Budget figures
$203.4M discretionary + $34.3M one-time reconciliation. Discretionary change vs FY2025 enacted: +8.1%.
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 · $237.7M TOA − $203.4M J-book line = 34.3M (237.7 − 203.4 = 34.3) — $34.3M 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.

Description
Description — LCS In-Service Modernization
Modernization/maintenance efforts support Littoral Combat Ship (LCS) requirements to remain operational and meet mission needs. This line provides funding for ship changes and improvements related to mandatory safety, cyber security remediation, habitability, obsolescence, reliability, command and control, and communication modifications to maintain LCS operational availability and achieve ships' expected service life. Funding covers planned CNO availabilities and two years of planning costs and long lead time materials (LLTM) in advance of CNO availabilities. This line provides funds for the procurement, planning, installation design, and installation for Lethality and Survivability (L&S) modifications for both LCS variants (Independence and Freedom). L&S modifications seek to leverage existing Navy Program of Record systems allowing for more rapid implementation of holistic combat system enhancements. These modifications will improve displays, infrastructure, radar, tactical data link, cybersecurity, and navigation capabilities. L&S introduces commonality between LCS variants and other surface combatants leveraging common source libraries, Total Ship Computing Environment (TSCE), MK-20 Electro-Optical Surveillance System, Surface Electronic Warfare Improvement Program, Nulka, MK-160 Gun Computer System, Data Links (IND only), Mode 5 IFF (IND only) and Navigation systems. The use of Navy Standard systems improves capability, simplifies training, and decreases life cycle costs. MT002 - LCS Class Design Improvements This budget line covers the procurement and installation of a Combat Systems and C4I Condition Based Maintenance (CBM) System, designed to monitor and collect maintenance data then periodically transfer the data ashore via a Virtualized Data Transport System (VDTS) for analysis. The CBM equipment currently monitors performance of SPS-75 and SPS-77 Radars, MK-49 RAM, and MK-110 Gun, but the Program Office is researching the potential for other systems to be monitored. MT003 - LCS Maintenance Modernization This budget line funds back-fit, upgrade, and fact of life obsolescence changes on both Freedom and Independence Variant Littoral Combat Ships. The Modernization construct is split out into 7 categories: Safety; Targeted Performance Enhancement; Obsolescence; Advanced Engineering Control System (AECS); Communication; Hull, Mechanical and Electrical (HM&E); and Navigation. These categories enable improved planning and tracking of ship changes as technology and mission evolve. The scope/requirements for maintenance modernization is dependent on hull availability, applicability, procurement timeline, and ship alteration maturity. MT004 LCS Lethality and Survivability Lethality and Survivability (L&S) funding provides for hardware procurement and installation of a common Combat Management System (CMS) comprised of Government Furnished Equipment (GFE), associated technical support data to upgrade existing contractor furnished equipment, and associated cybersecurity modifications that are back-fit onboard in-service LCS platforms. Funding also provides the non-recurring engineering development technical data packages and hardware and software packages necessary to integrate and test the common software baseline for LCS Class variants. Production and planning support services for these upgrades are phased over a three (3) year span starting two (2) years prior to installation on a per hull basis, with installation accomplished during planned CNO Availabilities. L&S plan upgrades the following systems to GFE resulting one combat system baseline with a common Combat Management System: TSCE, MK-20 Electro-Optical Surveillance System, Surface Electronic Warfare Improvement Program, Nulka, MK-160 Gun Computer System, Data Links (IND only), Mode 5 IFF (IND only) and Navigation systems. MT005 LCS Combat System Modernization Modernization of LCS Combat System hardware and software occurs through development and procurement of Engineering Change Proposals (ECPs) and associated Ship Change Documents (SCDs) not addressed by Lethality and Survivability (L&S) upgrades. CS Modernization covers obsolescence/diminishing manufacturing shortages, improved system performance, safety, cyber security, and the procurement of specialized test equipment. Procures initial outfitting spares for critical systems and subsystems unique to LCS class ships. Increases material availability, decreases maintenance turn-around times, and increases Operational Availability (Ao) at lower replacement costs. The official schedule for CNO Availabilities is maintained in the NDE and updated by Commander Naval Surface Force Atlantic and Pacific schedulers. The CNO approved schedule for LCS Availabilities included in the requirements is as follows (as of 03 December 2024): CNO avails awards: FY25: LCS 10, 12, 14, 28 FY26: LCS 13, 15, 16, 20, 22, 30, 32, 34 FY27: LCS 6*, 17, 18, 19, 21, 23, 25, 27 FY28: LCS 8*, 14, 24, 29, 31, 36 FY29: LCS 12, 13, 15, 16, 26, 38 FY30: LCS 10, 17, 18, 19, 21, 23, 25, 28, 30, 32 * - Pending CNO Availabilities Each ship requires different alteration packages that vary in scope and cost based on individual ship configurations. Therefore, funding requested for availabilities does not reflect a standard cost per availability, but funds required work for each specific hull. Note: Due to contract award dates, funds for install are awarded approximately 120 days prior to the start of the availability, meaning availabilities that start within the first quarter of a FY are awarded in the prior FY. [P3A / LCS Maintenance Modernization]: PBIS Issue 54824, Retains LCS 6 and LCS 8 and decommissions outside the FYDP. Increases players in the field for Independence Class ships. The current VMS system is OBE come March 1st, 2026 and the HW portion for this fix has a LLTM of 6 months. LCS 6 and 8 CNO availabilities are planned to begin in FY28 with LCS 6 having an FY27 award. There are milestones and procurements that will be strained if we do not plan to FY28 availabilities such as LLTM, ship checks, SIDs (Ship Installation Drawings), and TDP revisions (Technical Data Packages). Installs for TSCE and AECS will have better support from installation teams if these are FY28 CNO availabilities.
Justification
Justification — LCS In-Service Modernization
The FY 2026 request was reduced by $.322 million for Advisory and Assistance Services to promote efficiencies and advance the policies of the Administration in alignment with Executive Order 14222, "Implementing the President's Department of Government Efficiency Cost Efficiency Initiative."
