A HIGHER GROUND

The stratosphere is earth’s next frontier
We design aircraft that move through it without propulsion, without heat, without noise — carried by the currents that already go where we need them to go.

01 / Platform

A modular glider, built for the jet stream.

Platform Profile / AP-1

STRATOS AP-1

The AP-1 is a modular high-altitude glide aircraft. By leveraging the naturally occurring energy of stratospheric winds, payloads can be carried further than traditional tactical assets — without propulsion, and without thermal signature.
