Australian Navy's "Minor War Vessel Concentration Period (MWVCP)"

I believe that the US Navy would consider this a type of combined Amphibious - Littoral Ops type operation.  From the Royal Australian Navy website...

The Minor War Vessel Concentration Period (MWVCP) sea phase has commenced in waters off Darwin, with five Royal Australian Navy ships practising general mariner, surface and amphibious warfare skills.

Interesting.  Since they practice amphibious warfare I wonder if the Canberra Class LHD's will be allowed to participate once they come online.
