  • Following the crash of a CV-22 Osprey on Nov. 29 near Kagoshima that cost the lives of 8 US servicemen, defense chiefs Austin and Kihara called the safety of the aircraft a top priority following a call on Dec. 12. The large search and rescue mission included 9 US and Japanese military commands and local civilians. A planned Japanese demonstration of the aircraft at Kyushu’s Saga Airport was canceled and all flights grounded. This was followed by the US grounding of its Ospreys until an investigation into mechanical issues was done. Biden called the servicemen the backbone of the nation, and Kishida expressed Japan’s gratitude to the airmen and said the country was filled with deep sorrow. Honoring their legacy, the allies pressed on with Yama Sakura 85, formerly a bilateral exercise that now includes Australian Defense Forces simulating the evacuation of civilians, information warfare, and countering combined arms.
