## Summary

Project 3051 — E-2D Adv Hawkeye requests $390.3M in FY2027, 100% of the $390.3M requested for program element 0604234N, up 11% on FY2026. 4 R-2A activities decompose the request. Northrop Grumman is the largest named R-3 performer at $146.7M, 38% of the project's FY2027 R-3 total.

**Markets:** Maritime & ISR Aircraft — matched on the project title only, and no market size is quoted.

## What project 3051 buys

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.
