The F-22's bottom-line effect?

Lockheed Martin's fourth quarter financial statement out this morning carries a nice surprise for Wall Street. Since Lockheed's last financial update in October, the defense contractor has raised its minimum sales target for 2008 by about $550 million. Lockheed's press release explains the increase is "primarily as a result of volume and performance in the Aeronautics business area".

Hmm, let me think. What's happened since October that would boost sales for Lockheed's Aero sector by half a billion?

Could it be this?
