### Project CK3 — TLS Echelon Above Brigade (EAB)

Details provided under separate cover.

### Project FJ5 — Terrestrial Layer System

The total cost of the Terrestrial Layer System (TLS) Brigade Combat Team (BCT) Manpack Middle Tier of Acquisition effort is $455.9 million, including RDT&E and Procurement of prototype units. The TLS BCT Manpack program is funded across the Future Years Defense Program. Details provided under separate cover.

### Project A9B — EW-SIGINT Technology-Innovation Pipeline

Details provided under separate cover.

| NAVWAR and EW High Altitude Technology Development | — | 2.5 | — |

> 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 A9A — Theater SIGINT System (TSIGS)

Details provided under separate cover.

### Project A99 — Electronic Warfare Technology Maturation

Project A99 is an EW Technology maturation line is for technology transition, maturation and risk reduction efforts for prototyping and integration of system components for Signals Intelligence (SIGINT)/Electronic Warfare Support (ES), Electronic Attack (EA) and Radio Frequency (RF) enabled Cyber to provide or enhance RF sensors, effectors, and operational awareness for for EW & SIGINT capabilities. Transitions critical technology from Army labs, other government agencies, industry or academia to address critical technical challenges and accelerates new capabilities against emerging requirements. Allows for technology transfer, transition, prototyping of generic exploitation capabilities, lab test and integration into Programs from Army Labs, Academia, and Industry to provide responsive and agile Electronic Warfare & SIGINT capabilities that are required to keep pace with near peer threat and modern technologies such as: Artificial Intelligence/Machine Learning (AI/ML), Disposable payloads, Tethered payloads, Uncrewed Payloads, Load Setting Techniques, Cooperative EW, Obscuration, Deep Sensing and effecting, Weapons Pairing, Common Operating Pictures, Counter Surveillance, Indications and Warning, Electromagnetic Footprint recognition, etc.

## Mission & acquisition strategy

FY 2027 funding in the amount of $125.301 million supports this Program Element encompassing engineering and manufacturing development for tactical Electromagnetic Warfare (EW) terrestrial (ground) employment applications. The systems under this program provide the Army with the capability to detect, identify, locate, collect/process, report, and engage (disrupt, degrade or deny) hostile forces to prevent their effective use of communications & non-communications networks, counter-mortar/counter-battery radars, surveillance radars, electronically fused munitions and other enemy threats using the Electro-Magnetic Spectrum (EMS).
