Results of the so called "DERA-study" which never existed. In real, BAe and DRA conducted simulated air battles against upgraded Su-27 Flankers (comparable to an Su-35 Super Flanker, early version). BAe went 1-vs-1 and 2-vs-2, DRA the more relevant stuff 3-vs-3 up to 8-vs-8. The results shown here are the results of BAe's mini-battles. Massed air battles by DRA shown a bit different, although comparable result.
