There was consideration given within the DND on alternatives, because this was a costly purchase and there were alternatives available. The requirements were basically set to be only heavy lift (CH-47) at Hillier's request. That killed any possibility of looking at alternative force structures.
Merlin is a AW-101 derivative, which we already operate in the Comorant. So it would have been easier to get technicians for that helicopter than for a type we didn't operate anymore. And the supplier relationship already exists. The other option was to go with the H-92, which was less capable of the two.
I completely agree that having those bells and whistles are useful, but when you're paying nearly double the basic model flyaway cost, there must be grounds to question the utility it provides at that cost.... especially when there is an alternative that can provide some or most of the capability required at a lower costs.
I don't have a hate on for Hillier in the least... Hiller did what he had to do in his situation. Absolutely he got critical equipment into the field in a timely manner and I commend him for that. He was also instrumental in improving the forces However that doesn't mean I have to love or agree with every one of his decisions. His get things done approach works well in some circumstances, but not others where careful analysis and consideration could have yielded better results.
Want an alternate scenario? Lets consider going with the Merlin. We get a helicopter with 50~60% of the capacity, but at about half of the upfront cost. So we're less capable in the field with smaller medium lift helicopters, but we double our operational fleet size and standardize around one common airframe with all the advantages that go with it. And they were seen as being significant.
Is that realistic? I don't know because the analysis was never fully considered. And that's what I'm interested in for case. Saying it must be a heavy lift helicopter of X type and no other basically locked us into a choice we're now paying for and will have to sustain on a potentially shrinking budget.
Why is considering this important? During the 1990s we saw our combat capability get gutted due to budget cutbacks, just like with the US Army right now. If we go through additional cutbacks, this capability will be a big target because of its high operational costs. I completely understand the operational need for it... and I agree the Chinook is a phenomenal capability. However if Canada goes through another round of defence cutbacks in the future, this will be one of the capabilities that will be considered. Had it been put on a more affordable basis its risk would be significantly less.
