IMAGINE 150 fraternity brothers packed into a container the size of a three-bedroom house. Announce you are breaking hallowed traditions by taking away their cigarettes and admitting women. Then lock the doors and push the container deep into the sea, for months at a time. This is what the US navy, after decades of contemplation and controversy, has decided to do with its submarine force, an elite fraternity of 13,000 active-duty sailors that has been patrolling the oceans for 110 years.
