Budget Trajectory

The program's 2 summary figures for FY24 to FY25, plotted in fiscal-year order so the direction of travel is readable at a glance: this line ends lower 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.
Fiscal year	Amount
FY24	$601.5M
FY25	$195.0M

All series figures: P-1 TOA · PB2026

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

4 fiscal years of this program as published (FY2022–FY2025): 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	FY22	FY23	FY24	FY25
Actuals	$352.1M	$402.2M	$601.5M
Enacted	–	$402.2M	$374.8M	$195.0M
Request	–	–	$374.8M	$85.0M

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

Asked vs spent: the PB2024 book requested $374.8M for FY2024; the PB2026 book reported $601.5M as actual total obligation authority — $226.8M above the request. 601.51 − 374.76 = 226.75 USD millions — the compact figures above are rounded for reading.

Description

Description — AEGIS BMD

Decrease from Fiscal Year (FY) 2025 to FY 2026 reflects the termination of Standard Missile-3 (SM-3) Block IB new production as a result in a shift in Department priorities. After FY 2024, the Department will discontinue the SM-3 Block IB procurements in favor of SM-3 Block IIA, and continue to evolve the Block IIA missile within the Aegis Weapons System. FY 2025 provides $110 million Congressional Plus Up for procurement of six (6) SM-3 Block IBs and $85 million for critical investment spares to support repair and recertification of fielded SM-3 Block IB All-Up Rounds (AURs) in anticipation of supply chain attrition following termination of new production. In accordance with the Consolidated Appropriations Act 2020, SM-3 Block IIA was transferred to MD14 from MD09 in FY 2020 and beyond; this exhibit includes FY 2018 and FY 2019 SM-3 Block IIA funding. FY 2023 quantities are the final year of the FY 2019 through FY 2023 Multi-Year Procurement of 198 AURs that resulted in a reduced unit cost due to economy of scale. FY 2024 and FY 2025 are single year procurements resulting in a higher unit cost due to lower quantities and loss of economy of scale. Procurement Quantity" and "Flyaway Unit Cost" above represent SM-3 Block IB missiles only, but the Net Procurement and Gross Weapon System costs includes all hardware and support costs including canisters, production engineering, obsolescence and system engineering, which are detailed in separate P-5s. The Flyaway Unit Cost is baseline only. Prior Year procurement of 71 SM-3 Block IAs are not included. The Aegis-Based Weapon Systems mission is to deliver an operationally effective and supportable Ballistic Missile Defense (BMD) capability to defend the nation, deployed forces, and allies. Aegis BMD aims to increase this capability by delivering evolutionary improvements as part of Missile Defense System upgrades. Sea-Based Weapon Systems provides a forward-deployable, mobile capability to detect and track ballistic missiles of all ranges, and the ability to destroy Short-Range Ballistic Missiles, Medium-Range Ballistic Missiles, and Intermediate-Range Ballistic Missiles in the midcourse phase of flight. Upgrades to both the Aegis BMD Weapon System and SM-3 configuration enable Aegis BMD to provide an effective, supportable, and defensive capability against longer range, more sophisticated threats and an enduring Aegis Ashore defensive capability. The SM-3 Block IB improves Aegis-Based Weapon Systems ability to expand the BMD battlespace, engage longer range, more sophisticated ballistic missiles that may deploy countermeasures and launch in larger raid sizes. The SM-3 Block IB Kinetic Warhead's two color infrared seeker and advanced signal processor provides a real-time discrimination and characterization capability while improving sensitivity for longer range targets.

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 Aegis BMD — no program-specific GAO finding for this line is in the ingested data. See the DOD oversight record.
