Nurse, I do agree very much that the NH90 is a Puma replacement.
Roughly speaking the aircraft itself is merely designed by Eurocopter and the display system would be recognised by any Puma Mk 2 pilot ( the second prototype even has the Puma Mk 2 IFDS installed).
Further than that it has approximately the same weight and the same capabilities. Because of the FBW system its handling qualities are however better than the Puma...
