The powerful Suchoi Su-27 and its two-seat more advanced development, the indian Su-30 MKI, are for many aviation enthusiasts the epitome of a highly agile fighter aicraft.
Due to an invitation of the Indian Air Force (IAF) Lt. Col. Frank Simon of the German Air Force´s Fighter Wing 73 (Jagdgeschwader - JG 73 « Steinhoff ») had got a chance to get an idea how good the flight performance of this Flanker-C (NATO-Code) in comparison with the newest modern Eurofighter/Typhoon.

in front of an Indian Suchoi Su-30 MKI
Simon is the right man for such a task. He flew already the Mig-29 in the Air Force of the NVA (Nationale Volksarmee of ex East German)and now for the Fighter Wing 73 « Steinhoff » (JG 73 S). He is a very experienced pilot and is therefore completely qualified to fly the most modern Eurofighter of the German Air Force.
The powerful Suchoi Su-30 MKI (Multirole Export India) is a two-seat advanced variant of the Russian interceptor Suchoi Su-27 Flanker, which is equipped with the latest avionics, what come from different nations (Russia, Israel, France and India). It was produced in cooperation with the Indian aviation industry. Its thrust vector control allows the Suchoi being able to fly special maneuvers beyond the purely aerodynamic possibilities, the so-called post-stall area. The unimaginable Pugachev´s Cobra maneuvers have thoroughly impressed the audience on most major international air shows.
« In this respect, this flight with Su-30 MKI of IAF was a special for me and I was looking forward with great anticipation to this event », said Frank Simon, who was accompanied on the trip to India by Lt. Col. Frank Neurath of the German Air Force Test Center Manching (WTD-61).
When wearing the flying suit, Simon had got his first Déjà-Vue:
"The Indian Flanker pilots use the same Russian anti-G trousers that we had on the Mig-29. ".
Frank Simon got then the preparation briefing for the flight as a backseater from his Indian Suchoi-Pilot such as :
How to operate the ejection seat in emergency falls; a short presentation of the Flanker, the cockpit and the planned flight maneuvers and procedures.

« In the air space for dogfight training with the breathtaking scenery of the Himalayas, my Indian pilot demonstrated to me how close and hard the Su-30 can fly and lets me then try for myself. We flew a variety of maneuvers with and without thrust vectoring, Immelmann, looping, and finally the famous cobra maneuver, too.».
And although the jets were still below the Himalayan peaks, the air was probably quite thin for the engines of the Suchoi, because the Indian pilot wanted « the cobra » only with the nose slanted downward and not upward. He maybe fear that the incoming air insufficient to carry the aircraft during the combustion of mixture of fuel and air.
« In the end we still practice how to fly the Flanker by using of the thrust vector control to out-maneuver and be able to shoot down a bandit, who attacked you from six. For this maneuver, you pull the aircraft sharply upward after a hard curve – it looks like a cobra.
At this steep attitude you get into a low speed range,in which the thrust vector control should be automatically activated to take countermeasures. So we now turn the thrust vector control - and the elegant nose of the Suchoi drops down to aim straight to the maybe-stunned opponent :
quick aiming with the helmet visor, and then firing an infrared air-to-air-missile on the opposite fighter - and that´s it. ». So much for theory.
Eurofighter would have an easy game !

« Then I ask the pilot, he should do this maneuver again and quickly put the nose back over the horizon in order to follow the enemy, if our opponent could recognize our intention and tries to climb over us for countermeasure. But that's what he failed to do it. The nose of the Flanker - despite thrust vector control – is too heavy for the planned maneuvers ! An Eurofighter should have then an easy time, because the Flanker is now sluggish in the air without speed !
We have tried the same maneuver once again at the end of the flight – with the same result. ».
In this case the result was not so amazing :
When the Suchoi has completed successfully the cobra maneuver and the opposite pilot should have not recognize in time this maneuver, then the Flanker was probably the winner of this fictional dogfight.
However, the Cobra maneuver – not depending on the type of the fighter or on the experiences of the pilot – can be quite guessed in advance by opposite experienced fighter pilots. The rest is done by the inertia of the mass : a heavy combat aircraft like the Flanker is disadvantaged by its high mass, when it flies a maneuver only based on its exceptional aerodynamics and by using of powerful engines with thrust vector control, which is normally impossible for the most other fighters.
Alone the fuel load of the Suchoi is over 9 tons, almost reaches the mass of an Eurofighter itself !
Flanker-C is clearly a heavy weight fighter, a Goliath : and even with its powerful engines it cannot overcome the limit of natural physical laws !
Strong opponent
Because the Flanker was originally designed as a heavy interceptor and went already into the army service, they cannot compete to the much smaller and lighter Eurofighter in the fictional, above described dogfight. Together with a better thrust to weight ratio, Eurofighter could be the winner of this fictional dogfight exercise over the Himalayas…
However, one must take into account when comparing all weapon systems that the presentation of such maneuvers is only a part of the whole picture. In reality, the dogfight would take place mostly in a BVR (Beyond Visual Range)-combat between two pilots who try to shoot down his opponent at distances outside the range of human eye.
And of course, the Suchoi Su-30 MKI – within or without the Cobra maneuver – is always a very agile fighter, which should not be underestimated. Experienced Indian pilots can now concentrate on flying new exceptional flying maneuvers with the thrust vector control.
Such exchanging projects of both Air Forces (IAF and GAF) are always benefit for all involved parties.
