Advantage of Aegis-radar option is land-based personnel can be deployed in shifts: Kanazawa Tech prof. Ito

Below is a comment from Toshiyuki Ito, Kanazawa Institute of Technology professor (security), on the three options on the table to replace Aegis Ashore.


The issue of the boosters, which led to the suspension of the Aegis Ashore deployment plan, is not an substantive one. Even if the system were deployed, it would have been difficult to intercept the latest Chinese and North Korean missiles.


The alternative options offer the advantage that the equipment already under contract would not be wasted. The land- and ship-based deployment option is good in that radar personnel on land may be deployed in shifts. It would be difficult for the Maritime Self-Defense Force to secure personnel for a response with Aegis vessels amid the personnel shortage. The artificial island option comes with the issue of how to protect the structure.


It is good that the Liberal Democratic Party proposal used the expression “capabilities to forestall ballistic missiles in enemy territory” instead of “capabilities to attack enemy bases.” There is no need to fixate on bases. Launching from movable launch pads or submarines is possible. The expression [capabilities to attack enemy bases] may be misunderstood by other countries as signifying preemptive attacks.
