This article from The Warzone provides some depth on containerised missiles
Lockheed Martin is offering containerized launchers to Australia as it pushes to acquire sorely needed longer-range air and missile defenses.

I can't see the Typhon system, or its Navalised Mk70 equivalent being fitted to the Hobarts, Hunters, or even the LHDs. The footprint is massive and you give up helo/AUV capability (fully for the Hobarts and Hunters, at least partially for the LHDs). Given we rely heavily on helo ops for submarine defence, I can't see that trade off working.
Perhaps for the eventual LOCSVs, but then I think adaptable deck launchers are simpler.
The Typhon resembles an elephant herd. To have anything like the number of missiles necessary for stand alone defence, you are talking in the order of 8-12 launchers (gives 32-48 missiles). Plus radars, generators, control rooms, spare missiles, cranes, fuel tankers, and hotel services for in the order of 100 crew, plus endless small vehicles. Moving this thing is a 30-40 truck event.
Given that Typhon is either unable or hugely inefficient at short-medium defence, then it also needs to come with a NASAMs battery. So there is another dozen vehicles.
It needs an LHD to move it around its so big, and has the covertness of rock band out of Mad Max (there is no covering this thing in a few fig leaves).
So, it perhaps has a use as a major base defence system. Say around FBW or Darwin, where with an SM6 loadout it can provide balistic missile protection. It becomes a semi stationary system. If you are going to do that, then an Aegis ashore setup is probably an equivalent money alternative.
The only thing going for Typhon in my view is that it can use the SM6, which is a missile we have chosen to hold (hopefully) significant inventory for, and could be used in the future for SM3.
