## 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.

**R-3 lines of work:** Product Development; Support; Management Services.

Congressional marks, the R-2 mission description and acquisition strategy, the industry vs government split of the whole request, and related program elements are recorded at **program-element** grain — an NDAA mark lands on a PE, never on a project.
