One adapter. Every C2.

C2-ready for every buyer —
without rebuilding for each deal.

Write one adapter. Reach every C2. Musubi is the neutral, open-source layer that turns your UAV, USV, UGV or AI-sensor's telemetry, tracks and AI outputs into mission-ready evidence — delivered in each C2's native form, and built to prove how your platform holds up under comms loss and GPS degradation. Open and neutral — so no single C2 vendor locks you in.

The problem

The integration tax: N platforms × M C2 systems

  1. No C2-readiness, no deal

    Interoperability with existing C2 is becoming a procurement gate. Platforms that aren't C2-ready get screened out — and every new market you export into adds another C2 to satisfy. Worse, makers have no objective way to prove how a platform holds up under comms loss and GPS degradation.

  2. You build platforms, not C2

    You want to sell your vehicle or sensor — not build a command system. But every buyer asks the same question: how does this connect to our existing C2?

  3. Rebuilt every deal

    Today that means hand-writing a new integration for each C2. N platforms times M C2 systems is a bespoke, rebuilt-every-PoC tax — and the deeper you go through proprietary APIs, the worse the lock-in.

Why now

Interoperability is the bottleneck — and defense budgets are surging.

Europe is mobilizing for defense at historic scale — the European Commission's ReArm Europe / Readiness 2030 plan targets up to €800 billion — and Japan has publicly stated it will grow defense spending. As budgets rise, the constraint shifts from buying platforms to making them work together. C2-readiness is becoming the gate, and the makers that clear it first win the deals.

The solution

Connect once. Normalize every mission.

Write one adapter against Musubi's canonical schema, and your platform is built to reach every supported downstream C2 through the same evidence-backed output — no per-C2 rework.

  1. 01

    Connect once

    One adapter from your platform into Musubi.

  2. 02

    Musubi normalizes

    Into read-only, evidence-backed claims — never commands back to your vehicle.

  3. 03

    Every C2 receives it

    Delivered to each C2 in its own native form.

How you plug in — one adapter, delivered to every supported C2· roadmap

Enters thin — software, not a box

Musubi is software (a container) that rides on your existing companion computer, GCS or server. No dedicated hardware, no platform redesign.

One canonical model

One capability-based adapter set normalizes common stacks (MAVLink/PX4/ArduPilot, ROS2/DDS, RTSP/ONVIF, MQTT/REST, vendor SDKs, GCS logs) into a single object model — so a degraded asset still reports “comms degraded, sending event summary” instead of dropping off the map.

One adapter. Every C2.

Connect once. Normalize every mission.

Built to pass security review

Read-only by design. Hostile inputs assumed by default.

Read-only & untrusted-input posture
Read-only by design, deny-by-defaultREAD-ONLY
Musubi cannot command your vehicle or sensor. Write and control permissions are denied unless explicitly declared, and any adapter requesting write or control access fails the default policy. Integrating Musubi adds no write or control surface to your platform.
Untrusted by designUNTRUSTED
Musubi assumes hostile, malformed and misleading inputs — spoofed telemetry, replay, stale data, prompt injection — and runs schema, signature, provenance and anomaly checks before anything becomes a Claim.
Signed is not trustedVERIFY
Origin signing proves where a message came from, not that it is true. Musubi adds replay, time-drift, impossible-movement and cross-sensor contradiction checks on top, and flags risk rather than asserting authenticity.
AI outputs are claims, not commandsCLAIM-ONLY
Your edge-AI detection is delivered as a confidence-tagged Claim with its model identity and known failure modes — attributable and consumable, never given authority and never presented as truth. Examples and demos use mock data only.
The boundary

Musubi makes the Claim. Your C2 makes the call.

Musubi — the Claim layer

“I saw it / it looks like this / here is the evidence / here is the confidence / here is the risk.” Musubi states what it observed, with provenance and confidence — and stops there.

Your C2 — the judgement

Adopt, hold, discard, approve, who-sees-what, which-mission — the judgement stays with your existing C2, or a planned downstream trust layer such as KECKU's own Raijin (roadmap). Musubi proposes; it never decides.

What Musubi is not

No engagement or targetingNo fire-control decisionsNo commands to your vehicleNot a weapons or control systemNot a C2 or a map

Read-only is why Musubi can sit in front of any C2 without becoming a rival to it — neutrality and the kill-chain boundary are the same property. Musubi proposes claims; your C2 decides.

Roadmap · On the roadmap: each Claim travels inside an open, portable, signed Evidence Envelope — source and adapter identity, confidence, provenance and risk flags — so your output stays auditable and a customer's exit is never a full rewrite. Where a downstream C2 can't carry the trust metadata, confidence and provenance are marked, never silently dropped.

The contested edge

Built for degraded links — and made provable

DDIL-native

Your data survives comms loss and intermittent links — store-and-forward, differential sync, dedup-on-resend and clock-skew detection keep original timestamps and provenance intact.

Failure is a first-class object

roadmap

Comms loss, GPS degradation, video latency and false detections are recorded, not silently dropped — so they become demonstrable, comparable data instead of unknowns.

Adversarial eval & replay

roadmap

A planned eval/replay harness (roadmap) injects comms loss, GPS jumps, fake and replayed telemetry, video delay and metadata prompt-injection, then produces a comparable report — the objective harness makers otherwise rebuild deal by deal. Design partners help shape it and get first access.

Prove resilience once and reuse it across buyers — mission logs, evidence and degraded-comms behavior become selling points instead of unknowns. (Eval and AI-claim examples use mock data; no models are trained on real, operational or classified mission data.)

Your door to Japan

Reach every major C2 — including a documented door into Japan

Against the backdrop of Japan's publicly stated direction to grow defense spending, integration demand is rising. KECKU is your partner on the ground in Tokyo, and Musubi is your documented door to SHIELD — a Japanese C2 Musubi is built to deliver into — so your platform can arrive C2-ready and PoC-ready.

Neutral by structure: open-source governance and a conformance suite keep Musubi a shared standard, not a walled garden. DELTA, NATO MIP, TAK and SHIELD are destinations Musubi is designed to deliver into — partnering with us does not hand your roadmap to any one C2 vendor.
