  • What is a submarine? A submarine is a

  • steel tube

  • in which we put three thousand pound hydraulic pipes,

  • 4,500 pounds per square inch high pressure air,

  • everywhere you can reach we've got 450 bold AC

  • power, 250 volt DC power we have

  • fans and pumps. We armed with the

  • weapons have almost unimaginable suspected power

  • we propelled with a nuclear reactor

  • and then we take it out and intentionally

  • sinked in salt water. That's not inherently safe.

  • The latest Los Angeles class fast attack submarine

  • is limited in its capability by only one thing:

  • how much food she can carry. Usually its 60 days supplies for her crew of almost

  • 150.

  • Getting them on board is a tricky maneuver

  • everything that enters the submarine goes through a narrow

  • hatch: food, men and weapons.

  • The low is a sealed world of work, drills,

  • sleep and more work in a cramped and sunless enviroment.

  • The Topeka is preparing to go out on patrol

  • only a handful of people know where she's going

  • and for how long she may be gone 12 hours

  • for six months patrolling close to Russia,

  • or lurking in the Red Sea. This is the world

  • the submariner regardless of his nationality

  • The former Soviet Union

  • still has the largest submarine fleet in the world

  • though much of it consists of aging diesel electrics

  • like this Foxtrot.

  • She is nearing the end of her useful life nonetheless

  • this patrol could take her far as the Mediterranean

  • and for six months

  • Returning from two months sea trials in the Atlantic

  • is her majesty's submarine (HMS) Unseen. She is also a diesel-electric

  • and is the Royal Navy's most modern non nuclear submarine.

  • Submarines have

  • always inspired both fascination and fear.

  • their movements remain closely guarded secrets

  • in the lives at the men on board is a

  • mystery. They all belong to a closed society

  • members have an exclusively male club.

  • Separation is a fact of life

  • shared by all submariners and their families

  • want a man goes on patrol he may as well be

  • on the moon

  • it's a continual cycle love separation and reunion

  • some say it's like a divorce every six months

  • others that it's a honeymoon

  • Not at myself but my views on the Navy so so as much concerned and

  • going to see I think to spur love affair pressure on

  • a marriage. ownership to see the ones I T A

  • the last minute safety at sea maybe 5-6 days with a little pools

  • we go out and spend six to eight weeks it's a in a BBC

  • BBC regular but it all the time you can come to the family car want to them

  • me there hardly the family hardly the children have to launch

  • I want to your own they really understand six months

  • put even have only gone for a week

  • then are gone for a few days in the store ask mom where's daddy

  • that sort of thing stand in front window where's daddy when she coming home

  • was dead you know her dinner he said and

  • you've seen for I am

  • he takes any kind

  • p

  • i like it

  • him

  • when his bold moves away from the dock a submariner enters a world which he

  • cannot share with anyone

  • except those around him by tradition

  • submarine service is the most secretive among the military

  • in any country

  • once the topeka reaches deep water of San Diego

  • she will die entering her true the first dog was frightening I mean a school that

  • Allah the some dreamworks a

  • put together without any died when she stood there and the of

  • afterward and festival out some control thank you this is wrong and I'm

  • backwards

  • and that goes down from within actually died after the Dec when your study on

  • course

  • merge Fisher static course worshipers I'm

  • operating a submarine

  • requires precision teamwork

  • the captain's orders are repeated and relate several times before being

  • carried out

  • it's part of a system of multiple checks

  • designed to eliminate possibility there merchant 150 be

  • online be nice

  • dying way the the Friday

  • to submerge ship a submariner must do what every surface sailor dreads

  • take water on board ballast tanks are flooded for extra weight

  • and diving plane steer the boat below achieving what's called

  • neutral buoyancy is a fine balance between submerging

  • and sinking thanks a lot wash nicer

  • up 33 down

  • 72 technically it would be possible to automate

  • or any of these functions 7 wanna submarine operators deboers 1500 feet

  • a minor mechanical problem could push it to crush on him go quicker to identify

  • emergencies signs computers cannot combat them

  • as in the cockpit of an aircraft there is no we're on our mistakes

  • seeing the foxtrot crew taker down you could be forgiven for thinking you are

  • watching

  • war two movie but once again rigorous

  • teamwork is everything more than any other branch

  • naval service each man relies absolutely on his crewmate to do his job correctly

  • submariners overall navy's know their lives depend on each other

  • whoever else maybe friend or foe they share a common enemy

  • the sub-mariner has only one enemy

  • and thats all-round him the immensely powerful

  • and utterly implacable C

  • banging against the whole and giving your position away

  • they call it angles and angles

  • to this day the US Navy will only admit

  • speeds in excess of 20 knots but it's accepted that boats like the Topeka

  • are capable of nearly twice this speed almost fifty miles per hour submerged
