Sukhoi Design Bureau - The Legacy of Pavel Sukhoi
Of the big names in aviation in the 1930's and 1940's - Wright, Curtis, Mikoyan-Gurevich, Hawker, Focke-Wulf, Mitsubishi just to name a few - most are long since defunct, dismantled, or otherwise sold off to various buyers. Many have not, in any incarnation, produced a combat aircraft in decades. Their founders long dead, their factories destroyed, mothballed, or turned to other use, their names are known only to history.
There are, of course, exceptions. Saab of Sweden has been building fighters for decades - the Gripen fighter only their most recent entry. Dassault has been around for some time as well, and its Rafale is top notch. Lockheed produces the F-22, and still retains its name as part of the merger with Martin Marietta in 1995. And though it has been folded into a national Russian aviation group, Mikoyan Gurevich remains alive and well.
Then there is Sukhoi. Founded by Paval Sukhoi in the 1930's era Soviet Union, Sukhoi as a company is less well-known than Mikoyan Gurevich, Sukhoi fighter jets are renowned worldwide for their maneuverability and functionality.
