It's been bruited about that the eventual actual procurement cost for F-35 jet fighters, which are a seemingly important sort of 5th-generation jet fighter made by Lockheed Martin, has soared to an estimated US$156 million each, from the earliest projection of US$50.2 million each.

See the 3rd paragraph of http://en.wikipedia.org/wiki/F-35_Lightning_II
and

I guess Canada will beef up its mettle and buy those F-35 air fighters anyway, largely due to its escalating concerns over the northern territory.
