Changing warheads in a vertical launch system

Can crews change a missile warhead inside a modern VLS, and do its canisters create extra constraints?

The round must be handled from the top as a canistered unit, and the canister design can create system-specific problems.

Modern vertical launch missiles are handled as canistered units. Changing a warhead or round requires access from the top rather than work on an assembled weapon inside the cell. Canister design can introduce its own problems, as the discussion of the Slava-class installation suggests. The loading arrangement therefore shapes how crews replace and maintain the missile.
