Aegis BMD missile
 Depending on the intercept point, Ballistic Missile Defense Systems can be categorized into three types; 1)Boost Phase Kill system, 2)Mid-course Phase Kill System and 3)Terminal Phase Kill System. Each system is optimized for each intercept scenario.
 Japan-US Joint Co-operative Research Program (JCR) for Aegis BMD System is concerned with Sea-based Mid-course Phase Kill System. Exploiting the effective result, Japan and US have commenced the co-operative development of the advanced Standard Missile-3 for Aegis BMD System.
