Hello from Wales.

Why we chose the Conwy valley, what we are trying to build, and our working thesis — that the next generation of allied defence kit will be built by small, vertically-integrated teams that write their own code.

Founding

Why we chose ML-KEM-1024 for Cipher OS.

A walk through the post-quantum parameter choice, the hybrid design, and where classical ECDH still earns its place in the stack.

Engineering

DF-5 wing box: first composite layup.

Photos and notes from our first autoclaved wing-box spar, cured this week at a Welsh composites partner. Weight came in 4% under target.

Programme

We will only sell to the UK, the US, and their allies.

Our customer policy, our reasoning, and how we apply it to everything from briefings to open-source contributions.

Policy

Pod design: the container variant, from the inside.

A virtual walkthrough of the DF-POD-C — what each of the seven stack bays does, and why the thermal bay is where we have spent the most time.

Engineering

We are hiring our first ten engineers.

Who we are looking for, what we pay, how we interview, and why the best defence careers in Europe right now are in a small town in north Wales.

Hiring

Sovereign silicon: why we package our own SoC in Wales.

The DF-5 and the Cipher Terminal both run on the Dragonfod C1 — an ARM64 SoC whose back-end packaging happens in Newport. Here's why that matters and what it costs.

Engineering

Cipher OS 0.9: what's in the pre-alpha.

A changelog and architecture overview of the first milestone build. Post-quantum handshake, mesh routing, and the audit ledger — running on real hardware in the lab.
