ARSR-4 Replacement - Hawaii

Abstract

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 for Air Traffic Control (ATC) and weather monitoring. The new system is designated the ARSR-4 Replacement Hawaii (ARSR4R-HI) Long Range Radar (LRR). It is a key component of the USAF's defense of Hawaii as a high priority mission for the DoD and supports NORAD/NORTHCOM and PACAF/INDOPACOM Deterrence Initiatives. The ARSR4R-HI program develops an integrated Homeland Defense surveillance against air cruise missiles while maintaining the ATC capability required by both the Federal Aviation Administration (FAA) and the Department of Defense (DoD). The ARSR4R-HI program is established to address 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 enhance current system capabilities to meet evolving needs for surveillance and tracking of modern aircraft and 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 effort will solidify the solution as 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 FY2024 effort includes integration efforts between the Air Force and FAA systems including architecture development, requirements documents completion, acquisition strategy development, site surveys, requests to industry to identify mature systems data/availability, industry demonstration efforts and development of Request for Proposal. The ARSR4R-HI consists of one ground based radar, tower, and ground based shelters, and other smaller Government Furnished Equipment (GFE) items. The FAA currently owns the site for the location of the installation. 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 FY22, $0.000M was expended for civilian pay expenses in this program element, and in FY23 $0.000M 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.
