## What project 0413 buys

The Guided Missile Battleship (BBG(X)) program supports the expansion and modernization of the Nation's large surface combatant fleet, reinforcing maritime dominance. The Battleship is based on the validated requirement for high-end surface capability directly supporting the Navy Warfighting Concept (NWC) and Expanded Maritime Maneuver (EMM) that cannot be met by current fleet assets. Adding capability at the highest end of the Golden Fleet high-low mix, the Battleship's primary role is to deliver high-volume, long-range offensive fires and serve as a robust, survivable forward command and control platform. The expanded size and energy density of the new Battleship provide critical advantages for future naval warfare, offering a future-proof platform with distinct capabilities that enhance deterrence. Its advanced systems will enable true long-range strike with hypersonic weapons housed in new, larger vertical launch systems. Vastly increased power generation, managed by a sophisticated integrated power system with high-capacity energy storage, will support mission-critical directed energy weapons like high-output lasers and electromagnetic railguns, reducing reliance on costly single-use munitions. Furthermore, its advanced naval gunfire offers cost-effective options for strike and defense, and its capacity to embark a fleet command staff enhances survivability by putting commanders closer to the fight. As a flexible command-and-control platform for both manned and unmanned platforms, including the Medium Unmanned Surface Vessel (MUSV), the Battleship can lead a Surface Action Group, integrate with a Carrier Strike Group, or operate autonomously to secure critical sea lanes. To overcome the capacity limits of the Arleigh Burke-class destroyer and the capability compromises of the planned DDG(X), the Battleship is designed specifically to accommodate these advanced weapon systems. The ship's architecture provides the foundational space, weight, power, and cooling for five large weapon stations, enabling the integration of large-format missile launchers, railguns, and high-energy lasers that cannot be incorporated within legacy platforms. The design ensures room for future technological advancements and sends an unmistakable signal of American resolve, inspiring confidence in allies and fear in adversaries.

**R-3 lines of work:** Product Development; Test and Evaluation; Management Services.

### BBG(X) Design and Analysis — NEW START

In FY 2027, the BBG(X) program will execute the Preliminary Design phase. This phase will mature the Initial Baseline design by developing the initial ship specifications and completing the selection of major system components. The team will focus on accelerating the design timeline through decisive action in support of design…

### BBG(X) Test and Evaluation — NEW START

**FY2027 planned work.** In FY 2027, the BBG(X) Test & Evaluation (T&E) program will begin Live Fire Test & Evaluation (LFT&E) Event and Survivability Assessment M&S execution as well as planning for Developmental T&E (DT&E) and Operational T&E (OT&E) activities. These activities must be completed to ensure systems are properly verified and validated against requirements to support Battleship Initial Operational Capability. General T&E major activities will include standing up the BBG(X) T&E Working-level Integrated Product Team (WIPT) to establish relationships and expectations within the program and holding the initial T&E Requirements Resource Board (TERRB) to ensure the Navy has sufficient resources to execute the T&E Strategy. DT&E major activities will include planning for Hull Form and Integrated Power System Developmental Tests (DTs) and preparations for their respective DT Readiness Reviews (DTRRs) to verify the systems are designed to meet requirements, meet contractual specifications, reduce technical risk, and are mature enough for production. Program Office Instructions will be created to regulate the DTs. LFT&E major activities include creation of a LFT&E Management Plan, LFT&E Critical Issues, and starting M&S for the initial BBG(X) Survivability Assessment Report (SAR) to include creation of a BBG(X) Survivability Model, System Deactivations, Equipment Model and Kill Criteria, Weapon Report Cards, and Weapon Hit Point Distributions. LFT&E events will be executed to close LFT&E M&S capability gaps identified during ship design. OT&E major activities include planning for Integrated Evaluation Framework and Early Operational Assessments to combine DT&E and OT&E activities to IT activities to the maximum extent possible, resulting in a more efficient use of funding and resources.

**FY2026 to FY2027 change.** FY 2026 to FY 2027 increased in the amount of $8.276M due to the expanded scope and accelerated schedule. The condensed construction time is in support of the Golden Fleet shipbuilding plan.
