WindBorne Systems, a startup based in Redwood City, California, has secured a contract with the U.S. Air Force valued at up to $49 million. The agreement utilizes a call-off model, allowing the military to purchase atmospheric data for specific regions and timeframes as needed. To date, the Air Force has placed orders totaling approximately $1.7 million.

The contract supports the use of WindBorne’s fleet of approximately 700 autonomous weather balloons. These unpowered systems use deep-learning technology and atmospheric models to navigate wind currents and adjust altitude. The company recently demonstrated this capability by guiding a system into the eye of a typhoon to collect data. 

The data collected by the balloons feeds into the company’s proprietary AI-driven forecasting model, WeatherMesh 6, which aims to provide more accurate forecasts than traditional physics-based models by integrating real-time empirical sensor readings.
