Airbus unit Aalto expands Zephyr HAPS operations in Australia

Aalto, Airbus’s high-altitude platform subsidiary, is trying to turn “almost satellites” into something investors can underwrite like infrastructure. SpaceNews reports the company is planning an Australia base to support operations of its Zephyr high-altitude pseudo-satellites (HAPS)—solar-powered aircraft designed to loiter in the stratosphere for long durations.

HAPS aim to sit between terrestrial networks and low-Earth orbit (LEO) constellations. Compared with fiber or towers, a stratospheric platform can cover remote regions without trenching, rights-of-way battles, or the slow grind of permitting. Compared with LEO satellites, it potentially offers lower latency, simpler ground equipment, and a different cost curve: fewer launches, more aviation-style maintenance.

But “cheaper than space” is not the same as “cheap.” The capex/opex split looks more like aviation than telecom: specialized airframes, launch-and-recovery operations, spare parts, and a trained workforce on the ground. The Australia base is essentially a bet that utilization rates can be pushed high enough to amortize that operational burden across paying customers.

The likely customer set is also infrastructure-like: telecom backhaul in sparse geographies, government and defense ISR/communications, and resource industries (mining, energy) that already pay a premium for connectivity. Those customers value resilience and rapid deployment—especially when undersea cables, towers, or satellites become geopolitical targets.

Then come the unglamorous blockers that decide whether this becomes an asset class or a demo project: spectrum rights, airspace permissions, cross-border service rules, and insurance. A HAPS is not regulated like a satellite, but it’s also not a normal aircraft. Liability and coverage questions—especially over inhabited areas—can dominate unit economics.

If Aalto can standardize operations, HAPS could become a credible third lane of connectivity—one that competes not by technological mystique but by a spreadsheet: cost per covered square kilometer, uptime, and regulatory friction. That would be a welcome change from the usual “space will fix it” pitch decks.
