They pointed out that the fleet needs three ships to be effective in combat. One for deployment, another for training while the third undergo maintenance. Currently, there are no plans to build a third ship.
Toshiyuki Ito, a retired MSDF vice admiral, added that with only 10 F-35Bs aboard, the ships cannot provide effective air defense coverage for the fleet. He urged the ministry to consider building more warships that require fewer crew instead.
Retired Vice Adm. Yoji Koda’s view was that the Defense Ministry made the decision without making sufficient detailed combat simulations.
