"Some have become more critical than others; for example, the submarines. And that's the Ohio Class submarine that needs to be modernized. The air component also needs to be modernized. The B-52, as someone earlier pointed out, is an outdated model that was flown by the grandparents of people that are flying it now. And we need a serious modernization program as well on our silo-launched missiles. All three are critical for the defense of the country."
