Su-30 vs RAAF Alternatives
Many visitors will be asking the obvious question of how the Sukhois stack up against the F/A-18A HUG, the JSF panacea and recently proposed interim fighters such as the F/A-18E/F.
Against all three types the Su-30 derivatives, especially with later engine subtypes, will always have a significant kinematic advantage - there is no substitute for thrust in the kinematic performance game. There is another factor to consider here, which is the superlative 10 tonnes of internal drag free fuel the Sukhoi carries. When not operating at extended combat radii, the Sukhoi driver has more fuel to convert into energy, and that energy can nearly always be used to an advantage.
With mutually competitive WVR missiles and Helmet Mounted Sights/Displays for close-in combat, all three types will live or die in a close in engagement with an advanced Su-30MK variant by pilot ability and good or bad luck. The Sukhoi combines high alpha manoeuvre capabilities with excellent thrust/weight performance, and is apt to have an energy advantage entering and prosecuting a close in fight. A JSF driver opting to engage a thrust vectoring late model Su-30MK in a knife fight may not survive to speak of the experience, unless the Sukhoi driver is unable to exploit his advantage properly.
In close in air combat terms the JSF qualifies as 'double inferior' against the later model Sukhois, since the Sukhois have an advantage in both thrust/weight ratio and in wing loading (interested visitors refer R.L. Shaw's Fighter Combat), and with its canard and thrust vectoring capability will generally be able to gain a firing solution quicker. Because the JSF is designed within the kinematic performance class of the F/A-18 and F-16, it is right in the middle of the performance envelope of aircraft the Sukhoi was designed to kill.
