They would want to see the external armaments fitted. Laser pointers to blind pilots and wave skimming protection guns etc. Look at the difference in design between Russki and Western designs, The quality of work is totally different and the reliability is much better than the Russki's.
Re the propulsion, The power pods are 360 deg operation and on ice breakers the ship can go in reverse to go through the ice pack, my Sons Company run such ships on oil and gas search and work in the ice. Some of the video I have seen is remarkable. The power pods can be exchanged quite easily in dry dock and they have no long prop shafts. Quoted today, 'It drives like a sports car'
