### Project DJ6 — Effector Product Improvement

The Effector Product Improvement (DJ6) upgrades lower tier effectors (interceptors, fire control and M903 launching stations) to address operational lessons learned, enhancements to joint force interoperability and communications, and other system performance improvements to provide overmatch capability against the emerging threat. DJ6 PIP activities support enduring components of the system as legacy PATRIOT Ground Equipment is sunset with fielding of Integrated Battle Command System (IBCS). As components, software, and hardware improvements are developed, there is a continuing need for system level modeling, simulation, integration and testing. Modeling and Simulation (M&S) allow for performance assessment against specific threats in a manner that is not practical to demonstrate with live fire flight tests alone due to cost, target availability, and range constraints. Flight testing is periodically required for M&S validation as well as satisfying ATEC/DOTE requirements of segment improvements. FY 2027 funding will support test and development of improvements to currently fielded PATRIOT Family of Missiles (PFoM) and M903 launching stations to keep pace with current and emerging threats, support Guam Defense Systems specific efforts, and support Integrated Fires Control development and testing for the Army's Integrated Air and Missile Defense. -U.S. Government Program Management of DJ6 PIP efforts supporting system interceptors, launching stations, and associated materiel. -The AMD Effector Survivability effort enhances PAC-3 Missile segment effectiveness in a highly contested battlespace. Threat evolution and challenges include increased maneuverability, adversary quantities, electronic attack (EA) and use of hypersonics which continue to expand and complicate the ability to maintain defensive overmatch. The funding will deliver incremental software builds throughout the PAC-3 Missile segment, decreasing overall susceptibility and erosion of US capability to overmatch theater-level threats -PAC-3 Software Development Against Threat supports improved missile capability to counter current and emerging electronic attack threats. -Integrated PAC-3 Fire Control Development provides funding to support PAC-3 Fire Control and Link on ELES (LoE) development for integration with IBCS to enable Army Integrated Air and Missile Defense Modernization.

**Named R-3 performers** (share of this project's FY2027 R-3 total, so they need not reach 100%)**:** RSA, AL (29.3, 18%), RTX / Raytheon (17.7, 11%), RDEC and OGAs (10.7, 6.6%).

### Project DV8 — Patriot Product Improvement

The PATRIOT system includes a family of hardware, software, interceptors (PAC-2, Guidance Enhanced Missiles, PAC-3 and PAC-3 Missile Segment Enhancement) and Ground Support Equipment. PATRIOT system components (interceptors, launcher, and radar) are integrated with current force PATRIOT and Army Integrated Air and Missile Defense (IAMD) components, including IBCS. As PATRIOT system components software and hardware improvements are developed, there is a continuing need for system level modeling, simulation, integration and testing. Modeling and Simulation (M&S) allow for performance assessment against specific threats in a manner that is not practical to demonstrate with live fire flight tests alone due to cost, target availability, and range constraints. Flight testing is periodically required for M&S validation as well as satisfying ATEC/DOTE requirements of segment improvements. The FY 2027 funding in the amount of $57.640 Million supports the following: -PATRIOT system components software and hardware improvements for threat evolution: Performs necessary analysis and development efforts to maintain PATRIOT system (interceptors, ground support equipment, and current radar) effectiveness against evolving threat technologies and capabilities, support convergence with the IBCS, and complete PATRIOT Component Software Builds (PCSB). This effort identifies evolving threats and threat characteristics that present a challenge to PATRIOT's current capabilities and develops initial concepts to maintain system effectiveness including detection, tracking, discrimination, and engagement relative to these threats. Additionally, evolving threat information is used to develop, integrate, and assess evolving lethality models in high-fidelity interceptor simulations supporting system level assessment of hit-to-kill and warhead interceptor performance. -Advanced Electronic Counter Measures (AECM): This task investigates the implications of advanced technology Digital Radio Frequency Memory available on airborne platforms that enables new ECM techniques which could adversely degrade Air and Missile Defense System effectiveness. AECM efforts support PATRIOT system interceptors, ground support equipment, and current radar.

## Mission & acquisition strategy

The PATRIOT system includes a family of hardware, software, interceptors (PAC-2, Guidance Enhanced Missiles, PAC-3 and PAC-3 Missile Segment Enhancement) and Ground Support Equipment. PATRIOT system components (interceptors, launcher, and radar) are integrated with current force PATRIOT and Army Integrated Air and Missile Defense (IAMD) components, including IBCS. As PATRIOT system components software and hardware improvements are developed, there is a continuing need for system level modeling, simulation, integration and testing.

The design objective of Lower Tier Interceptors is to provide effectors capable of modification to cope with continuing threat evolution. The DJ6 PATRIOT Product Improvement Program (PIP) funds are utilized to minimize technological risks and provide means of enhancing effector capability to address new and emerging threats through planned upgrades of deployed systems. The DJ6 PIP Program upgrades lower tier effectors (interceptors and M903 launching stations) to address operational lessons learned, enhancements to joint force interoperability and communications, and other system performance improvements to provide overmatch capability against the emerging threat.
