Battleships are almost certainly never coming back. The last ones, the U.S. Navy’s Iowa-class ships, were decommissioned in 1992, and every factor that led to their retirement has only intensified since then. The industrial base to support them is gone, the crew requirements are enormous, and modern anti-ship missiles can strike with a precision that makes thick armor far less relevant than it was in World War II. What navies are building instead are large, heavily armed destroyers and cruisers that carry the firepower of a battleship in a very different package.
Why the Last Battleships Were Retired
The U.S. Navy’s program management office laid out several concrete reasons against ever reactivating the Iowa-class ships, and those reasons have only gotten worse with time. The propulsion systems were described as old, unreliable, and potentially unsafe, with no skilled personnel left to maintain them. The Navy no longer has the capability to manufacture 16-inch gun components or ammunition. A 1981 inventory found roughly 15,500 high-explosive shells, 3,200 armor-piercing shells, and 2,300 practice rounds in storage. By 2016, the U.S. Army still held about 15,595 of those shells and was actively trying to get rid of them since the ships were permanently retired. No new production exists, and the factories and specialized tooling that once made giant rifled barrels and 20-inch-thick armor plate are long gone.
Reactivation would also require thousands of additional sailors the Navy simply doesn’t have. An Iowa-class battleship needed a crew of roughly 1,800. A modern Arleigh Burke-class destroyer accomplishes its missions with about 320 people. In an era of persistent recruiting challenges, manning a single battleship would consume the equivalent crew of five or six destroyers.
Even setting aside personnel, operating a battleship within a modern battle group would demand massive upgrades to communications, sensors, and self-defense systems. The Navy concluded that the cost to reactivate the ships to their 1990s capability would balloon further once modernization needs were factored in.
Modern Missiles Changed the Math
The core argument for battleships was always their armor. Iowa-class ships carried belt armor over a foot thick, designed to absorb hits from other battleships’ guns. But modern anti-ship missiles don’t play by those rules. They approach at sea-skimming altitude or dive from above at supersonic or hypersonic speeds, targeting specific vulnerable points rather than battering a ship’s side. A cruise missile doesn’t need to punch through a belt; it can strike the bridge, radar arrays, missile launchers, or engine intakes, all of which sit above the armored citadel.
Today’s naval doctrine prioritizes not getting hit at all. Ships survive by detecting threats at long range, jamming their guidance systems, and shooting them down with interceptor missiles and close-in weapons. Armor is dead weight that slows a ship down and costs tonnage that could carry sensors and weapons instead. A modern destroyer’s layered defense system, combining radar, electronic warfare, and multiple tiers of defensive missiles, provides far better survivability than steel plate against the threats that actually exist today.
The Shore Bombardment Gap
The one role where battleship advocates still make a case is naval gunfire support, the ability to pound targets on shore with sustained, high-volume fire. When the Iowa-class ships retired, the Navy acknowledged that the shift away from large-caliber guns had eroded its ability to support Marines fighting on land. Congress directed the Navy to establish a research program specifically to address this gap.
That gap still exists. A RAND Corporation assessment found that formal requirements for naval surface fire support have been poorly defined, with the Marine Corps never fully specifying what it needs from the Navy. Sensor-to-shooter timelines are too slow for a fluid battlefield, and the Navy has underinvested in the volume of munitions needed for sustained bombardment. Ships’ magazines are too small for prolonged fire support, and relying solely on high-explosive rounds limits effectiveness against maneuvering enemies.
But the solution isn’t to bring back battleships. RAND’s recommendations point toward lighter, longer-range munitions, unmanned fire support platforms, larger magazines on existing ship designs, and even additive manufacturing to produce gun ammunition at sea during high-use periods. These approaches solve the fire support problem without the enormous cost and vulnerability of a 58,000-ton warship sitting close to shore.
What’s Replacing Them
The Navy’s answer to the demand for bigger, more powerful surface ships is the DDG(X), a next-generation destroyer designed with significantly more capability than current vessels. It will displace roughly 50 percent more than today’s Arleigh Burke-class destroyers, with more space, electrical power, and cooling capacity to support weapons that don’t exist yet, including directed-energy weapons like high-powered lasers.
The DDG(X) baseline design includes 96 vertical launch cells for missiles, with the option to swap 32 of those for 12 large missile cells capable of firing bigger, faster, longer-range weapons. There’s also a planned option for an additional hull section called the Destroyer Payload Module that would add even more capacity. This is the modern version of what a battleship once provided: the ability to deliver overwhelming firepower. It just comes from missiles and energy weapons rather than massive guns.
Other navies are following the same path. China’s Type 055, which Western analysts classify as a cruiser despite China calling it a destroyer, carries 112 vertical launch cells and advanced radar systems. It has been described as placing China’s navy among the world’s top naval services. These large surface combatants represent the evolution of the battleship concept: maximum firepower in a single hull, but built around missiles, sensors, and electronic warfare rather than armor and guns.
Could a New Battleship Be Built From Scratch?
Setting aside reactivation, some enthusiasts ask whether a nation could design a brand-new armored warship with modern weapons. Theoretically, yes. Practically, it would make no sense. The tonnage devoted to armor would be better spent on additional missile cells, more powerful radar, or a larger electrical plant to run directed-energy weapons. Every ton of steel plate is a ton that isn’t contributing to the ship’s ability to detect, track, and destroy threats at range.
The economics are also prohibitive. The DDG(X) is already expected to cost about 22 percent more than the current top-of-the-line destroyer, according to Congressional Budget Office estimates. A ship with battleship-scale armor on top of modern systems would cost dramatically more while offering no clear tactical advantage. Navies worldwide have consistently concluded that the money is better spent on more numerous, more capable ships that can spread across a wider area.
The battleship era ended not because the ships stopped being impressive, but because the nature of naval combat changed around them. Precision-guided weapons, satellite targeting, and electronic warfare made the gun duel between armored ships obsolete. Nothing in current military technology or strategic thinking suggests that trend will reverse.
