The Department of Defense, specifically the United States Special Operations Command (USSOCOM), is seeking vendors to provide engineering and technical services for a meteorological upper-air collection system that does not utilize helium as a lifting mechanism. The procurement aims to develop and produce weather data collection sensors capable of operating at high altitudes, with a focus on technology readiness at TRL 6 or higher and the ability to collect various meteorological parameters. This capability is crucial for enhancing operational effectiveness in diverse environments. Interested vendors are encouraged to submit their responses by March 4, 2025, including company background and capability details, to primary contact Danny Soto at danny.soto3.civ@army.mil or secondary contact Joshua Weigartz at joshua.t.weigartz.civ@army.mil.
