I know when we bought our F-18s.... I think I have the figure here or something like that. When we bought our recent Chinooks, it was $1.2 billion to buy them, and $2.2 billion for support for 20 years. Given that we'll keep them for 30 years, it's $3.3 billion, so that's two and a half times or something like that. But it can be that much.
And typically--unbeknownst to most people--the newer equipment costs more than the old equipment because the new equipment is all technology-driven. It's all software. All you're buying, really, is a big piece of complicated software, which always gets updated and requires updating. So it's more expensive to replace new stuff than to maintain old stuff.
