### Project 3311 — Navigation Systems

Effective in FY 2026, Project 3311 Navigation Systems moved from PE 0204228N to PE 0607658N as part of the PE/BLI consolidation effort in the DoW Implementation Plan from the Commission on PPBE Reform Final Report. The Surface Support RDT&E funding will be used for the research, design, development, integration testing, and documentation of the Inertial Navigation System (INS) AN/WSN-12 for all Navy ships and submarines. The INS provides mission critical ship position and attitude data to shipboard sensors (such as radars), combat and weapon systems. The INS uses data from the Global Positioning System (GPS) to periodically update (i.e., reset) its position and internal clock. The INS is the ship's primary position source in the absence of GPS, and it consists of an Inertial Sensor Module (ISM) and a Navigation Processing Module (NPM) that will provide a significant improvement with respect to attitude and velocity data over previous INS. RDT&E funding will support continued system design to create a baseline for Pre-Production Units (PPU), Low Rate Initial Production (LRIP), and Full Rate Production (FRP). Military GPS User Equipment (MGUE) will provide assured Positioning, Navigation, and Timing (PNT) in a GPS degraded environment. Funding will be used for the development of interface and performance requirements, shipboard system architecture definition, and MGUE integration. Submarine Speed Sensors will provide investigation, development, testing and integration of new Own-Ship Speed sensors to address new capabilities, reduce detection, and improve reliability. Automated Celestial Navigation System (ACNS) funding will be used for the research, development, Engineering Development Model (EDM), documentation and integration testing of the celestial navigation solution for the NoGAPSS navigation implementation on the fleet. Efforts will leverage ONR celestial navigation research into a reproducible ruggedized system fully integrated into the navigation suite.

| Activity (R-2A) | FY2025 | FY2026 | FY2027 |
|---|---|---|---|
| AN/WSN-12 Inertial Navigation System - Replacement (INS-R) | 4.2 | 0.0 | 0.0 |
| Submarine Speed Sensors (SSS) | 2.0 | 0.0 | 0.0 |
| Automated Celestial Navigation System (ACNS) | 1.0 | 0.0 | 0.0 |
| Navigation Support | 1.2 | 0.0 | 0.0 |

> R-2A activities carry the prior, current and budget year only — no five-year plan. Coverage is partial, so count them, never total them.

## Mission & acquisition strategy

Effective in FY 2026, Project 3311 Navigation Systems moved from PE 0204228N to PE 0607658N as part of the PE/BLI consolidation effort in the DoW Implementation Plan from the Commission on PPBE Reform Final Report. Through FY 2025, the focus of PE 0204228N (Surface Support) is for the research, design, development, integration testing, and documentation of the Inertial Navigation System (INS) AN/WSN-12 for all Navy ships and submarines. The INS provides mission critical ship position and attitude data to shipboard sensors (such as radars), combat and weapon systems.

AN/WSN-12 Inertial Sensor Module (ISM) sole source production contract awarded in FY 2023. ACNS top-side sensor sole source production contract awarded in FY 2023
