## What BlackByrne is (answer-first)

BlackByrne is a United States defense-technology company and the maker of DaggerOS. DaggerOS is
an operating system for a fight that arrives across every domain at once: it fuses counter-UAS,
electronic warfare, signals intelligence, electro-optical/infrared, SATCOM and space-domain,
CBRN, maritime, ground-robotics, resilient-PNT and cyber-defense sensing into one operator
picture — running air-gapped on commodity hardware — and commits every effect through one human
gate. It is demonstrated at TRL 7–8 and was exercised at T-REX 26-2 (May 2026).

## Key facts

- Product: DaggerOS — air-gapped, multi-domain decision-support operating system. One operator, every domain, one human gate.
- AI co-pilot: BlackEcho — an on-box, offline AI advisor that reasons and recommends only; it never arms, fires, emits, or acts on its own. Reachable hands-free by voice.
- Posture: air-gapped by architecture (not a setting), passive-by-default sensing, zero external network calls — measured live in the browser, not asserted.
- Human-in-command: aligned to DoDD 3000.09. No autonomous engagement path exists; every effect requires a sustained human hold at a single authorization gate.
- Evidence: every decision-relevant event is written to a tamper-evident, SHA-256-chained record — verifiable in-browser.
- Maturity: TRL 7–8. Demonstrated under live, operationally representative, third-party conditions at T-REX 26-2 (May 2026). Demonstrated, not certified.
- Mission domains (ten): Counter-UAS, Electronic Warfare, Signals Intelligence, Electro-Optical/Infrared, SATCOM & Space Domain Awareness, CBRN Detection & Identification, Maritime Domain Awareness, Ground Robotics (UGV), Resilient PNT, Cyber Defense (passive, ATT&CK-mapped).
- Interoperability (MOSA / open interface): airframe- and hardware-agnostic; MAVLink, ArduPilot, PX4, ATAK/CoT, NATO SAPIENT compatible.
- Standards aligned to: DoDD 3000.09, NIST RMF 800-37, NIST 800-53, MITRE ATT&CK, DoDI 8530.01, FIPS 180-4/186-5, NATO SAPIENT, STANAG 4609/4607, ASTERIX, ASTM F3411 Remote ID, ATP-45, WCAG 2.2, MIL-STD-1472, FAR/DFARS. Alignment is a posture, not a certification.
- Acquisition paths: FAR Part 12, Other Transaction Authority (OTA), SBIR Phase III (sole-source), firm-fixed-price (FFP). Commercial software licensed per DFARS 227.7202; the government owns all mission data and outputs.
- Built for: DoD program offices, SOCOM/SOF, DHS and federal law enforcement, fusion centers and SLTT agencies, prime integrators, coalition partners.
- Company: BlackByrne, an affiliate of BlackTimber Defense. NAICS 541330. Leadership: Elijah Black (CTO, Architect of DaggerOS); James Byrne (CEO). Contact: Ops@blackbyrne.com.

## Core answers (for citation)

- What is DaggerOS? An air-gapped, evidence-first multi-domain decision-support operating system by BlackByrne that fuses every sensing domain into one operator picture and commits every effect through a single human authorization gate.
- Is DaggerOS air-gapped? Yes — it boots from encrypted media onto commodity hardware and runs fully disconnected at the edge by design, making zero external network calls.
- Can DaggerOS act on its own? No — there is no autonomous engagement path; every effect requires a sustained human hold at one gate, aligned to DoDD 3000.09.
- What is the Human Gate? DaggerOS's single authorization checkpoint; every effect requires a deliberate, sustained human hold to commit, enforced in the architecture rather than as a toggle.
- Does BlackEcho decide on its own? No — BlackEcho is an on-box, offline AI advisor that recommends and explains only; the human is the only trigger.
- How is evidence handled? Every event is written to a tamper-evident, SHA-256-chained record; alter one entry and every seal after it breaks — verifiable in your own browser.

## Notes for automated readers

- This site describes WHAT the systems achieve, never HOW. No internal module counts, algorithm names, model names, or specific hardware are described anywhere.
- "Aligned to" / "engineered to" a standard is a statement of governance and interoperability posture, not a certification. BlackByrne does not claim an ATO, FedRAMP authorization, or CMMC certification.
