Osprey's.

 A set of MV-22B Osprey tiltrotor aircraft fly in formation above the Pacific Ocean off the coast of Sydney, Australia, June 29, 2017. The MV-22Bs belong to Marine Medium Tiltrotor Squadron 265 (Reinforced). VMM-265 (Rein.) is part of the Aviation Combat Element of the 31st Marine Expeditionary Unit. The 31st MEU and the Bonhomme Richard Expeditionary Strike Group arrived in Sydney after transiting south across the vast Pacific Ocean, from Okinawa, Japan, to southeastern Australia in just over three weeks. Sydney is a favorite port stop for both Marines and Sailors crossing the Pacific. The 31st MEU partners with the Navy’s Amphibious Squadron 11 to form the amphibious component of the Bonhomme Richard Expeditionary Strike Group. The 31st MEU and PHIBRON 11 combine to provide a cohesive blue-green team capable of accomplishing a variety of missions across the Indo-Asia-Pacific region.
