Ten MV-22B Ospreys ‘tiltrotors’ from the US Marine Corps based in Hawaii have recently arrived at the Royal Australian Air Force Base in Darwin to join the 2,500-strong rotational force training to respond to regional crises, contingency, and humanitarian assistance during disasters.
The Ospreys, its flight crew, and support personnel make up the air combat component of Marine Rotational Force Darwin which started its yearly seven-month alternation last month.
Some know the accident-prone Osprey as the Widowmaker.
Last year, five marines died during a training mission in Glamis.

Osprey have been particularly controversial in Okinawa, ever since one crash-landed in a university in 2004. A crowd reportedly as large as 100,000 protested in Japan earlier a few years ago against plans by the US military to deploy further MV-22 Ospreys to a US base on Okinawa.

Other recent incidents include fatal crashes of the aircraft in Morocco and Florida, and an emergency landing in 2012 that narrowly missed a church in North Carolina.
