Who gets it
No single contractor is published as this line's leader. 2 linked award records are listed below. This line's high-confidence links do not clear the floor for a published concentration index — at least 3 awards across 2 contractor families holding positive obligations, with positive net linked dollars. Why the crosswalk is partial.

The vertical scale does not start at zero: the baseline sits just below this program’s smallest year, so a low point on this line is not a small amount. Read the shape for direction and the grid below for the figures.

Asked vs spent: the PB2019 book requested $40.3M for FY2019; the PB2021 book reported $24.7M as actual total obligation authority — $15.6M below the request. 24.7 − 40.3 = -15.6 USD millions — the compact figures above are rounded for reading.

Description

Mission — Three Dimensional Expeditionary Long Range Radar

The Three-Dimensional Expeditionary Long-Range Radar (3DELRR) program develops the AN/TPY-4 system which is the designated replacement for the AN/TPS-75 radar. The AN/TPS-75 is an outdated and unsustainable system which was first fielded in the early 1970s. The 3DELRR system will be the United States Air Force's (USAF's) principal long-range, ground-based sensor for detecting, identifying, tracking, and reporting aerial tracks for the Joint Force Air Component Commander (JFACC). The 3DELRR system consists of the AN/TPY-4 radar and associated ground support equipment which includes Prime Movers, Generators, and other smaller mission support items. When fielded, the 3DELRR system will provide multiple benefits and increased capabilities to the USAF and the Joint Services, including: the ability to detect and track modern and emerging highly maneuverable, small radar cross-section airborne target; greater battlefield and battlespace awareness through a precise, real-time air picture of sufficient quality to control individual aircraft under a wide range of environmental and operational conditions; and increased reliability, operational availability, maintainability, transportability, survivability, and sustainability. FY 2026 funding will continue system capability development, which include development of electronic protection (EP) techniques, continued software fixes and Non-Recurring Engineering (NRE) costs. Additionally, FY 2026 funding will support continued test and evaluation activity, to include Initial Operational Test and Evaluation (IOT&E) of the system. 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 2025 $0.12 million was expended for civilian pay expenses in this program element, and in FY 2026 $0.17 million is forecasted for civilian pay expenses in this program element. This effort is in Budget Activity 4, Advanced Component Development and Prototypes (ACD&P), because efforts are necessary to evaluate integrated technologies, representative modes or prototype systems in a high fidelity and realistic operating environment.

Related awards

Award linkage is shown for 32 of 200 profiled companies — high- and medium-confidence USAspending matches, each row labeled; medium is the weaker evidence. why partial award coverage? →

Rows marked medium rest on evidence weaker than a program-level match, and of more than one kind. An account-based row, where the award drew from the same appropriation account as this program, is an association, not evidence that this program paid for the contract. Where the evidence is instead an FPDS acquisition-program tag or a subaward description, the program is established but which of its budget lines paid is not. An announcement link a recorded review did not leave standing is medium too. Only high rows rest on the contract naming this program with a recorded review upholding it and no recorded rejection or refutation applying.

Contractor concentration

No concentration index is published for this line. This line's high-confidence links do not clear the floor for a published concentration index — at least 3 awards across 2 contractor families holding positive obligations, with positive net linked dollars. An index below that floor is a fact about the sample, not about the market. Whatever further links this line carries are medium-confidence, and what each medium evidence path does and does not establish is set out in the methodology. Both bases are in the downloadable warehouse.

Lobbying mentions

No Senate LDA lobbying filing in the tracked data mentions this program element by code or alias.

Oversight

Department-level designation (not specific to this program)

GAO lists 5 high-risk areas for DOD as a whole. That designation covers the department, not Three Dimensional Long-Range Radar (3DELRR). No program-specific GAO finding for this line is in the ingested data. See the DOD oversight record.

Program dossier

No research dossier for this program — dossiers cover 50 of 1,938 programs, the largest fully J-book-detailed lines by FY2026 requested dollars. why no dossier here? →
