HitchAI read

Project 650012 — TACMOR Development requests $96.0M in FY2027, 55% of the $174.0M requested for program element 0102417F — a restart: funded in FY2025, zeroed in FY2026, funded again now. 1 R-2A activity decomposes the request, 1 restarted this cycle. AFLCMC/ESG is the largest named R-3 performer at $96.0M, 100% of the project's FY2027 R-3 total.

Restart

This project was funded in FY2025 ($9.5M), zeroed in FY2026, and requests $96.0M again in FY2027. A restart has an incumbent and a new start does not; with a zero current year there is no percentage to quote, which is why it appears in no growth ranking.

What project 650012 buys

Efforts funded in this program focus on development, testing, and fielding, of a long-range early detection capability for airborne and surface targets of interest. Each line of effort acquires and fields a land based, high-frequency (HF) ionospheric, backscatter Over-the-Horizon RADAR (OTHR) for detection and tracking of airborne and surface targets over wide geographic areas. Fielding of this capability will enable detection, tracking and reporting of airborne and surface targets that may be obscured from conventional line of sight radar systems by the curvature of the earth. Tactical Multi-Mission Over the Horizon Radar(TACMOR) is a US Air Force remotely operated OTHR system being developed for deployment in the Republic of Palau (RoP). The system will provide enhanced Air Domain Awareness in key regions of USINDOPACOM's area of responsibility. This program may include necessary civilian pay expenses required to manage, execute, and deliver weapon system capability. The use of such program 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 0.000 million was expended for civilian pay expenses in this program, in FY 2026 0.111 million is forecasted for civilian pay expenses in this program element. TACMOR FY 2026 funds were allocated to - Program 012417F Project 674865 (budget authority 7). FY 2027-FY 2031 corrects the budget authority from 7 to 5 to appropriately reflect program efforts.

Prior years are actuals, the budget year is the request, and the outyears are the FYDP plan. Estimate types are colored and never summed into one figure. Projects carry the full five-year plan; the activities inside them stop at the budget year.

1 accomplishment / planned program

The R-2A exhibit — the only level of the budget that describes work that has not happened yet. Activities carry the prior, current and budget year only, no five-year plan. Each describes FY2027 work in enough detail to have its own page; the rest are shown here in full. Coverage is partial across the corpus, so count activities, never total them.

Named performers on project 650012

Performers named in the R-3 exhibit under this project. Share is of the project's whole FY2027 R-3 total — the same denominator the program-element split uses, so the two read on one scale and will not sum to 100% when unnamed or government work is in the mix. Budget-justification contract funding, not obligations.
