Can composites reduce topweight in a warship?

Could composite materials reduce the height and weight of equipment high in a warship?

Possibly, but the structure still has to be strong and stable enough for its sensors; reducing topweight cannot compromise the ship's ability to support the equipment safely.

Lighter materials are worth investigating, but a high-mounted mast or radar structure cannot be judged by mass alone. It must remain strong enough for sea loads and for the equipment it carries, so material substitution cannot be separated from structural design. An Australian mast that grew out of proportion to its ship shows how requirements can accumulate without adequate whole-ship review. A heavy structure high in the ship worsens stability, while even small movement at the radar can translate into a large error at the distant target.
