The Naval Undersea Warfare Center Division Newport intends to award a firm-fixed-price purchase order on a sole-source basis to BAE Systems for four NavGuide Production units (Part # 766-0000-001), which replace discontinued DAGR units. BAE is identified as the only manufacturer of a GPS receiver with SAASM and M-Code capability that meets the required form factor and computer interface, and switching receivers would require a complete hardware/software redesign. Delivery is F.O.B. Destination to Newport, RI 02841 and must occur within twelve months after receipt of order. This is not a request for competitive quotes, but the government will consider responses solely to determine whether to conduct a future competitive procurement. The NAICS code is 517410 with a small business size standard of $44,000,000, and offerors must be registered in SAM and provide required quote information, including price, delivery terms, point of contact, CAGE code, and Unique Entity ID.
