Mission — Ship Prel Design & Feasibility Studies source

0409 - This project provides Test and Evaluation (T&E) requirements for DDG-51 Flight III ships and efforts for the Navigation, Aviation and Hull, Mechanical & Electrical (HM&E) Cyber Enclaves Design for implementation on future new construction ships. T&E will concentrate on verifying integration and interoperability of employed technologies and systems in the DDG-51 FLT III design to achieve the mission capabilities and performance requirements as defined in the DDG-51 Flight III Capability Development Document (CDD) to reach Initial Operational Capability (IOC). T&E functions will include the evaluation of Critical Technical Parameters (CTP), Measures of Effectiveness (MOE), Measures of Suitability (MOS), and Key Performance Parameters (KPP). Funding is also planned for the execution of Developmental Testing (DT), Operational Testing (OT), Live Fire Test and Evaluation (LFT&E), and Full Ship Shock Trials (FSST). The Navigation, Aviation and Hull, Mechanical & Electrical (HM&E) Cyber Enclaves Design effort will provide a new design to physically separate Hull, Mechanical, and Electrical (HM&E) communications from Navigation communications to meet multiple DoD Directives/Instructions on Cybersecurity and Navy Joint-SYSCOM Cybersecurity Standards on Enclave management. This design will be utilized to support implementation on future new construction DDG 51 class ships. 0411 - The Navy's DDG(X) program is the Navy's Future Guided Missile Destroyer ship acquisition program to follow the DDG 51 class that is essential to field capabilities required for the future fight as validated by the Future Surface Combatant Force (FSCF) ICD, FSCF AoA, and Future Naval Force Study (FNFS). DDG(X) will integrate non-developmental systems into a new hull design that incorporates platform flexibility and the space, weight, power and cooling (SWAP-C) to meet future combatant force capability/system requirements that are not achievable without the new hull design. The DDG(X) platform will have the flexibility to rapidly and affordably upgrade to future warfighting systems when they become available as well as have improved range and fuel efficiency for increased operational flexibility and decreased demand on the logistics force. DDG(X) will provide an Integrated Power System (IPS) with flexibility to enable fielding of high demand electronic weapons, sensor systems and computing resources. To decouple ship development risk from technology risk, accommodation of additional future capabilities will be pre-planned; these future capabilities may include missile launchers capable of larger weapons to exceed adversary capabilities, high power lasers, or other systems that can be efficiently incorporated when developed and demonstrated. 3262 - T-AGS(X), Oceanographic Survey Ship, is the planned recapitalization of the Pathfinder Class (T-AGS 60) six vessels which are approaching the end of their life starting in 2024. The T-AGS ship is a multi-mission, world-wide deployable oceanographic survey ship providing oceanographic capabilities in coastal and deep ocean areas. Data collected from charting the world's coastlines is vital in support of undersea warfare, enemy ship detection, and humanitarian assistance and disaster relief efforts. The recapitalization ensures the CNO requirement for eight T-AGS survey ships. 3389 - Naval Operational Logistics (OPLOG) Integration IPT Development - Develops enabling technologies for future and in-service afloat operational logistics and integrated supply force and combatant logistics requirements; and conducts cooperative initiatives with acquisition programs, program sponsors, engineering managers, the Navy science and technology community and Fleet customers. OPLOG develops integrated, cross-platform (i.e. applicable to more than one ship class/type) operational logistics and energy conservation technologies and capabilities as well as draft acquisition and operations policy ensuring future Naval systems leverage emerging logistic capabilities and technologies to provide operationally effective and energy efficient logistics delivery. 4044 - Medium Landing Ship (LSM) is a medium-sized landing ship that enables distributed maneuver and logistics such as Distributed Maritime Operations (DMO), Littoral Operations in a Contested Environment (LOCE), and Expeditionary Advanced Base Operations (EABO), in support of the Marine Littoral Regiment (MLR). It is designed to fill the gap in capability between the Navy's large, multipurpose amphibious warfare class ships and smaller landing vessels. This ship will deploy tailored logistics, select power projection and support strike capabilities via the embarked MLR. With the authorities granted in Section 128 of the FY 2025 National Defense Authorization Act, the LSM program will procure an existing design to construct Non-Developmental Vessels (NDV). This procurement is known as LSM Block 1.

Mission — DDG(X) Concept Development source

To compete and win in an era of great power competition, the United States needs a balanced Naval force, capable of striking targets from all domains. The force design must emphasize distributed awareness, lethality and survivability in high-intensity conflict. The force must be adaptable, demonstrate presence, and be capable of projecting power by delivering precision effects at long ranges. The Future Naval Force Study (FNFS) and the Future Surface Combatant Force Analysis of Alternatives (FSCF AoA) identified the requirement for future large surface combatants (LSCs) to be capable of hosting directed energy (DE) weapons, larger missiles for increased range and speed, increased magazine depth, growth in organic sensors, and an efficient integrated power system to manage the dynamic loads. DDG 51 is highly capable, but after over 40 years in production and 30 years of upgrades the hull form does not provide sufficient space and center of gravity margin to host future capabilities. To reset these design allowances for the future, requirements tradeoff and design studies were performed from FY 2018 to FY 2020 that considered modification of existing surface combatant and amphibious ships in addition to new concepts. These studies concluded that DDG(X) is required to deliver the necessary margins and flexibility to succeed the DDG 51 Class as the next enduring LSC combining the DDG 51 FLT III combat system elements with new hull form, an efficient Integrated Power System (IPS) and greater endurance, reducing the Fleet logistics burden. By including the DDG 51 FLT III combat system in a new hull, mechanical and electrical (HM&E) baseline, Navy is taking an "evolutionary" (vice "revolutionary") approach to the class. This is a critical lesson learned proven by the successful evolution of the original DD 963 Spruance design of the early 1970s that focused on lead ship HM&E capabilities and upgraded warfare capability over the next 50 years, including evolving DD 963 into the CG 52 class and incorporating the Aegis Combat System. In the early 1980's, the DDG 51 class applied a similar approach by incorporating the proven Aegis Combat System into a new hull form and subsequently executed upgrades over a period greater than 40 years before reaching hull limitations on incorporation of new, larger systems. When DDG(X) enters production, over 30 DDG 51 FLT III Ships will have been in production and early DDG(X) production transition will overlap DDG 51 FLT III production ensuring stability in the Large Surface Combatant industrial base. The CNO approved DDG(X) Top Level Requirements (TLR) in December 2020 that set the basis for a draft Capabilities Development Document (CDD) released in October 2021. Based on evolving threats and recent Battlegroup deployment feedback, the operational community revalidated the requirements and in August 2024 delivered revised TLRs. The updated draft CDD focuses on concept formulation, collaboration with DDG 51 shipyards in program planning, and targeted trade studies to achieve the CNO's cost, schedule, and performance targets.

Mission — OPLOG IPT Development source

Project 3389 - Develops enabling technologies for future and in-service afloat operational logistics and integrated supply systems; defines integrated combat logistics force and combatant logistics requirements; and conducts cooperative initiatives with acquisition programs, program sponsors, engineering managers, the Navy science and technology community, and Fleet customers. Operational Logistics Integration R&D (OPLOG) develops new logistics platforms, integrated cross-platform (i.e., applicable to more than one ship class/type) operational logistics and operational energy technologies and capabilities, as well as draft acquisition and operations policy ensuring future Naval systems leverage emerging logistic capabilities and technologies to provide operationally effective and efficient logistics delivery for both peacetime and wartime contested environments. Though the operational logistics family of systems touches all aspects of Naval presence and power projection, operational logistics capability and system interfaces typically have been left to individual acquisition programs to develop and resolve. Technology development is necessary to mitigate technological and operational risk before ship acquisition programs accept new technologies. This project provides a foundation for the transition and systems development of science & technology initiatives evolving from the Office of Naval Research (ONR) Power & Energy Future Naval Capabilities (FNC), Enterprise and Platform Enablers FNC, Seabasing FNC, and from other enabling Government, industry and academia concepts to the acquisition community. Thus, this project resources continued research and development of appropriate technologies with applicability to multiple acquisition programs and defines and matures performance and interface requirements for those technologies. This project continues to identify, develop, integrate, demonstrate, and transition logistics technologies to improve both the cost effectiveness of Fleet at sea logistics delivery in peacetime, as well as delivery capability effectiveness in wartime, through outreach, coordination and collaboration with industry, academia, Fleet, and Enterprise representatives. This project will continue to develop new logistics platforms, improved shipboard replenishment, transfer, and handling systems and components, as well as asset visibility and standardized packaging technologies. This project includes development of approaches to reduce operation and maintenance costs of, and energy consumption by the logistics Fleet. This integrated suite of developed capabilities will enable multiple ship types to leverage technologies common across DoD (Joint) and commercial transportation networks to provide a more affordable, energy efficient, and contested environment mission capable force. These capabilities and system-of-systems approach will be applied to concept development of future auxiliary force architectures.

Furthermore, the first DDG 51 FLT III ship entered production in FY 2017 and will not be able to accommodate any significant capability upgrades dues to SWAP-c constraints. The DDG(X) design tool is intended to be a common CAD (Computer Aided Design) and PLM (Product Lifecycle Management) hardware and software suite utilized by both Shipbuilders involved in the design and construction of DDG(X) ships. The DDG(X) design tool implementation will optimize the design work between the Shipbuilders and the Navy in a common data environment for 3D models, drawings, technical information, logistics, parts data, change management and configuration control. It is part of the overall DDG(X) Digital Environment and aligns with the DoN digital engineering strategy. The objective is to significantly reduce the design hours throughout the entire lifecycle of the ship from design, production and modernization by eliminating majority of duplicative work between the Shipbuilders.
