Female Submariners (Thought Experiment #05182010)

Submarines have transported some very unusual cargoes during times of armed conflict when ultimate stealth or absolute secrecy have been required. Other cargoes have been somewhat more difficult to explain: goat; motorcycle; contraband (you either know, or you don't).
.
Now, we have a new category to consider; in the future some U.S. submarines will officially embark women sailors. Historically, submarines have shared a casual affinity with pirate ships of yore which, if they ever embarked women, used them for purposes including cumshaw and barter.
.
U.S. women will not only serve in traditional naval officer roles, however, they will provide our submarines with a resource.
.
What additional benefit(s) will the presence of female crew on some U.S. subs provide, do you imagine? HINT: this guy dare not assign women to his submarine crews.
