The Su-47 "Berkut" on take off.  Though the picture is a little grainy, note the control deflections (canards, slats/flaps, rudders and stabilators.  More info from the Wikipedia site here:

A good comparison of relative sizes between the Su-27UB and the Su-47.  To compare with American fighters, they are about the same size/weight as the Grumman F-14.  Find out more here:

The Sukhoi fighter has had several designations over the twelve years since it's flown.  The Su-47 seems to be the current official designation, the "Berkut" translates as "Golden Eagle."  More information here:

As a Sukhoi fan, I would be remiss if I failed to lust after the Berkut.  The Su-47 is a "fifth generation" fighter that combines extreme maneuverability and thrust-to-weight better than 1:1.  While a large aircraft it still boasts some outstanding performance (top speeds quoted between Mach 1.6 - 2.3, depending on the source).  The Berkut has captivating lines with its futuristic canard/forward swept wing configuration.  I use a small metal model of this brute (mounted on a stick) during my pre- and post-flight briefings, and I never tire of looking at it twisting and turning through the class room.
