### Project S40 — Army Integrated Air and Missile Defense

This funding line is directly aligned to the U.S. Army Air and Missile Defense (AMD) Modernization Priority. The Army Integrated Air and Missile Defense (AIAMD) program is a designated Major Defense Acquisition Program (MDAP), a critical component of the Army's AMD strategy, and is a top AMD Cross Functional Team modernization priority program. The funding in this PE provides for hardware upgrade of end items to include design engineering and development changes needed prior to implementation into the baseline. Funding in FY 2026 and FY 2027 also supports convergence of AMDPCS into the IBCS hardware baseline. In FY 2026, appropriate effort and funds were realigned to PE 0606118A, AIAMD Software Development & Integration to support entering into the Software Pathway. AIAMD is directly aligned to the U.S. Army Air and Missile Defense (AMD) Modernization Priority. The AIAMD program is a direct response to the U.S. Army AMD Concept and Operational and Organizational (O&O) Plan for the Future Force, the AIAMD System of Systems (SoS) Capabilities Development Document (CDD) and the AMD Task Force Concept of Operations (CONOPS) and a top Cross Functional Team Priority. The AIAMD Program is uniquely structured to enable the development of an overarching SoS/Integrated Fires capability with all participating Department of War (DoW) Air Defense Artillery (ADA) components functioning interdependently to provide total operational capabilities not achievable by the individual element systems. This funding will optimize effort to modernize air defense systems under an Integrated Fires architecture to manage and defend the battlespace in a joint environment against complex threats using the Integrated Battle Command System (IBCS) as the centerpiece. The AIAMD program achieves this objective by establishing the AIAMD SoS architecture and developing (1) the IAMD Battle Command Systems (IBCS) Engagement Operations Center (EOC) to provide the common Mission Command capability, (2) the Integrated Fire Control Relay capability for fire control connectivity and distributed operations, and (3) the common Plug and Fight (P&F) Kits to network-enable multiple sensor and weapon components including the IBCS EOC.

**Named R-3 performers** (share of this project's FY2027 R-3 total, so they need not reach 100%)**:** Northrop Grumman (71.8, 82%).

| Activity (R-2A) | FY2025 | FY2026 | FY2027 |

| Test and Evaluation - Beyond IOC Capability | 190.9 | — | — |
| IBCS Hardware Upgrades | — | 18.6 | 15.8 |
| IBCS/AMDPCS Hardware Convergence | — | 11.0 | 71.8 |

### Project SS1 — Remote Interceptor Guidance (RIG) 360 Dev and Int

This funding line is directly aligned to the U.S. Army Air and Missile Defense (AMD) Modernization Priority. The Army Integrated Air and Missile Defense (AIAMD) program is a designated Major Defense Acquisition Program (MDAP), a critical component of the Army's AMD strategy, and is a top AMD Cross Functional Team modernization priority program. Remote Interceptor Guidance 360 (RIG-360) is a software-defined, X-band missile communications device that provides full hemispherical, 360-degree in-flight communications with IAMD Composite Task Force interceptors including the PATRIOT Advanced Capability 3 (PAC-3) family of interceptors. The RIG-360 adds capability to the AIAMD architecture by unlocking the full kinematic potential of the PAC-3 family of interceptors providing full 360-degree coverage against attacking non-ballistic threats. The system expands the Warfighter's area of control and increases AMD effectiveness. RIG's 360-degree engagement capability leverages sensors integrated within the IBCS architecture and integrates an interceptor datalink device as a network component advancing IAMD goals of pairing any sensor with best shooter. The RIG-360 consists of two Major End Items, the Control Assembly and Array Assembly. The Control Assembly, in a rack mounted case, is the control node for the Array Assembly and serves as the Adaptation Kit (A-Kit) to the Integrated Fire Control Network. The rack mounted case provides outer ruggedness to environmental conditions with internal shock isolation, while allowing easy interchange of power supplies, server components, or other components as required within an industry standard rack assembly. The RIG-360 Array Assembly is a mast-mounted, X-band array of antennas that transmit and receive the interceptor radio frequency PAC-3 missile communication waveforms. FY 2027 Funds in the amount of $39.030 million supports completion of RIG 360 development and conduct of IOTE in support of a FY 2027 Milestone C decision.

**Named R-3 performers** (share of this project's FY2027 R-3 total, so they need not reach 100%)**:** Lockheed Martin (26.1, 67%).

| Activity (R-2A) | FY2025 | FY2026 | FY2027 |
|---|---|---|---|
| RIG-360 Development | 69.1 | 95.3 | 32.8 |
| Test and Evaluation | 4.2 | 18.6 | 6.2 |

> R-2A activities carry the prior, current and budget year only — no five-year plan. Coverage is partial, so count them, never total them.

## Where the FY2027 request goes

| Category | Share | $M |
|---|---|---|

## Mission & acquisition strategy

This funding line is directly aligned to the U.S. Army Air and Missile Defense (AMD) Modernization Priority. The Army Integrated Air and Missile Defense (AIAMD) program is a designated Major Defense Acquisition Program (MDAP), a critical component of the Army's AMD strategy, and is a top AMD Cross Functional Team modernization priority program. The funding in this PE provides for hardware upgrade of end items to include design engineering and development changes needed prior to implementation into the baseline. Funding in FY 2026 and FY 2027 also supports convergence of AMDPCS into the IBCS hardware baseline.

Beginning in Fiscal Year 2026, the AIAMD acquisition strategy will diverge into two separate funding paths. A new budget line, PE 0606118A, is being created specifically for the IBCS Software Acquisition Pathway. Consequently, the existing S40 line will pivot to focus exclusively on supporting the development, integration, and testing of IBCS Increment 2 and Increment 3 hardware components. This updated strategy merges the legacy AMDPCS and current IBCS capabilities into the new Increment 3 program. The first project in this program will combine the Engagement Operations Center (EOC) and the tent-based Integrated Collaborative Environment (ICE) into a single M1087A2 Expando Van.
