There is no such thing as a safe submarine - there is a specific reason that submarine duty is strictly volunteer, and that submariners get hazardous duty pay, and it's due to the inherent increased dangers of submarine life, be it aboard a nuclear or diesel-electric submarine.
Without getting into classified specifics, there are significant increased health risks for women aboard boats as there are men, but the Navy doesn't specify those risks until the candidate has volunteered (and even then they don't say anything). Assuming you make it through the increased screening requirements (both psychological and physical), even then only about 5% of Navy volunteers are accepted as being qualified for submarine duty. Of that percentage, the average of those with health problems who serve aboard submarines is much higher than that of the regular Navy.
No, women aren't eligible to serve on board US Submarines.
It depends on the real question. If meant literally, then yes, women are allowed on submarines. They can visit some submarines. If the question is, "Are women allowed to serve/work on submarines?" then it depends on the country. In the Royal Navy (UK) they are not allowed to serve at present. The United States, however, is gearing up to allow some women officers to serve aboard U.S. Navy nuclear submarines.
Submarines typically use air tanks. Oxygen is very dangerous and very flammable. It's use is very limited on submarines for that reason.
No sorry
The Southern Ocean which surrounds Antarctica is dangerous for any ship, and especially for submarines, because of the high-volume of icebergs.
Submarines sink vessels by using stealth (hiding).
The duration of Dangerous Women is 2880.0 seconds.
Dangerous Women ended on 1992-01-01.
Dangerous Women was created on 1991-08-01.
Yes, there are always very small leaks . These are contained and not allowed to become dangerous.
If a women is assigned to a mission on the submarine then yes, but no they can't join the submarine service because of close quarters.
yes VERY dangerous
