In the event you’ve ever watched the 2023 film “Oppenheimer,” there’s a scene the place the titular physicist watches troopers put bomb components into vehicles that then drive off into the horizon. Everybody is aware of what occurred after that: The U.S. dropped the atomic bomb on Japan, resulting in the tip of World Struggle II and the arrival of the nuclear age.
What isn’t proven is these bomb components reportedly first headed to Mare Island, a ship-building facility in Vallejo within the northern San Francisco Bay.
“These packages came into a small building. Nobody knew what was in them. There were armed Marines on all the rooftops around it, basically snipers,” says Kent Fortner, president of the Mare Island Historic Park Basis. “If you talk about the seminal event of the world in the last century, it might be the dropping of the atomic bomb. All that came to pass through right here on the island.”
This gripping nugget is amongst a whole bunch from Mare Island — regardless of its identify, it’s technically a peninsula — whose secrecy-shrouded previous dates from the Civil Struggle to its decommissioning within the Nineties. Greater than 500 numbered vessels have been constructed right here, and a thousand-plus extra overhauled. The primary commander was Admiral David Farragut of “damn the torpedoes, full steam ahead!” fame. Mare Island supported the Navy throughout each world wars and helped spy efforts through the Chilly Struggle through the use of nuclear submarines to faucet Soviet cables.
Even if you happen to don’t learn about its previous, it’s an interesting place to go to. Nearly 3.5 miles lengthy, it has a mixture of residential blocks with neocolonial houses and an industrial waterfront on the Napa River with functioning dry docks and “Star Wars”-scale cranes. There are scenic mountain climbing areas and a stunning park, that includes concrete bomb shelters and a nuclear Polaris missile aimed on the sky. Then there are the business enterprises that moved in as soon as the Navy left – artwork studios, tasting rooms for wines and whiskey and a brewery pouring Navy-themed suds in an outdated coal shed.
On a current afternoon, Lew Halloran is main a tour of the identical place he was stationed as a Navy man from 1989 to 1993. Mare Island’s historic basis gives these public excursions as a part of its academic programming, together with a speaker sequence with matters like the arrival of kamikaze pilots and a couple of,000 years of cryptography.
“The purpose of Mare Island was to maintain ships and to build ships. That’s why she’s here. And by the time we came up to closure, this yard could do anything,” says Halloran.
He gestures round: There was a store for bending and X-raying pipes and a foundry to solid propellers. A sawmill and a spot to calibrate periscopes. A espresso roaster and grinder that did nothing throughout World Struggle II however make 5-pound espresso cans for caffeine-deprived sailors. A paint manufacturing unit and laboratory the place analysis towards barnacles supposedly led to superglue. There have been craftsmen who might repair your picket leg.
“They could tear apart a boiler and put it together again from scratch,” says Halloran.
Close by, a siren out of the blue blares. Foghorn blasts and digital shrieks across the base give the uncanny impression the Navy by no means left.
“I don’t know what that means,” he frowns. “Nobody’s running, so I think we’re good.”

Mare Island’s bellicose historical past goes again to its identify. A Californio normal misplaced his prized horse overboard in 1835 and later discovered it wandering the peninsula – thus “Isla de la Yegua” or Island of the Mare. Through the Gold Rush, the U.S. authorities carved out land right here to guard the San Francisco harbor and its booming financial exercise. The primary ship constructed was the united statesSaginaw in 1859, a paddle-wheel gunboat used within the Civil Struggle to protect towards Accomplice marauders.
Admiral Farragut assumed management in these early years with the intention of nurturing a world-class shipyard on the traces of what existed on the East Coast. Issues started gaining momentum within the early 1900s, when the yard teamed up with Union Iron Works in San Francisco for armored ships, constructed forward of schedule and below price. Churning out destroyer escorts and submarine chasers elevated operations throughout World Struggle I, as a result of German subs have been sinking convoys left and proper.
World Struggle II noticed employment surge by means of the roof. In the end, some 45,000 folks labored right here, 1 / 4 of them girls.
“They were building submarines, all kinds of destroyers, and interestingly enough the biggest need in terms of number of vessels were landing crafts,” says Dennis Kelly, a basis board member who refilled nuclear submarine reactors right here through the Nineteen Seventies. “Mare Island built so many tank landing crafts that if you laid them out in row, it’d stretch for six miles.” (These automobiles’ components have been shipped by prepare from Colorado, and what decided their final dimension was the scale of a single railroad tunnel below the Continental Divide.)

Mare Island was one in all solely two public shipyards in America that constructed nuclear submarines through the Chilly Struggle. It hosted an “ocean-and-engineering program” that truly was a extremely labeled mission referred to as “Ivy Bells,” sunk deep within the Soviet Sea of Okhotsk.
“We had telephone taps that were 20 feet long and would take them by submarine with saturation divers to tap into undersea lines and record conversations,” Kelly says. The tapes have been swapped at Mare Island, then presumably flown in handcuffed briefcases again to D.C. for evaluation. “That program was credited for serving to finish the Chilly Struggle, as a result of we have been very hawkish about what the Soviets have been as much as and came upon they have been really extra anxious about us attacking them.”

The bottom was decommissioned in 1996 when a federal cost-benefit evaluation of navy bases discovered it missing for the post-Chilly Struggle age. There was a three-day “conversion” ceremony — the time period “closure” appeared too grim — with river patrol boats from the Vietnam period and Marines leaping out of a helicopter. However there’s nonetheless a lot to discover as we speak, and also you don’t even want a top-secret cross.
St. Peter’s Chapel is the oldest standing Navy chapel in the USA, devoted in 1901. It’s cozy, however the vaulted wooden ceilings and Tiffany stained-glass home windows lend a grand and Gothic air. Plaques pay tribute to each battle the Navy’s been in, from the Revolutionary Struggle to Vietnam, and are constituted of steel salvaged from notable ships — together with the united statesHartford, which Farragut steered by means of withering fireplace from Accomplice cannons in 1864’s Battle of Cell Bay (“damn the torpedoes!”). Tour the chapel on the second and fourth Sunday of the month, or take a tour by which your information might noodle on the outdated church organ.
Nature lovers may benefit from the Mare Island San Pablo Bay Climbing Path, a simple stroll close to the water that ought to get you thirsty for a beer later. And budding botanists will enjoyment of figuring out the individually tagged bushes throughout Mare Island that hail from far corners of the world: Canary Island Pine, Chinese language Pistache, Brazilian Pepper, Chilean Cleaning soap Tree.
Many of those owe their origins to Commodore James Alden within the late 1800s. “He told ship captains, ‘Wherever you go, pick saplings and send them back, and I’ll plant them here,” says Halloran. “As far as trees go, this island is supposedly the most biodiverse in the country.”

The alien species have led to at the very least one shut name, when a yard employee was clearing round an Australian bunya-bunya within the Sixties. “As I raked around the tree, I heard several loud noises coming from above me,” he remembers on a College of California gardening weblog. “I looked up and at the same time, a cone hit the ground about 10 feet away from me. I took the cone home with me and weighed it. It weighed 20 pounds.”
The Mare Island Artwork Studios is a unusual collective of painters and sculptors situated on the banks of the Napa River. It’s open to the general public each Sunday afternoon, when guests may meet a resident artist corresponding to Jean Cherie. She’s working to embellish the ferry dock on the outdated base with a 10-foot bronze statue of Wendy the Welder, the lesser-known cousin of Rosie the Riveter.
“Somebody said there’s not really anything that represents the women who worked here during World War II. I said, ‘Yeah, I can fix that,’” says Cherie.
As you may think for a spot stuffed with sailors, the ingesting tradition on Mare Island was strong in its day. Submariners who earned their “dolphins” – their hard-won insignia – couldn’t simply pin them on. They needed to first drop them right into a pint glass stuffed with each liquor conceivable and drink all of it the best way down. There was a bar named Chesty’s within the former Marine Corps barracks. It was named after Lewis “Chesty” Puller, a famously hard-ass Marine given to knowledge like, “We’re surrounded. That simplifies the problem.” (By firing in each route.)

This ingesting custom lives on on the Vino Godfather Vineyard, which serves flights and charcuterie, and the brand new tasting room of Redwood Empire Whiskey, with its Sonoma-style bourbon and Southern menu designed by an actual Kentucky colonel. Then there’s the Mare Island Brewing Co.’s Coal Shed Brewery, run by Ryan Gibbons and Kent Fortner – sure, the president of the Mare Island Historic Park Basis.
The taproom is sheltered in a hulking shed previously used to retailer coal for ships, together with Teddy Roosevelt’s Nice White Fleet, the battleships that circled the globe. When an electrician wired up the brewery, Fortner pointed him to a panel so massive, it appeared like its personal room. “He’s like, ‘Oh my God – there’s enough power here to power a battleship,’ and comes to the realization that we had enough electricity to run a small city off these things because that’s what these ships were.”

The brewing firm pays tribute to the native historical past with beers like Chesty’s Barrel Aged Stout and the porter Normal Order No. 99, aged in a bomb shelter and named for the Navy Prohibition directive banishing alcohol from bases. For grub, there’s a meals truck referred to as the Pie Wagon serving hand pies, crab muffins and fries. It’s named after a World Struggle II-era, luggage-toting kind of auto that delivered meals to almost 50,000 folks on base.
“Mare Island is the most unique and awesome branding opportunity I’ve come across,” Fortner says. “It’s a story that desperately needs to be told. It’s one of most important places on the West Coast in terms of naval history, and it impacted the world in so many ways.”
That features the small constructing used to retailer Oppenheimer’s atomic-bomb components and which is now not standing.
“There’s a taco truck that sits there where I eat about once a week,” says Fortner. “We call it the atomic taco truck.”
