قررت اليابان شراء مدمرتين إضافيتين من طراز DDG-51 المزودة بنظام الدفاع الجوي AEGIS لحماية سواحلها من أي هجوم صاروخي كوري شمالي . اليابان تخطط لزيادة عدد المدمرات الحاملة لنظام AEGIS لديها من 6 إلى 8 مدمرات
بحيث تكون هناك مدمرتين جاهزتين على الدوام لمنع أي خطر صاروخي ,, مدمرتين محملتين بصواريخ SM-3IIA قادرة على تغطية كامل الأراضي اليابانية لكن هذا الصاروخ المطور بالشراكة مع الولايات المتحدة سيتأخر دخوله للخدمة حتى عام 2018 وربما أكثر ,,
اليابان قلقة أيضا من النشاط الصيني في البحر الأصفر لذلك هي عازمة على تعزيز قوتها البحرية

Nov 6/13: 2 more? Japan’s Defense Ministry reportedly plans to add 2 more AEGIS BMD destroyers to its next National Defense Program Guidelines submission, which covers its goals for the next 10 years. It would be the 1st step in growing the country’s BMD fleet from 6 ships to 8.The new SM-3 Block IIA missile being co-developed with the USA would allow just 2 ships to cover Japan, but that won’t be ready until 2018 or later. Based on a conservative 1 deployed, 1 portside/ training, 1 maintenance ratio, 6 ships ensures 2 deployed vessels at all times. In reality, the amount of time in maintenance is smaller, but 8 ships provide more surge capacity coverage, act as insurance against accidents that may take a ship or 2 out of service, and allow the JMSDF to use its top-end ships for more territorial patrols. America’s long-running failure to prevent North Korea from going nuclear has become a grave concern, but not the only one. China is stepping up its activities in the Yellow Sea and beyond, especially around disputed territories.The default assumption is that the 2 new ships would be based on Japan’s larger and more modern Atago Class derivative, with BMD systems pre-installed. Depending on Japan’s desired timing and budget, however, Japan could order 2 more Kongo Class ships to save a bit of money. Or, they could look ahead to the USA’s incipient Arleigh Burke Flight III design and its AMDR dual-band SPY-1D / SPQ-9B radar system.
