What Senator Chambliss was talking about in the sexual assault hearing

The Senator claimed that a sizable number of women on the first mixed-crew deployment of an aircraft carrier became pregnant.

He may instead have meant the destroyer-tender AD 42 Acadia, which according to Wikipedia was the first mixed crew to serve during "wartime" (the Gulf War). It was nicknamed the "Love Boat" as about 10% of the female crew either embarked pregnant or became pregnant.

He then went on to suggest that further integrating women into combat roles would increase certain statistics, and wondered if the military had taught women what not to do (blame the victim, right?).
