Reality:
We are stuck with Griffon in its current configuration, with a few minor tweaks, for the foreseeable future. It will be replaced outright, eventually, but not for another decade or three. Or more. No Griffon is ever going to be "upgraded" to a UH-1Y. That is a completely new helicopter. Yes, one could stick old CH146 builder's plates on the new machine and call it a CH146B "upgrade" for political reasons, but that is not very honest.
We already have, from the government perspective, a new toy helicopter, and that should be enough to make us happy. Santa won't be back for a long time.
Chinook, despite careful and thorough planning, still lags. Introduction of a new fleet is more of a challenge than most people realize. Way more of a challenge. A radically different fleet - we have no history of attack helicopters whatsoever, beyond a few exchange Officers - brings even bigger challenges, and not just within the Tac Hel community.
We do not have anywhere nearly enough people to adopt a third fleet into the Tac Hel community. We are as-close-to-never-as-one-can-possibly-get going to have enough people. That is the same situation that every other community in the whole CF (save, perhaps, ever-more-numerous and ever-more-bloated HQs). CF total strength is capped. To increase positions in one place means reducing positions in others. To gain something, we must give up something else. What should that be?
People take years to recruit and train (much, much too long - and that is a whole other rantable subject), and even longer to develop operational experience. We cannot knit or buy Pilots and Techs. We do not have enough as it is, and experience levels are already low across the community. There are huge delays between courses, and three or four years wasted in university or RMC in the case of Officers. We cannot retain enough of the people in whom we have invested so much for a variety of reasons, many of which are correctable if the right people in the right places cared enough and truly wanted to.
The government cannot even buy simple trucks as it is, or decent boots, or maintain sufficient quantities of basic operational clothing. It cannot buy ships, maritime helicopters, fighters, or a host of other items, "cheap" or otherwise, in a timely fashion.
There are so many other priorities, and always will be.
And it is far easier to not get something that one has never had than it is to give up something that one views as absolutely essential in order to pay for it.
