How the OTO Melara 127/64 changes its ready ammunition

How does the OTO Melara 127/64's reload system work, and does it use a carousel?

It uses fully automated handling and can reverse the ammunition flow to change the ready-round mix; it can also reload at sea.

The OTO Melara 127/64's ammunition handling is described as fully automated. The mechanism can reverse the ammunition flow and remove rounds from the gun. That allows the ready ammunition mix to change instead of committing the system to the rounds already fed forward. Reloading at sea is another feature praised in the comparison, which also judges the American 5-inch/62 system favourably.
