Budget Trajectory

The program's 3 summary figures for FY24 to FY26, 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	$27.8M
FY25	$32.0M
FY26	$17.2M

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

5 fiscal years of this program as published (FY2022–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 falls 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	FY26
Actuals	$79.8M	$72.2M	$27.8M
Enacted	–	$78.2M	$27.8M	$32.0M

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

Description

Description — Aegis BMD Hardware and Software

Decrease from fiscal year (FY) 2025 to FY 2026 reflects the reduction of Aegis BL 9.C2 (BMD 5.1) inline hardware procurement and Diminishing Manufacturing Source (DMS). The Aegis BMD element of the Missile Defense System capitalizes upon and evolves from the existing United States (U.S.) Navy Aegis Weapons System (AWS) and Standard Missile (SM) infrastructures. This budget line provides funding for the procurement, installation, fielding, and deployment of integrated Aegis BMD combat system to operational ships and sites for homeland and regional defense. Aegis BMD combat system 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, and shorter range missiles in the terminal phase of flight. The Aegis BMD combat system also provides a Long Range Surveillance and Track capability to the Missile Defense System in support of early detection of BMD threats to the homeland. The Sea-Based mission is to deliver an enduring, operationally effective and supportable BMD capability to defend the nation, deployed forces, friends and allies, and to increase this capability by delivering evolutionary improvements as part of Ballistic Missile Defense System upgrades. Upgrades to both the AWS and the SM-3 configuration provides effective and supportable defensive capability against longer range and more sophisticated threats, and an enduring Aegis Ashore defensive capability. The 4.x to Baseline 5.4.1 (BMD 4.1.3) upgrade is a joint effort with the U.S. Navy. Updates planned for 21 Flight I/II Destroyers. Capabilities delivered include discrimination and mission planner improvements, increased threat set, Sea Based Terminal Increment II Capability Upgrade, hypersonic tracking and reporting, Electronic Attack/Electronic Protect improvements and other warfighter enhancements. The 5.x upgrade adds capability and capacity to achieve the European Phased Adaptive Approach (EPAA) Phase III requirements. Hardware and software updates, 5.x shipsets provide warfighter improvements implemented through Combat System upgrades to meet emerging threats. The procurement and fielding of new BMD components impacted by DMS will allow for the continued production of 5.x and 4.x in support of EPAA Phase II and III requirements. A shipset consists of the procurement of cabinets, cabling, equipment, and other material required to support a single shipboard installation of the appropriate BMD baseline. Shipsets are not useable military end items; therefore, P-40 procurement quantities exclude shipsets, installation services, and DMS in accordance with the Department of Defense Financial Management Regulation.
