The purpose of this solicitation is to seek Industry solutions to deliver a prototype radar that is integrated into a ship-based platform for collection of data supporting MDA flight testing. In this context, provisions for maritime operations include ship motion. MDA is seeking a proven technology base, supported by active production line(s), and leveraging a continuing sustainment infrastructure. MDA will focus on acquiring a prototype system anchored on proven commercial/government-off-the-shelf (COTS/GOTS) technologies to accelerate the delivery schedule, reduce costs, and minimize programmatic risks for the delivery of a prototype SPAIR. MDA intends to execute this procurement in two phases. Phase I will competitively select an Offeror(s) to develop and deliver a full design for the proposed radar to include System Requirements Review (SRR), Preliminary Design Review (PDR), Critical Design Review (CDR) and integration of the radar into the ship design. The MDA may request a Phase II proposal from the selected Offeror(s) for the full prototype development, delivery, installation, integration, testing and achievement of Initial Operational Capability (IOC)/Final Operational Capability (FOC) based on the approved design delivered in Phase I. The Government reserves the right to select one, all or none of the proposals provided for Phase I. Performers will be required to access, handle, receive, and store SECRET information in performance of this effort. Offerors must have an active SECRET (or higher) Facility Clearance (FCL) with SECRET (or higher) Safeguarding Level to be eligible to respond to this solicitation. The “Offeror's Library” with CUI data is available for Offerors with an active SECRET (or higher) FCL with SECRET (or higher) Safeguarding Level. The Offeror's Library contains requirements and background information for Phase I and II. To Request Access to the Offeror's Library: Interested Offerors must have a Facility Security Officer (FSO) email the following information to mda.spair@mail.mil: Company name and official mailing address FSO contact information Commercial and Government Entity (CAGE) Code
