The thesis

Mass production.

Modern warfare needs thousands of precision systems, not hundreds. Every airframe is built for it - tool-less assembly, low-specialization labor, distributed across allied territory.

Visual navigation system output - AI terrain matching in a GNSS-denied environment

Sovereign autonomy

It flies and strikes without GPS.

A vertically integrated stack - AES-256 encrypted datalink, visual navigation and AI targeting that hold precision in GNSS-denied, jammed environments.

Cost

A lower cost per effect.

Built on a proven jet architecture and engineered for mass production - a fraction of the unit cost of comparable jet-class UAS.

XQ 770 Freedom Fighter, side profile

Scale

Built for arsenal-scale output.

Designed for distributed assembly and rate production - thousands of systems across allied territory, not dozens.

Forged in combat

Built in the war that is defining the future of defense.

Operating today on the Ukrainian front against Russian forces - every system is shaped by the fight it was made for.

Arsenals of Democracy

Manufacturing across allied territory.

Design and manufacturing integrated in-house - production placed close to the fight.
