Undoubtedly a combination of available resources as well as numbers required to sustain a similar capability to what we had.
From recollection, the 10 C-27J fleet will be undertaking the tasking that 8 C-130H aircraft performed after the Bous were retired.
It does seem a strange figure given other RAAF airlift squadrons are 6 or 12 strong, but then we see Army buying 7 CH-47F Chinooks and RAAF bought 5 KC-30A, so the numbers in reality are all over the place and don't mean much.
I expect they buy the number of platforms that meets a minimum level of directed capability and fits within the allocated budget, though with some projects there's clearly scope or the flexibility to maximise the number of platforms or assets acquired.
An obvious example of this that sticks out is the advanced targetting pod capability acquired during the Hornet upgrade.
From recollection, choosing the Litening AT pod, allow us to acquire 41 targetting pods, whereas the Sniper XR pod, would have resulted in us only being able to acquire 32 pods or so (can't remember the exact figure, but it was quite a few less pods overall) and this was the major reason why we chose Litening AT for the HUG.
Both met our requirements, but Litening AT allowed us more capability overall within our budget.
I can recall as a lad being at the Squadron picnic, my Dad an IP in the 130 observing the Boo Boos landing, they had all the flaps down and were making assault style approaches, it would have been about 1966, before he went to Viet-Nam. Course I loved the Boo Boo, my Dad "not impressed". LOL
