Exhibit: Sabre Ace
You start the Soviet Campaign in the Yak-9 (Yaklovev-9) which was a competent ground attack and air superiority fighter of 1940's vintage.
If you survive the first 10 missions, you will be upgraded to the MiG-15.
The MiG-15 was designed just after World War and the powerplant was based, ironically, on a Rolls Royce Design given to the Soviets by the British Government!
Allied pilots were dismayed to meet this aircraft in huge numbers over Korea. It outclimbed anything in the Allied inventory at the time.
