TOKYO — Japan’s Defense Ministry announced Tuesday it has signed contracts worth nearly $2.8 billion with the country’s top defense contractor, Mitsubishi Heavy Industries, to develop and mass produce long-range missiles for deployment as early as 2026 amid growing fears of China’s increasing military strength.
The ministry said the contracts include enhanced versions of Mitsubishi’s Type 12 missiles for surface, sea and air launches, and a hypersonic ballistic missile for the defense of remote islands.
Mass production of Type 12 land-to-ship guided missiles and hypersonic gliding missiles, which have already been developed, will begin this year, the ministry said. Officials refused to provide the number of missiles that Japan plans to deploy but indicated that production is expected to gradually increase over the next five years.
Due to limited land space at home, Japan plans to hold pre-deployment missile tests at military bases in the United States, ministry officials said.
Another contract is for development of submarine-launched long-range anti-ship guided missiles, beginning this year and planned through 2027. Timing for their deployment is still undecided.
The development plan is based on a new National Security Strategy that Japan announced in December as it seeks to significantly increase its military power to deter potential threats from China, North Korea and Russia.
The new strategy includes developing a preemptive strike capability, a sharp break from Japan’s postwar commitment to limit its military to self-defense.
Japan has been strengthening defense in its southwest and recently placed missile units on remote islands as deterrence in case of an emergency involving Taiwan. But residents of Okinawa are divided over the move because of fears of becoming embroiled in a conflict.
Prime Minister Fumio Kishida said Japan is also buying 400 U.S.-made long-range Tomahawk cruise missiles capable of hitting targets up to 1,000 miles away for deployment beginning in 2026.
The Tomahawks are a stop gap while Mitsubishi works on upgrading and extending the range of its missiles.
Japan plans to nearly double its military spending over the next five years to $315 billion.
