 targets with classification

• Adaptive/Cognitive waveform scheduling

• Integrates with C2 systems and remote weapon stations

Market Signals

Funding & Growth

• Total Funding: $202M across six rounds

• Latest Round: $136M Series C (June ‘22)

• Notable Investors: Bill Gates, Baillie Gifford, Northrop Grumman, NEA, Madrona, Vanedge, Lux

• Valuation: $528M

Echodyne’s design breaks the cost and SWaP barriers that have limited AESA deployment, enabling radar coverage for missions and units previously priced out. This opens the market well beyond traditional defense primes, particularly for dispersed and coalition operations

Contracts & Government Traction

• U.S. Army SSS Program – $191M IDIQ via ATSC; 46 units delivered with growth potential.

• DHS CBP Contract – $20M IDIQ; 30+ units deployed for land and maritime border security.

• Northrop Grumman Partnership – Strategic investment and integration into mobile C-UAS solutions.

Looking Ahead

The counter-UAS fight didn’t blindside us. The Army saw it coming thirty years ago, when analysts warned that lethal drones, reconnaissance UAVs, and low-flying cruise missiles would challenge forward-deployed forces and fixed sites.

In response, the Army began modernizing short-range air defense (SHORAD), only to begin divesting programs in 1999-2000 in favor of “general-purpose” capabilities. Two decades later, the National Commission on the Future of the Army called that draw down a “modernization shortfall,” and ISIS drones proved the warning right.

Today, DoD calls unmanned systems an “urgent and enduring threat” to U.S. personnel, facilities, and assets. The Army’s Joint Counter-Small UAS Office sets doctrine, requirements, and training, yet other services have been slow to match that commitment. That structure may soon change.

The current draft of the FY2026 National Defense Authorization Act would dissolve the Army-led office within 60 days of enactment, shifting its functions, assets, and civilian workforce to the Office of the Under Secretary of Defense for Acquisition and Sustainment.

Regardless of who is in charge, the operational consensus is well understood.  Layered defense demands high-end sensors like LTAMDS and SPY-6, paired with commercial low-SWaP radars such as EchoShield and EchoGuard for the short range fight. Combined with kinetic and non-kinetic interceptors and fielded in distributed networks, Echodyne can create multiple engagement points that are far harder to saturate.

The window to act is short. In the Indo-Pacific, vast distances and dispersed islands mean each unit must land with its own counter-UAS suite on day one. The fastest path forward is to field interoperable, off-the-shelf kits now, refine them in training and operations, and out-iterate adversaries before they adapt.

We’ve had the forecast for three decades. The rain is here. It’s time to start using our umbrellas instead of arguing about what color they should be.

Challenges

• Production Scaling – Meeting surge demand without sacrificing quality or affordability.

• Spectrum Competition – Operating effectively in congested or contested electromagnetic environments.

• Technology Evolution – Staying ahead of emerging low-cost ESA radar designs from competitors.

Bottom Line:

The counter-UAS problem is a structural vulnerability across the force. Low, slow, small drones have slipped past traditional air defense and delivered decisive effects.

Even with proven systems, pushing enough sensors forward, tying them into C2, and training units outside the air-defense MOS to use them is difficult. Congressional language in the FY 2026 NDAA shows growing impatience: slow tech transition, weak integration at brigade-and-below, and uneven service buy-in.

Echodyne is one of the few companies with scalable radars already under contract with both the Army and DHS. Stop waiting for perfection. Field what works, now.
