WindBorne Systems secured a US Air Force contract worth up to $49 million for atmospheric data from its global fleet of 700 autonomous weather balloons. Operating on a pay-as-you-go model, the deal supports constellation expansion and R&D. The company leverages real-time data for its AI WeatherMesh6 model, which outperforms traditional physical models, and recently completed a $37 million Series B round. This non-bid award recognizes WindBorne's unique capability to meet specific operational needs, marking its largest deal to date.
