Hypersonics EMD

The Hypersonics EMD (Engineering and Manufacturing Development) program, as detailed in Program Element PE 0605232A, is a key Army initiative focused on advancing hypersonic weapon capabilities to address both near-term and mid-term threats. This program is directly aligned with the Army's Long Range Precision Fires modernization priority and is designed to provide the Army with the ability to defeat Anti Access/Area Denial (A2/AD) systems, suppress adversary long-range fires, and engage high-value, time-critical targets. The program is executed in close collaboration with the Navy, particularly in the development and testing of the Long Range Hypersonic Weapon (LRHW) system.

The HX2: Hypersonic Weapon (LRHW) line item encompasses the development, integration, and fielding of the LRHW system. The LRHW consists of several major components: the All Up Round plus Canister (AUR+C), which integrates the Common Hypersonic Glide Body (CHGB) and the Navy's 34.5-inch booster; the Battery Operations Center (BOC) for command and control; and the Transporter Erector Launcher (TEL). Each LRHW battery is structured to include eight AUR+Cs, one BOC, and four TELs, with each TEL capable of carrying two AUR+Cs. The system leverages the Advanced Field Artillery Tactical Data System (AFATDS) for command and control, utilizing a modified version to support hypersonic operations.

The All Up Round and Canister (AUR+C) budget line supports technology development, hardware procurement, integration, assembly, testing, and delivery of the AUR+C units. Funding is allocated for the delivery of inert training canisters, tactical rounds, reload rounds, and test/training/certification rounds for Joint Flight Campaign (JFC) events. The program also funds spare components and assemblies to support the LRHW's life cycle sustainment, ensuring readiness and reliability of the deployed batteries.

The Common Hypersonic Glide Body (CHGB) line item focuses on the development and production of the CHGB and its Thermal Protection System (TPS). Funding continues the delivery of CHGBs for integration into AUR+C assemblies, supports further development and demonstration of system components, and enhances training in accordance with the system training plan. The CHGB is provided as Government Furnished Equipment to the Navy's Conventional Prompt Strike program, highlighting the joint nature of this hypersonic initiative.

The Ground Support Equipment (GSE) line item provides for the planning, integration, and modernization of LRHW GSE, including operator and maintainer training devices and simulations. Funding supports the continued development and qualification testing of GSE, iterative improvements based on evolving requirements, and the implementation of corrective actions identified during testing. The GSE is critical for ensuring operational effectiveness and survivability of the LRHW batteries in field conditions.

The Test and Evaluation line item funds the planning, execution, and analysis of Joint Flight Campaigns (JFC) and Army operational and developmental tests. Funding supports the JFC-6 campaign, which serves as the operational demonstration required for Middle Tier of Acquisition Rapid Fielding programs, as well as qualification testing for Army GSE. This includes climatic, electromagnetic, and cybersecurity testing to validate system performance and readiness for operational deployment.

The System Engineering/Program Management line item covers government program management office support, engineering analysis, logistics assessments, and software maintenance necessary for RDT&E efforts. Funding reflects increased requirements for engineering and programmatic support related to technology insertions and operational testing. The acquisition strategy involves transitioning management from the Rapid Capabilities and Critical Technologies Office (RCCTO) to the Program Executive Office, Missiles and Space, following successful system qualification. The Hypersonics EMD program is structured to incrementally deliver enhanced hypersonic capabilities, maintain technological overmatch, and ensure the Army's ability to respond to evolving threats.
