As of earlier this year (2012) the U.S. Navy qualified its first female submariner, with several more in the pipeline.
However, for now (and likely the foreseeable future), female crew are limited to officers only, since they're afforded their own staterooms and the privacy concerns are reduced considerably.
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.
No sorry
They are allowed on all of them. They currently serve on all but the smallest ships that do not have accomodations for them such as Frigates.
No - the unique nature of SEAL missions has always excluded females from service as Navy SEAL's; however, women are allowed to serve on UDT teams.
Currently, women are not allowed to serve in the US Navy SEALs. However, there has been discussion about potentially opening up these roles to women in the future. As of now, women play critical roles in many other areas of the military, serving as pilots, engineers, medics, and in numerous support positions.
Females have been riding submarines for many years, but primarily only as riders (e.g., Contractors, Intelligence analysts, etc.). Up until recently, females serving aboard U.S. Navy submarines was restricted - however, with recent changes in policy, female officers will begin serving aboard FBM submarines within the next few years. Most navies with nuclear submarines (e.g., Royal Navy) don't allow women to serve aboard submarines due to the unique health risks that women are exposed to if serving aboard for long periods of time.

During WW2 the US Navy built 126 submarines.

As of recent reports, women make up about 20% of the U.S. Navy's submarine force, with numbers increasing since the integration of women into submarines began in 2010. The exact number can vary as personnel change, but the trend shows a growing acceptance and inclusion of women in this traditionally male-dominated field. Other navies globally are also working to integrate women into their submarine forces, though the numbers may differ.
Aside from nurses on hospital ships, the Department of the Navy began authorizing female sailors to serve aboard non-combat vessels during FY 1979. The first women reported aboard their respective ships by November 1, 1978.
