Information on sea-based surface-to-air missiles was leaked along with data on the Aegis defense system, jeopardizing the deployment of a key defense system, according to sources familiar with the probe by Kanagawa prefectural and Maritime Self-Defense Force police.
MSDF Aegis ships were scheduled to start receiving the state-of-the-art SM-3 interceptor weapons system developed by the United States this year.
The U.S. has lodged a stern protest with the MSDF over its lax management of intelligence.
