It's either cool Photoshop or .... Not sure why anyone would bother.
If it's for real then its not for increased manoeuvrability and presumably a larger bomb load is not the objective. I just hope the rudder and elevators are not independent , although if they were it might increase manoeuvrability....oooh it's a conundrum wrapped in an enigma.( and why is one aircraft shorter than the other???)
