Everyone thinks battleships are cool, right? Certain movies not withstanding…
When President Trump floated the idea of bringing battleships back into service, the response from the defense establishment was immediate and predictable: eye-rolling dismissal, lectures about “modern warfare,” and knowing smirks about nostalgia trumping strategy. The think tanks and defense journals lined up to explain why this was obviously impossible, impractical, and frankly embarrassing.
There’s just one problem: The more you examine the actual arguments, the less absurd it looks.
Starting with what Trump actually said, stripped of the mockery:
- Modern aluminum-hulled ships are vulnerable
- Guns deliver cost-effective firepower compared to missiles
- Battleships demonstrated effectiveness in the Gulf War
- China’s naval expansion requires a response that doesn’t bankrupt us
The “experts” immediately attacked the metallurgy comment. Aluminum doesn’t just “melt,” they said. Trump doesn’t understand materials science. Except…the U.S. Navy already agrees with him. That’s why the Arleigh Burke-class destroyers went back to steel construction in the 1980’s. The Falklands War demonstrated aluminum’s vulnerability to fire and battle damage. The 1975 USS Belknap fire drove the lesson home. The Navy’s own design decisions validate exactly what Trump said—they just said it in engineering reports instead of campaign speeches.
Now consider the actual strategic problem Western – and American – navies face: magazine depth. The Red Sea operations against Houthi drones and missiles – consuming an estimated 30 years of firing in 15 months – exposed a critical vulnerability. Modern warships carry perhaps 90-100 missiles in their Vertical Launch Systems. Once those are expended, you’re done. You’ve got a $2 billion ship that has to withdraw from the fight and spend weeks getting rearmed for anything beyond self-defense. Each Standard missile costs between $2 and 4 million. Each Tomahawk missile runs $1 and 2 million. Between October 2023 and January 2025, Navy ships fired more defensive missiles than they used in the three decades following Desert Storm. You can burn through a quarter-billion dollars in magazine capacity in a single extended engagement.
Compare that to a 16-inch gun. Modern rocket-assisted projectiles could reach 100+ miles. Each round costs perhaps $25,000-50,000 in current dollars — less if produced at scale. An Iowa-class battleship could fire continuously for days, delivering devastating effects on shore targets, surface vessels, and even providing anti-air support with proximity-fused rounds. The math isn’t even close: sustained and accurate fires at a fraction of the cost.
But what about vulnerability to modern anti-ship missiles? This is where the analysis gets interesting. An Iowa’s belt armor is 12 inches of hardened steel, backed by layers of structural protection. Modern anti-ship missiles — whether subsonic Harpoons or supersonic weapons — typically carry 500-1,000 pound warheads designed to penetrate thin aluminum hulls and detonate inside the ship. Against 12 inches of armor backed by compartmentalized protection? The penetration physics are completely different. Modern warheads might crater the armor, but achieving a “mission kill” (rendering a vehicle or craft unable to continue fighting, without destroying it) becomes vastly more difficult.
Survivability
Three cases are instructive in the vulnerability argument:
- When HMS Sheffield was sunk during the Falklands War in 1982, the warhead of the French EXOCET missile that struck it failed to detonate, or at least did not detonate properly. Instead, the Sheffield was irreparably damaged by fires started by the missile’s still-running engine
- In 1987, the USS Stark was attacked and struck by a pair of Iraqi-fired EXOCET missles. Prompt damage control prevented the ship sinking. After extensive repairs, the Stark returned to service, before being decommissioned in 1999, and scrapped in 2006.
- Later, in early 1988, the USS Samuel B. Roberts struck an Iranian naval mine while escorting a civilian oil tanker. The severely damaged ship required around a full year off repairs, before being returned to service.
- In 2000, the USS Cole was mined in the harbor of Aden, Yemen (although framed as a “bombing”, the actual attack counts as a ‘mining’ in naval terminology) by Al Qaeda terrorists using a massive IED. Following extensive repairs, the Cole remains in naval service.
- In contrast, there is the USS Nevada (BB-36), the only battleship on the list. Severely damaged by relentless air attack at Pearl Harbor, the Nevada was repaired and returned to service, serving throughout World War 2. At that war’s end, however, the ship was worn out, and thoroughly outdated, as it had originally been laid down in 1914…So, it was decided to use the old battleship as a nuclear target during Operation Crossroads, the first atomic tests at Bikini Atoll. The Nevada survived not one, but two, close range detonations, to such an extent that she had to be scuttled in 1948 by naval gunfire from the USS Iowa. That, however, was still insufficient to sink her, so she was finished off by an aerial torpedo.
Battleships, it would seem, are remarkably resilient.
Drones
The drone threat is real, but consider the defensive advantage: modern close-in weapon systems, electronic warfare, and updated radar married to a platform that can absorb damage and keep fighting. A kamikaze drone that could cripple an aluminum-hulled destroyer might barely scratch an Iowa’s main deck.
And, as operations in the Red Sea have shown, against actual warships – properly manned with trained crews – drones simply don’t present the threat that many believe to be real.
Manning – The Real Problem
The manning argument deserves serious consideration. Yes, the original crew was 1,500-1,800 sailors. But that was 1940’s technology with manual systems throughout. Selective modernization — updated damage control, automated fire control, modern propulsion plant controls — could potentially reduce crew requirements by 30-40 percent while maintaining the core advantages of proven mechanical systems over fragile digital networks.
Currently, while all services saw an increase in recruiting in the aftermath of Trump’s 2024 election victory, it remains to be seen if this increase will continue. The fact that the only real restriction on a “big-gun” battleship revival is whether the Navy can recruit enough personnel, is telling.
Conclusion
The real question isn’t whether battleships make technical sense. The real question is why the defense establishment is so hostile to the idea. And here’s where it gets interesting: battleships represent everything the current procurement system hates. Simple, proven technology. Conventional construction. Multiple potential suppliers. Long service life. Low-margin, high-volume ammunition. No proprietary software requiring endless updates. No justification for $100 million unit costs or trillion-dollar development programs.
Trump’s idea threatens a very lucrative business model. That’s why it sounds “crazy” to people with consulting contracts and board positions. To people actually concerned with sustainable naval power?
It starts looking remarkably sane.
