The 'Puma Mk2' will be the only surviving version of the Puma in service with anybody with the six-wheel undercarriage.
Loads of six-wheel Pumas out there, in both military and civilian use. Do they all get axed when Puma 2 comes into service?
Not convinced new wheels lowers the C of G either, but I await enlightenment from those in the know; including from those who like to land on soft ground.
