Ask which is better, the MiG-29<\/a> or the Su-30<\/a>, and you have already misunderstood the question. They were never meant to compete. They are the two halves of a single idea \u2014 the Soviet Union's deliberate decision to build one small fighter and one big one, each doing a job the other could not. It is one of the neatest examples in aviation of how a country's whole air-power strategy can be read from two aircraft.<\/em><\/p>\n\n

One requirement, split in two<\/h2>\n

In 1969 the Soviet General Staff issued a requirement for a PFI<\/strong> (Perspektivnyy Frontovoy Istrebitel<\/em>, roughly “advanced frontline fighter”) \u2014 a next-generation machine with long range, great agility, Mach 2+ speed and heavy armament, built partly in response to the American F-15<\/a>. The specification proved too demanding and too expensive to satisfy in a single airframe bought in the numbers the Soviets needed.<\/p>\n

So, around 1971, they split it. The heavy half \u2014 the TPFI<\/strong> \u2014 went to the Sukhoi<\/strong> design bureau and became the Su-27<\/a> Flanker family. The light half \u2014 the LPFI<\/strong> \u2014 went to Mikoyan<\/strong> and became the MiG-29 Fulcrum. The planned force was roughly one third heavy fighters, two thirds light. If that sounds familiar, it should: it is almost exactly the logic behind the US Air Force's own “hi-lo” mix of the expensive F-15 and the cheaper F-16<\/a> \u2014 the fly-off that also gave us the YF-17 Cobra<\/a>.<\/p>\n

The MiG-29: the light knife-fighter<\/h2>\n

The MiG-29, which first flew in 1977 and entered service in 1983, was designed as a nimble frontline fighter to work close to the battlefield. Powered by two Klimov RD-33<\/strong> engines, it is small, agile and famously good in a close-in dogfight, with a helmet-mounted sight and off-boresight missiles that gave early Western pilots a nasty surprise once they got to fly against captured examples. Its weaknesses were the flip side of its virtues: short range and a modest fuel load meant it was built to defend a patch of sky, not to roam.<\/p>\n

The Su-30: the long-range heavyweight<\/h2>\n

The Sukhoi took the opposite path. The Su-27 that emerged was a big, long-legged air-superiority fighter with the fuel and radar to control huge volumes of airspace. The Su-30<\/strong> is its two-seat, multirole development: twin Saturn AL-31F<\/strong> engines, enormous range, a heavy and varied weapons load, and \u2014 on versions such as the Su-30MKI \u2014 thrust-vectoring nozzles for the eye-watering airshow manoeuvres the Flanker family is famous for. Where the MiG-29 is a knife, the Su-30 is a broadsword that can also carry the whole armoury.<\/p>\n

Two answers, not one winner<\/h2>\n

That is why comparing them by a single scorecard misses the point. The MiG-29 was cheaper, lighter and made to be bought in bulk for frontline defence; the Su-30 is heavier, costlier and made to reach out and dominate. Together they were meant to cover the whole spectrum \u2014 exactly as the F-16 and F-15 do for the West.<\/p>\n

Of the two, it is the little Fulcrum that has become the one enthusiasts most dream of strapping into \u2014 and that dream is a real one. Flying the MiG-29 to the edge of space<\/a> remains one of the most extraordinary experiences in civil aviation.<\/p>\n\n\n\n
