WHY +SHIELD · DOC 01

Four pillars

COST ASYMMETRY

SwarmWall intercepts at a fraction of conventional missile defence cost. Patriot PAC-3: ~$4M per intercept. +Shield: orders of magnitude less.

HUMAN-IN-THE-LOOP

Fully autonomous lethal engagement is a hard red line. Every kill decision authorised by a human operator through +ROP biometric authentication.

SOVEREIGN BY DESIGN

Zero US-dependency communications. Five-layer +Grid stack: LoRa FHSS, UWB, SDR, OneWeb/Eutelsat, acoustic infrasound.

NATO PROCUREMENT READY

Built against NATO STANAG specifications. EU-manufactured. Compatible with allied vehicle and naval platforms.

THE THREAT · DOC 03

The cost equation is broken

European airspace is contested. Loitering munitions, cruise missiles, and increasingly hypersonic vehicles outpace legacy air defence economics. Defenders cannot sustain $4M intercept costs against $20K attack drones. +Shield reverses the cost equation.

~$4M per intercept against a $20K drone. That equation is unsustainable.

DOCTRINE

Human-in-the-loop is non-negotiable

No +Shield system performs autonomous lethal engagement. A human operator authorises every kill decision via +ROP biometric authentication. This doctrine is engineered into the architecture, not bolted on.
