0:00Right now, deep underwater, there are killers -  submarines with the power to change the world. The  
0:05men aboard them spend months at a time in a metal  can, hoping they’ll never receive an order that  
0:10means only one thing… the end of civilization. The crews that work on the Ohio Class Boomer subs  
0:16are some of the most highly trained sailors in the  U.S. military. What they do, where they go, even  
0:22what a day at work is like, is a tightly guarded  secret. For roughly 70 to 90 days at a time, they  
0:28vanish, not even able to tell their spouses or  girlfriends where they are or what they’re doing. 
0:32Ask one of the crew what their job is,  and they’ll tell you they preserve peace.  
0:36It sounds good on paper. But they know that if  they ever use the weapons on board, they won’t  
0:41be going home. There won’t be a home left. But beyond threats of global destruction,  
0:46the job itself is incredibly hard. These boats  often operate hundreds of meters below the  
0:50surface. The men are trapped. A crew of around 155  spends weeks at a time in cramped areas surrounded  
0:57by pipes and dials, an endless array of switches  and gauges. And they’re never far from a weapon.  
1:03Where they sleep, eat, or use the toilet, missile  tubes are just feet away. When they retreat to  
1:08their curtained-off bunk, they're never sure if  they will be jolted awake by a drill - or worse,  
1:13the news that the homeland is under attack. On this submarine, the work never stops. 
1:18The crew are usually woken around 45 minutes  before their shift begins. They get dressed,  
1:23and have their first meal of the  day. Whether that’s breakfast, lunch,  
1:26or dinner will depend on the rotation.  After 6 hours, they’ll be relieved,  
1:30but after more food, there might be cleaning  duty, maintenance, training, or meetings. 
1:34On paper it’s six hours on, six hours off  - but in reality, you’re never really off. 
1:39By the time they get back to their bed, they  are exhausted. Six to as many as 34 men will  
1:44sleep in three-tier bunks that are stuffed  together in a room like sardines in a tin,  
1:49their worldly belongings packed into  a small shelf. Only the captain and a  
1:53few officers have a private cabin. For the  rest, subs make prison cells look spacious. 
1:58Privacy ends at the curtain. There’s no space for a gym,  
2:01so men do pullups on pipes or push off against  walls. They find spaces to lift dumbbells and use  
2:07exercise bikes and treadmills. The crew’s mental  health is a top priority, the reason why the food  
2:12on Boomers is better than anywhere else in the  US military. The Navy chefs cook up a storm,  
2:17feeding men in what looks like a diner from the  1950s. It’s one of the only places where they  
2:21have space to move around freely and chat about  life. Burgers, apple pie, Italian food, and tacos,  
2:27the crew of the Boomers is well taken care of. Still, you can forget about spending time alone  
2:32with your thoughts. One man’s snoring  is another man’s nemesis. Thankfully,  
2:36the men work in rotation – about a third of the  crew will be asleep at any given time – making the  
2:40sleeping quarters less noisy and more private. At  the end of the room is the bathroom, shared by all  
2:45the men in those sleeping quarters. The “submarine  shower” usually means getting wet for 10 seconds,  
2:50turning water off to soap up, then turning it  back on for 10 seconds to rinse, using around  
2:554 gallons of freshwater total for a 1–2-minute  shower. Taking a long time in the shower or on the  
3:01toilet isn’t tolerated. On a submarine, you follow  the rules – it’s all for one and one for all. 
3:07That’s why the men maintain good  hygiene standards. They have to. 
3:10Smelling bad or looking disheveled is bad for  everyone else’s morale. There’s a tiny space  
3:15where a crew member acts as the submarine barber.  These days, there are often women on board too,  
3:19but of course, they don’t sleep alongside the  men. Separate berthing areas are one reason  
3:23submarines were slow to use mixed crews, but  it’s still mostly a man’s world under the ocean. 
3:28Boomers are massive, multi-deck machines. The  upper levels house command spaces like control  
3:33and communications. The middle areas include crew  messes and living spaces. And the lower sections  
3:39are packed with engineering systems, missile  compartments, and propulsion machinery. When  
3:43the ship is ready to dive, the order will come to  submerge. The subs weigh thousands of tons – about  
3:4818,000 when submerged – but that doesn’t mean  they just sink. Filled with air, they’re buoyant,  
3:54displacing enough water to float like a steel  island. To submerge, large ballast tanks are  
3:58opened, and seawater floods in. That increases  the submarine’s density, and it can dive. 
4:04You obviously don’t want a submarine banking  too hard, or worse, losing control, but that  
4:09just doesn’t happen. Subs do sometimes perform  steep angles to test systems or in emergencies,  
4:15but anything over 30 degrees is extreme.  So, the added bonus about life on a  
4:19submarine is that you don’t get seasick. As for propulsion, they can reach about 20  
4:24knots submerged (23+ mph). The reactor produces  heat, and water becomes high-pressure steam.  
4:29That steam spins turbines, and those  turbines turn the submarine’s propeller,  
4:33pushing it silently through the ocean. The  steam is then cooled back into water and reused  
4:37in a closed loop. Because no oxygen is needed,  they can keep going indefinitely. Maintenance,  
4:43food stocks, and the crew’s sanity are the  reasons they come into port, not lack of fuel. 
4:48But what about breathing? Well, the nuclear reactor supplies electricity,  
4:52and that’s how a machine can split seawater into  hydrogen and oxygen – electrolysis. The oxygen  
4:58is released into the sub, and the hydrogen is  dumped overboard. Then you have machines that  
5:03remove carbon dioxide from the air using special  chemicals, so the crew doesn’t get poisoned. Subs  
5:09also carry backup oxygen in tanks or chemical  “candles” that can provide breathable oxygen. 
5:14Subs move through the pitch black of the ocean,  which can be brutal – months without sunlight or  
5:19wind on your face. But these machines are made  for stealth, not comfort. They glide through the  
5:24water, barely making a sound because of noise  reduction engineering. That kind of technology  
5:28doesn’t come cheap. Boomers cost around $2 billion  to build when the Ohio-class was first designed,  
5:34but that would be closer to $4 billion today. Part of that cost is their destructive  
5:38potential, but much of it is the technology  that allows them to navigate, detect, track,  
5:43aim, and survive - all while remaining  hidden from sonar, visual observation,  
5:47and just about anything else. In silent mode,  they’re even quieter - men aren’t even supposed  
5:52to talk loudly. There are times on a submarine  when all you can hear is the constant whirring  
5:57of fans or buzzing of electrical equipment. Other than the orders to end the world, the one  
6:02thing submariners fear is fire. Even a small fire  in such confined spaces can fill compartments with  
6:07toxic smoke - and there’s nowhere for it to go. If  a serious fire breaks out, there may be nowhere to  
6:13run. A blaze in one section of the boat could  damage propulsion, navigation, or life-support  
6:18systems, leaving more than a hundred people  trapped deep under the sea. 118 men were lost when  
6:23a fire broke out on the Russian nuclear submarine  K-141 Kursk in 2000, condemning it to the seabed.  
6:30The crew won’t feel scared when underwater, but  unfamiliar loud noises or the smell of smoke  
6:35will certainly get a man’s attention. And these aren’t regular submarines,  
6:39they’re nuclear ones. If a fire were to spread  into the reactor compartment, the very worst-case  
6:44scenario would involve radiation. As it stands,  though, crew on nuclear subs are not subjected to  
6:50dangerous levels of radiation. And fire and leaks  are highly unlikely because reactor spaces are  
6:55heavily isolated and have lots of safety systems  around them. Still, crew members are constantly  
7:00drilled on fire response and containment. Before a submariner can get the insignia of a  
7:05submarine to pin to their uniform, they must “earn  their fish,” also known as getting your dolphins.  
7:10That partly means every last one of them must  qualify as a first responder. Breaches, fires,  
7:15flooding, toxic gas, a man collapsing clutching  his chest, everyone onboard is expected to know  
7:20what to do. Not only will these sailors know  about nuclear propulsion and complex systems,  
7:25but they’ll also be able to step into the role  of medic or firefighter at the drop of a hat. 
7:30If things get serious, parts of the submarine can  be converted into a makeshift operating theater.  
7:35A Duty Hospital Corpsman, the Doc, will be on  board, but he’s not prepared to give you heart  
7:40bypass surgery. Anything serious will mean  the submarine has to surface or rendezvous,  
7:44something they really don’t like doing. A former  Boomer crewman said online that in the two and  
7:49a half years and five patrols he served, his  boat broke radio silence just once - when a  
7:54crewman developed appendicitis. Then there are  viruses, too, which on a submarine will be shared  
7:59around. One sailor said colds and other minor  illnesses cycled sometimes two or three times. 
8:05It’s not just physical issues you have  to worry about. Down here, even small  
8:09psychological problems have nowhere to go. Extreme confinement, isolation, artificial  
8:14lighting, and a massive lack of privacy can take  a toll on the mind. Mental health is a serious  
8:19concern for submariners. Especially among the  newbies, the risk of anxiety or depression is  
8:24high. That’s one reason selection standards  are so strict. Only a few thousand sailors  
8:28each year make it into the nuclear submarine  force. Even so, submarine crews are constantly  
8:33evaluated. Signs of serious psychological  distress are taken seriously – you really  
8:38don’t want a man losing his mind underwater.  If that happens, they’ll be disembarked at the  
8:42first opportunity and likely won’t ever come back. New arrivals, known onboard as “pukes,” or “nubs”  
8:48-non-useful bodies - are like children entering  a new world where the adults don’t pull their  
8:53punches. Each job is specialized, but every  submariner must understand how the entire ship  
8:58works. A torpedo technician won’t know the reactor  the way an engineer does, but everyone must  
9:02understand the basics of every system. The faster  you learn, the more respect you’ll get. That first  
9:07year is very tough, so you can forget having  much downtime and anyone treating you with kid  
9:12gloves. One former submariner put it like this:  “You are breathing my air, eating my food, and  
9:18filling my sanitary tanks. Get qualified, nub.” The reason for all this seriousness is obvious. 
9:24Submarines demand everyone works in tandem like  a finely-tuned machine. And let’s not forget that  
9:29Boomers are equipped with Trident II ballistic  missiles. Even way down in the ocean, those  
9:33missiles can reach targets around 7,000 miles  (11,265 km)away. Launch authority rests entirely  
9:38with the President, and after that, everyone has  a job to do. The Commanding Officer cannot act  
9:42alone; there are strict nuclear safeguards  and authentication procedures - so multiple  
9:47officers work together before anyone dies. Someone will announce, “Standing by for fire  
9:52order,” followed by confirmations such as,  “Concur with fire order.” These sequences  
9:56are practiced again and again, something no  one on board ever wants to perform for real. 
10:01After launch, there’s nothing to  do but stay submerged and wait. 
10:05But if a strike ever did go ahead, a Trident II  would reenter the atmosphere traveling as fast  
10:10as Mach 24, or over 18,400 miles per hour (29,611  kph). It will then break up into eight independent  
10:16reentry vehicles, and each of those carries  between a 100 and 475-kiloton nuclear warhead. 
10:23Within one minute, the commander could order a  salvo of 192 warheads, enough to turn 24 cities  
10:28into ruins. Meanwhile, the men on that submarine  will know that for everything they are firing,  
10:33Americans in their homes will no doubt  be receiving. Between all the Boomers,  
10:37there are around 240 missiles active with  almost 1,100 warheads - enough destructive  
10:42power to pull the plug on civilization. To get through stress like that,  
10:46many men spend months underwater like monks  in a monastery. There’s certainly no social  
10:50media for distraction. For fun, you might play  cribbage and chess over dinners of salmon and  
10:55oxtail soup. There will be books to read, too,  usually in your bed under a fluorescent light.  
11:00When movies are scheduled to be watched in the  mess, it’s often through a projector, and the  
11:04films get repeated. Free time on the submarine  is not like having time off in the regular world.  
11:09It’s like living at work, and you’re expected  to be ready 24 hours a day if called upon. 
11:13As one Boomer crew member said online, time off  needs to “be taken with a pinch of salt.” At  
11:18some point, there’ll be morale-boosting  events, maybe pizza or Surf &Turf day,  
11:22maybe even frozen lobster. They work hard,  but they’re treated well for having one of  
11:26the most important jobs in the world. And at least they can tell their wife  
11:30and kids they’re alive. Submariners are allowed to  send emails home to let family know they’re okay,  
11:35but those messages are heavily monitored. On  missions, there are no emails. If tension builds,  
11:40they exercise. If they’re overwhelmed, they often  keep it to themselves, but ships usually have a  
11:45spouse’s group or someone who can counsel them.  This constant pressure is one reason submariners  
11:50will tell you that being likable and able to make  people laugh is one of the most valuable traits  
11:54you can have underwater. Funny men are like gold  dust. As the U.S. Department of War once put it,  
12:00these people “depend on each other.”  Submarine life is absolutely not for  
12:04everyone, but if you’re suited to it, the  camaraderie is something you’ll never forget. 
12:08Boomers don’t stop working when they reach  port. Each submarine has two full crews,  
12:12known as Blue and Gold. While one crew disembarks  after a patrol, the other is already preparing to  
12:18take over the same boat. The handover is quick.  Supplies are restocked, maintenance is handled,  
12:22and within weeks, the submarine heads back out  - often with an entirely different crew aboard. 
12:27The mission never really  ends; only the people rotate. 
12:30Still, after 70 days aboard, no matter  how much you like your fellow sailors,  
12:35you’ll be desperate to arrive in port. Civilian  life feels strange after months of confinement  
12:39and buzzing sounds in your ears. Driving can  be dangerous at first because their eyes are  
12:43accustomed to tight, artificial spaces. The  brain slows down on the submarine because  
12:47it has adapted to an environment with far  less stimulation than the outside world.  
12:51They ease themselves back slowly into  a world that they hope to God they’re  
12:55never asked to fire their nuclear weapons at. Now go check The Greatest Submarine Rescue
