So, what do I feel like showing you today? How about the Sukhoi Su-35BM?
This is probably my favourite fighter aircraft on the planet, and ties for top spot with the B-1B for overall favourite. Like a lot of Russian projects, the Su-35BM has a long and tortuous development history, its roots (obviously) in the venerable Su-27 'Flanker' that was Russia's answer to the F-16 and F-15 in the Cold War race for air superiority in Europe. The -35BM, however, has been modified out of all relation to its predecessor. It has two direct 'parent' aircraft that are often confused with it; the base Su-35 and the Su-37. The former is in service in very limited numbers (c. 1 squadron - evidently the Russian Knights aerobatic team) with the Russian Air Force, and is effectively a highly updated Su-27. The Su-37 was a demonstration aircraft, of which only two models were built, and incorporated avionic upgrades from Western companies such as Thales. The -35BM differs from them both in that every nut, bolt and computer is entirely of Russian origin, and also modifies the airframe by cutting the canard foreplanes, resulting in ever-so-slightly decreased manoeuvrability (offset by the engines, discussed later) (this is incidentally virtually the only way to tell the three planes apart - though to confuse matters, canards can technically be fitted on the -35BM if the customer desires. It's not intended though), has a new powerplant, and is generally updated in virtually every area of the design as opposed to being a simple upgrade package.
Considered to be the most advanced non-fifth-generation fighter in the world, it's a big plane. This huge wing area gives it superb kinematic performance and control at virtually any angle of attack and speed. It can also carry a lot of fuel - significantly more fuel than any of its contemporaries, plus it has a probe-and-drogue system for in-flight refuelling and can be fitted with a kit to allow it do a buddy-buddy refuel (with one fighter in a flight acting as a mini-tanker for the rest of the group if need be). With 11 hardpoints and a 30mm cannon, it has excellent combat persistence and can carry virtually any weapon cranked out by the Russian MIC in the last twenty years. The -35BM is a multi-role fighter, but for once it actually outclasses most if not all of its contemporaries in all categories instead of being a 'jack of all trades, master of none'; its large size, power and lift allow it to carry a heavy weapon load for almost any imaginable role, with short-range missiles, anti-radiation missiles, medium and long-range radar or IR-homing weapons, rocket pods, TV, laser or IR-guided air-to ground munitions, dumb bombs, standoff weapons, air-launched cruise missiles and even huge anti-ship weapons such as the P-270 Moskit (SS-N-22 'Sunburn') or 3M54E/E1 Klub (SS-N-27 'Sizzler') cruise missiles fitting comfortably under its belly.
In terms of engines, it currently uses the NPO Saturn 117S powerplant, which is actually a derivative of the AL-31 family that have powered all Su-27 variants. It's the most powerful version of the engine to date, with the ability to supercruise and a much better service life and time between services than its predecessors. It also has three-dimensional thrust vectoring, which means the fighter can simply flip in any direction it likes at any point in flight. For an example, look at this video (I'm not actually sure whether the Su-37 - yes, I know it's a 37, but 35 is capable of all this - has 3D TVC enabled in this video, it may be only 2D. So you can imagine what 3D would be like!) Future production Su-35BMs will probably use the AL-41F1A, which is an AL-31 model up-rated to approximate the performance of the new AL-41Fs that will power the PAK FA (the first flight of which, scheduled for next year, I await with great interest).
Lastly, sensors and jamming. The current radar offered on the -35BM is the Irbis-E, which is fully mechanically mobile, giving it the ability to scan up to 120 degrees off-axis. To show how this compares, I direct you to this page by Air Power Australia. (If you want answers to debates, this is where you go, just set aside half an hour to read the page. I prefer to look at the nice simple graphs myself. The relevant ones are at the bottom.) It's claimed to be able to track an 0.01 square metre cross section target at 90km, and larger targets at up to four hundred kilometres. It has both air-search and ground-search modes, tracking 30 targets and engaging eight simultaneously in the sky, and four targets with two engaged simultaneously against objects on the ground. It also has an engagement radar in its tail; typically it will launch AAMs at the longest possible range, then do a quick about-turn and put its tail to the enemy, allowing it to engage enemies from long range even while keeping out of their missile range. Also useful for finding someone on your tail.
The -35BM also supports the latest in Russian jamming and electronic warfare pods; typically these will occupy the two wingtip stations, and provide far enhanced capabilities over current Russian hardware, bringing them, if not quite up to par with the most modern Western designs, certainly into the same category. The Su-35BM also incorporates composites and radar absorbent material which supposedly make it 'low-observable' but I don't seriously believe that they'd reduce the ability to track it by more than a few dozen kilometres at best. It's a big plane, and the turbine intakes would bounce radar waves straight back to the emitter no problem.
It's my solid belief that given equivalent levels of pilot skill, a Su-35BM will outbest any fighter in the world today save the F-22A Raptor. The latter's stealth gives it a clear advantage over any other aircraft ever built, and I don't imagine that unless the threat ratio was ridiculous, the Su-35BM would stand a chance. But any other opponent would be up for a hard fight indeed. One which, I think, they'd probably lose. It has a powerful radar, engines with an astonishing amount of thrust, fuel to burn, a superbly agile design, modern missiles, avionics and electronics, true multi-role capability and a feature set which sets it apart from all other 4/4.5th generation aircraft. Feel free to disagree, but there's no doubting it's an ultra-modern aircraft with a rich tradition and many successful designs behind it.
And it looks damn cool.
