The upgraded design rises to about 4,800 tons standard and 6,200 tons fully loaded while retaining similar engine power. Its Mark 41 battery doubles to 32 cells, enough for 128 ESSM if every cell carries four missiles. Japan's Type 23 surface-to-air missile is a domestic option that appears unable to quad-pack, leaving at most 32 such missiles before cells are assigned to rocket-assisted torpedoes or other weapons. ESSM and CAMM show how quad-packing could provide greater defensive depth through a domestic development or an overseas purchase. Cooperation with Britain and Italy on a fighter project is suggested as one possible opening for CAMM cooperation, with no decision assumed. The Japanese fit is expected to retain Type 97 torpedoes and domestic anti-ship missiles; a five-inch gun is anticipated despite a preference for 76 mm. The Australian fit is expected to use ESSM and may add a RIM-116 Rolling Airframe Missile system. The design remains an adaptable lower-tier escort whose customer can trade domestic content against magazine capacity.
