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 · $57.9M TOA − $0 J-book line (a zero-dollar XML line) = 57.9M (57.9 − 0.0 = 57.9) — $57.9M 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.

8 fiscal years of this program as published (FY2019–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.

Description

Mission — (U)LARGE UNMANNED SURFACE VESSELS (LUSVs)

This Program Element provides resources for Unmanned Surface Vessels, which play a key role in the Navy's Future Surface Combatant Force (FSCF). This Program Element also provides resources for the Prototype vessels that are being operated under PMS 406 for technology maturation and risk reductions efforts. USVs will provide affordable, high endurance ships able to accommodate various payloads for unmanned missions and augment the Navy's manned surface force. LUSVs will be capable of autonomous operation, with operators in-the-loop to control the combat system. USV Command and Control (C2) will be maintained via an afloat element (i.e., embarked on a United States Navy (USN) combatant/other assigned afloat asset) or via an ashore element (C2 station ashore). USVs are a key enabler of the Navy's Distributed Maritime Operations (DMO) concept, which includes being able to forward deploy and team with individual manned combatants or augment battle groups. USVs will complement the Navy's manned combatant force by delivering increased readiness, capability and needed capacity at lower procurement and sustainment costs and reduced risk to sailors. While unmanned surface vehicles are new additions to the fleet units, USVs will combine robust and proven commercial vessel specifications with existing military payloads to rapidly and affordably expand the capacity and capability of the surface fleet. USV development is supported by research and development prototype vessels intended to demonstrate successful integration of government furnished Command, Control, Communications, Computers and Intelligence (C4I), combat systems, and the reliability of automated hull, mechanical, and electrical (HM&E) systems. The program leverages years of investment and full scale demonstration efforts in autonomy, endurance, command and control, payloads and testing from the Defense Advanced research Projects Agency (DARPA) Anti-Submarine Warfare Continuous Trail Unmanned Vessel (ACTUV), Office of Naval Research (ONR) Medium Displacement Unmanned Surface Vehicle (MDUSV)/Sea Hunter (FY 2017 to FY 2021), and Office of the Secretary of Defense Strategic Capabilities Office (OSD- SCO) Ghost Fleet Overlord USV experimentation effort (FY 2018 - FY 2021). The combination of fleet-ready C2 solutions developed by the Ghost Fleet Overlord program and man-in-the-loop or man-on-the-loop control will reduce the risk of fleet integration of unmanned surface vehicles and allow autonomy and payload technologies to develop in parallel with fielding vehicles with standardized interfaces.

Mission — Large Unmanned Surface Vessel (LUSV)

The major goal for FY26 is conducting a prototyping phase in order to work with industry on reducing risk in preparation for serial production of vessels. This phase will focus on industry designs to ensure designs are producible and executable given budget and schedule goals. The Navy instituted a comprehensive system engineering framework and supporting land and sea based prototyping plan, which will be completed prior to commencing production. In support of this, the Navy has developed a holistic USV work breakdown structure (WBS) framework to help coordinate developmental and systems engineering efforts applicable across the USV portfolio and efforts that are platform specific. The WBS categories are divided into broad key enablers, including HM&E (1.0), C4I (2.0), USV ICS (3.0), Common Control System (CCS) (4.0), autonomy (5.0), and prototyping efforts (6.0). The supporting land and sea based prototyping plan will use Prototype vessels and various land-based testing facilities to mature enabling technologies and qualify representative machinery. In support of the updated developmental and prototyping plan, the Navy is aligning the initial production of USVs with the risk reduction and qualification plans described in the program System Engineering Framework WBS. USVs will be capable of weeks-long deployments and trans-oceanic transits and operate aggregated with Carrier Strike Groups (CSGs), Amphibious Ready Groups (ARGs), Surface Action Groups (SAGs), and individual manned combatants. USVs will be capable of autonomous navigation, transit planning, and COLREGS-compliant maneuvering and will be designed with automated propulsion, electrical generation, and support systems. USV missions will be conducted with operators in-the-loop (with ability to provide continuous or near- continuous observation or control) or on-the-loop (autonomous operation that prompts operator action/intervention from sensory input or autonomous behaviors). USVs with integrated payload capability and prototypes employing non-organic payloads will not be capable of autonomous payload engagement or execution of a complete detect-to-engage sequence. The vessel will be incapable of payload activation, deactivation, or engagement without the deliberate action of a remote, off-hull human operator in the loop. The program will integrate current Navy combat systems programs of record that have been adapted to enable remote monitoring and operational control from an off-hull command and control point and will not be equipped with components that would enable payload engagement from onboard the vessel. USV Command and Control (C2) will be maintained via an afloat element (i.e., embarked on a United States Navy (USN) combatant), or via the ashore element (C2 station ashore). The USV program is continuing to execute a comprehensive land and sea-based prototyping strategy to develop capability increases, demonstrate key autonomy and automation enablers, and improve reliability of representative machinery. The prototype vessels support this strategy by demonstrating successful integration of government furnished Command, Control, Communications, Computers and Intelligence (C4I), combat systems, and the reliability of automated hull, mechanical, and electrical (HM&E) systems, eventually leading to a USV with the Unmanned Surface Vessel Integrated Combat System (USV ICS) and organic payloads. Early prototype vessels are enabling the Navy to accrue operational hours to gather data on autonomy, automation, and systems reliability, increase confidence in the man-machine team, and develop and refine unmanned concepts of operation (CONOPs) and tactics, techniques, and procedures (TTPs). The overarching USV development strategy views the purchase, fielding, and testing of the prototype USVs through the procurement of production USVs as a single developmental effort. The USV acquisition path will heavily leverage the results of the prototype USV developmental effort, land-based testing plan, USV industry design studies, and continued engagement with industry. The government furnished C4I suite and the USV ICS hardware and software that will be incorporated into the USV will be developed under the Unmanned Surface Vehicle Enabling Capabilities (PE 0605513N). Payloads are being developed separately under other prototyping efforts and will be further developed and/or integrated into USV under the Enabling Capabilities project. Key combat systems, payload technologies, and enablers will continue to be developed and matured. The Navy is executing a comprehensive reliability plan with the intent to discover and implement reliability enhancements into USV machinery plants as well as provide a means to qualify USV-representative machinery plants prior to award of the initial production of USVs. The effort leveraged industry engagement under the Studies Contract effort, which assisted the Navy in determining reliability enhancements, improvements, and other potential machinery plant architectures needed to achieve LUSV operational and reliability requirements. The Navy has successfully completed the testing of ancillary equipment and machinery control systems which will be qualified for use onboard USVs.

No concentration index is published for this line. This line's high-confidence links do not clear the floor for a published concentration index — at least 3 awards across 2 contractor families holding positive obligations, with positive net linked dollars. An index below that floor is a fact about the sample, not about the market. Whatever further links this line carries are medium-confidence, and what each medium evidence path does and does not establish is set out in the methodology.
