## Summary

This activity requests $19.2M in FY2027, 9.0% of project 2134, down 6.7% on FY2026. The R-2A exhibit describes it across FY2026–FY2027, including what the FY2027 money is planned to buy.

## What the FY2027 request buys

**FY2027 planned work.** - Complete development of a new High Frequency (HF) Direction Finding (DF) antenna and a Very/Ultra High Frequency (V/UHF) transmit antenna. - Complete development of updated antenna form factor and associated electronics for the AS-4683 L-Band antenna. - Complete the NewGRAD, a hemi broadband antenna required to meet Graywing mission requirements and providing SHF direction finding capability. - Continue integration with SEWIP, which will make Spectral interoperable with SEWIP to enable the systems to utilize each other's antennas, increasing the frequency range available to both systems. - Continue development of the AESA, an antenna providing simultaneous transmit and receive capability across a broad frequency range with high EIRP and gain-to-noise temperature. - Begin development against Special Signal Capabilities (SSC) and Spectral requirements to address gaps in future topside capabilities. - Conduct Operational Assessments for NewGRAD, HF/DF, V/UHF, High Gain, Narrow Band (HGNB), and Next Gen AS-4683 antennas.

**FY2026 to FY2027 change.** Advanced IW Antennas FY 2026 to FY 2027 decreased (-$1.382M) due to the completion of the development of updated antenna form factor and associated electronics for the AS-4683 L-Band antenna.

## Before the request year

**FY2026 plans — current year.** - Begin development of a new High Frequency (HF) Direction Finding (DF) antenna and a Very/Ultra High Frequency (V/UHF) transmit antenna. -Begin development of updated antenna form factor and associated electronics for the AS-4683 L-Band antenna. - Complete development of the High Gain, Narrow Band (HGNB) antenna, a satellite communications (SATCOM) antenna with simultaneous Ku/Ka dual-band capability. - Continue the NewGRAD, a hemi broadband antenna required to meet Graywing mission requirements and providing SHF direction finding capability. - Continue integration with SEWIP, which will make Spectral interoperable with SEWIP to enable the systems to utilize each other's antennas, increasing the frequency range available to both systems. - Continue development of the AESA, an antenna providing simultaneous transmit and receive capability across a broad frequency range with high EIRP and gain-to-noise temperature.

> Prior, current and budget year only — an R-2A activity carries no five-year plan. It sums exactly into its project in the request year and not necessarily in any other.
