Zitat:Report to Congress on the DDG(X) Programhttps://news.usni.org/2025/09/19/report-...gx-program
[September 19, 2025] [...]
In the program designation DDG(X), the X means theprecise design for the ship has not yet been determined. Asmentioned earlier, the Navy wants to procure the firstDDG(X) in the early 2030s. Procurement of DDG-51s—the type of LSC currently being procured by the Navy—wouldend sometime after procurement of DDG(X)s begins. [...] The Navy envisages the DDG(X) as having (1) Flight IIIDDG-51 Aegis combat system elements; (2) more growthmargin than the Flight III DDG-51 design, meaning morespace, weight-carrying capacity, electrical power, andcooling capacity (aka SWAP-C) for accepting additional orhigher-power equipment and weapons (including directed-energy weapons) over the ship’s service life; (3) anintegrated power system (IPS); (4) reduced vulnerabilitydue to reduced infrared, acoustic, and underwaterelectromagnetic signatures; (5) increased cruising range andtime on station; and (6) increased weapon capacity.

The Navy’s FY2025 30-year shipbuilding plan projectedLSCs being procured in FY2032 and subsequent years inannual quantities of generally one to two ships per year.The January 2025 CBO report estimates the DDG(X)’saverage procurement cost in constant FY2024 dollars at$4.4 billion—about 33% more than the Navy’s estimate(shown in the CBO report) of $3.3 billion. The CBO reportstates that “the Navy’s estimates for its destroyers implythat the DDG(X) would cost about 22 percent more than theDDG-51 Flight III but would have a full-load displacementthat was 50 percent greater than that ship. Such an outcome,however, seems unlikely given the history of surfacecombatants. [...]
The Navy’s proposed FY2026 budget requests $51.6million for Project 0411 (DDG[X] Concept Development)within Program Element (PE) 0603564N (Ship PreliminaryDesign & Feasibility Studies), which is line 46 in theNavy’s FY2026 research and development (R&D) account,and $81.9 million for “DDG(X) Power & Propulsion RiskMitigation & Demonstration,” which forms part of Project2471 (Integrated Power Systems [IPS]) within PE0603573N (Advanced Surface Machinery Systems) [...]
