What if the mighty Spanish Armada of 1588 met a modern U.S. Navy submarine? In this episode of Two Brain Cells, the USS Seawolf—a stealth nuclear attack sub—faces 130 wooden warships and 30,000 men armed with cannons and sails.

Armed with Mark 48 torpedoes, advanced sonar, and centuries-ahead stealth tech, the Seawolf strikes from the deep, turning the “Invincible Armada” into chaos. Watch as 16th-century galleons crumble against modern underwater firepower.

00:00July 1588. 130 Spanish warships sail toward England's shores under the command of King
00:07Philip II with 30,000 men and what was supposed to be enough firepower to blast Queen Elizabeth
00:14I off her throne forever. While they would eventually lose to the English, the Spanish
00:20Armada was the biggest naval fleet of the time and was considered the Invincible Armada.
00:26Now, sure, the English don't need saving, but just for the fun, let's change one thing.
00:32Lurking beneath the waves sits something that shouldn't exist for another 400 years,
00:37the USS Seawolf, a nuclear-powered attack submarine from the 90s armed with enough
00:42torpedoes to sink a fleet and technology to make Renaissance warfare look like a food fight.
00:48So what happens when the most advanced submarine ever built faces off against the pride of Spain's
00:53golden age navy? Let's find out. The USS Seawolf is 353 feet of pure democracy that costs more to
01:03build than Spain's entire Armada. Its teardrop hull slices through water at roughly 40 miles per hour
01:09underwater, faster than most Spanish ships could go with a hurricane in their sails. The USS Seawolf is
01:15packing 50 weapons in its torpedo room, including Mark 48 torpedoes that can literally break a ship
01:21in half from 20 miles away. Each torpedo carries 650 pounds of high explosive and travels at 55 knots,
01:30guided by onboard sonar and a silicon brain, two technologies the Spanish of 1588 could never
01:37comprehend. Also onboard is a nuclear reactor that produces 200 megawatts of power, enough to run a
01:44small city and never needs refueling. While Spanish ships depend on good weather and have to resupply
01:50every few weeks, the Seawolf can stay submerged for months, limited only by how much beef jerky the crew
01:56packed. Its sonar arrays can hear a shrimp sneeze from 50 miles away. And remember, we're in 1588 when
02:04long-range detection meant a guy with decent eyesight up in the crow's nest. This is basically cheating.
02:10The sub knows where every Spanish ship is before they even know there's an England to invade.
02:17Wrapped in anechoic tiles that absorb sound, the Seawolf is impossibly quiet. To the Spanish Armada,
02:24it's invisible. Across the ocean, Philip II has sent the Invincible Armada, 130 ships including massive
02:33galleons like the 1,000-ton San Martin bristling with bronze cannons. These floating fortresses carry
02:402,500 guns total, though most are tiny anti-personnel weapons that are rendered useless against the
02:46submarine. The Spanish fleet sails in a defensive crescent formation perfected over decades of warfare. The plan is
02:53to get close, grapple enemy ships, and unleash 19,000 soldiers trained in hand-to-hand combat who have just
03:00conquered half of Europe. Leading this wooden behemoth is the Duke of Medina Sidonia, a competent
03:06administrator who gets seasick and has never commanded a fleet before. Because apparently
03:12Spain thought invading England was a good time for on-the-job training. Supporting the Armada are
03:17the best sailors and soldiers of the Spanish Empire. These men conquered the Aztecs, dominated Italy,
03:24and control more of the planet than anyone else in 1588. They're tough, experienced, battle-hardened,
03:30and completely unprepared for what's coming. As dawn breaks on August 8th, the Spanish fleet
03:36approaches gravelines recovering from last night's English fireship attack. They're scattered, missing
03:42anchors, but still confident. Considering they outnumber this new English fleet 130 to 1, who can
03:49blame them? Forty miles away, the Seawolf's sonar tracks over a hundred wooden contacts as they crash
03:55through the waves, making more noise than a kindergarten class. The submarine goes toward
04:00them at 20 knots, silent as death. The torpedo room crew loads the first Mark 48 into tube one.
04:08At 0600, the Seawolf launches its first torpedo, a 3,400-pound smart weapon that streaks through the
04:14water at 55 knots, while its onboard computer analyzes the acoustic signature of its target,
04:19the flagship Sam Martin. The Spanish have no idea death is racing toward them at highway speeds.
04:26Hell, they don't even know what highway speeds are. Three minutes later, the torpedo detonates
04:30directly under Sam Martin's keel. The 1,000-ton galleon literally jumps out of the water,
04:35its spine shattered, and crashes back down to the water in two pieces. The Duke of Medina,
04:41Sidonia, and 400 men vanish into the channel in seconds. Before nearby ships can process what happened,
04:49three more torpedoes are already on their way. The Seawolf's crew works with practiced efficiency,
04:55and they have eight shots before needing to reload. Spanish captains see their flagship explode from
05:00below with no warning and no enemy in sight. Some scream about sea monsters, others fall to their
05:05knees in prayer. A few of the smarter ones just start sailing in the opposite direction.
05:10The sub systematically targets the largest and loudest of the fleet. Command ships and troop transports.
05:17Every three minutes, another torpedo launches, and every three minutes, another Spanish ship ceases
05:22to exist. It's tough to even call a battle. Within an hour, 15 major Spanish warships are gone,
05:29wiped off the face of the planet. Thousands of men who woke up expecting to conquer England are now
05:34asking their ancestors if they know what happened. The surviving Spanish try everything. They fire
05:39cannons randomly into the water, in other words, throwing rocks at a ghost. Some drop barrels of gunpowder
05:45overboard hoping to hit whatever demons lurk below. One desperate captain orders his men to stab the
05:51ocean with pikes. It goes about as well as you'd expect. The armada's famous crescent formation
05:58collapses faster than New Year's resolutions. Ships collide trying to flee. Captains order full sail
06:04north, south, anywhere but here. The most disciplined naval force in the world becomes a panicked mob.
06:10But even time-traveling death machines have limits. The Seawolf carries 50 weapons, not 130. After
06:16expending 30 torpedoes to sink the armada's core, it has to get selective. The crew targets ammunition
06:21ships, creating spectacular fireworks as powder magazines detonate. By noon, what started as an
06:27invasion becomes a rout. Spanish ships scatter to every point on the compass. Some make for the
06:33Netherlands, others for France. Most just want to go home and pretend this never happened. The submarine
06:38shadows the largest group fleeing north, occasionally launching a torpedo just to remind them the ocean
06:44hates them now. Spanish morale shatters. When sunset arrives, the Spanish armada as a fighting force no
06:51longer exists. 30 ships are confirmed sunk, another 20 are on their way, and the rest are running for
06:58their lives. The channel is littered with wreckage, barrels, and many very confused, or very dead,
07:04sailors. Spanish survivors who make it home tell wild tales of explosions from below,
07:10invisible demons, and England's pact with the devil himself. The Inquisition very possibly tries
07:16switching to Satanism to make a pact of their very own. Put simply, they won't ever know what
07:22hit them. Spain never attempts another major invasion of England, not because they can't build
07:27more ships, but because sailors literally refuse to enter English waters. The haunted channel becomes a
07:34permanent psychological barrier. King Philip II dies convinced God abandoned Spain, and the devil is
07:41in cahoots with Protestant England. The Pope issues several bulls condemning whatever infernal weapon the
07:47English used, which is awkward since the armada was destroyed before England heard they were on their
07:52way. England's naval reputation skyrockets without firing or shot, and the British Empire gets a 400-year
07:59head start on ruling the waves. The Sea Wolf, having deleted the Spanish Navy, likely with a few remaining
08:06torpedoes, could theoretically visit Spain and introduce the empire to democracy, but that's a
08:13different timeline. In our scenario, one submarine accomplished more in eight hours than the entire
08:1816th century. The Spanish Armada didn't just lose, it went extinct and left a trail of PTSD in its wake.
