Su-34

I've allways know as Su-34, but in the web of Sukhoi, they call it Su-32.

Aviation press, military and Sukhoi company designations vary. Sukhoi initially designated Su-27UB side-by-side strike variant Su-27KUB and in 1995 redesignated Su-32FN as these designations promoted its maritime role on the international market which Sukhoi felt it will receive most sales. In 1999 they redesignated again Su-32MF to stress its multirole capability since the international market changed its climate.

 

The Russian military press has always called it Su-27IB or fighter-bomber and occasionally Su-34 since the beginning, the Su-34 designation may have been given within the military because some cockpit features are from the Su-24 including the seats but that's my speculation.

Presently the Russian air force designation is Su-34.
