World War II museum ships suddenly feel less like history after a US submarine sank an Iranian warship

• A US Navy submarine sank an enemy ship for the first time since World War II in Operation Epic Fury.
• As naval warfare reemerges in combat with Iran, World War II museum ships are finding new relevance.
• Museum ships can provide rare glimpses into what similar modern ships and naval battles are like.

For Brian Auer, the operations manager at Historic Ships in Baltimore, the video of a US Navy submarine sinking an Iranian warship this week looked strikingly familiar.

"I saw the footage of that Iranian frigate getting torpedoed, and it looks like any picture I see from World War II of a similar attack happening," he told Business Insider of the video released by the Department of Defense on Wednesday.

Before this week's attack in the Indian Ocean, the last confirmed US Navy submarine to sink an enemy ship in combat was the USS Torsk, a World War II submarine that sank two Japanese vessels in 1945 before becoming part of the museum that Auer manages.

Since 1945, large-scale battles between warships have been rare. As naval warfare reemerges as a key strategy in Operation Epic Fury against Iran, museum ships that saw combat in World War II are finding new relevance, showing not just how naval war was fought, but how it might look today. Suddenly, the floating museums feel a lot less like history.

"Those of us who work on museum ships don't like war," Ryan Szimanski, the curator at Battleship New Jersey in Camden, New Jersey, told Business Insider. "In many cases, we work here to try and teach people about how awful wars were.

"However, the fact that the United States has fought a naval action — one of the first ones since World War II — is making museum ships like us relevant and part of the public discussion in a way that we haven't been."

Museum ships offer immersive experiences

There are around 75 World War II-era museum ships open to the public across the US. These decommissioned battleships, submarines, destroyers, aircraft carriers, and other vessels offer visitors the chance to climb aboard and explore the interiors themselves.

Guided tours, often led by Navy veterans with firsthand experience serving on similar vessels, take visitors through combat areas, such as torpedo rooms, gun turrets, and command centers.

Battleship New Jersey, for example, offers a rare look into Tomahawk cruise missiles as the first surface warship to carry them in 1982. The long-range missiles have also been used to sink Iranian ships during Operation Epic Fury.

"Because those are contemporary systems, to be able to see a Tomahawk missile, to be able to see Tomahawk missile launchers in a museum — there's only a handful of museum ships like us that you could come and see to get that experience," Szimanski said.

Some ships even offer sleepover experiences where guests can eat meals in the crew's mess and spend the night in sailors' bunks.

"It is highly unlikely that the average person will get the chance to visit an active-duty Navy ship," Szimanski said. "So to experience the conditions, to see what it's like to serve on a warship, particularly one that has seen combat, visiting a museum ship is your best chance."

'Remarkably similar' to modern Navy ships

While some technologies and configurations found in World War II submarines may be outdated, many aspects of how they operate remain the same.

"It's important to remember that the Navy, the military, all of us, operate in a world governed by laws of physics, and so there are some things that are just never going to change in how submarines work," Auer said. "If you walk through a modern Ohio-class, ballistic missile submarine, you're going to find things that are exactly the same, or done exactly the same way, on the USS Torsk. And what we can really show is where those things were first done, and why they were done that way, and why they are still done that way."

Modern submarines still appear "remarkably similar" to their museum counterparts, Szimanski said. The layout of submarines hasn't changed all that much since World War II. They largely still have the same spaces to eat, sleep, and fire torpedoes.

Auer says that when he leads tours of the USS Torsk for active-duty sailors, he often gets the response, "Huh, we're still doing it this way."

The biggest differences can be found in the ships' capabilities, Hugh McKeever, the shipboard education manager at the Independence Seaport Museum in Philadelphia, told Business Insider.

Diesel-powered submarines like the USS Becuna, which sank 3,888 tons of shipping in World War II before arriving at the Independence Seaport Museum, had to spend most of their time on the surface with only about 12 hours' worth of oxygen at a time. Today's nuclear-powered submarines operate with an unlimited fuel supply and can stay submerged for upward of six months.

"As far as going out to sea, their ability is pretty much limited only by food," McKeever said.

Overall, World War II-era submarines are less antiquated than one might assume. Some even still work. The USS Torsk's sister ship, the USS Cutlass, was commissioned in 1945, sold to Taiwan in 1973, and remains operational as part of the Republic of China Navy.

"These boats, to us, are so outdated that they're museums, but for the rest of the world, they're relatively advanced," Auer said. "They're still very capable of doing the function they were originally designed for. So, were they implemented by some foreign threat, they would be a threat."

Floating museums find new relevance

For ship museum curators, the resurgence of naval battles in the US war with Iran underscores the contemporary relevance of World War II museum ships and the battle stars they earned. McKeever, for one, anticipates getting more questions about torpedoes as the summer tourist season ramps up.

"For the US as a maritime power, the economic prosperity of the country is tied to the sea and the Navy," McKeever said. "Our museum vessels represent that constant need for change and growth as a country."

After all, as Szimanski noted, it was just days ago that no active US Navy ships had ever sunk an enemy warship — the only Navy ships that had fought a naval battle were all museum ships. Despite some rust and peeling paint, it seems they still have a lot to teach us.
