Could expeditionary sea bases carry folding cranes to reload destroyer VLS cells?
Short answerPotentially, but the equipment would displace other missions and make a highly valuable support ship still more important and vulnerable.
NotesFold-away cranes on an expeditionary sea base could in principle help replenish destroyer VLS cells. The engineering idea is plausible, yet the ship cannot take on the mission for free. Equipment, deck area, training, and operating time would be diverted from the sea base's primary expeditionary tasks precisely when those tasks are most needed. Concentrating another vital function on the ESB would also make an already important support ship an even more valuable target.
