## Summary

U.S. Navy funding falls 40% to a $20.1M request in FY2027 (down from a FY2026 peak), sustained across the five-year plan. In the FY2027 defense authorization, the House funded it in full; the Senate funded it in full; House appropriators funded it in full. NAWCAD leads the industry work.

### Project 1292 — Adv ASW Sensors & Proc

This program improves Air Anti-Submarine Warfare (ASW) effectiveness through development and maturation of advanced hardware and software associated with airborne acoustic and non-acoustic sub-systems. This includes sensors and components, data recording, processing, post-processing and display capabilities to address near-peer threat scenarios against surfaced or submerged conventionally and nuclear powered submarines. Key objectives include: advancing active and passive sensors and components; improving detection, classification, localization and tracking; and increasing capacity and flexibility to handle multi-sensor data loads. Technology evaluations include sonobuoy communication links to/from aircraft, distributed netted sensors, transient signals, and source and receiver technologies that will enhance passive and multistatic active sensor systems. Products being funded will provide for the development and maturation of persistent tactical search technologies that will allow transition to the localization and attack phase in operationally relevant environments. In addition, the program will provide for the development and subsequent experimentation, including data collection and engineering measurement, of the next generation of multistatic sources and receivers; passive sensors and processors; and non-acoustic technologies. Matured technologies that increase operational capability will transition to acquisition programs of record for eventual release on ASW platforms. The RDT&E test articles reflect the upper unit quantities for early USAB2 prototyping.

**Named R-3 performers** (share of this project's FY2027 R-3 total, so they need not reach 100%)**:** NAWCAD (7.8, 39%).

| Activity (R-2A) | FY2025 | FY2026 | FY2027 |
|---|---|---|---|
| System performance assessments | 18.1 | 18.9 | 20.1 |

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

### Project 9999 — Congressional Adds

Congressional Add. Mid-Frequency Active Sonobuoy (MFAS) Development and Prototype.

## Where the FY2027 request goes

| Category | Share | $M |
|---|---|---|
| Industry primes | 39% | 7.8 |
| Other / unspecified | 61% | 12.3 |

**Top named industry performers:** NAWCAD ($7.8M, 39%).

> R-3 exhibit contract funding, not USAspending obligations.

## Mission & acquisition strategy

This program improves Air Anti-Submarine Warfare (ASW) effectiveness through development and maturation of advanced hardware and software associated with airborne acoustic and non-acoustic sub-systems. This includes sensors and components, data recording, processing, post-processing and display capabilities to address near-peer threat scenarios against surfaced or submerged conventionally and nuclear powered submarines. Key objectives include: advancing active and passive sensors and components; improving detection, classification, localization and tracking; and increasing capacity and flexibility to handle multi-sensor data loads.

Develop and mature acoustic and non-acoustic ASW technologies that have high potential for meeting documented capability gaps and Fleet requirements. As funding permits for technology maturation, transition those technologies to acquisition programs of record for eventual Fleet release on ASW platforms.
