## Summary

Project 2486 — BBG(X) Integrated Power Systems requests $251.0M in FY2027, 93% of the $270.0M requested for program element 0603573N — a new start, with no prior-year and no current-year money. 1 R-2A activity decomposes the request, 1 new this cycle. Industry is the largest named R-3 performer at $90.6M, 36% of the project's FY2027 R-3 total.

## What project 2486 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, 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.
