Je reviens sur un post précédent au sujet d'un article publié en 2012 (reprise de données 2004 paraît-il)
L'article énonce une métrique d'interception BVR “probability of successful engagement”, dont le mécanisme est basée sur une simulation milieu année 90 d'engagement contre le SU-35, indiquant un kill ratio déduit excellent pour le Typhoon (4.6:1) et médiocre pour le Rafale (1:1).
Comme les résultats ne semblent pas refléter le ressentiment actuel,
- Savez-vous si cette métrique a fait débat à l'époque (5 Rafale pour 1 Typhoon, un grossier raccourci) ?
- Savez-vous si cette métrique a été mis a jour depuis ?
- Savez-vous si cette simulation est encore reconnue pour évaluer les chasseurs ?

The aircraft’s counter air performance is cited as its major strength, and it is frequently cited to be “82% as effective as an F-22”.
The magic 82% number is derived from a mid nineties DERA simulation against a postulated Su-35 threat. The number is based upon the rather unusual metric of “probability of successful engagement” in BVR combat, rating the F-22 at 91%, the Typhoon at 82%, the F-15F (single seat E) at 60%, the Rafale at 50% and the F-15C at 43%.
The probability of a successful engagement can be translated into the more commonly used metric of a kill ratio by making some reasonable statistical assumptions, and doing this yields about 10.0:1 for the F-22A, 4.6:1 for the Typhoon, 1.5:1 for the single seat F-15E, 1:1 for the Rafale and 0.75:1 for the F-15C. So in the most common terms used, the Typhoon is by the DERA simulation about half as combat effective as the F-22A, about three times as combat effective as the F-15F, about five times as effective as the Rafale and 6 times as effective as the F-15C. If we compare this with cited USAF claims rating the F-22A as 10-15 times as combat effective as the F-15C in BVR engagements, this means that the DERA study roughly agrees with USAF assessments of F-22A vs F-15C combat effectiveness. The detailed assumptions applied to this study have not been disclosed.
