On Dec. 12, 2005 the Government of Singapore awarded Boeing a contract to produce 12 F-15SG aircraft for the country's next generation replacement fighter jet, and an option for eight additional aircraft at a future date. The F-15G is an advanced version of the U.S. Air Force's F-15E Strike Eagle. Two F-15Es are shown here performing Singapore flight evaluations at Elmendorf, Alaska in 2002.
