The Department of Defense, through the NAVSUP Fleet Logistic Center Norfolk, is seeking contractors to provide data-encrypted autonomous in-situ subsurface profiling systems, specifically air/surface-deployable profiling floats, for meteorological and oceanographic operations. These floats must meet stringent NAVOCEANO standards, including the ability to transmit encrypted data via Iridium Satellite communications, collect critical environmental data such as salinity, temperature, and pressure, and operate unattended for extensive profiling cycles. The contract will be structured as a Firm Fixed Price (FFP) multiple award Indefinite Delivery, Indefinite Quantity (IDIQ) contract with a three-year ordering period, anticipated to commence on September 23, 2026, following an award around August 24, 2026. Interested vendors should ensure they are registered in the SAM database and may contact Borui Tang or Joseph Caltagirone for further information.
