Not bad at all, if you can imagine 30 people living in a 20′ x 20′ berthing area (or smaller) at sea. On land if you are E-4 and below you are assigned to barracks. At E-5 you share a room with another E-5 or above (at least for TAD assignments to specialty schools this was the case for me, and more often than not had the room to myself). Basically if you are at sea you have less space than a federaly incarcerated inmate is garunteed.
At sea E-7s and up have their seperate berthing area. And officers are two to a cabin, unless you are the CO or XO, or consideation is given for higher ranking CDR or LCDR to have their own cabin. This was on a guided missle cruiser and could be different on a carrier or other ship.
The matresses are about 4 inches thick, and just wide enough to have a a couple 2–4 inches on either side of you if you are in the center, which means you turn over in place in your rack to go from back to stomach or stomach to back.
Officers and E-7s and up had thicker mattresses, but the width was about the same. CO and XO had wider mattresses to sleep on, the equivelant of a twin sized mattress.
Food was excellent. Generally the order for food and accomodations and conditions goes like this. Air Force at the top, then Navy, then Army, then Marines at the bottom.
We had steak and lobster about once a month, unless we were doing special operations or at war. The mess cooks onboard were extrordinary and could put anything together from a ham and cheese sandwhich to a seven course meal for an officers ball, and more to include elaborate ice carvings and food arrangement and presentation on level with some of the best Japanese restaurants, if the formal occasion warranted it.
At sea laundry was handled by supply division, in port you are responsible for your own laundry.
On a sub, submariners hot rack. This means you take turns sleeping in shifts a rack assigned to two submariners. You put your own sheets blanket and pillow on the rack when you turn in, and remove them for the next guy when you go on watch. Since a warm body recently slept in that rack, you are never climbing into a cold rack, hence the name hot racking.
I understand food on submarines is excellent as well.
That’s all I can think of for now. If I think of anything else, I will add it later.
To add. The DOD has a deal with the MPAA (Motion Picture Association of America) so while out at sea or depoyed, box office movies are shown a few months before they are released in theatres everywhere.
