The Su-37 'Berkut' was a one-off Sukhoi demonstrator combining the Flanker family's canards with thrust-vectoring engines, built to showcase extreme supermanoeuvrability.

The canards ahead of the wing, twin canted fins and its signature tail-slide and Cobra manoeuvres at airshows made it instantly recognisable in its short flying career.

History

Converted from a Su-27M airframe and first flown in 1996, it wowed airshow crowds with manoeuvres impossible for conventional fighters, using vectoring nozzles on its two turbofans to hold controlled flight at extreme angles of attack.

Variants

It remained a single technology demonstrator; its thrust-vectoring and canard lessons fed into later production Su-30MKI and Su-35 variants rather than into a Su-37 production run.

Where you'll see it

It never entered operational service and was lost in a non-fatal crash in 2002 that ended the programme, but its flight-control innovations live on in later Flanker derivatives.
