That is what it looks like. It is the first time I have heard of it the RAAF using it. Perhaps it is on loan from the USN.
Reading between the lines it could be the RAAF evaluating that concept and by extension perhaps looking at the USNs other buddy refuelling option ... the Stingray.
There was some scuttlebutt back in the day, that RAAF acquired the refuelling pods as part of the $6.6b package, but I’ve never seen a single photo or any announcement that I can recall, confirming that…
We seem to be trialling lots of things at the moment, because obviously other service experience isn’t relevant…
Refuelling pods on Shornets. (USN have done it for years).
Litening pods on a C-130 (USAF and USMc have done it for years).
C-130’s in the special operations role (USAF and others have done it for years)…
I suppose this is evidence gathering for future capability acquisition business cases, but it does seem like we rather enjoy attempting to reinvent the wheel…
