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 · $10.9B TOA − $8.99B J-book line = 1.93B (10,920.5 − 8,994.6 = 1,925.9) — $1.93B 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 — COLUMBIA Class Submarine

MISSION: Strategic Deterrence. The COLUMBIA Class Program is an Acquisition Category (ACAT) ID Major Defense Acquisition Program (MDAP) to design, construct, and deliver a replacement for the OHIO Class Fleet Ballistic Missile Submarines (SSBNs), which begins retiring at a rate of one per year beginning in 2027. The mission of the COLUMBIA SSBN is to maintain an appropriate state of readiness to assist in deterring nuclear attack on the United States and its allies. In the event deterrence should fail, the force must be capable of launching missiles against pre-planned or adaptively planned targets. To fulfill this mission COLUMBIA SSBNs must be capable of performing extended strategic deterrent patrols without requiring assistance or replenishment. It does not have a requirement for additional capabilities or other missions unrelated to survivable strategic nuclear deterrence. Armament: Torpedo Tubes Ballistic Missile Tubes Major Electronics: Trident D5 Strategic Weapons System Command, Control, Communications and Intelligence System - Open System Architecture - Twenty-three Subsystems Note: The FY 2026 request for COLUMBIA Class Submarine includes $8,994,594 thousand of discretionary funding and $1,925,892 thousand of mandatory (reconciliation) funding for a total of $10,920,486 thousand. While the total FY 2026 discretionary funding decreased by $1,426,814 million when compared to the FY 2026 funding in the FY 2025 submission ($10,421,408 thousand), the overall funding (mandatory plus discretionary) for COLUMBIA Class Submarine increased by $499,078 thousand when compared to the FY 2026 funding in the FY 2025 submission. FY2026 is the first year of incremental full funding for the third ship, SSBN 828. Additionally, FY2026 funds the COLUMBIA Class Program to the NAVSEA 05C's 2023 cost estimate and preliminary Build II (SSBN 828-832) contract negotiations. The FY2026 budget and P5 breakout also includes Cost to Complete for Build I (SSBN 826-827), however, funding is reflected in FY2027-2030. The budget also includes continuing Integrated Enterprise Plan (IEP) funding initiatives, material procurement for future ships, and funding for the Maritime Industrial Base (MIB) (previously referred to as the Submarine Industrial Base/SIB). These MIB investments provide enterprise funding to strengthen the MIB to support a generational increase in submarine demand and includes supplier development, shipbuilder/supplier infrastructure, workforce development, technology opportunities, and strategic outsourcing. Investments are targeted to support uplift of the MIB to achieve a "1+2 " Production Cadence, strengthening the MIB and reprioritizing/growing infrastructure to support new construction goals and increased demand as well as improved maintenance and sustainment for the submarine fleet. The MIB funding profile reflects the funding provided by the Indo-Pacific Supplemental Appropriations Act, 2024 ($1,955M) to support improvements to the MIB. FY2025 Plans includes supplier development Congressional adds +$5M for explosion welding facilities and +$18.5M for tube/propulsor facilitization. In August 2020, the COLUMBIA Class program completed its Construction Authorization In Progress Review (IPR). The Milestone Decision Authority (MDA) approved the program for entry into Build I construction on 28 August 2020, pending FY2021 congressional authorization and appropriation. As a result of the IPR, the FY2022 budget submission reflected SSBN 826-837 requirements aligned to the NAVSEA 05C's 2020 cost estimate plus additional funding for SSBN 826 based on the CAPE Lead Ship Assessment (LSA) cost estimate (+$155M FY2022-FY2023). At the COLUMBIA Program Semi-Annual IPR held on August 30, 2021, the MDA directed COLUMBIA to be funded to the program baseline, including IEP funding. FY2026 reflects funding to the NAVSEA 05C's 2023 cost estimate (including impacts from inflation) as well as to the results of preliminary Build II contract negotiations for basic construction costs. The Build II preliminary negotiations accounts for anticipated cost growth based on current vendor proposals, current shipbuilder performance, and inflation. The Program is completing an updated cost estimate and CAPE Independent Cost Estimate (ICE) to support Build II contract negotiation and award. The IEP funding leverages Congressional authorities and is aligned to OSD and Navy direction to execute COLUMBIA Class schedules needed to accelerate ship delivery schedules to reduce the strategic deterrence coverage gaps during transition from OHIO SSBNs to CLB SSBNs and the transition from D5LE to D5LE2 missiles. It is crucial to maintain force structure necessary to meet USSTRATCOM requirements for Sea-Based Strategic Deterrence (SBSD). Total MIB funding of $1,352M in FY2026 is accounted for in SSBN 837 Plans Costs P-5c Cost Category to ensure it is visible and can be appropriately tracked and managed. Since the FY2025 submission, FY2026 was reduced by $50M and rephased later into the FYDP FY2021 was the year of authorization for the lead ship, DISTRICT OF COLUMBIA (SSBN 826), and was a new start program due to FY2021 being the first year of incremental full funding. FY2022 and FY2023 were the second and third year of full funding for lead ship, DISTRICT OF COLUMBIA. FY2024 was the year of authorization for the second ship, WISCONSIN (SSBN 827), and first year of incremental funding for the second ship; FY2025 is the second year of incremental funding. FY2026 will be the year of authorization and the first year of incremental funding for the third ship. The budget request supports continued detailed design and construction of CFE and GFE systems to build, test, outfit, and deliver SSBN 828 and later ships. Funding also supports Continuous Production of Missile Tubes, Advance Construction (AC), EOQ for Multi-Program Procurement, Continuous Production of Shipyard Manufactured Items, and Supplier Development to reduce COLUMBIA Class construction schedule risk executed in accordance with enhanced acquisition authorities contained within the National Sea-Based Deterrence Fund (NSBDF), 10 U.S.C. 2218a. The Navy executed a Build I contract for the first two COLUMBIA class submarines (SSBN 826 and SSBN 827), detailed below. The Navy's FY2026 budget was altered to reflect three-year incremental funding profile for all COLUMBIA (CLB) Build II Ships and continues for rest of class. This results in a reduction of $3.1B in FY2026 (shifted into follow years). This incremental full funding profile supports the phased requirements to meet the objective SSBN 828 delivery date. A Contract Modification for ongoing design/advance construction efforts was awarded on 22 June 2020, which also included the Build I Option for the First Two Ships. This was a Pre-Priced Option for the two ships, SSBN 826 and SSBN 827, and associated design/support efforts. This was a modification of the current IPPD contract (N00024-17-C-2117) and is in line with the program's approved Acquisition Strategy. The program received authorization for SSBN 826 in FY2021, funded with three years of incremental funding in FY2021-2023, and SSBN 827 was authorized in FY2024, funded with two years of incremental funding in FY2024-2025. In December 2022, program awarded an additional pre-priced contract modification of IPPD to support Build II/III Advance Procurement / Advance Construction, EOQ for Build II, and MIB efforts. CLB and VIRGINIA Class (VCS) Programs are executing an innovative contracting approach (similar to CLB Build I) which will coordinate CLB Build II with VCS new construction contracting efforts (VCS FY2024 ships and Block VI (FY2025-2029)) to maximize efficiency and stability across the industrial base. The coordination of three separate contract actions eliminates redundant effort by negotiating multiple contracts simultaneously while allowing the shipbuilders to place material orders for multiple ships in concert with VCS which improves stability for supplier base to de-risk schedules. Since the FY2025 submission, the COLUMBIA Class Program continues investment in initiatives to reduce construction schedule risk and enable cost savings (Multi-Program Material Procurement (MPMP), Continuous Production (CP) of Missile Tubes/Outfitting, Ordnance Systems and Shipyard Manufactured Components, Economic Order Quantity efforts, and Advance Construction). Increased investment in Strategic Weapons System (SWS) Shipboard Systems EOQ and Continuous Production leverages additional opportunities to mitigate obsolescence and construction schedule risks and realize additional cost savings outside of the FYDP. The Navy in FY2026 continues to fund additional IEP initiatives (EOQ/MPMP, CP, Missile Tube Outfitting, AC/AP, and Production Backup Units) which is crucial to de-risk and execute IEP Objective schedules. Total class cost savings is $2,010M. Details are contained in the P-10. The first Missile Tube Module (MTM) is funded through RDTEN Program Element 0603595N for $584M; additional $195M funds added due to MTM performance growth in the FY2026 submission.
