Would it be possible to have boxes of preloaded barrels? The technology to manufacture low-cost, lightweight composite barrels preloaded with long-range guided projectiles is feasible. These would be like vertical launch systems (VLS) and would give a precision weapon a range of about 50 nm.
The "boxes" the authors speak of are standard shipping containers. They anticipate them being placed on amphibious warship decks; and speak of moving them ashore when the ship leaves the area.
Which would make them one more system that could equip a modularized auxiliary cruiser that I described in "The AFRICOM Queen".
And I also spoke of the ship dispatching carried systems ashore for inland missions away from the littorals.
So obviously I endorse the concept. A fire support modularized auxiliary cruiser is totally okay by me.
