US Air Force To Accelerate CV-22 Osprey Deployment To Japan Written 5 April 2018

ExecutiveGov reports that the US Air Force will deploy five CV-22 Osprey tiltrotor aircraft to Yokota Air Base in Japan “earlier than previously anticipated” as part of the service’s “efforts to help address regional security concerns within the Pacific Command’s area of responsibility and comply with the 2018 National Defense Strategy.” The Air Force originally planned to deploy the aircraft to Yokota in 2020. The Ospreys will support training and disaster response efforts in the region, and the Air Force “plans to send more training support personnel there and an additional five aircraft as part of a phased-basing effort.”
