Domestic NDAA-Compliant
Drone Propellers.
Built to Drop In.
FPV and Group 2 propellers, made in the USA — drop-in replacements for the Gemfan- and HQProp-class props US drone programs designed around and can no longer fly under NDAA flow-downs.
REGULATORY TAILWIND: Tightening FCC and NDAA restrictions on foreign UAS components
THE GAP: US programs need a domestic source for the foreign props they fly
The Why Now Moment
Federal restrictions on foreign-made UAS and their components continue to tighten — including additions to the FCC Covered List and expanding NDAA covered-country requirements that reach down to the component level.
Domestic supply for these props remains thin. US programs built around Gemfan- and HQProp-class props need a Made-in-USA source. Anvil Propulsion is building exactly that.
Building in Nevada, USA.
Made for America
We're standing up domestic injection molding for the propeller line — purpose-built for volume production, with per-unit traceability designed in from the first run. Built to be made in the USA from the resin up.
What matters to a defense buyer isn't a slogan — it's provenance. Every prop is built to be serialized, with country-of-origin documentation and a lot/serial chain of custody.
BRIDGE STRATEGY: Standing up domestic contract-manufacturing capacity while permanent tooling is established.
The Propeller Line
