Mission — ARSR-4 Replacement - Hawaii source

This budget line item funds the replacement of the current Hawaii Air Route Surveillance Radar Version 4 (ARSR-4) to include prototype development, test, site preparation, and installation. The replacement radar will address DoD capability gaps driven by new threats and provide dual use for Hawaii Air Traffic Control (ATC). The new system is designated the ARSR-4 Replacement Hawaii (ARSR4R-HI) Long Range Radar (LRR). It is a key component of the integrated Homeland Defense capability for the defense of Hawaii and a high priority mission for Pacific Air Forces and the United States Indo-Pacific Command. The ARSR4R-HI program addresses the following surveillance shortfalls: 1. Lack of surveillance capabilities to meet today's mission needs such as inability to characterize and classify targets or cover all required airspace. 2. Inability to scale and update capabilities to pace evolving threats. 3. Obsolescence associated with 1980s era ARSR-4 equipment and infrastructure leading to excessive sustainment, operations, and maintenance costs. To address these surveillance shortfalls, development of the ARSR4R-HI system will consist of improved detection performance for modern air threats, mitigate new interference sources, and utilize state of the art surveillance technologies and processing capabilities. The ARSR4R-HI solution is based on a non-rotating, multi-panel, phased array radar system which provides persistent surveillance with improved accuracy and detection performance supporting an advanced engagement sequence to counter modern threats with target cueing and fire control quality data. The ARSR4R-HI components include a ground based surveillance radar, radar dome, associated shelters, and other smaller Government Furnished Equipment (GFE) items. The DoD currently owns the site for the location of the installation and the FAA leases the site. The ARSR4R-HI program includes the award of two Rapid Prototype Development capability demonstration contracts (Phase I) followed by down-select (Phase II) to a single vendor for Non-Recurring Engineering (NRE), mature prototype delivery, installation, interface with Command and Control (C2) nodes, and test of the new radar at the Mt. Ka'ala site. The FY 2026 cost of the ARSR4R-HI Middle Tier of Acquisition effort is reflected in the budget request, including RDT&E and procurement of prototype units. The Department will certify FYDP funding in a future budget submission. The FY 2026 request for ARSR4R-HI includes 17.4 million of discretionary and 150.0 million of mandatory (reconciliation) funds for a total of 167.4 million. The mandatory (150.0 million) funds, along with 45.7 million of FY 2025 funding, enable award of the Phase II prototype system contract. Further information for this reconciliation request is provided in Section 20003 of the Reconciliation Exhibit. The FY 2026 request was reduced by 0.136 million for Advisory and Assistance Services to promote efficiencies and advance the policies of the Administration in alignment with Executive Order 14222, "Implementing the President's Department of Government Efficiency Cost Efficiency Initiative." This program element may include necessary civilian pay expenses required to manage, execute, and deliver weapon system capability. The use of such programs funds would be in addition to the civilian pay expenses budgeted in program element 0605827F, 0605828F, 0605829F, 0605831F, 0605832F, 0605833F, 0605898F, 0606398F. In FY 2024, 0.599 million was expended for civilian pay expenses in this program element, and in FY 2025 1.955 million is forecasted for civilian pay expenses in this program element. This program is in Budget Activity 7, Operational System Development because this budget activity includes development efforts to upgrade systems that have been fielded or have received approval for full rate production and anticipate production funding in the current or subsequent fiscal year.
