On December 22, 2025, President Donald Trump announced the most ambitious—and controversial—naval project of the 21st century: the Trump-class guided-missile battleship (BBG).1 Positioned as the crown jewel of the "Golden Fleet" initiative, the lead vessel, USS Defiant (BBG-1), represents a radical departure from decades of naval architecture, aiming to resurrect the prestige of the battleship for the era of hypersonic and directed-energy warfare.2

While the administration touts the class as an "unparalleled statement of American strength," naval analysts are divided on whether these 35,000-ton behemoths are the future of maritime dominance or a multi-billion dollar "Zumwalt-sized" gamble.

Capabilities: The Arsenal of the Future

The Trump-class is designed to be the most heavily armed surface combatant ever constructed, dwarfing the current Arleigh Burke-class destroyers by nearly triple the displacement.3

  • Strategic Firepower: The centerpiece of the ship’s offensive suite is the integration of Conventional Prompt Strike (CPS) hypersonic missiles.4 With 12 dedicated large-diameter tubes, the ship can strike targets thousands of miles away at speeds exceeding Mach 5.
  • The Nuclear Return: For the first time in generations, the U.S. Navy will field a surface-launched nuclear deterrent.5 The class is slated to carry the Surface-Launched Cruise Missile-Nuclear (SLCM-N), adding a visible sea-based leg to the nuclear triad.6
  • Directed-Energy & Railguns: Moving beyond traditional gunpowder, the Trump-class is designed to house a 32-megajoule electromagnetic railgun and high-power lasers (ranging from 300 kW to 600 kW).7 These systems aim to provide "limitless" magazines for missile defense, utilizing the ship’s massive electrical grid to intercept incoming swarms.
  • Command and Control (C2): With its massive frame, the ship serves as a floating headquarters. It is designed to act as the "quarterback" for both manned carrier strike groups and the Navy’s burgeoning fleet of unmanned surface and undersea vessels.8
  • Aesthetic Design: In a unique move, President Trump has indicated personal involvement in the ship's design, emphasizing that the vessels must be "best-looking" and "imposing," criticizing the "ugly" stealth profiles of previous generations like the Zumwalt class.9

Shortcomings: The "Steel Ceiling"

Despite the formidable specs, the Trump-class faces significant headwinds that could stall the program before the first hull is even laid.10

  • The Cost Bottleneck: Initial estimates place the cost of a single Trump-class battleship between $10 billion and $15 billion.11 In a fiscal environment where the Navy is already struggling to fund the Columbia-class submarines and Constellation-class frigates, many fear this "Golden Fleet" will bankrupt other vital programs.
  • Technical Overreach: The reliance on unproven technologies—specifically the railgun and high-output lasers—evokes memories of the Zumwalt program, where technological complexity led to massive cost overruns and the eventual truncation of the class.12 Barrel erosion in railguns remains a significant engineering hurdle that has yet to be solved for sustained combat.
  • Industrial Capacity: U.S. shipyards are currently at a breaking point, facing severe labor shortages and aging infrastructure.13 Critics argue that building 35,000-ton steel hulls will distract from the more urgent need for a high-volume "low-end" mix of smaller, more numerous vessels to counter China’s massive fleet.
  • The "Large Target" Problem: In an age of "carrier-killer" missiles and drone swarms, some analysts argue that putting so much capability into a single, massive hull creates a "prestige target" that is too valuable to lose. If a $15 billion ship is disabled by a $50,000 drone swarm, the strategic exchange ratio becomes catastrophic.

Conclusion

The Trump-class battleship is more than just a ship; it is a shift back to "Big Deck" diplomacy and a bet that massive, visible firepower can deter adversaries more effectively than stealth and distributed lethality. Whether the USS Defiant becomes the vanguard of a new American century at sea or a cautionary tale of industrial overreach will depend on the Navy's ability to bridge the gap between 20th-century aesthetics and 21st-century technology.
