The F15 Strike Eagles: Robust, Swift, Versatile with a Big factor of Menace. To me, it is considered the main air superiority fighter of the US Airforce for more than a decade now. And still it proves to be a lethal fighter even today. Though it is showing age, the F15 is still the main fighter of the US and has been exported to many countries now. Of which the most recent agreement to buy the F15s is Singapore, the variant being the F15T. The design of this fighter gives it a sturdy feel, on top of the fact that it will have many more adventures in the sky for years to come.
