Two official figures, one label— reconciled below

Fiscal Receipts uses P-1/R-1 workbook total obligation authority (TOA) as the headline figure sitewide. The workbook TOA includes budget rows that the R-2/P-40 J-book program line excludes — advance procurement in an ordinary year, and in FY2026 the one-time reconciliation appropriation as well. Each row below names the one it is. How the two bases relate →

FY26 Request · $168.3M TOA − $33.3M J-book line = 135.0M (168.3 − 33.3 = 135.0) — $135.0M of one-time FY2026 reconciliation money accounts for this gap — not advance procurement

Figures in the sentence are rounded for reading; the parenthesised arithmetic is the same subtraction in USD millions, at the precision where it closes.

Budget trajectory

The program's 3 summary figures for FY24 to FY26, plotted in fiscal-year order: this line ends higher than it starts. The points are the summary cards above, not a separate derivation; the table beside the chart carries each figure with its own citation.

Budget trajectory: one row per fiscal year, carrying the summary figure the sparkline plots. Every figure opens its own citation.

Decade view

P-1/R-1 workbook TOA basis, shown compact in $B/$M (the workbook records USD thousands); each figure cites its own President's Budget edition

7 fiscal years of this program as published (FY2020–FY2026): a line through the actuals (filled dots), with the enacted (hollow circles) and request (diamonds) markers each edition reported. Read it for direction, not for precision — this program's actuals line rises across the span. The grid below is the same data as text, one cited figure per cell.

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.

● actuals (line) · ○ enacted · ◇ request — gaps are editions the program is absent from, never interpolated.

Decade series values by fiscal year and President's Budget edition: one row per series (actuals, enacted, request), one column per fiscal year. Every figure opens its own citation.
Series	FY20	FY21	FY22	FY23	FY24	FY25	FY26
Actuals	$0	$14.5M	$48.3M	$48.2M	$48.3M
Enacted	–	$15.0M	$50.0M	$50.0M	$30.0M	$40.1M
Request	–	–	$0	$0	$30.0M	$30.1M	$168.3M

blank = series not published for this year; – = absent from that edition.

Asked vs spent: the PB2022 book requested $0 for FY2022; the PB2024 book reported $48.3M as actual total obligation authority — $48.3M above the request. 48.3 − 0.0 = 48.3 USD millions — the compact figures above are rounded for reading.

Description

Mission — Tactically Responsive Space (TacRS)

Tactically Responsive Space (TacRS) rapidly integrates and deploys space-based end-to-end capabilities in response to Combatant Commander (CCMD) urgent needs for power projection and characterization. TacRS missions will be capable of entering operations and generating effects on tactically relevant timelines. The near-term focus of TacRS is to establish these foundational concepts enabling the Space Force to establish the necessary capabilities, processes, concept of operations, and tactics, techniques and procedures to enable a rapid response. In FY 2026, funding will be used to finalize an early operational Space Domain Awareness (SDA) capability that will involve a rapid call-up, launch, and space vehicle operations. In addition, funding will be used to develop the maneuverable, prepositioned SDA TacRS missions. Furthermore, funding will be used to support follow-on SDA operational missions requiring both rapid launch and maneuverable, prepositioned capabilities. Finally, funding will be used to mature new TacRS concepts including, but not limited to, the ability to quickly utilize commercial capabilities. The FY 2026 request for TacRS includes $33,282 thousands of discretionary and $135,000 thousands of mandatory (reconciliation) for a total of $168,282 thousands. The mandatory funds additional TacRS space and launch vehicles in FY 2026. Further information for this reconciliation request is provided in Section 20009 (INDOPACOM Capabilities) of the Reconciliation Exhibit. This program element may include necessary civilian pay expenses required to manage, execute, and deliver Tactically Responsive Space weapon system capability. The use of such program funds would be in addition to the civilian pay expenses budgeted in program elements 1206392SF and 1206398SF. 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.

Justification

Accomplishments & Planned Programs (1)

TacRS Initial Operations and Continuous Capability Development

TacRS will leverage rapid, agile, and end-to-end acquisition processes to quickly evolve the design of future TacRS missions. This approach will enable timely integration and readiness for launch call-up, Combatant Commander (CCMD) tasking, and procurement of capabilities based on current threats and priorities.
