## What project 0993 buys

Shipboard Air Traffic Control systems, interfacing with versions of the AN/TPX-42A(V) Direct Altitude and Identity Readout (DAIR), allow shipboard Air Traffic Controllers to identify, marshal, and direct aircraft within a 50 Nautical Mile (NM) radius of the ship. In recent years, the top 25 percent of the AN/SPN-43C frequency band has been reallocated to the Fixed Wireless Access Community prohibiting Air Traffic Control (ATC) Air Search Radar (ASR) operation within 50NM of the coast. Because the Navy requires an air traffic control surveillance radar, this project unit will include engineering efforts to identify requirements and develop the AN/SPN-50(V)1 as an AN/SPN-43C replacement system. In addition, bridging Engineering Change Proposals (ECP) will be required to sustain the AN/SPN-43C capability until the AN/SPN-50(V)1 is completely fielded. Finally, the AN/TPX-42A(V) DAIR continues to undergo several phased upgrades that have resulted in a number of field changes/technology refresh/insertion efforts. System improvements include replacing militarized front-end equipment in the track processor with open architecture Commercial Off the Shelf technology, converting the operational program software to more commonly used and flexible "C" language, providing the "hooks" for potential interface with Mode 5 Identification Friend or Foe, and integrating a flat panel monitor into the controller workstation. The ATC System Shipboard, AN/SYY-1(V) interfaces to emerging sensors as well as those currently in service to improve reliability to the fleet. The embedded training capability of the AN/TPX-42A(V) will carry on to the AN/SYY-1(V). This effort includes addressing broadened CyberSecurity requirements to remain compliant with software CyberSecurity directives and Information Assurance mandates.

**R-3 lines of work:** Product Development; Support; Test and Evaluation; Management Services.

### AN/SPN-50

Procure (V)3 EDM and begin Engineering Change Proposal (ECP) development for the AN/SPN-50(V)3 to address component obsolescence; the (V)2 is no longer procurable after FY27. The (V)3 ECP will replace obsolete parts and integrate modern software solutions that enhance performance and interoperability with other systems. ECP will also…

### AN/TPX-42

**FY2027 planned work.** Continue developing ECPs for Multi-function Console continue, as well as the implementation of Mode 5 which will require a Hardware change to SYY-1 to be able to process Mode 5. This will include the creation of a new ECP to support the efforts. The SPS-48 ECP is also another upgrade that is required to have both software and hardware upgrades to enable the SYY-1 to be able to process SPS-48 video. Due to the amount of changes that need to be incorporated, flight testing is going to be required. The flight tests necessary for supporting these efforts will occur at Wallops Island due to this being the only location to support full integration. Three separate flight test events are possible for supporting these efforts.

**FY2026 to FY2027 change.** Increase due to inflation.

**FY2026 plans — current year.** Continued as required development ECPs for Multi-function Console

### AN/SPN-43C

**FY2027 planned work.** Continue developing ECPs for AN/SPN-43C

**FY2026 to FY2027 change.** Decrease is due to the AN/SPN-43C development efforts ramping down as the system is being replaced by the AN/SPN-50 radar system

**FY2026 plans — current year.** Continue developing ECPs for AN/SPN-43C

Congressional marks, the R-2 mission description and acquisition strategy, the industry vs government split of the whole request, and related program elements are recorded at **program-element** grain — an NDAA mark lands on a PE, never on a project.
