Multi-Domain Sensing System (MDSS) Adv Dev

The Multi-Domain Sensing System (MDSS) Advanced Development program, initiated in Fiscal Year 2022, aims to enhance the Army's capabilities in Aerial Intelligence, Surveillance, and Reconnaissance (A-ISR) through a layered approach. This initiative focuses on achieving Multi-Domain Operations (MDO) capable deep sensing by integrating various systems such as the High Accuracy Detection and Exploitation System (HADES) and the High Altitude Extended Range Long Endurance Intelligence Observation System (HELIOS). The program leverages emerging technologies like Artificial Intelligence/Machine Learning (AI/ML) for processing, automated target recognition, and resilient Joint All-Domain Command and Control (JADC2) compliant communications to improve operational efficiency.

The HADES Platform, Payloads/PED, and Integration project is a key component of the MDSS family. It provides advanced aerial intelligence sensing capabilities designed to address deep sensing needs against peer and near-peer adversaries across all phases of operations. The project emphasizes high mobility and long endurance through the collection of Communications Intelligence (COMINT), Electronics Intelligence (ELINT), and Synthetic Aperture Radar/Moving Target Indicator (SAR/MTI) data. Future upgrades will enable hosting of Electronic Warfare (EW), RF-enabled Cyber capabilities, and Launched Effects (LE).

In Fiscal Year 2025, the focus is on system-level prototyping of the HADES system. This effort supports the acquisition of prototype aircraft and payloads, as well as Non-Recurring Engineering (NRE) for design integration and testing. The overall effort for HADES Middle Tier of Acquisition spans from FY24 to FY27, ensuring continued development across future defense programs.

The MDSS Advanced Development program also includes efforts in architecture development to ensure end-to-end compatibility and sensor fusion. While no new funding is requested for Project BY9 in FY 2025, previous accomplishments include SAR/MTI development, SIGINT prototyping, and establishing a Secure Sensor System Integration Lab. These efforts are crucial for expanding sensor performance to address MDSS requirements effectively against near-peer threats.
