Sukhois PAK-FA or T-50 is started taxi trials with an aim to make first flight early in January 2010. Zelin said that by 2009 will be ready three fifth-generation aircraft. All of them are currently undergoing tests and are more or less ready. The PAK-FA development is still classified, so images of the stealthy fighter are expected to appear only after the first flight. Delivery to VVS planned for 2015 as Russia’s basic front-line fighter.
