How legendary battleships could come back, and why they won’t
The battleships of yore maintain a special place in the hearts of Navy enthusiasts — and it's easy to see why. Imagine the massive broadside salvos from the USS Iowa, each hurling 15 shells against an enemy force, smacking Communists with 18 tons of steel and explosives with each volley from as far as 20 miles away. Every few years, there's a new call to bring these behemoths back. Today, the Navy could, but they won't.
First, let's look at the role battleships were intended to play in naval warfare. These ships were floating fortresses, equipped with massive, long-barreled naval artillery. The idea was that these ships would form "battle lines" at sea. Battleships would line up, present their broadsides, and overwhelm an enemy force with firepower.
During the Russo-Japanese War of 1904-1905, battleships proved this strategy could work. The side that typically won a fight during that war was the one that got their battleships properly lined up against the enemy's formation first. The best success comes when one fleet can "cross the T," sailing their line of ships perpendicular to the front of the enemy line so they can fire all broadsides while only a few enemy ships can fire from forward turrets.
Japanese success added fuel to an arms race already playing out across the world's shipyards. The British launched the HMS Dreadnought in 1906, only a year after construction began. It was the most powerful weapon of war at the time and could fire 4-foot-tall shells at ranges of up to 10 miles.
It redefined naval warfare. All the powerful nations of the world began building copycats, leading to these ships taking on a huge role in World War I.
Except fights between battleships were actually fairly rare in World War I. This was partially because they cost so much to build that it was considered foolhardy to risk them when victory wasn't essential. Instead, battleships were often used to support operations on shore or to secure trade and supply lines.
But there were clashes between battleships, the largest of which was the Battle of Jutland in 1916 — by some metrics, the largest naval battle ever fought. Over 250 ships participated, including 50 battleships. The British had more and better ships, but suffered from poor gunnery and debatably poor tactics. Germany won the tactical exchange but Britain was victorious strategically.
It was the golden hour of battleships, still the kings of the ocean. But during World War I, a new weapon was introduced that would change naval warfare: the carrier. It would take decades for bombers to be effective weapons against capital ships, but the change was already underway by the time Germany invaded Poland, and arguably complete by the time Pearl Harbor was attacked.
Once naval aviation was capable of delivering repeated torpedo and bomb attacks hundreds of miles from their ship, the battleships' maximum ranges,, which hovered around 20 miles, made them too vulnerable for front-line fighting. Even super battleships, like the Yamoto, and their support vessels were forced to turn back when they thought they were facing even a single carrier fleet.
In fact, the Yamoto only fired its guns against a surface target in one battle before it was sunk in 1945. It was sunk by... let me check my notes here... carrier-based aircraft. But its sister ship, the Musashi... oh, that also saw minimal fighting before sinking due to damage sustained from carrier-based aircraft.
Instead, battleships took on a role supporting amphibious landings, raining steel on enemy positions as Marines and soldiers pressed ashore.
And that's the role battleships filled for decades, supporting landings in Korea, Vietnam, and even a fake amphibious attack in Iraq in 1991.
So, what role would a re-commissioned or newly built battleship play today? Not much of one. The Navy could re-commission a battleship, but they require tons of fuel and manpower — often needing over 1,500 crewmembers. And the best conventional naval guns still only shoot about 20 miles.
There is one game-changing technology that could resuscitate naval artillery: railguns. They can provide massive firepower at ranges of over 100 miles and speeds of over mach 7, all without conventional explosives that increase the risk of catastrophic damage during a fight.
It's not too hard to imagine a nuclear battleship with multiple railguns powered by the reactor and massive capacitor banks. But even then, the battleship wouldn't have the range to hit Chinese shore installations without venturing deep into the defender's anti-ship missile range.
So, the future is likely to lie in extended range missiles, carrier drones, and aircraft, all still capable of attacking targets hundreds of miles further out than even a battleship with a railgun could.
