It was ugly, it had problems, and its 13th test flight ended in a crash. The engineers went back to the drawing board and redesigned almost everything.<\/p><p>The result was the Sukhoi Su-27 Flanker \u2014 a fighter so good that one design has spawned an entire dynasty of aircraft spanning five decades, a dozen countries, and over a thousand airframes.

When the Soviets learned about America&#8217;s new air superiority fighter in the early 1970s, they launched the PFI (Advanced Frontline Fighter) program to match it. The first prototype, the T-10-1, flew on May 20, 1977, piloted by Vladimir Ilyushin \u2014 son of the legendary aircraft designer Sergey Ilyushin.<\/p><p>The early design had serious issues. After the T-10-2 crashed on its 13th flight in July 1978, the team produced a heavily revised T-10S that was essentially a new aircraft. It first flew on April 20, 1981, and entered service in 1985. The final product was a revelation: <strong>Mach 2.35<\/strong>, a range of 3,530 km, a service ceiling of 60,695 feet, and a blended wing-body design that gave it extraordinary agility.<\/p>\n<div style=\"position:relative;padding-bottom:56.25%;height:0;margin:24px 0\"><iframe class=\"skip-lazy\" data-no-lazy=\"1\" loading=\"eager\" src=\"https:\/\/www.youtube-nocookie.com\/embed\/NlHdl2JAjfU\" style=\"position:absolute;top:0;left:0;width:100%;height:100%;border:none\" allowfullscreen><\/iframe><\/div>\n<h2 style=\"padding-top:22px\">The Cobra That Stunned the West<\/h2><p>At the 1989 Paris Air Show, Soviet test pilot Viktor Pugachev demonstrated a maneuver that Western engineers had considered aerodynamically impossible.
