This sole source justification document relates to solicitation number N0018923Q0526 from the Department of the Navy Naval Supply Systems Command for the procurement of a Nortek Coastal USV: Signature1000 VM Acoustic Doppler Current Profiler (ADCP). The justification requests approval to procure the ADCP as a sole source item, as it requires a specific product from Nortek to meet technical and operational requirements for an unmanned surface vehicle platform. The justification cites the need for compatibility with existing Nortek software and hardware used for other Navy projects, as well as the lack of other viable alternatives that could meet required specifications for accuracy, range, and integration onto the USV in the necessary timeframe. Approval is requested by the listed date to ensure delivery of the ADCP unit prior to the start of the field season.
