## Summary

U.S. Navy requests $390.3M in FY2027, 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. Northrop Grumman leads the industry work, though an unusually large share flows to government labs and warfare centers.

### Project 3051 — E-2D Adv Hawkeye

The DSSC build schedule is outlined below along with the capabilities that are planned to comprise each DSSC build. 1. DSSC-5.1 will provide a Counter Electronic Attack (CEA) capability which will allow the E-2D radar system to maintain performance in an advanced hostile intentional electromagnetic interference environment. CEA will ensure continuous E-2D effectiveness is maintained in an Electronic Attack environment supporting the Navy Integrated Fire Control (NIFC) capability and overall Navy and Joint Integrated Air and Missile Defense strategy. 2. DSSC-5.1 and 5.2 will provide phased E-2D Data Fusion Improvements for a fusion engine to blend on and off-board sensor derived track data (e.g. Electronic Surveillance, Satellite Receiver System data, Fighter to Fighter backlink data) with already blended radar, Identify Friend or Foe and Cooperative Engagement Capability track files, enhancing situational awareness and tactical decision making. Integrating Link-16 Network Participation Group 20 messages improves interoperability between E-2D and participating US Navy fighters, including 5th generation aircraft. This enhances the combat effectiveness of the E-2D, increases situational awareness and shortens kill-chain timeliness (including NIFC). Successful E-2D NIFC employment depends on a clear/unambiguous tactical picture. 3. DSSC-5.2 provides phased E-2D Cooperative Engagement Capability (CEC) Signal Data Processor (SDP) processing capacity and cryptographic upgrades required to implement the NIFC capabilities integrated into DSSC-5. CEC utilizes the SDP to encrypt tactical data and control the antenna during transmission of the data. This capability will correct obsolescence deficiencies based on processors, encryption, and capacity and establish the baseline architecture for expanded capability in CEC. The fully integrated E-2D Communication-as-a-Service (CaaS) will enhance CEC improvements to ensure resilient communication paths for tactical information throughout the battlespace. CEC Block II capabilities will ensure continued interoperability with the rest of the carrier strike groups and enable new CEC capabilities necessary to counter expected advances in threat capabilities. Initial integration of CEC Block II capabilities must be conducted on time to maintain interoperability and keep pace with expected threats. 4.

**Named R-3 performers** (share of this project's FY2027 R-3 total, so they need not reach 100%)**:** Northrop Grumman (146.7, 38%), NAWCAD (47.8, 12%), Rockwell Collins (10.3, 2.6%), NAWCWD (8.4, 2.1%).

| Activity (R-2A) | FY2025 | FY2026 | FY2027 |
|---|---|---|---|
| Air Vehicle | 10.2 | 12.9 | 11.0 |
| Mission Systems | 187.5 | 215.9 | 284.0 |
| Integration, Test, and Training | 83.0 | 121.5 | 95.3 |
| Classified DSSC Support | 0.2 | 0.0 | 0.0 |

### Project 9999 — Congressional Adds

Congressional Add. The E-2D Advanced Hawkeye and associated APY-9 radar meet the requirements specified in the Capabilities Development Document (CDD), including detection ranges, detection velocities, and tracking accuracies, verified through extensive developmental and operational flight testing and deployed operations. Program increase for E-2D advanced radar development to stay ahead of the evolving threat.

E-2D Milestone C Acquisition Strategy was approved by Milestone Decision Authority, Under Secretary of Defense for Acquisition, Technology and Logistics (USD(AT&L)) on 29 Dec 2008. Milestone C approval to proceed into Production and Deployment was given 11 June 2009 by USD (AT&L). Certification for entrance into Initial Operational Test & Evaluation was received on 06 Feb 2012. Full Rate Production Acquisition Strategy approved on 20 August 2012. Initial Operational Test & Evaluation concluded 1 October 2012. Successfully held a Defense Acquisition Board for Full Rate Production. Received a successful decision to enter into Full Rate Production on 01 March 2013. Initial Operational Capability achieved on 10 October 2014.
