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.

Project 0993 funding, FY2025–FY2031
Prior years are actuals, the budget year is the request, and the outyears are the FYDP plan. Estimate types are colored and never summed into one figure. Projects carry the full five-year plan; the activities inside them stop at the budget year.
| Fiscal Year | Estimate Type | Amount ($M) |
|---|---|---|
| FY2025 | Actual | 8.6 |
| FY2026 | Enacted | 8.3 |
| FY2027 | Request | 25.8 |
| FY2028 | Outyear | 21.4 |
| FY2029 | Outyear | 20.2 |
| FY2030 | Outyear | 13.9 |

3 accomplishments / planned programs
The R-2A exhibit — the only level of the budget that describes work that has not happened yet. Activities carry the prior, current and budget year only, no five-year plan. 1 of them describes FY2027 work in enough detail to have its own page; the rest are shown here in full. Coverage is partial across the corpus, so count activities, never total them.
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…
Read the FY2027 plan →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…
FY2026 to FY2027 change Increase due to inflation.
FY2026 plans — current year Continued as required development ECPs for Multi-function Console
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
Named performers on project 0993
Performers named in the R-3 exhibit under this project. Share is of the project's whole FY2027 R-3 total — the same denominator the program-element split uses, so the two read on one scale and will not sum to 100% when unnamed or government work is in the mix. Budget-justification contract funding, not obligations.
