An American engineering company building unmanned rocket systems and layered defense platforms.
One Defense exists to give the United States and allied forces a decisive, dependable edge — through unmanned rocket systems, sensing networks, and command software engineered to the highest standard of mission assurance.
We are privately held and mission-focused. This site is intentionally limited to public program information — it does not include contact directories, personnel listings, or financial disclosures.
Every system is tested to fail safe, perform predictably, and hold up under real operational stress.
Our command software logs every decision path — auditability is a design requirement, not an afterthought.
We iterate our hardware and software fast enough to stay ahead of evolving threats.
One Defense airframes, avionics, and software are engineered and produced in the United States, in support of U.S. national security priorities and allied mission partners.
Founded by a small team of propulsion and guidance engineers to build a faster path from concept to fielded unmanned systems.
Completed first instrumented flight test of the ONE-Vanguard airframe at a U.S. test range.
Started development of the Sentinel command-and-control software to unify sensor and effector data.
Opened our first dedicated production line for ONE-Vanguard airframes and avionics.
ONE-Vanguard reached 12 consecutive successful flight tests; Sentinel C2 entered operational testing.
One Defense designs, builds, and audits its systems against the frameworks the U.S. government requires of its industrial base.
Illustrative footprint of One Defense engineering, production, and test locations. Exact coordinates are withheld from public disclosure.
We design and manufacture unmanned, pointed-nose rocket systems (ONE-Vanguard) and the Sentinel family of integrated sensor-fusion and command-and-control software for U.S. national security missions.
