@Halifax Tar, not discounting your experience, but even 4 people per ship, with 8-10 CPFs up and running is 32-40 people that don't actually exist in other trades. I think the full remar is still 7 or 8, so really up to 60-70 positions in the fleet. That's the equivalent of an entire AOPs crew.
So maybe not a big deal looking at a single ship, but at a fleet level this is a non-trivial demand on other trades that are already unable to fill billets.
The RCN wants to keep all the MCDVs, sail the Oriole and have multiple CPFs at HR, all while somehow getting new ships with additional billets. We just don't have the people, and all the NAVGENs in the world won't magically create trained sailors. We're running the ships dangerously short handed as it is, and the FRE fire on any non-HR ship would have likely gone far worse (possibly aground).
In that context the RCN makes Pollyanna look like a pessimist when it comes to HR solutions, and so far our COAs on the existing HR shortages are hope nothing happens, and it will all work itself out. Driving around 30 year old warships that don't meet commercial safety standards with minimum crews is just rolling the dice at this point, and the cumulative impacts of the thousands of technical defects, HR shortages, training deficiences, missing equipment etc is a bit terrifying if you look at it together (so we just don't do that).
