Golden Dome cannot focus solely on exo-atmospheric and midcourse threats. A resilient homeland defense architecture also requires a coherent low-altitude layer capable of detecting, tracking, and responding to cruise missiles and unmanned aerial systems (UAS) that fly beneath traditional radar coverage. These threats exploit dense urban terrain, critical infrastructure corridors, and complex airspace environments where sensing is harder, clutter is higher, and decision timelines are shorter.
While Parallax/OAI is not building interceptors, our deep experience in beyond-visual-line-of-sight (BVLOS) operations, advanced air mobility (AAM) integration, and multi-UAS command and control (C2) positions us to strengthen this layer’s sensing, deconfliction, and operator workflows—making the kill web more responsive from the ground up.
Airborne Sensing That Extends the Defensive Picture
Golden Dome benefits enormously from moving sensors off fixed sites and into the air. Parallax’s Vigilant Spirit system can command and control long-endurance UAS equipped with surveillance radars and payloads that augment both ground-based and space-based sensors. Airborne sensing increases survivability, expands detection coverage, and provides earlier track custody on low-altitude threats.
Civil/Military Deconfliction in Complex Airspace
Dense airspace—especially around cities, ports, bases, and energy corridors—requires operators to maintain awareness of commercial traffic, AAM platforms, and other cooperative aircraft. Parallax has integrated Automatic Dependent Surveillance–Broadcast (ADS-B) ingestion and airspace tools directly into Vigilant Spirit.
“We bring ADS-B into Vigilant Spirit so a UAS operator can see civil traffic and interact safely with everything else in the sky,” said Dr. Dave Gross, Director of Unmanned Systems Research
This gives operators the situational awareness needed to safely maneuver UAS during surveillance, cueing, or response missions—without adding risk to the national airspace system.
From Cooperative to Non-Cooperative Targets
Many low-altitude threats will not broadcast ADS-B or open telemetry. Some will use encrypted links. Others may emit only minimal RF signatures. Attempting to hijack or spoof hostile C2 links is increasingly impractical.
“Early C2 protocols were open and easily hijacked. Today, most links are encrypted… Realistically, you need sensors that pick up non-cooperative targets and display those tracks to the operator,” said Gross.
This is why Parallax emphasizes external sensing modalities, radar cueing, RF detection, and operator workflows that highlight probable non-cooperative targets early.
A Realistic and Safe Range Strategy
Ohio’s SkyVision range has demonstrated the ability to safely fuse FAA radar with test-range telemetry for BVLOS operations. But certain types of testing—particularly destructive intercept scenarios—must occur on DoD ranges.
“You can prototype pieces in Ohio, but anything that hits the ground needs to be at a DoD test range with restricted airspace,” said Gross.
Parallax’s strategy is clear: Prototype workflows, C2, and deconfliction logic in Ohio; validate the lethal components at national ranges.
What This Looks Like in Practice
A modern low-altitude defense cell—enhanced by Parallax’s tools and expertise—operates as an agile, distributed detection and cueing network:
Mobile UAS sensors extend coverage over cities, ports, bases, and critical infrastructure.
ADS-B + local radar fusion provides real-time civil/military deconfliction and ensures operator safety.
Non-cooperative target detection is flagged through external RF and radar cueing.
Multi-vehicle control allows a single operator to scale UAS assets without expanding crew size.
Fused tracks are pushed up to the national picture for custody, handoff, and engagement by C-UAS/SHORAD or higher-tier systems.
This approach strengthens both the local defensive posture and the broader kill web.
“Non-cooperative targets demand external sensing and smart workflows—encrypted links mean takeover isn’t a strategy you can count on,” said Gross. “Prototype the workflow in Ohio; do the destructive, restricted-airspace pieces at national ranges.”
Enabling a Stronger Low-Altitude Layer for Golden Dome
Parallax/OAI’s role is not to replace interceptors or build new sensors—we provide the integration layer that makes low-altitude defense effective and interoperable:
BVLOS expertise to extend sensing where fixed sites cannot reach
ADS-B integration and airspace awareness for safety and deconfliction
Multi-UAS C2 to scale operations affordably
Workflow design and operator tooling that reduces cognitive load
Data fusion pipelines that improve handoff to C-UAS/SHORAD systems
Proven test infrastructure to accelerate development and reduce risk
By delivering these enabling capabilities, Parallax/OAI strengthens Golden Dome’s ability to detect, track, and respond to low-altitude threats before they become catastrophic.
Golden Dome will only be as resilient as its lowest tier—and Parallax ensures that tier is integrated, scalable, and ready.
