GPNTS JA Redact Version Redacted.pdf

This document is a Justification and Approval (J&A) for a sole source contract modification for the Global Positioning, Navigation, and Timing System (GPNTS) software support services. The contract with Raytheon (Contract N00039-20-D-0021) is being modified to increase the ceiling from $100,345,487 to $180,945,487, with an estimated value of $80,600,000. The modification will support critical Positioning, Navigation, and Timing (PNT) data for over 70 systems across multiple military platforms, including Aegis, Ship Self Defense System, Navy Multiband Terminal, and Foreign Military Sales.

The justification highlights the complexity of GPNTS software development, noting the need for a software re-baseline from v1.x to v2.x to address defects, software end-of-life, and hardware obsolescence. Raytheon is the original designer and developer, and using another vendor would cause an estimated 36-month delay in meeting Navy requirements. The contract modification will enable continued engineering support through the end of FY29, with non-recurring engineering costs totaling $80.6 million across different engineering support categories. The Navy plans to maintain the current vendor to ensure continuous software development and support without disrupting critical fleet requirements.
