Per-node sensor capabilities for a 20' ISO container reference design (HoloGrid Sentinel class — 120 kWp PV, 264 kWh battery, 9m telescoping mast, autonomous drone dock). Ranges are conservative estimates from public defense and academic sources. The full sensor electronics stack fits in 1-3 rack units inside the container at ~50-150W continuous draw — <1% of daily PV harvest.
This atlas is a concept demonstration, not a precise range model. Coverage is rendered as uniform circles for visualization. Real-world performance varies significantly with terrain (line-of-sight obstructions, mast height), atmospheric conditions (ducting, rain attenuation, fog), sea state, sea spray, antenna obstruction, target signature (EIRP, RCS, IR signature), and sensor fusion benefits across the network. Treat the displayed envelopes as architectural illustrations of the concept's shape and scale, not as commitments about specific link budgets.
Theater-class active radar (SPY-1/SPY-6, AWACS-class), forward-based X-band (TPY-2), Over-the-Horizon (JORN/Container) and ionospheric sky-wave systems are not deployable at the node footprint and bandwidth this network supports. The strategic regime (≥500 NM) is what the network contributes to via fusion and cueing of higher-tier theater assets, not what any individual node delivers.
The CONOPS argument: uniform deployable hardware, distributed siting strategy. Edge nodes carry the same passive sensor stack as backbone nodes — what differs is geographic position. Far-edge nodes extend the coverage blanket because their footprints don't overlap with anyone else's. The mosaic is what gives the network its theater reach.
Framing in this atlas is anchored to current doctrine. Editions and paragraphs are cited so staff can verify against source.

An interactive atlas of a candidate network of landward distribution nodes (HoloGrid Hubs) and Cross-Domain Contact Layer sensor nodes (HoloGrid Sentinels) positioned across the COFA states, U.S. Pacific territories, and key archipelagic geography — the maritime environment FM 4-0 (20 March 2026, ¶6-3) cites by example with "the Marshall Islands in the South Pacific."
Doctrine assumes a persistent shore-side reception, staging, and onward-movement node exists at the landward end of the Army watercraft delivery chain (JP 4-01.6; FM 4-0 ¶6-6; ATP 4-13) — but does not say who builds or mans it in austere Pacific geography. A Hub fills exactly that gap: persistent power, water, communications, and materiel-handling at the waterline, pre-established, low-signature, and one of many redundant nodes. Built to address the contested logistics environment defined at FM 4-0 ¶1-33, and to feed the predictive-sustainment system of "sensors, communications, and applications" described at FM 4-0 ¶1-53.
Concept demonstration — not a procurement, deployment plan, or final site selection. All node placements subject to host-nation consent and PE-stamped engineering. The binding constraint on this concept is connector (watercraft) survivability in contested waters; a distributed Hub network reinforces dispersal but does not by itself solve it.
Each HoloGrid Sentinel is a 20-foot ISO mil-spec container with deployable solar, onboard battery storage, atmospheric water generation, multi-bearer communications, and autonomous launch/recovery for two fixed-wing electric UAS (Skydio F10 class, in early access H1 2026). The solar array autonomously retracts for typhoon resilience. The platform is built for salt-air operating conditions using composite materials and epoxy-coated steel.
Transport is intentional: standard ISO format for ground and sealift, helicopter-liftable by a Marine Corps CH-53K King Stallion or Army CH-47 Chinook. The system arrives, levels, and powers up under its own control.
Sites visualized span the Federated States of Micronesia, Marshall Islands, Palau, Guam, CNMI, American Samoa, and adjacent Pacific waters — the second-island-chain geography and inter-chain approaches where U.S. access runs on the Compacts of Free Association and where forward distributed posture matters most. This is the geography FM 4-0 ¶6-3 names by example and ¶6-5 classifies as archipelagoes, a doctrinal littoral category.
Honesty note. A Hub is a forward distribution node and demand-reduction asset — not a stock warehouse or APS replacement. A "persistent" node is also a fixed signature, mitigated by dispersion and dual use rather than eliminated. Reference design composed from existing commercial subsystems; buildable on a short timeline once funded.
