By GlobalDataThis sale is expected to bolster Japan’s defensive capabilities, aligning with US foreign policy and national security objectives by strengthening an ally in the Indo-Pacific region.
It aims to enhance the Japan Maritime Self Defense Force’s (JMSDF) ability to combat current and future threats using its Aegis Weapon System-equipped vessels, contributing to regional integrated air missile defence.
The acquisition is not anticipated to disrupt the existing military balance in the region.
This development follows a recent contract awarded to Raytheon, a business of RTX, by the US Navy to produce SM-6 Block IA missiles, with production expected to be completed across several Raytheon facilities by 2027.
In response to security challenges from China and North Korea, Japan has been channelling resources into the advancement of its military capabilities.
This includes the creation of advanced stealth fighter aircraft, the introduction of missiles with extended reach, and the construction of smaller, more agile naval vessels.
For the fiscal year 2024, Japan has allocated a defence budget totalling $72.3bn. Projections indicate that from 2025 to 2029, the annual compound growth rate for this budget will exceed 4%, according to GlobalData.
