I like the Blackhawk but I think the utility of a rear ramp would be a huge benefit for moving ultra-light vehicles, UGV's etc. as well as for SAR and ASW versions if you're going for commonality. The AW-101/CH-149 has the added benefit of already being in service with the RCAF.
I like your train of thought - it's logical and makes a lot of sense.
Getting something that has a rear ramp so it could possibly deploy the ultra light vehicles, UGV's, the on-boarding of patients during SAR type operations and of possible ASW use in terms of deploying stores.
Do any countries use the 'hook in an ASW role, or as a helicopter with a naval det?
Can 'hooks be navalized, really? (I imagine if ordered for that purpose, certain parts or systems could be made from different materials than standard?)
I've seen the Brits operate Apache's and Chinooks from flattops before, but I don't think it's ever been for an extended period not to mention a full deployment...
(if Black Hawks can also be manufactured as Sea Hawks, I imagine building a navalized Chinook is quite doable)
As much as Black Hawks would be a huge step up from the Griffon, I am inclined to wait on the future helicopter designs coming online down in the US.
If they do come to fruition, they'll be an entire capability generation ahead of current aircraft. If we did buy Black Hawks and more Chinooks, it wouldnt hurt us - but we'd also be criticized for expanding our fleet of yesterday's aircraft, and be trashed in the press even more about not having the capability to contribute to doorkicking operations.
(Now there's a golden opportunity from an industry perspective! Canada should take the initiative and try to work out a deal to manufacture parts for, or entire aircraft, when it comes to the V-280. Demand will be high for a long long time, and waiting times may encourage potential customers to seek out whatever China's knockoff version will be...we could help limit that waittime. Set it up similar to having Strykers & LAV's built in London)
