Nick, with respect, the UH-1 is better for NZ than the Blackhawk at this point in time, and the NH-90 allows for more future expansion in roles than the Blackhawk (range, capacity, lifting power). That is why they looked at the Blackhawk and rejected it. I'm not surprised that 50% of the aircraft in Iraq are Blackhawks, thats because it is mostly Americans fighting there, and they have lots of Blackhawks.
So you're saying that a Hummer is ALWAYS better than a Mini Cooper?? Bold statement, and quite plainly wrong. Hence, for NZ the UH-1 is better suited than the Blackhawk. As a former Sikorsky bod, you should know that understanding your customers requirements is critical to a successful outcome.
True though, I do know little about combat helos. I was only a mechanic and door gunner on them for a few years. Woe is me.
RFP's were asked for. Bids were placed and evaluated (over a looooooonnnnnnngggggg period of time). The copter that best met the requirements of the RNZAF won.
