The aforementioned slide is of the German proposal, based on the F-125, for the future Australian frigate contract; it has space for 48 VLS cells as per the manufacturer. Some Websites say it can have 64.
Thank you. It’s a shame we don’t acquire these for our marine expeditionary units since we are building so few Zumwalts.
