## Summary

Project DJ5 — Multi-Domain Artillery Cannon System (MDACS) requests $235.6M in FY2027, 100% of the $235.6M requested for program element 0604019A — a restart: funded in FY2025, zeroed in FY2026, funded again now. 1 R-2A activity decomposes the request, 1 restarted this cycle.

## Funding profile

## What project DJ5 buys

The Cannon Based Air Defense System (CBADS) mission is to defend Joint Force fixed and semi-fixed locations against attack by a broad spectrum of Unmanned Aerial Systems (UASs), Cruise Missiles (CMs), Fixed Wing (FW), Rotary Wing (RW), and other advanced air and missile threats and to complement existing air and missile defenses by operating in integrated or stand-alone operational scenarios. Additionally, CBADS may provide a future surface-to-surface long-range precision fires capability. CBADS is a rapid prototype and Integrated Air and Missile Defense (IAMD) Battle Command System (IBCS) integrated system consisting of a Multi-Domain Artillery Cannon (MDAC), Multi-Function Precision Radar (MFPR), Multi-Domain Battle Manager (MDBM), Hypervelocity Projectiles (HVP), and ammunition handling vehicles. CBADS will build onto the Army Integrated Air and Missile Defense (AIAMD) open systems architecture allowing seamless sensor and shooter connectivity for a layered defense with a mission command structure integrated into the IAMD Battle Command System (IBCS). CBADS will increase battlefield flexibility and raid capacity, resulting in increased AMD effectiveness and efficiency and reduced attrition of advanced interceptor missiles in the Army's inventory. The Army will leverage current Office of the Secretary of War (OSW) Strategic Capabilities Office (SCO) investments in the Hypervelocity Gun Weapon System (HGWS) to develop an Army design tailored to address Army requirements and assess CBADS at a Battery level in FY 2030. The prototype will inform an enduring capability requirement and decision in late FY 2026. The outcome of the decision review will be to determine whether to build a battery prototype for fielding or to initiate a traditional acquisition program for CBADS to meet the FY 2030 fielding date. .

**R-3 lines of work:** Management Services; Product Development; Test and Evaluation.

### Multi Domain Artillery Cannon System (MDACS) — RESTART

FY 2027 funds will be used to develop a baseline architecture, allocate subsystem requirements, and initiate CBAD prime item final designs. All remaining long lead material purchases will be placed on contract. Component and subsystem Contractor Verification Testing will be initiated. Software algorithm development will also be…
