Budget figures
$84.3M discretionary + $100.0M one-time reconciliation. Discretionary change vs FY2025 enacted: -41.8%.
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 · $184.3M TOA − $84.3M J-book line = 100.0M (184.3 − 84.3 = 100.0) — $100.0M 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.

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 PB2021 book requested $110.3M for FY2021; the PB2023 book reported $69.4M as actual total obligation authority — $40.9M below the request. 69.4 − 110.3 = -40.9 USD millions — the compact figures above are rounded for reading.

Description
Mission — MK-48 ADCAP
The MK 48 ADCAP (Advanced Capability) Research, Development, Test and Evaluation (RDT&E) program executes incremental development of weapon performance improvements in two development product areas:(1) Advanced Processor Builds (APBs) (operational software), and (2) Torpedo Technology Insertions (TIs) (hardware). This Program Element (0205632N/0366) is tied to development programs that leverage a joint United States/Australia Armaments Cooperative Project (ACP) and develop MK 48 ADCAP technologies developed by the Office of Naval Research (ONR) and Strategic Capabilities Office (SCO). The Advanced Processor Builds (APBs) spiral engineering development process provides for continual performance improvements to the torpedo's operational software (OPSW). The Torpedo APB (TAPB) focused development testing and implementation within the APB process is being utilized to address shallow water as a critical operating area to counter near-peer adversaries and third world diesel electric submarines. In-water testing, in conjunction with laboratory simulation efforts, has shown that significant performance improvements can be made by implementing changes to weapon tactics and software algorithms. The TAPB program also leverages the Royal Australian Navy (RAN) joint torpedo program and technologies developed by ONR and SCO in the areas of torpedo broadband signal processing, tactics processing, and alertment. Torpedo Technology Insertions (TIs) will provide for significant torpedo hardware improvements and upgrades, including the transition and testing of advanced technologies from the R&D community. This approach will incorporate manufacturing development, integration and testing of transitioning technologies from ONR and SCO for ADCAP upgrades in the areas of torpedo sensors, energetics, propulsion, weapon/platform connectivity, and improved fusing. These efforts will continue torpedo development investment at a lower cost and shorter term than traditional torpedo programs. The MK 48 MOD 8 (APB 6/TI-1) Heavyweight Torpedo (HWT) program is a significant upgrade to the MK 48 MOD 7 HWT which will consist of an operational software upgrade referred to as APB 6 and a hardware upgrade referred to as TI-1. TI-1 will include a Guidance and Control (G&C) section upgrade including a new Sonar Assembly (higher density array, transmitter, receiver), and an Improved Post Launch Communications System (IPLCS). IPLCS will replace the existing copper guidance wire with fiber optics. These improvements are needed for increased performance in the presence of advanced countermeasures, shallow water, low Doppler targets, Very Shallow Water (VSW), improve fuzing, and Anti Surface Warfare (ASuW). TI-1 will also include features from three ONR Future Naval Capabilities (FNC) programs. The MK 48 MOD 9 (APB 7/TI-2) program provides extensive and important hardware and software capability improvements to the MK 48 MOD 7 and MOD 8 heavyweight torpedo (HWT). The capability improvements include a new propulsion system for increased range and advance sensing capabilities against surface and subsurface targets. The MK 48 MOD 9 (APB 7/TI-2) provides distinctly different capabilities than the MK 48 MOD 8 (APB 6/TI-1) and is intended for different operational missions. The MK 48 MOD 9 software improvements consist of the APB 7 software and algorithm upgrades for advance sensing and processing capabilities. The MK 48 MOD 9 hardware improvements consist of TI-2 hardware upgrades replacing the legacy Otto fuel engine with the Stored Chemical Energy Propulsion System (SCEPS) for increased range. The MK48 Afterbody Upgrades program leverages other existing ONR efforts outside of the APB and TI programs to identify and implement updates including sensing, afterbody performance, and increased Otto fuel range across the MK 48 ADCAP family. The Liberator provides for the development of alternative methods for launching torpedoes or similar devices.

Awards
No awards are linked to this program element at high or medium confidence — the budget→award crosswalk only asserts links it can defend, and this line has none yet.
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 MK-48 ADCAP. 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? →
