After a shaky development history that included several deadly high-profile crashes, the Osprey became a symbol of the anti-base resistance on Okinawa in 2012 when it arrived on the island to replace the Marines’ aging fleet of Sea Knight helicopters. The aircraft has since been the focal point of near daily protests, and expelling it from the island was a major campaign promise of Gov. Takeshi Onaga’s during the 2014 election.
According to the US official, the Osprey crashed after clipping the back of the USS Green Bay while trying to land on the amphibious transport ship. The Okinawa-based aircraft which crashed was in Australia as part of a joint military exercise called Talisman Sabre, which has just ended in Queensland state.
The "distributed laydown" in the Pacific, which dovetails with the Marine Corps' expeditionary nature and ability to rapidly move forces from one place to another, calls for moving more than 4,000 Marines from Okinawa, Japan, to Guam. Whelden said hundreds of millions of dollars already have been invested on Guam, with wharves to support amphibious ready group ships already completed and ramp and hangar work ongoing for Ospreys and the new F-35B Lightning II, which the Corps called the "world's first operational supersonic short takeoff and vertical landing fighter." "We aren't basing F-35s in Guam, but we train on Guam a lot," Whelden said. Ten of the stealth fighters this week were sent to Iwakuni, Japan, with six more expected to arrive this summer. Whelden said the relocation of about 2,700 Marines from Okinawa to Hawaii is about 10 years away.
More than half of the 50,000 American troops in Japan are stationed on Okinawa under the Japan-US security treaty.
Nearly three quarters of US military resources in Japan are located on the small archipelago to the south of most of Japan’s islands, and residents say they have long been inconvenienced by the base, which was constructed following the country’s defeat in World War II.
