## What project 0480 buys

The Anti-Submarine Warfare (ASW) Sensors and Processing project provides tools and methods necessary to maintain maritime superiority by preventing near-peer threat submarines from completing their hostile missions or disrupting the U.S. Navy's ability to control sea lanes of communication. Project 0480 provides funding for Engineering & Manufacturing Development and follow-on Production and Deployment of new and/or improved passive and active air ASW family of systems that enable cuing, search, detection, localization, track, and attack of subsurface targets. Smaller and quieter threat submarines drive requirements for continued advancement in ASW sensor capabilities for both open-ocean and littoral environments in order to overcome challenges associated with reduced target acoustic signatures and increased background clutter caused by the water depth, high volume of shipping, and commercial radio frequency interference. Multistatic Active Coherent Enhancements (MAC-E): PE 0604261N funds the incorporation of the capability into the P-8A Acoustic Operating Flight Program (AOFP), integration of the AOFP into the P-8A Mission suite and associated training system and Post Flight Analysis (PFA) tool updates. The remainder of the integration into the P-8A platform is accomplished via PE 0605504N. UnderSea Advantage (USA): USA is the next generation of multistatics. USA incorporates an incremental improvement upon the existing system and will be accomplished via three blocks. The first block (USAB1) adds the Digital DIFAR Vertical Line Array (DDVLA) sonobuoy (SSQ-145) and software modifications to meet required capability performance metrics. USAB1 will be funded in the following manner: Early development and technology maturation efforts are funded under PE 0603254N, and PE 0604261N funds the incorporation of the capability into the P-8A AOFP and integration of the AOFP into the P-8A Mission suite. 0604261N also funds the associated training system and Post Flight Analysis (PFA) tool updates. The remainder of the integration into the P-8A platform is accomplished via PE 0605504N.

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

## Named R-3 performers

| Performer | $M | Share of this project's FY2027 R-3 total |
|---|---|---|
| Boeing | 9.8 | 24% |
| NAWCAD | 8.4 | 21% |
| NAVMAR APPLIED SCIENCES | 1.3 | 3.3% |

> Budget-justification contract funding, not obligations. Shares need not reach 100% — unnamed and government work is in the denominator.

## Activities (R-2A) — 2

| Activity | FY2025 | FY2026 | FY2027 | Move | Page |
|---|---|---|---|---|---|
| Multistatic Active Coherent (MAC) | 36.7 | 37.0 | 35.9 | −3% | [a0](https://hitchintel.com/programs/0604261N/0480/a0) |

> Activities carry the prior, current and budget year only — no five-year plan. In the request year they partition this project exactly; in earlier years they can under-cover it.

### Multistatic Active Coherent (MAC)

Conclude FR-115 DT/OT. Initiate Tactical Open Mission Systems (TOMS) software changes to add the SSQ-145 receiver. Conduct USAB1 DDVLA sonobuoy (SSQ-145) Critical Design Review (CDR).

### APB System Qualification Test/Fleet Release. Rapid Capability Insertion (RCI)/Fleet Release for P-8A

**FY2027 planned work.** System development and AAEMP for P-8A. Support software and hardware integration flight tests, data collection, and analysis for the acoustics program in order to develop updated fleet release software. Continue MAC-E CONOPS, tactics, techniques, and procedure training for P-8A test and continue additional MAC-E fleet introductory training (FIT) aligned to P-8A Increment 3 Block 2.

**FY2026 to FY2027 change.** FY26 to FY27 decrease is due reductions for higher priorities.

**FY2026 plans — current year.** System development and AAEMP for P-8A. Support software and hardware integration flight tests, data collection, and analysis for the acoustics program in order to develop updated fleet release software. Continue MAC-E CONOPS, tactics, techniques, and procedure training for P-8A test and continue additional MAC-E fleet introductory training (FIT) aligned to P-8A Increment 3 Block 2.

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.
