Tank and Medium Caliber Ammunition

The Extended Range Artillery Munitions (ERAM) project supports the development of a 155mm system of systems that includes projectile, propellant, primer, fuse, and fuse setter which will deliver lethality and range overmatch in 155mm artillery weapon systems at more than double the current range from legacy artillery cannons and will be compatible with future 155mm artillery systems in contested Global Positioning System (GPS) environments and suboptimal atmospheric conditions. The ERAM development effort is part of an organic Long Range Precision Fires capability, which will provide overmatching cannon artillery range capability at both Tactical and operational Fires range by shaping the nature of the close fight through seeking moving and imprecisely located targets at extended ranges, increase range capability of the current 39 caliber cannon fleet and will also be compatible with future 52 caliber and above artillery weapon systems. Fiscal Year (FY) 2027 funding will support technology maturation and risk reduction of key system and subsystems improvements in performance in difficult use cases (such as GPS contested environments and suboptimal atmospheric conditions), and integration of the tactical warhead and seeker culminating in a series of Design Verification Testing (DVT) to achieve Technology Readiness Level (TRL) six (6) maturity.

The Assured Precision Weapons and Munitions (APWM) - FA5 Project is focused on advanced risk mitigation, technology integration, expedited prototyping, and product support to rapidly identify, evaluate, mature, test, and demonstrate various assured precision related prototype technologies in munitions and munition resilient support and survivability components and subsystems within a complex environment with the overarching goal of solving tough operational problems and addressing critical capability gaps. The APWM project reinforces the Secretary of War's Acquisition Transformation Strategy, and the Army Transformation Initiative (ATI) major lines of effort through fast technology development and prototyping, which increases lethality and ensures future combat overmatch success of the Joint force against peer/near-peer adversaries and the China pacing threat. This project also aims to improve performance and affordability of Army and Joint capability portfolios via Joint Lethality (JL) Positioning, Navigation and Timing (PNT), Navigation Warfare (NavWar), and Army M-code Global Positioning System (GPS) coordinated efforts and integration of innovative industry contributions. The APWM project directly supports the top Army and Joint force modernization priorities in support of the NDS and multiple Public Law (PL) related congressional imperatives. Funding will support engagement by munition PNT and NavWar related Lethality experts in the development, evaluation, and technology delivery activities of the M-code GPS as well as the Army's continuous adaptation of PNT, NavWar, and Electronic Warfare (EW) enabled capabilities to achieve accurate extended range and hypersonic lethality, increase warfighter survivability, maximizing precision munition stowed kills, and countering Anti-Access/Area Denial (A2/AD) threats. The APWM project enables component and subsystem architecture input essential for precision munitions and other such lethality delivery mechanisms operating in a complex EW threat environments, M-code GPS and technology integration and evaluation (including verifying and validating this capability for future Joint precision munitions), and maturation of alternative PNT and EW/NavWar related technologies, components, payloads, and solutions.

DN7: The Mobile-Long Range Precision Strike Missile (M-LRPSM) is an approved Directed Requirement (DR). It must defeat Tier 1 thru Tier 3 Armor (stationary & defilade) Troops, Field Fortifications & Urban structures, and achieve a range of greater than 25 KM. It will be transportable by existing Infantry Brigade Combat Teams (IBCT) Light Tactical Vehicle platforms. It has the ability to adjust the missile flight, retarget, and abort, and have multiple missiles launch capability. It must be survivable and resilient in denied and degraded environments. The FY 2027 funding will provide system prototypes for candidate vendors and their participation in a flyoff demonstration. Following a down select one vendor at the end of the flyoff demonstration, FY 2027 funding will procure system prototypes to be used to conduct required testing to receive an Urgent Material Release.

The 155 millimeter (mm) High Explosive Conventional Artillery Modernization will develop common artillery projectiles capable of accurate delivery of multiple payloads to provide US Army's Field Artillery units with lethal and nonlethal area effects at ranges necessary to disable and destroy a broad set of targets within multiple threat formations. The Modular Artillery for Combat Effectiveness (MACE) line of effort will develop lethal area effects. The Extended Range (ER) Cargo line of effort will develop lethal and non-lethal areas effects at the longer ranges necessary to enable transformation in contact. This effort is executing an evolutionary approach to ensure a common projectile can support multiple cargo capabilities, including but not limited to lethal, Radio Frequency (RF) obscuration, visible obscuration, Intelligence, Surveillance, and Reconnaissance (ISR), Infra-red (IR) illumination, visible illumination, electronic attack, Terrain Shaping Obstacles, and future cargo capabilities. Fiscal Year (FY) 2027 funding will support the Technology Readiness Level (TRL) 6 demonstration, down-selection, contract award for system development, and technical assessment in support of the Army's Field Artillery modernization objectives.

The 155mm Artillery Propulsion Modernization (Advanced Component Development) project supports the United States Army's Field Artillery modernization objectives by developing and maturing three propulsion system components: (1) modular charge that achieves minimum to intermediate ranges, (2) supercharge that achieves maximum range, and (3) percussion primer that initiates both the modular and supercharges. Development efforts also include the design of packaging solutions required for protection during transportation and long-term storage, digital engineering, test measurement devices and modeling and simulation tools. Design emphasis will shift from Joint Ballistic Memorandum of Understanding (JBMOU) compatibility to down selected Mobile Tactical Cannon (MTC) that maximizes interoperability with foreign allies, ensuring that the components support manufacturability within the National Technology and Industrial Base (NTIB). Fiscal Year (FY) 2027 funding will support continued prototyping and testing of propelling charges, combustible cases, additives, and ignition components to advance technologies that improve propellant effectiveness, extend cannon life, enhance primer and charge ignition performance, optimize system-level handling, rates of fire, and overall propulsion suitability and survivability.

This project supports the future force by improving the distribution, management, reliability, and survivability of ammunition through the advanced development, integration, and demonstration of logistics system enablers in alignment with Transformation In Contact and Deliberate Transformation. These enablers will improve the resiliency, efficiency and effectiveness of ammunition operations, to include retrograde, while reducing the logistics footprint on the battlefield. Technology areas addressed include handling, distribution, management (strategic and tactical), prognostics, diagnostics, asset visibility, explosives safety, autonomy friendly packaging, and palletization. The efficient deployment and sustainment of reliable ammunition is vital to success on the battlefield. This project enhances the operational effectiveness of the ammunition logistics system to ensure the distribution of reliable ammunition to the Warfighter.

Long Range Precision Munition (LRPM) is the lethal variant of the Launched Effects (LE) Family of Systems which provide a range of capabilities through variations of platforms, payloads, and mission systems. LE provides tactical and operational flexibility through collaboration of heterogeneous groups of LE launched from multiple domains (land and air) in conjunction with other manned platforms, C2, unmanned systems, and sensors throughout the operational environment. The ability to interoperate and coordinate with other LE systems at long ranges and adapt to changing threats is a core concept of the Launched Effects Abbreviated Capability Development Document validated in June 2024. Primary target set for LRPM is Integrated Air Defense Systems. LRPM will provide Army Aviation and Ground Forces with a precise long range munition system to rapidly respond in a combat environment to improve the lethality and stand-off of Warfighters and aviation platforms in an Anti-Access Area Denial (A2AD) and positioning, navigation, and timing (PNT) denied environment. Project CD8 - Long Range Precision Munition (LRPM) was transferred to PE 0605345A/Project A56 in FY 2026.
