- Military balloons now launch reusable drones directly from the stratosphere
- Solar-powered Apollo-R remains airborne for weeks after balloon deployment at altitude
- Thunderhead balloon carries multiple drones during a single high-altitude deployment mission
High-altitude balloons are moving beyond surveillance roles as military developers explore using them as airborne launch platforms for long-endurance unmanned drones.
According to Aerostar, its Lightning balloon, paired with the solar-powered Apollo-R drone from Icarus, has now demonstrated a workable path toward stratospheric drone carriers.
Recent testing reportedly showed the balloon successfully releasing a single high-endurance uncrewed aircraft while cruising high in the open stratosphere.
Lightning and Thunderhead offer different endurance profiles
The Lightning platform operates for up to three days at altitudes between 50,000 and 78,000 feet, carrying payloads of up to 45 pounds.
Aerostar's larger Thunderhead balloon covers a similar altitude band, between 55,000 and 75,000 feet, but stays aloft for 60 days or more.
