The Department of Defense (DOD)’s Readiness and Environmental Protection Integration (REPI) Program fosters long-term, collaborative partnerships that enhance installation resilience and sustain military readiness across the Pacific. These partnerships help reduce mission threats and preserve key areas essential for testing, training, and operations by safeguarding natural and working lands surrounding installations. By enabling partners to protect and manage landscapes adjacent to military installations, REPI initiatives support DOD's role as a proactive land steward and a trusted partner to neighboring communities.
The Pacific region is a vital area for U.S. national defense, hosting numerous strategic installations and mission-critical infrastructure. As the Department continues to prioritize operations in the Pacific, REPI projects play an essential role in ensuring operational flexibility, resilient installations, and strong communities. In Fiscal Year (FY) 2024, the REPI Program committed over $33 million to support annual REPI and REPI Challenge projects across Hawai‘i, the Marianas Region, and Alaska. These investments are further amplified by substantial partner contributions and funding from other Federal programs.

Hawai‘i is a strategically vital location for DOD, supporting essential operations through the Pacific component commands of the Army, Navy, Air Force, Marine Corps, and Space Force. The state’s distinct geography and strategic importance necessitate coordinated, long-term efforts to maintain operational access and ensure installation readiness.
Through the REPI Program, DOD collaborates with partners to ensure continued mission effectiveness across the entire Pacific, protect critical landscapes, and enhance installation resilience.

The Mariana Archipelago—including Guam and the Commonwealth of the Northern Mariana Islands (CNMI)—supports critical Department of Defense missions through key installations such as Naval Base Guam, Andersen Air Force Base, Marine Corps Base
Camp Blaz, and the Military Lease Area on Tinian. These sites are essential to Joint Region Marianas (JRM) operations and regional force posture across the region. Installations in the region face increasing pressure from land use conflicts, habitat degradation, wildland fire threats, and expanding regulatory constraints. In response, the REPI Program provides a proactive tool to reduce operational risk and mitigate increased management costs. By partnering with territorial governments, Federal agencies, and local stakeholders, REPI projects in the Marianas help ensure mission continuity while fostering regional collaboration to address shared priority concerns. These efforts directly enhance installation resilience, reduce future operational constraints, and ensure long-term readiness in a strategically vital region.

Alaska is home to several DOD installations that support key National Defense priorities through the 2024 Arctic Defense Strategy. Among them is the world’s largest combined range complex, offering unmatched maneuver space, airspace, and training capabilities critical to U.S. force readiness in the Arctic and Pacific regions. Despite its strategic value, DOD operations in Alaska face increasing challenges from land development, infrastructure limitations, and rapidly changing environmental conditions that impact testing, training, and operations. Permafrost thaw, shifting habitats, and encroachment near mission areas pose growing risks to installation sustainment and force posture. To address these issues, the REPI Program is partnering with the Alaska Department of Natural Resources, Alaska Native corporations, and local and Federal agencies to strengthen wildfire resilience, secure compatible land use, and support habitat stability in key mission corridors. These efforts reduce operational risk, protect range access, and reinforce DOD’s long-term presence and flexibility in a rapidly evolving, strategic environment.

The REPI Challenge is a competition with dedicated funding for potential REPI partners to advance project outcomes outside DOD’s installations and ranges through large-scale, innovative actions in support of installation and community resilience. From its pilot project in Fiscal Year (FY) 2012, the REPI Program designed the REPI Challenge for partners and installations to cultivate innovative projects that harness creativity and protect critical testing and training capabilities.
For FY 2024 REPI Challenge Pacific Projects, the REPI Program contributed $9.4 million in funds, coupled with over $20.0 million in partner contributions to advance innovative projects that promote compatible land uses, enhance military installation resilience, and relieve current or anticipated environmental restrictions on military testing, training, or operations.
