Japan's Ministry of Defense (MoD) is considering the procurement of Tomahawk cruise missiles as part of its plan to bolster Japan Self-Defense Forces (JSDF) counterstrike capability.
The MoD indicated to Janes that a procurement of the Tomahawk is a possibility as it seeks to redefine the country's defence posture in the face of what is perceived in Tokyo as rapidly escalating regional threats.
Japan's Kyodo news agency, citing a Japanese government source, reported on 30 November that the MoD is considering the acquisition of “about 500” Tomahawk missiles from the United States government between 2023 and 2027.
A spokesperson for the MoD did not confirm these plans but said that decisions on the Tomahawk “are still under consideration”. The spokesperson added, “The MoD has not decided anything [in relation to] counterstrike capability.”
Should Japan proceed with a programme to procure the Tomahawk, it would be first user of the system outside the UK and the US. Navies in these countries use the weapon on a range of surface and subsurface combatants.
Janes Weapons: Naval describes the Tomahawk as a submarine- and surface-launched subsonic land-attack cruise missile with inertial navigation system (INS) guidance. The missile, produced by Raytheon, is capable of hitting moving targets with multimode and mid-course guidance.
The range of the Tomahawk, depending on versions of the missile, varies from 550 to 2,500 km. The most recent versions of the missile – designated Block IV – are integrated with a datalink to enable the switching of targets while in flight and are capable of loitering for “prolonged duration”, according to Janes Weapons: Naval.
