Japan eyes upgrading all its Aegis destroyers with US Tomahawk missiles by 2027
- Plan is to develop capabilities to strike targets inside an adversary’s territory, amid North Korea’s nuclear, missile threats and China’s military rise
- The announcement follows the government’s intention to purchase 400 Tomahawks earmarked for this year at a cost of US$1.6 billion
The Japanese government plans to upgrade all eight of its Aegis destroyer ships by 2027 so that they can be installed with Tomahawk cruise missiles bought from the United States, a government source said on Saturday.
The move is intended to help Japan develop capabilities that can strike targets inside an adversary’s territory, amid North Korea’s growing nuclear and missile threats and China’s military rise.
According to the source, Japan plans to acquire the latest Tomahawk Block-5 missiles with a range of about 1,600 kilometres. The government has already announced a plan to purchase 400 Tomahawks, earmarking 211.3 billion yen (US$1.6 billion) in the 2023 budget starting in April.
Currently, two Maritime Self-Defence Force ships equipped with the Aegis missile defence system are stationed at the Yokosuka naval base in Kanagawa Prefecture. Two others are based at Maizuru base in Kyoto Prefecture and the remaining four at the Sasebo base in Nagasaki Prefecture.
The government plans to earmark funds to refurbish the vertical launching system of each ship from fiscal 2024 for the installation of Tomahawk missiles.
