Guys.....
some may have been a little premature in assuming that a second [AFT] thruster
was missing
From the sectional image posted [thanks Umi].......we see the conventional FWD thruster being indicated as powered by an electric motor
However just AFT of this we see a representation of a diesel engine through a gearbox to a thruster.....but it appears to be inclined downwards
More than meets the eye I would suspect...as this appears to be an Azimuth rotational thruster
Sceptics the lot of you......nothing wrong with Fried Rice......
