(pour ceux qui me connaissent, je suis Weo)

Voici un comparatif très intéressant sur les avions de combat actuellement en service ou en développement, très détaillé et pertinent :

Je ne poste que les conclusions :
‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾
Dassault Rafale

Rafale is also comparably expensive to buy and operate, but less so than Typhoon. It is also easier to maintain than any Western twin-engined fighters. It can provide adequate number of training sorties. As with Typhoon, however, it is expensive, and does not have very good road basing capability.

It has excellent situational awareness, including completely passive missile warning system and good cruise speed of Mach 1,4. However, its two M88-2 engines consume 7.762,56 kg per hour at maximum dry thrust, consuming half of Rafale’s internal fuel load within 18,24 minutes of supersonic cruise, allowing it to cover 464,4 km.

In dogfight, it has excellent transient performance thanks to its close coupled canard configuration. Its instantaneous turn rate is excellent, and it has very good sustained turn rate and acceleration. Its missile and gun armament is well suited for both visual range and beyond visual range combat, and gun in particular has comparably heavy firepower.

Saab Gripen

Saab Gripen is the cheapest of Western fighters in both acquisition and operating costs. While it has very small visual and IR signatures, its situational awareness is lacking due to the inadeqate rearward visibility and lack of IRST. It also has comparably slow cruise speed of Mach 1,05. Its RM-12 engine consumes 6.929,24 kg/h at maximum dry thrust, thus consuming half of Gripen’s fuel load within 10,39 minutes and allowing it to cover 188,9 km. It also has road basing capability.

In dogfight, it has good transient performance due to its close-coupled canard configuration. It also has excellent instantaneous turn rate, albeit sustained turn rate and acceleration are markedly inferior to other two Eurocanards. As with Typhoon and Rafale, its missile and gun armament is well suited for both visual range and beyond visual range combat, though it is limited in latter by lack of IRST.

F-22

Just as Gripen is the cheapest, F-22 is the most expensive of Western fighters. It has very large visual and IR signatures, and lacking situational awareness due to inadequate rearward visibility and lack of IRST. This is somewhat compensated for by its high cruise speed of Mach 1,72. However, its two F119 engines consume 17.055,2 kg/h at maximum dry thrust, thus consuming half of the F-22s fuel load within 14,42 minutes and allowing it to cover 451,06 km.

In dogfight it has very good acceleration and pitch onset rates, but roll onset and instantaneous turn rates are not as good as those of Rafale and Gripen. Its sustained rate should also be good. Its armament is unsuitable for both dogfight or BVR engagement, though a limited number of hardpoints present on wings might mitigate the dogfight performance problems somewhat.

Su-35

Su-35 is comparably expensive to buy and operate, limiting its force presence and ability to provide adequate number of training sorties. Latter is actually impossible to achieve due to high maintenance downtime. It does have good on-ground survivability.

Large visual and IR signatures harm its ability to surprise the enemy, while its own ability to detect surprise bounces is limited due to inadequate rearward visibility.

While it may be capable of achieving adequate transient performance, it can only do so at high cost in energy. This problem is somewhat mitigated by adequate acceleration and high fuel fraction. Armament is adequate for both visual range and beyond visual range combat.

Eurofighter Typhoon

While Typhoon is cimparably expensive to operate, it is still less so than many other modern fighters. It is also easier to maintain than most twin engined fighters, except for Rafale, and can provide adequate number of training sorties. However, its high unit price means that it is lacking when it comes to providing aerial presence, and it has less than ideal road basing capability.

While it has adequate passive sensors suite and cockpit visibility, active missile warning system might alert the opponent on short range (assuming that enemy’s RWR is capable of detecting very short wavelengths used by the MAWS). It does have adequate cruise speed of Mach 1,5, but its two EJ200 engines consume 9.054,64 kg per hour at maximum dry thrust. This means that it consumes half of its internal fuel load within 16,4 minutes of supersonic cruise, allowing it to cover 417,6 km. Cruising at lower supersonic speed can extend endurance, but it will reduce distance covered.

In dogfight, it is handicapped by its comparably large size and inferior transient performance, particularly sluggish roll response. It does have very good instantaneous and sustained turn rates and acceleration, but it is still primarly a (bomber) interceptor while Gripen and Rafale are dogfighters. Its missile and gun armament is well suited for both visual range and beyond visual range combat.

Large visual and IR signatures harm its ability to surprise the enemy, while its own ability to detect surprise bounces is limited due to inadequate rearward visibility.

F-35

F-35 is very easy to detect visually or with IRST, as it is large, has massive IR signature and is incapable of supercruise. Unlike F-22, it does have IRST, but its rearward visibility is even worse, and IRST itself is optimized for detection of ground targets. Its cruise speed of Mach 0,95 is slower than any other modern Western fighter. Fuel consumption of 11.252,2 kg of fuel at dry thrust allow it to maintain that speed for 22,08 minutes while spending half of its internal fuel. This allows it to cover 381 km.

In dogfight, it has sluggish acceleration, likely average pitch and roll onset rates, and inadequate instantaneous and sustained turn rates. Its armament is unsuitable for both dogfight or BVR engagement.
