Description
Description — Strategic Missile Systems Equip
This budget supports the shipboard subsystem equipment modernization and technical refresh efforts associated with TRIDENT II D5 Life Extension (D5LE) program as well as procurement of Strategic Weapons System (SWS) equipment for deployed ballistic missile submarines (SSBNs) and shore support sites. OTHER MATERIAL SUPPORT A broad range of other material support equipment must be procured for deployed SSBNs, shore installations and contractor facilities. Included within this category are general and special purpose test equipment, launcher expendables, navigation principal items, test instrumentation in support of missile flight tests, and missile checkout equipment. This includes capital maintenance support for the Naval Industrial Reserve Ordnance Plant (NIROP) which provides for significant rehabilitation and repair work for major facility, infrastructure, and systems at the Navy owned Pittsfield, MA facilities supporting the SWS. The NIROP infrastructure and systems are housed primarily in three main buildings and include but are not limited to power, steam, and cooling systems & infrastructure, life-safety and security systems, and other critical infrastructure such as roofs, elevators, restrooms, and parking lots. Work is performed on each major system on a rolling maintenance program that is based on service life. Continued maintenance of these critical facility systems is essential for support of the on-going Fleet Ballistic Missile (FBM) programs at the Pittsfield, MA NIROP. ALTERATIONS Alterations to non-flying tactical hardware support continuing requirements for the SWS. Requirements primarily relate to shipboard investments in Commercial-off-the-Shelf/Non-Developmental Items (COTS/NDI) SWS subsystem equipment, including periodic refresh cycles, to ensure continued reliable performance of the weapon system for its extended service life to match the OHIO Class life extension. Strategic Programs Alterations (SPALTs) also entail the application of available technology to eliminate personnel safety hazards, correct design deficiencies, maintain system effectiveness by resolving equipment operability problems, achieve logistic economies, and provide for shipboard subsystem D5LE modernization efforts. Recent hardware alteration efforts include funds to (1) procure alterations to the SWS launcher and fire control subsystems; (2) procure inertial, non-inertial, and Electrostatic Gyro Navigator (ESGN) navigation subsystem equipment on deployed SSBNs and installed at supporting shore facilities; (3) test instrumentation used on SSBNs, support ships, and at the Eastern Test Range, the TRIDENT Refit Facility (TRF) - Bangor, and TRF - Kings Bay; and (4)procure missile handling equipment, missile test and readiness equipment, and surface support equipment. Installation of approved SPALTs are performed on a turnkey basis in conjunction with the procurement of equipment. Alterations funding supports the Shipboard System Integration (SSI) program and is utilizing a COTS based strategy that integrates common electronics from Fire Control (FC), Launcher, and Navigation (NAV) into the fire control sub-system. This includes refreshing inertial systems to ensure the TRIDENT II (D5LE) weapon system can be sustained through the life of the OHIO Class SSBNs and serve as the baseline for the COLUMBIA Class SSBNs. Below is a description of each current SSI Increment (Inc): SSI Inc 8: This ongoing effort provides replacement of the 30 year old ESGN which needs a refresh of inertial technology components, provides replacement of the Electronic Equipment Consoles (EEC), and updates Navigation Subsystem software to accommodate ESGN replacement navigator. Also, provides SWS subsystem SPALTs for FC and Trident Training Facility (TTF) NAV Lab trainers, and Shipboard Data System (SDS)/Data Recording System (DRS) SPALT changes which are driven by data requirement changes. The ship alterations (SHIPALTs) retain NAV Center bedplate, cabling, chilled water/ventilation, and electrical power. SSI Inc 11: Completed in FY 2025, Inc 11 developed the Launcher Initiation System (LIS) for backfit onto OHIO Class D5LE. This provides a technical refresh of 30+ year old technology to ensure long term system reliability. Ship/Strategic Weapon Support Systems (SWSS) SHIPALT also replaces electrical cable with hybrid fiber-optic/electrical cable. SSI Inc 13: Completed in FY 2025, Inc 13 provided Shipboard Systems Refresh for Fire Control System (FCS), Navigation (NAV), and Missile Test and Readiness Equipment (MTRE) to integrate with the subsystems. SSI Inc 15: As the prerequisite is SSI Inc 13, Inc 15 provides pre-configuration and post-configuration support of Inc 8 and Inc 11. Inc 15 provides refresh alterations for the fire control subsystem. SHIPBOARD SYSTEMS MODERNIZATION PORTFOLIO (SSMP) Program SSP is undertaking a strategic modernization of the shipboard systems architecture to harness new technologies and leverage modern engineering methodologies. This will ensure credible, reliable and adaptable capabilities are provided to the warfighter and nation at the speed of relevance. SSMP is the overarching program management framework for the integration of all current and future acquisition activity related to SWS shipboard systems. It includes design work to achieve an optimized shipboard architecture across SWS subsystems as well as the integration of all other shipboard systems development and sustainment activities. SSMP has been defined in four major programmatic elements: A. Advance Development and Tech. Maturation B. Shipboard Re-Architecture Design C. Obsolescence Management D. Continuous Capability Insertion (C2IS) A. Advance Development and Tech. Maturation consists of multiple incremental alterations to the shipboard systems of the SWS that primarily addresses obsolescence and sustainment. The SSI Increments program employed a strategy of targeted technology refreshes and functional consolidations in conjunction with life of type buys to manage obsolescence within the shipboard systems. While the increments were successful in achieving limited modernization of portions of the system design they did not principally address a holistic modernization of the underlying architecture of the collection of shipboard systems (Fire Control, Navigation, Shipboard Data System, and Launcher) that was established with TRIDENT II D5 in the 1980s. The SSI Increments program began with SSI Increment 1 which started in the early 2000s and will conclude with the deployment of Increment 15 in the late 2020s. B. Shipboard Re-Architecture builds on the Increment 15 system baseline and is designed to achieve an architectural re-design of the shipboard systems. Leveraging modern technologies and approaches, this effort will eliminate the architectural constraints that hinder adaptability in the current SWS. Whereas the SSI Increment program focused on minimizing lifecycle costs around a stable system capability and performance baseline, Shipboard Re-Architecture focuses on maximizing scalability and adaptability in the architecture to enable rapid response to a dynamically changing threat environment while minimizing lifecycle costs. This shift in approach is needed to counter the rapidly changing threat environment that results from two near-peer nuclear adversaries and resultant dynamic needs for SLBM capability. Shipboard Re-Architecture is structured around three lines of modernization which will establish a shipboard common infrastructure. Once the shipboard common infrastructure is in place, legacy software can be refactored to make use of standard functions and features and new capabilities can be more easily and rapidly introduced. The three lines of modernization are: 1. Implementation of a modern General Purpose Computing (GPC) infrastructure. This is critical to provide a scalable computational element that leverages modern technologies to achieve critical improvements in computational capability and cyber resiliency. 2. Implementation of a modern Deterministic Computing Element (DCE) infrastructure. This is critical to provide a modernized real-time embedded computing infrastructure based on the latest technologies and industry standards for high availability, high criticality systems. 3. Implementation of a modern data architecture and shipboard-flight interface infrastructure. This is critical to modernize communication protocols, software design, data structures, and interfaces to improve cyber security, supportability, and maintainability of the system. It is also an essential enabler to support emerging technologies under development for the flight and re-entry systems (e.g. TRIDENT II D5 Life Extension 2 (D5LE2) and Mk7/W93). Shipboard Re-Architecture will be executed using an agile methodology and digital engineering methods. Smaller alterations to the existing shipboard systems will be executed over time rather than establishing several large incremental procurements. This approach is important for two reasons. First it will allow SSP to respond rapidly to changing National priorities while still making strategic investments in the re-architecture. Second, by overlapping and sequencing the roll off from SSI Increments 8 and 15 with the ramp up of Shipboard Re-Architecture effort, SSP is able to leverage the established industrial base which is a significant factor in managing risk, ensuring expertise and unique knowledge pertaining to the SWS design is retained and applied to the re-architecture efforts. Shipboard Re-Architecture is strategically phased to also support the critical D5LE2 experimental test flight program in the early 2030s and planned COLUMBIA class refreshes. FY 2026 is the first deployment of the Shipboard Re-Architecture development. C. Obsolescence Management: This aspect addresses the need to continuously sustain the shipboard systems. This includes planning for technology refreshes and obsolescence management during all phases of SSMP, leveraging the modernized architecture established by the Shipboard Re-Architecture efforts. Specifically, the decoupling of hardware and software and introduction of virtualization technologies in the re-architecture will serve to enable rapid insertion of technology refreshes and simplify obsolescence management of the shipboard systems. The objective is for the program to be capable of hardware insertion every two years and annualized software releases. D. The C2IS element of the SSMP defines the approach to both sustaining the shipboard elements of the SWS and ensuring adaptability and timely insertion of capabilities to meet the dynamic threat environment and needs of the Nation. C2IS is fully integrated with re-architecture efforts to enable an appropriate balance of acquisition decisions between re-architecture, obsolescence management, and capability insertions. As the Shipboard Re-Architecture initiative is incrementally realized, the new architecture will enable a faster cadence that is more adaptable and affordable to changes. This will allow SSP to rapidly address both obsolescence and capability insertion, including improvements in SWS performance and the integration of support for advanced missile/re-entry technologies. The overall SSMP program addresses the need to provide capability to the Warfighter. Before, during, and after the re-architecture efforts are complete Shipboard Subsystems must be able to adapt and introduce capability to keep pace with the changing threat environments. SSMP will focus on refreshing the shipboard architecture, which will allow adaptability for the quick and effective deployment of affordable solution along with the incremental deployment of capabilities required to sustain SWS effectiveness in a changing threat environment. This will maximize the ability of the SWS to adapt to changing threats. This involves enhancing the product and optimizing the SWS to satisfy STARTCOM specifications. This entails updating outdated shipboard systems components with new technology to guarantee the deployed SWS's availability and dependability while preserving compatibility with the pull-through components that are a requirement of the COLUMBIA design. To achieve this goal, a balance will need to be maintained between shipboard architectural changes and capability insertion. Once the Shipboard Common Infrastructure is in place the ability to rapidly insert capability will be improved and is essential for the SWS to adapt and respond to the ever-changing threats of the future. TRAINING This category provides for procurement of, and alterations to, both tactical and non-tactical equipment required at submarine training facilities to train personnel in the operation and maintenance of launcher and handling, fire control, navigation, missile checkout, and test instrumentation subsystems. Each training facility consists of an integrated family of system and unit laboratories that interface with a training simulation system to provide complete and realistic training for replacement and off-crew personnel, both officer and enlisted, as required for manning of SSBNs and shore facilities. Funding is budgeted to procure training-unique equipment required as the result of alterations to SWS tactical equipment, including those associated with D5LE. COLUMBIA CLASS Funding in this category is in support of the COLUMBIA Class SSBN for the procurement of trainer equipment and execution of Trident Planned Equipment Replacement Program (TRIPER) efforts. Funding is required to develop, procure, install and test the SWSS trainer equipment suite within the COLUMBIA Class Kings Bay (KB) TTF 2-tube configuration. The SWSS trainer equipment suite simulates the tactical configuration required to conduct COLUMBIA crew training and certification beginning in January 2026. Procurement of select SWSS components, such as training missile tubes and associated on and off-tube components, as well as engineering labor required to integrate the COLUMBIA design into the trainer configuration, commenced in FY 2022 to ensure initial equipment is installed before exterior building construction is complete (FY 2024) and all remaining hardware will be delivered in FY 2024 and the first half of FY 2025 for installation, checkout and testing. Similar procurements for the COLUMBIA Class Bangor TTF commence in FY 2028. Per OSD(A&S) and SECNAV direction, COLUMBIA Program costs reflect requirements per NAVSEA 05C's 2023 program cost estimate. In support of the August 2020 Lead Ship Authorization In-Process Review, funding was increased primarily driven by properly priced TRIPER spares and corrected re-phasing of training requirements added to the program. The 2023 program cost estimate reflects updates based on awarded U.S. contracted values, updated labor rates, and increased material costs driven by inflation.
Justification
Justification — Strategic Missile Systems Equip
The FY 2026 request was reduced by $2.980 million for civilian personnel to optimize the workforce in compliance with Executive Order 14210, "Implementing the President's Department of Government Efficiency Workforce Optimization Initiative." The FY 2026 request for Strategic Missile Systems Equip includes $491,179 thousand of discretionary and $1,820 thousand of mandatory funding (reconciliation) for a total of $492,999 thousand. The mandatory funds include procurement of both hardware and related software of non-tactical IT equipment and supports the acceleration of the development, procurement, and integration of the Nuclear-Armed Sea-Launched Cruise Missile program (SLCM-N). Further information for this reconciliation request is provided in Section 20008 (Nuclear) of the Reconciliation Exhibit. OTHER MATERIAL SUPPORT A broad range of other material support equipment must be procured for deployed SSBNs, shore installations and contractor facilities. Included within this category are general and special purpose test equipment, launcher expendables, navigation principal items, test instrumentation in support of missile flight tests, and missile checkout equipment. Amounts included within this category are subdivided as follows: Launcher and Handling Equipment: Cost Codes 1.2 and 1.3 provide for Gas Generator (GG) Production and GG Case Hardware. GGs are utilized to eject Trident II (D5) missiles from the missile tubes during a launch. GG and GG case hardware are continuing to be procured under the revised acquisition strategy where 20 gas generators are procured every other year (vice 10 per year) which reduces lot testing costs associated with GGs while still allowing for continuous production due to the lead time of production. In the alternating years, gas generator case hardware is procured, in the quantity necessary to support the replacement of cases for expended/fired GGs. These quantities vary based on testing events. Cost Code 1.2 - GG Production funding in FY 2026 decreases as no GG will be procured. This is a decrease from 20 in FY 2025 in accordance with the revised acquisition strategy of alternate year procurements. Cost Code 1.3 funding provides the procurement and qualification of GG Case Hardware required to replace cases for expended/fired GGs. Funding in this category fluctuates year to year due to flight schedules. Funding increases from FY 2025 to FY 2026 since there are surface launch test facility events necessitating replacement of case hardware. Cost Code 1.7 FY 2026 begins the procurement of 6 Ballast Transport Fixtures (BTFs). BTFs are a crucial component in the logistics process. They facilitate easy transportation of D5 ballast assemblies and, importantly, provide a pivot base. This pivoting capability streamlines the loading and unloading process, making it significantly more efficient. This procurement of additional support equipment is driven by the life extension of SSBNs beyond anticipated service life. Fire Control Equipment: Cost Code 2.1 funding provides for procurement of continued capital maintenance projects at the Naval Industrial Reserve Ordnance Plant (NIROP) in Pittsfield, MA. The Navy NIROP facility in Massachusetts is a large multi dwelling facility, encompassing almost 900,000 sq. ft. There are three main ordnance plant (OP) buildings on the NIROP facility, OPs 1, 2, and 3. The OPs were built in the 1940s and 1950s, and the last major renovations were in the 1970s. Funding fluctuates annually based on specific maintenance projects necessary to correct environmental, safety, and energy conservation deficiencies. FY 2026 scope includes OP1 load center replacement, OP3 Boiler replacement and OP2 air handler replacement. Cost Code 2.2 provides for Auxiliary Systems Equipment Refresh. The Auxiliary Systems Refresh is required to keep shipboard auxiliary systems operational and able to support the tactical development and training mission. Decrease in FY 2026 is due to completion of Auxiliary Systems Tech. Refresh (ASTR) #3, which is final production, and installation of Weapon System Simulator (WSS) and Training Stimulation System (TSS) kits and initial production of MICT kits. Funding in FY 2026 begins year one of a two-year agile development for ASTR #4. ASTR #4 is an operating software only refresh to maintain cybersecurity. Cost Code 2.4 FY 2026 increase initiates a refresh of the existing SSP Advanced Inventory and Logistics (SAIL) system to include software and hardware procurements necessary for the system to meet Information Assurance (IA) compliance requirements. Refresh required to address heightened cyber security risks. Cost Code 2.5 provides refresh of Targeting Software which supports all SLBM Targeting and USSTRATCOM support functions. These functions involve development and testing of mission planning software for integration into strategic planning software at USSTRATCOM, training and analysis software used at SSBN Task Forces 134/144, targeting software used in shipboard fire control software. This targeting software is used onboard a SSBN and sent to USSTRATCOM mission planning which develops Strategic war plan. Minor fluctuations occur year to year as required updates change based upon mission needs. FY 2026 increases due to required refreshes to meet strategic requirements. Instrumentation/Missile Test Equipment: Funding in all years provides for shore based and shipboard test instrumentation equipment in support of missile flight tests. Cost Code 4.5 funds Flight Test Instrumentation (FTI) equipment. Scope varies annually based on specific FTI systems being refreshed. The FY 2026 costs decrease is due to the refresh of Midcourse Radar (MCR) being completed in FY 2025. FY 2026 will support the replacement of the Portable Antenna Telemetry System (PATS). The PATS helps collect telemetry data during the midcourse of SSPs flights which is necessary to receive and record critical missile and reentry telemetry data in support of weapon system performance evaluations of Trident II D5LE flight tests off the Eastern Range as required by USSTRATCOM. This includes both Demonstration and Shakedown Operations (DASOs) and (Follow-On) Commander Evaluation Tests (F/CETs). The telemetry data collected by PATS is required to assess accuracy and reliability of the Trident II D5LE strategic weapon system. Information Technology (IT): Cost Code 5.1 funding in all years provides for non-tactical IT equipment acquisitions (hardware and related software) in support of the SSP enterprise. This includes the IT hardware and software components connected to the Strategic Weapons System Network (SWSNET). In FY 2026, hardware procurement costs increase due to increased needs for new nuclear modernization development programs (including D5LE2, W93/Mk7, SLCM-N) and the establishment of new Program Management Office locations across the United States. ALTERATIONS Alterations to non-flying tactical hardware are continuing requirements for the SWS. Requirements relate primarily to shipboard investments in (COTS/NDI) SWS subsystem equipment, including periodic refresh cycles, to ensure continued reliable performance of the weapon system for its extended service life to match the OHIO Class life extension. SPALTs also entail the application of available technology to eliminate personnel safety hazards, correct design deficiencies, maintain system effectiveness by resolving equipment operability problems, achieve logistic economies, and provide for shipboard subsystem D5 life extension modernization efforts. Funds are required to procure alterations to the SWS launcher and fire control subsystems; to inertial, non-inertial, and ESGN navigation subsystem equipment on deployed SSBNs and installed at supporting shore facilities, and to missile handling equipment, missile test and readiness equipment, and surface support equipment. Installation of approved SPALTs is performed on a turnkey basis in conjunction with the procurement of equipment. Use of COTS/NDI has been initiated and is being implemented in all subsystems, wherever possible. Launcher and Handling Equipment: Cost Code 6.3 Efforts in FY 2026 continues redesign of D5LE Missile Hoist. FY 2026 efforts increase with Hoist Controller Proofing and initiation of Hoist Overhaul 2.0 Non Destructive Testing as part of the electrical/mechanical mid-life overhaul to ensure availability through 2050. Efforts will incorporate modularity and COTS components while addressing existing safety/electrical code concerns. Cost Code 6.4 continues the Ejector group handling equipment life cycle refresh SPALT and procures one Development/Evaluation Kit. Additional FY 2026 efforts are decreasing from FY 2025 include procurement of a Laser Safing Unit Test Fixture, 23 Force and Deflection Kits, and initiating Inert O/I Gas Generator Development, and the SWFLANT Mobile Test Bed Refreshment. These SPALTS are necessary to address aging and obsolescence issues. Fire Control Equipment: Cost Code 7.1 Portable Computing Devices (PCD) Refresh SPALT FY 2026 increase due to PCD Development, Qualification tasks, and Acceptance Testing initiation in preparation for full PCD refresh cycle in 2027. Cost Code 7.2 Minor SPALTs funds non-SSI related FC development efforts; capability insertions; and sustainment. These efforts include FC enhancements and corrections for auxiliary systems, training systems changes, System Engineering Integration Team (SEIT) efforts, and software development. FY 2026 increase is due to FC software revision x62 which contains required software and targeting compatibility updates required to support our ability to operationally deploy on both COLUMBIA and OHIO platforms. Navigation Equipment: Cost Code 8.2 provides for Legacy ESGN SPALTs. Effort continues in FY 2026 to fund hardware retrofits necessary during initial deployment of Increment 8. This funding is necessary to allow for the implementation and procurement of these changes to ensure the maintainability improvements are integrated, and that the newly deployed navigation systems remain able to meet weapon system accuracy and availability. Cost Code 8.3 FY 2025 ends efforts on the refreshing of the Trident Data Delivery System (TDDS). FY 2026 includes the ramp up of production and support of the TR-143A transducers for the hydrophone with the procurement of 7 kits to replenish stock for OHIO SSBNs. Cost Code 8.6 Provides for development of the Broadband Navigation SONAR Navigation Sonar System (BBNS), which transitioned from a Small Business Innovation Research (SBIR) project to a production effort. This initiative focuses on the modernization and extension of the existing navigation sonar technology developed in the 1970s and removes operational constraints within the current system and reduce sensitivity to operational environments. The decrease in funding from FY2025 to FY2026 is primarily driven by the completion of the Broadband Navigation Sonar (BBNS) testing and validation for the tactical navigational aids (NAVAIDS) system. Additionally, the NSS Operational Navigation Program (NON) is transitioning from engineering code to tactical code in preparation for the TR-F1 software release. ALTERATIONS (SSI and SSMP) The majority of the Alterations funding supports the Shipboard System Integration (SSI) program which utilizes a COTS based strategy that integrates common electronics (from Fire Control, Launcher, Navigation and Shipboard Data Recording Systems) into the fire control sub-system as well as refreshing inertial systems in order to ensure the TRIDENT II (D5) weapon system can be sustained to support both the OHIO class submarines through their end of life as well as support the COLUMBIA class submarines currently in production. Below is a description of each current SSI Increment (Inc): SSI Inc 8: Inc 8 provides replacement of the 30-year-old Electrostatic Gyro Navigator (ESGN) which needs a refresh of inertial technology components, replacement of the Electronic Equipment Consoles (EEC), and updates to Navigation Subsystem software to accommodate the ESGN replacement navigator. Also, provides SWS subsystem SPALTs for FCS and TTF NAV Lab trainers, and SDS/DRS Software SPALT changes which are driven by data requirement changes. The SHIPALTs retain NAV Center bedplate, cabling, chilled water/ventilation, and retain electrical power. The current ESGN was designed and deployed in the early 1980s with a 20-year designed service live. This refresh is critical to ensure the program continues to meet USSTRATCOM requirements, and to ensure the operational availability of the OHIO, VANGUARD, COLUMBIA and Dreadnought SSBNs. Inc 8 efforts in FY 2026 include: Cost Code 10.8 Funding decreases from FY 2025 to FY 2026 as SHIPALT installation completes on the final 2 boats, a decrease of 1 boat from FY 2025. Cost Code 10.9 funding decreases in FY 2026 following final installation of Inc 8 enabling SPALT. Cost Code 10.10 funded a fault isolation capability for Gyroscopes. Currently, for a gyro failure, CONOPs requires removing and replacing all three gyroscopes onboard the SSBN. Once established, the capability to diagnose which gyroscope is faulty allows for the non-faulty gyroscopes to be placed back into stock. This increased availability allows for a decrease in new gyroscope procurement. The total gyroscope quantity produced for Increment 8 has been decreased, with the elimination of planned procurements as a result of the decision to pursue this fault isolation capability. SSI Inc 11: Launcher Initiation System (LIS) was developed to backfit onto OHIO Class D5LE. This provided a technical refresh of 30+ year old technology to ensure long term system reliability. This SHIPALT replaced electrical cable with hybrid fiber-optic/electrical cable. Inc 11 efforts completed in FY 2025: Cost Code 11.6 decreases in FY 2026 due to final installation of Launcher system Increment 11 LIS Fiberoptic cables in FY 2025. Cost Code 11.7 budget decreases from FY 2025 to FY 2026 due to the completion of LIS Fire Control SPALT kit installation efforts. SSI Inc 13: Inc 13 provided Shipboard Systems Refresh for FCS, NAV, and Missile Test and Readiness Equipment (MTRE) for integration with the subsystems. Cost Code 12.1 provided MTRE refresh to integrate with Fire Control software changes for SSI Inc 13. FY 2026 funds decreases from FY 2025 due to completion of SPALT accomplishment. SSI Inc 15: Inc 15 provides pre-configuration and post-configuration support of Inc 8 and Inc 11. Inc 15 is a critical path and the baseline for the deployment of the COLUMBIA Class SSBN. Inc 15 involves refreshes to several subsystems such as alterations for fire control equipment, navigation, launcher, and trainer subsystems. SSP reduced the efforts of SSI Inc 15 to the minimally required effort to address obsolescence issues which are required for the SWS to be the initial baseline for the COLUMBIA class SSBN. Inc 15 efforts in FY 2026 include: Cost Code 13.3 provides funding for hardware required for Inc 15 updates to the Fire Control system. FY26 begins to cover the five-year service life extension of five OHIO-class submarine hulls, ensuring continued support until 2043. This includes producing 5 additional SPALT Kits for OHIO Refresh 2 and 3, along with the necessary planning, equipment, and installation labor to maintain consistency with the rest of the OHIO-class fleet. Cost Code 13.5 funds installation of Increment 15 Fire Control kits. FY 2026 decrease as FY2026 is the final year of installation of Increment 15 initial installation proofing efforts. Installed equipment includes MIN Network Switch, Server, Portable Network Device and Portable Computing Devices, along with the mechanical mounting components and cabling and associated software. SHIPBOARD SYSTEMS MODERNIZATION PORTFOLIO (SSMP) Program SSMP is an integrated modernization program structured and phased with SSI to leverage the established industrial base supporting all aspects of the Shipboard sub-systems. This will enable the SWS to be more agile and adaptable to the evolving threats and warfighter needs. Cost Code 14.1: Advanced Development and Technology Maturation FY 2026 efforts include refining the shipboard architectural descriptive model, performing technology trades to support common infrastructure development, evaluation of next-generation COTS technologies to replace those currently used in the SWS, and the development of core common infrastructure capabilities including General Purpose Computing, Virtualization, Secure Communications, System Timing, and Embedded Processing. Cost Code 14.2: Shipboard Re-Architecture Development FY 2026 increase is due to deployment of common servers that implement the initial infrastructure for a General Purpose Computing (GPC) element. The GPC is the necessary system that is designed to handle a wide variety of shipboard refreshes that will help create an environment for agile development. Efforts shift from development which was completed in FY 2025 for virtualization infrastructure, integration of cyber-security features, porting select SWS software to Linux-based virtual machines, the establishment of related software infrastructure, and design of the next generation workstation. Cost Code 14.5: SSMP Production Hardware Cost Code 14.5 consists of the production of the SSMP hardware. FY 2026 finalizes Transition to Production and procures the first increment of On-board Repair Parts (OBRPs), Ready Spares, and Supply System Spares, along with the first four Tactical SPALT Kits and two shore site Upgrade Kits. It is also the start of procurement of hardware components such as servers, power inverters, network switches, encryptors, and other equipment that enable a gradual transition away from obsolete central processing units. This refresh effort will also enable the program to fulfill modernized computing requirements for fire control software. A transition to off-the-shelf software (COTS; MOTS; GOTS) away from bespoke technology enables the program to adhere to industry best practices. The implementation of this new strategy will enable improved commonality between Fire Control and Navigation shipboard subsystems; creating a more streamlined, efficient, and effective approach for future refreshes. TRAINING SUPPORT EQUIPMENT: Cost Code 15.1 This category provides for procurement of, and alterations to, both tactical and non-tactical equipment required at submarine training facilities to train personnel in the operation and maintenance of launcher and handling, fire control, navigation, missile checkout, and test instrumentation subsystems. Each training facility consists of an integrated family of system and unit laboratories that interface with a training simulation system to provide complete and realistic training for replacement and off-crew personnel, both officer and enlisted, as required for manning of SSBNs and shore facilities. Funding is budgeted to procure training-unique equipment required as the result of alterations to SWS tactical equipment, including those associated with D5 life extension. In FY 2026, the Shipboard Modernization (SWS Alignment) program increases due to the initiation of its documentation delivery phase, which focuses on creating documentation and establishing maintenance capabilities. COLUMBIA CLASS: Cost code 16.1 funding for COLUMBIA Class TRIPER spares was initiated in FY 2022. FY 2026 funds continue Kings Bay and Bangor Team Trainer procurements and TRIPER spares procurements. FY 2026 also includes Industrial Plant Equipment procurement, which will continue through 2030.
