DDG(X) Destroyer Design Gets a Major Overhaul at SNA 2025.


The DDG(X), unveiled with updated details during the Surface Navy Association (SNA) 2025 symposium, represents the U.S. Navy’s most advanced approach to surface combatant design. This next-generation destroyer is intended to replace the Ticonderoga-class cruisers and complement the latest Arleigh Burke-class destroyers, addressing emerging threats and adapting to the technological demands of the 21st century.

A key revelation at SNA 2025 was the removal of the traditional 5-inch Mark 45 Mod 4 gun, a departure from earlier design concepts. This omission highlights a shift in priorities, focusing on advanced weapons and modularity. The vacated space may accommodate larger Vertical Launch System (VLS) cells or directed-energy weapons, signaling an emphasis on long-range engagement and integrated missile defense. The updated VLS configuration includes new, potentially larger-diameter cells capable of supporting advanced weapon systems like hypersonic missiles or Lockheed Martin's G-VLS modules, ensuring readiness for both offensive and defensive missions.

The ship’s superstructure has been redesigned for improved stealth and sensor integration. Modifications include refined radome placement above the bridge, adjustments to exhaust funnel arrangements, and potential repositioning of electronic warfare arrays such as the AN/SLQ-32(V)7. These changes are aimed at reducing radar cross-section and enhancing survivability in contested environments. The overall design optimizes the vessel's ability to operate in high-threat zones while maintaining cutting-edge electronic and sensor systems.

Power generation is a cornerstone of the DDG(X) program. The Navy is integrating an advanced Integrated Power and Energy System (IPES) capable of producing up to 40 megawatts of reserve power. This capacity is crucial to support the next generation of energy-intensive systems, including directed-energy weapons, advanced radars, and electronic warfare systems. This focus on power aligns with future needs, allowing the platform to adapt as technology advances over its lifecycle.

Strategically, the DDG(X) is tailored for an environment dominated by peer competitors such as China and Russia. Its enhanced capabilities, including directed-energy weapons and hypersonic missile compatibility, will allow it to counter modern threats like anti-ship missile swarms, hypersonic weapons, and advanced electronic warfare tactics. The ship is designed to ensure versatility across multiple domains, from blue-water operations to contested littoral zones.

The timeline for the DDG(X) reflects its importance to fleet renewal. Construction is set to begin in Fiscal Year 2032, with an intentional overlap between its production and the last Arleigh Burke Flight III destroyers to sustain industrial momentum and workforce stability. This dual-path strategy ensures a smooth transition while mitigating risks associated with adopting a new ship class.

The DDG(X) also incorporates modularity, emphasizing future-proofing. This approach allows for incremental upgrades in weapons, sensors, and systems as new technologies emerge. The ship’s architecture is designed to remain adaptable over decades
