Budget figures
$143.9M discretionary + $149.4M one-time reconciliation. Discretionary change vs FY2025 enacted: +570.6%.
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 · $293.4M TOA − $143.9M J-book line = 149.4M (293.35 − 143.94 = 149.41) — $149.4M 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.
FY2026 award data is a partial year — USAspending reports awards on a rolling basis, and this corpus runs through 2026-09-04. why partial FY2026 data? →

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.

Asked vs spent: the PB2024 book requested $104.3M for FY2024; the PB2026 book reported $67.3M as actual total obligation authority — $37.0M below the request. 67.3 − 104.3 = -37.0 USD millions — the compact figures above are rounded for reading.

Description
Mission — Advanced Undersea Prototyping
The Orca Extra Large Unmanned Undersea Vehicle (XLUUV) is the Navy's initial Extra Large UUV effort that falls under the UUV Family of Systems. The Orca XLUUV effort was established to address a Joint Emergent Operational Need (JEON) and is multi-phased accelerated acquisition effort to rapidly deliver capability to the Fleet. Phase 1 was a competitively sourced design effort. Phase 2 down selected to one of the Phase 1 vendors in FY 2019 for fabrication and testing of the vehicle and support elements. Testing and delivery of the vehicles and support elements were delayed to FY23-26 due to contractor challenges and supplier issues. The Navy is working with the OEM to mitigate schedule delays by continuing to execute risk reduction testing and training through the addition of a designated test and training asset (Vehicle 0) which was delivered in FY24. The Navy is updating facilities at Naval Base Ventura County and Naval Base Kitsap to support testing, training, and workups, in coordination with large, unmanned surface vessel testing for cost efficiencies. The Navy is also updating facilities at a Forward Operating Base (FOB) to support future UUV operation in theater. Design and fabrication of a single Hunter payload will be initiated in FY26 with a planned integration to the XLUUVs at the forwarding operating base. The XLUUV has a modular payload bay, with defined interfaces, to support quick integration with future payloads/sensors. The Orca XLUUV efforts include integrating potential future payloads and capabilities which will be developed, evaluated, and preliminarily integrated leveraging the Core Technologies Program Element 0604029N. In addition, the Combat Autonomous Maritime Platform (CAMP) project will conduct competitive Extra Large Unmanned Undersea Vehicle capability demonstrations leveraging commercial sources and non-developmental prototypes in accordance with FY25 NDAA section 1032. The project will use the Defense Innovation Unit's (DIU) Commercial Solution Opening (CSO) process, prototyping, and spiral development. Systems will be assessed on vehicle range, payload capacities, and technical maturity to meet Indo-Pacific Command requirements
Mission — Adv Undersea Prototyping-Vehicles, Propulsion & Navigation
The Orca Extra Large Unmanned Undersea Vehicle (XLUUV) is the Navy's Extra Large UUV effort which is part of the UUV Family of Systems (FoS). The Orca XLUUV effort was established to address a Joint Emergent Operational Need (JEON). Orca has a modular payload bay, with defined interfaces that current and future payloads must adhere to for employment from the vehicle. The Orca XLUUV effort will integrate the currently required payload, and additional potential future payloads will be developed, evaluated, and preliminarily integrated under the Core Technologies Program Element 0604029N. Additional XLUUV technologies/capabilities risk reduction will occur in parallel, leveraging the competitive Industrial base. In addition, the Combat Autonomous Maritime Platform (CAMP) project will conduct competitive Extra Large Unmanned Undersea Vehicle capability demonstrations leveraging commercial sources and non-developmental prototypes in accordance with FY25 NDAA section 1032. The project will use the Defense Innovation Unit's (DIU) Commercial Solution Opening (CSO) process, prototyping, and spiral development. Systems will be assessed on vehicle range, payload capacities, and technical maturity to meet Indo-Pacific Command requirements.
Justification
Accomplishments & Planned Programs (1)
XLUUV Product Development
Orca XLUUV Phase 1 design was completed via a full and open competition with two industry teams. Phase 2 fabrication was down selected to one vendor for the fabrication and delivery of 5 Orca vehicles. In March 2022, the Navy added a test/training asset (XLE0) and test/fix/test level of effort (LOE) period to reduce risk of achieving performance requirements and future delivery schedule of the JEON vehicles.

Award linkage is shown for 32 of 200 profiled companies — high- and medium-confidence USAspending matches, each row labeled; medium is the weaker evidence. why partial award coverage? →

Contractor concentration
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. Both bases are in the downloadable warehouse.
Lobbying mentions
No Senate LDA lobbying filing in the tracked data mentions this program element by code or alias.
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 Advanced Undersea Prototyping. No program-specific GAO finding for this line is in the ingested data. See the DOD oversight record.
Program dossier
No research dossier for this program — dossiers cover 50 of 1,938 programs, the largest fully J-book-detailed lines by FY2026 requested dollars. why no dossier here? →
