Would an arm launcher help protect an icebreaker's missiles?

Could an arm launcher with missiles kept in a heated compartment suit an icebreaker better than VLS?

The idea has advantages, but the arm still needs protection and heating; a retracting launcher is suggested as a possibility.

The proposal stores missiles in a heated compartment and brings them up to an arm launcher only when needed. That could address some exposure problems, but the launcher itself still needs protection from ice. A folding or retracting arm is suggested as one possible arrangement. Heating and clearing ice remain necessary even if the missile spends most of its time below cover.
