Roll-up of 5 projects. Projects are the summable leaves — the PE total is their sum, never added to it.
For fiscal year 2027, the U.S. Army is requesting $125.3M for Electronic Warfare Development under RDT&E program element 0304270A, down 1.4% from FY2026. In the FY2027 defense authorization, House approps moved to cut it to $95.3M.

SIGINT is funded on 4 lines across 2 appropriations
This page shows $2.2M of SIGINT, 2.4% of the program's $91.6M FY2027 request. The rest is appropriated elsewhere.

Program detail
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).

What project A99 buys
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.
