The introduction of women on U.S. fleet submarines is but one change lurking for the venerable all-male "bubblehead" fraternity. Many are not happy, according to a report by the Washington Post.

Some retired vets and active sailors lament that female sailors will invariably become pregnant, potentially compromising missions during which submarines can remain submerged for months at a time.

Others complain that submarines are not built for the mixing of the sexes, given the tight passageways, shared berths and lack of privacy.

Navy officials, however, continue to be confident that the introduction of women, the slated smoking ban and the 'Don't Ask, Don't Tell" turnaround will be absorbed by the hallowed 'Silent Service' with little disruption.
