I have no right to post here but I thought I might timidly point to this:
Atlas Oryx - Wikipedia, the free encyclopedia
The Oryx is apparently a remanufactured Aérospatiale SA 330 Puma. Good things have been said about them. I'll quote one bit:
"South Africa chose the IAR airframe over existing airframes due to the Romanians use of carbon-composite materials which are lighter, stronger and also include sponson fuel tanks which give an extended range."
I'm just mentioning this because it seems that the Romanians do probably have unique experience and skills and it might not make sense to build uk capability in upgrading an outmoded system that is on it's last upgrade. This is just my uninformed impression.
