The first unmanned aircraft of its kind to fly in the stratosphere, Zephyr harnesses the sun's rays, running exclusively on solar power, above the weather and conventional air traffic. It is a HAPS: a High Altitude Pseudo Satellite, able to fly for months at a time, combining the persistence of a satellite with the flexibility of a UAV.
Uniquely designed for both military and commercial purposes, Zephyr can deliver numerous payload capabilities across two platforms. Zephyr S with its ability to carry payloads, offering voice, data communications both line of sight and beyond the line of sight, and line of sight high resolution optical imagery. Zephyr T carrying larger payloads offers the ability to bring more active payloads to the fore; for example, widespread, persistent internet coverage to remote areas of the globe, and active RADAR. Together they enable real-time mapping, internet and a number of surveillance opportunities to meet a broad range of requirements.
Airbus has two variants of the Zephyr, designed to accommodate a variety of payloads.
The production model Zephyr S has a wingspan of 25m and weighs less than 75kg. It is able to carry see, sense and connect payloads.
Currently in development, the larger Zephyr T has a wingspan of 33m and weighs 140kg. It's a larger size enables it to accommodate payloads with larger masses
