The issue I would have with the Dutch-style JSS is a smallish fuel capacity. In Dutch service (as tankers) they are really just to act as a support vessel to a couple of deployed frigates, and not fleet tankers. It would mean that a RAN JSS would have difficulty acting as a tanker for a task force or persist for high endurance missions. It may suit the needs of the Dutch, but I would have thought it is a bit weak as a tanker given the riches of amphibious lift the RAN will soon have. I think this is an excellent example of two dedicated vessels being better than combining the roles.
IMO, in addition to a greater stores capacity over the Success, you would hope its replacement should have at least two helicopters. Space for one or two more would be better, even if it (they?) only carry two.
As for the images attached to my previous post, it is from the RAN's 75th Anniversary in 1986.
In case anyone is wondering, looking at my larger files the colour image contains:
Back to front: USS Missouri (BB-63),
HMAS Adelaide (FFG-01) and a RN Type 42 destroyer (from the longer bow, I assume a Batch 3),
HMCS Qu'Appelle (DDE-254) and two of her Mackenzie-class sisters, and (from the darker RAN gray) either Swan or Torrens on the inside,
HMNZS Canterbury (F-421) , I assume HMNZS Southland (F-104) but cannot be certain, and HMAS Parramatta (DE-46).
On the b&w photo taken just a few minutes later, front to rear:
Three rows as above,
Two OHP-class FFGs (Aust or US?),
Two Spruance-class DDGs,
USS Missouri (BB-63) again (oddly, there isn't anything tied up further down)
Left of the finger wharf an Invincible-class carrier,
Right of the finger wharf a Blue Ridge-class command ship,
To the right of the LCC there is a gray splodge with a black painted mast that looks vaguely like a CFA-class DDG, and in front of the LCC there is something tied up that could either be another DDG or indeed anything at all painted gray with a black top.
