THE USS Green Bay pulled into the Port of Darwin on Wednesday with assault and utility helicopters on her deck and a 41m landing boat in her guts.

“Our charge is to make sure those marines are where they need to be, when they need to be there, ready to fight,” Capt McCallum said.

“What this entails is amphibious landings both from air and sea.

“We’ll have landing craft (and) helicopters on board that will be able to transport the Marines and equipment to where they need to be.”

This year, for the first time, amphibious landings that previously took place in Queensland as part of the biennial wargames will now turn to public beaches in Fog Bay, threatening sensitive turtle nesting events.
