About this opportunity
The Department of the Army Materiel Command Mission and Installation Contracting Command Yuma Proving Ground issued a sole source justification for the procurement of Vaisala Radiosonde supplies under Federal Acquisition Regulation 13.501, resulting in the award of a Firm-Fixed-Price Indefinite-Delivery Indefinite-Quantity (IDIQ) contract to Vaisala Incorporated on February 5, 2026. The contract provides expendable Vaisala RS41 GPS radiosondes (model numbers RS41-SG, RS41-SGM, and RS41-SGE) for the U.S. Army Yuma Test Center's meteorological operations, with a contract value of $3.525 million over a five-year ordering period from November 9, 2025 through November 8, 2030, supporting maximum annual quantities of up to 4,000 units. The justification for sole source award centers on Vaisala's proprietary design and exclusive compatibility with existing DigiCORA Upper Air Sounding Systems deployed across 26 Army Test and Evaluation Command test ranges valued at over $2.6 million, as well as the company's unique encrypted data transmission capabilities. A competitive alternatives analysis demonstrated that two competing vendors identified through a Sources Sought Notice were technically unacceptable due to incompatibility with Vaisala ground stations, while other acquisition approaches would have resulted in significant startup costs estimated at $1.2 million and operational constraints. The contract also extends ordering capability to other Army test facilities including White Sands Missile Range, Aberdeen Proving Ground, and Dugway Proving Ground, with a minimum order threshold of 30 radiosonde units.
