SSGNs are Trident submarines converted to Tomahawk guided cruise missile systems used for danger close air support and lead combat bombardment (replacing the old Battleships since they can launch submerged and have much longer range - see janes Fighting Ships for details). SSBNs are Trident Ballistic Nuclear Boomers... SSNs are Nuclear Fast attacks that have a smaller contingent of weapons, torpedoes, anti ship missiles and also Tomahawks.
The typical mission of a Trident Nuclear Submarine originates in Kings Bay Georgia or Bremerton Washington or Fast Attacks home ported in Groton CT, Norfolk VA or San Diego CA transit to the Indian Ocean for Persian Gulf operations and replenish food supplies (fruits and fresh/frozen veggies, meats and canned goods and spare parts as needed at the coral island Diego Garcia, in the middle of the Indian Ocean owned and operated by the UK - some short shore leave volley ball, beer and shark proof pen enclosed swimming and some chilling and grilling in the Sun for 2 or 3 days and then a couple months on station providing cruise missile launch support to ground units and subsurface support to surface task forces. This is a 7/24/365 operational tempo in 3 round the clock shifts often hot racking 3 men to two bunks (the larger Tridents have more berthing which can be screened off with dedicated shifts for Female then Male use of heads and showers) sleeping in three 8 hour work shifts per day typically 8 on 12 off to account for eating, sleeping, showering, studying and now with women on board BANGING!!!
The dirty little secret is that in major surface ship deployments Aircraft Carriers and Resupply ships can forecast with near certainty that a number of the young lady sailors who depart for a long deployment will become pregnant during that deployment and now the Mothers and Kids are the responsibility of the DoD and US Navy - federal family medical leave act applies in most cases... you can't just strip a newborn from their mother and send the mommie bangler back to sea... females know this and take a mommie pass when ever they get bored or realize that they are on Military Deployment and not a Carnival Party cruise.
Of course the Military Brass try to forbid sexual relations "fraternization" between female and male crew-mates but being by and large the most intelligent and competent men in the US Navy just to get on subs - not a small proportion are natural alphas that women can not keep their hands off of ... I used to bring girl friends on board in port for dinner when there was a skeleton crew on board and throw a discreet quickie into them in various quiet locations on the boat before sending them home.
This will not be any different at sea on long deployments - unless they staff and send "female" post op trannie "women" or females with mandatory long term upper arm implants birth control or hard core Butch lezzies - I predict 25% to 50% of female crew members come back from long deployments pregnant by their own lizard brain's inability to keep their paws and pussies off of their target mega alphas they go to sea with and have a captive breeding audience with. Most military women are not 7, 8, 9 or 10's but 6's and below and many of the males are pure alphas and the best DNA semen sources these females could ever hope to hook up with. Many of the males will easily be white knighted into marriage.
Irony is this will have a severe negative impact on long term retention as the men's shore based wives do not want their senior male husbands cooped up at sea with young fertile though often fooglie females for 10 to 14 month deployments.
I also see a lot of work for the JAGs having to prosecute the ladies determined to win pussy poker by selling it like hair cuts on the side - at a "C" note plus per bang and the typical fooglie female on long term deployment comes home with ten to twenty grand in spending cash... and when the implant birth control wears off after a few months - and they are knocked up - who ever is the DNA Daddy match to the offspring wins the Dopey Dumb DNA daddy lottery and 22 years child support payments... Talk about force readiness chaos... the SJW Marxist Military Feminist pro LGBTQ lean in circles will of course blame all of this chaos as Alpha rape - the men being Alpha the females were biologically forced to mount them often and frequently on such long extended deployments and thus were subject to genetically motivated self initiated rape (otherwise know as consensual sex).
Can't imagine how many more things can go wrong - the chaos this will cause to force readiness and retention will make ISIS, Iranian, Chinese and Russian commanders smile with glee.
Naturally this modern Sheryl Sandberg Lean-in Circles trained male officer disagrees and poo poos the long term negative aspects of cooping up males and females for 12 month plus deployments inside Nuclear Sewer pipes at sea... go figure its the new obamanation military:

Notice how all of these executive DoD mandates are being enforced while Obama only has a year to go to destroy the Nation and long term Military readiness.
