DHS Releases C‑UAS Siting Guide to Support World Cup Host Cities
DHS Field Guidance Aims to Accelerate Counter‑UAS Readiness for Major Events
Federal scientists published a practical primer designed to speed up how local teams choose locations for counter‑UAS sensors—radar, RF detectors and electro‑optical/infrared cameras—before the influx of visitors for the World Cup. The document shifts site selection from ad‑hoc rooftop guesses to methodical surveys that quantify line‑of‑sight, electromagnetic noise and obstruction effects across complex cityscapes.
The administration linked the guide to targeted funding: FEMA committed $250 million that covers 11 host municipalities plus the National Capital Region, creating immediate budgetary capacity for equipment purchases and installation. Agencies are urged to define an Area of Regard (AOR)—a three‑dimensional airspace envelope—to align sensor roles, for example a two‑kilometer radius extending to roughly 1,000 ft AGL in one illustrative scenario.
Practical tradeoffs dominate the advice: increasing antenna height extends detection range but can leave gaps close to the ground; tuning radar to suppress urban clutter reduces maximum reach. RF detectors are presented as more forgiving of partial obstruction but more vulnerable to nearby transmitters, while EO/IR units demand unobstructed panning arcs and illumination planning for night operations.
Planners are told to measure the local electromagnetic noise floor, log access points and document site contacts using included field worksheets so installations can progress rapidly without repeated surveys. The lab that authored the primer also solicits operational feedback from users to iterate the guidance rapidly ahead of the tournament.
Because most matches fall in dense urban cores, the guide emphasizes realistic sensing corridors rather than unrealistic blanket coverage; that focus shortens deployment timelines and concentrates resources on probable threat vectors. It also flags common urban pitfalls—reflections off glass and water, vehicular traffic clutter, and broadcast towers—that can generate false returns or blind spots.
Installation guidance for each technology class includes placement heuristics, obstruction avoidance and environmental hardening recommendations such as housings, wipers and thermal management for cameras. The document frames choices in operational terms so police and first responders can match a sensor mix to mission priorities within constrained procurement windows.
Legal and coordination considerations run alongside technical advice: the guide assumes law enforcement will harmonize local ordinances, spectrum use and interagency access plans during the rapid build‑out. The overall intent is pragmatic—reduce variance between cities so vendors, integrators and operators work from a common playbook under tight timelines.

Global Race for Counter-Drone Funding Accelerates as U.S. Policy Spurs Purchases
Policy clarity and large procurements are pushing counter‑UAS activity from pilots to funded programs while allied reshoring and milestone‑driven investments are reinforcing domestic production and certification priorities. Market winners will be integrators that can prove interoperable, auditable systems and manage supply‑chain, export‑control and testing risks.
European Commission Unveils Continent‑Wide Counter‑UAS Action Plan
The European Commission ordered a coordinated civilian counter‑UAS campaign and a roadmap to tighten drone identification, detection, and cross‑border incident sharing. The plan sets deadlines, proposes a 100 g remote‑ID rule, and links security reforms to industrial growth forecasts of €14.5B by 2030.
Sentrycs Scout portable C-UAS deployed with German state police
Sentrycs has delivered a compact counter-UAS system to a German state police unit and will showcase its man-portable Scout system at Enforce Tac. The solution uses an RF-based protocol manipulation method to detect, identify, and assume control of unauthorized drones without broad-spectrum jamming or GNSS disruption.
Europe Makes Drones and C‑UAS Core to Its Defense Doctrine
At the 62nd Munich Security Conference (Feb 13–15, 2026) EU and NATO-linked policymakers reframed unmanned aerial systems and counter-UAS as central defense capabilities. The Munich Security Report 2026 and leaders’ interventions tied repeated drone incursions and hybrid pressure to urgent needs for airspace sensing, rapid attribution, interoperable procurement, and sustained readiness.
NASA RAM-AO Working Group Advances Autonomous Multi‑Aircraft UAS Integration
NASA’s RAM-AO working group is convening March 3–5 at NASA Ames to develop validation, regulatory, and crew-design frameworks for autonomous multi‑aircraft UAS operations. The effort — led by Aptima and informed by the U.S. Army — targets white papers and V&V tools that could accelerate BVLOS policy and FAA certification pathways.
DIU Seeks Commercial Sensors to Close Small-Drone Detection Blind Spots
The Defense Innovation Unit issued a Commercial Solutions Opening seeking commercially driven, networked sensing systems to detect, track and classify small unmanned aircraft for both fixed installations and maneuver forces, with Phase 2 demonstrations slated for spring 2026. The notice prioritizes mature, producible technologies that can operate in GPS‑denied and contested electromagnetic environments and signals a predictable pathway from demonstration to accelerated production.
Pentagon’s fast-moving laser program raises safety and policy questions after El Paso airspace closure
A Defense Department anti-drone laser lent to Customs and Border Protection prompted a temporary FAA airspace shutdown over El Paso, highlighting how directed-energy systems are moving from experiments into routine use. That operational momentum—backed by multihundred‑million to billion‑dollar buys, allied purchases and reshoring incentives—sharpens the need for certification, airspace integration and supply‑chain resiliency before domestic deployments scale up.
U.S. Defense Boost for Autonomy Carves Open Market for RF Sensing and Training Consolidation
The Pentagon’s proposed standalone autonomy line item and associated prize competitions are accelerating procurement of AI-enabled platforms, privileging resilient perception, low‑latency compute and orchestration software. Concrete commercial moves—ranging from a staged VisionWave–SaverOne RF partnership and FPV airframe and training awards to a $100M round for ground‑vehicle autonomy—illustrate how milestone‑driven transactions and bundled hardware‑plus‑training offers are shortening the pathway from prototype to fielded capability.
