If we are just moving the exact same pallets/loads then why not just fly them direct in the C130? It is still a tactical lifter. If it's one (taller) pallet then build it 2 lower to start with (not sure how often we would need to crossload full pallets outside of a decent APOD anyway, again fly direct). As for vehicles, revert back to primary lifter if we really needed to, but really what is one pinzgauer good for?
Nice to be able to do exact same loads but is that what we really 'need' the smaller short-medium range lifter to do in this price, capability and employment range? Just like it's tier2 maritime counterpart do we actually require it to be creeping more into a quasi tier1 role or do we already have that covered off sufficiently? If we just need a basic niche filler then no point operationally or financially getting the same, albeit smaller fully tactical lifter if there is no actual requirement as again cost is key and funds are finite both now and over their life and will ultimately determine options, numbers and 'extras'(such as suites, self protection etc)
Again I guess it comes down to indviduals interpretations of tiers (for air transport) and what exactly is envisaged as to how both types should be utilised, operated, where, when etc as to which way we should lean. Pros and cons for both as always.
I take it you have not worked in a warehouse or cargo/shipping concern?
Again, I do not know what the standard sized shipping pallet the NZDF uses, or even if the ability to keep using the 463L pallet would be to NZ's advantage.
With that in mind though, if a service uses a standard sized shipping pallet for everything except the outsized loads and/or vehicles, it can significantly streamline cargo handling. Also keep in mind ahub and spoke arrangement for cargo handling and shipping.
There is a central hub, or perhaps hubs, were cargo comes in. It could be a theatre sea- or airport, a major airbase, whatever. If the incoming cargo is already packed on the proper pallet at the point on embarkation to the central hub, then all that needs to happen is for the hub to locate the correct pallet, and then load it aboard a tactical airlifter which will then transport it out to the FOB or wherever the next destination is, as an intra-theatre cargo move.
However, if the pallet or other shipping system used to move the cargo from the point of origin to the hub is different than the one used to handle the cargo being moved from the hub to the final destination, then the load needs to be broken down and repackaged, before it can be loaded aboard the tactical airlifter.
Another potential alternative would be to start from the point of origin using the pallets optimized for the final leg of the journey the cargo will be taking, but that can waste potentially valuable cargo space ( weight & volume) because instead of a shipping container or strategic airlifter being able to carry 1+ pallets depending on load, it might need to use 2 pallets, with different dimensions than the standard pallet to carry the same weight or volume of cargo.
In many respects the B757's illustrate this short of issue quite well. By cargo deck space/dimensions, one of the RNZAF B757's can do strategic airlift of 11 pallets of cargo. However, due to the low floor weight strength of the B757 baggage or cargo deck, each pallet can only weight IIRC 2,000 lbs. Being able to carry 11 of them does mean the B757 can airlift about 22,000 lbs of gear or cargo, but if the B757 is covering the point of origin to hub leg ofnthe cargo move, and then the cargo was to head to an intra-theatre FOB aboard a C-130, the load would either need to be repackaged at the hub (again, IIRC a C-130 has space for only 6 pallets) or then two separate C-130 flights would be needed.
As a rule when shipping something, the less the components of a load need to be handled once they have been packaged for shipment, the faster the load can be moved, and the less likely it is that some or all of the load will be lost or damaged in transit.
And depending on the load, the time in which it takes for the cargo to transit from the point of origin to the deployed end-user in the field can literally be the difference between life and death, or mission success or failure.
