Reg,
I'm a little confused, I've seen the suggestion a couple of times here in the RNZAF thread that when there is talk of the 'flotation' devices on the Kiwi NH-90's that 'only' three of the eight 90's are fitted, correct?
I maybe reading this wrong, but I'm getting the feeling that it is being suggested that those three 90's fitted with the flotation device is somehow 'permanent' and it's 'only' just on those three 90's and not the other five.
As I've always understood it here in Oz, the (eventual) 46 MRH-90's in the ADF inventory are all the same configuration and that the airframes for Army and Navy are shared from the same common pool (hence the reason for the identical paint job, the only difference is 'navy' painted on some and 'army' painted on the others).
And that the 'flotation' devices on the Navy birds are not a permanent fixture, as obviously if and when airframes are 'rotated' in and around the 'pool' then the flotation device can be removed from a nominal 'navy' airframe and then fitted to an 'army' airframe and then it can be used in Navy service. (As a side note, it will be interesting, eventually, when a full complement of Army MRH-90's get to operate off the LHD's if they in fact will be also fitted with the flotation device when serving at sea).
Anyway back to the Kiwi birds, not questioning what you are saying that three of the eight 90's in NZ service are currently fitted with flotation devices (maybe that's just how they were delivered?), but I'd be surprised if somehow that was 'permanent' and the other five airframes couldn't also be fitted if an when necessary, eg, during a heavy maintenance period, or if airframes have to be rotated or re tasked.
If you can clarify this for me, I'd appreciate it.
Cheers,
