The U.S. government said Tuesday that it has approved support for upgrading the Maritime Self-Defense Force¡¯s Aegis destroyers and notified Congress of the decision.

The estimated total cost for the Japanese government is $100.2 million.

According to a statement, the Japanese government asked for Aegis computer software updates, systems integration and testing, on-site engineering support and post-upgrade combat system trials.

The assistance ¡°will support the foreign policy goals and national security objectives of the United States by improving the security of a major ally that is a force for political stability and economic progress in the Indo-Pacific,¡± the U.S. government said.
