Does the RCAF have to fly over 2000nm of cold ocean without any hope of possible rescue or land? NO. At least in the Canadian far north if an aircraft has to put down it can do any emergency crash landing on land. Between the NZ and Antarctica there is no land apart from very few small remote islands and I mean small and remote. If an aircraft ditches in the water in the Great Southern Ocean the chances of surviving until rescue are really nil. So there is no comparison.When one looks at the KHI website the relationship exists with both Boeing And Embraer. I understand the need for a wider relationship and would assume that the Japanese understand the benefits that a support partnership with the likes of Boeing would offer. Given the very strong ties that exist between US companies and KHI I believe that that alone makes a C2 purchase more viable than a purchase from Airbus.
A look at allied experience with Euro military equipment shows a trend that should not be overlooked. The Tiger in Australia. ERYX and ADATS missile systems along with Iveco trucks here in Canada. How many countries used Transalls or Atlantics? Time and again American systems have offered longevity due to support from the US military establishment. Although I am a fan of many Euro systems such as C295W, Canadian engines, an A400 purchase by NZ would not provide the cost value that I believe would come from a C2 or KC390 purchase.
Similar to Canada's recent concern for its arctic area I am skeptical of the need to justify capabilities of military aircraft with a view to Antarctica support. Going back to Gibbo's comments regarding the essential capabilities of the next transport aircraft the 50% increase in payload that the KC390 offers over the existing legacy Hercules would be a huge capability increase on a one for one basis.
Regarding the KC390 that discussion has been done to death and no point carrying it on.With respect to the potential for more than four B200 replacements I also hope that more are acquired to allow greater capacity. Time will tell.
The ACTC RFT has not stipulated Kingair numbers or type. All it states is that any variant from the B200 - B350 is acceptable and that numbers required are to be determined by the respondents in their responses. The respondents have been advised of annual budget figure to work too, so they are able to structure their response within that.
