A US Navy ship has docked in Darwin, with hundreds of sailors expected to explore the Top End during the routine stopover aimed at enhancing relations between the two allies.

Complete with a barbershop, retro diner, post office, corner store, dentist, and emergency operating theatre, USS Emory S. Land serves as a floating city wherever she is deployed.

“Our mission is to repair, rearm, and resupply deployed submarines and surface ships, both of US and our partner navies,” Captain Brent Spillner said.

“Two thirds of our crew works in the repair department, so maintenance specialists such as welders, electricians, and we’ve also got a very capable weapons department – we’ve got the ability to reload torpedoes, mines, missiles.

“We are self contained, we could go into a very austere, remote port and still provide the same services a ship would have if it were in a major port.”

“Darwin basically marks the midway point for our current secondment. This represents a massive milestone for us in terms of an opportunity to demonstrate all the skills we have, and really be able to contribute to the operation of the ship.”

An American warship is pulling into Darwin with a view to enhance US– Australian relations, with crewmen expected to roam the city in the coming days.

It was also confirmed members of the Royal Australian Navy were on-board the Emory S. Land to develop their knowledge, skills and experience in how their American counterparts conducted nuclear-powered submarine maintenance.

The arrangement to offer submarine-related training to ADF personnel follows Australia’s commitment to bringing into service multiple nuclear-powered Virginia class submarines, expected to patrol Australian waters as early as the 2030s.

The arrival of Emory S. Land coincides with the ramped up military activity currently underway across the Top End, with ADF and Marine Rotation Force – Darwin, integrating at Mount Bundey Training Area.

The lawsuit, filed by the families of Sax, Carlson, Strickland and Rasmuson, accuses Boeing, Bell Textron, Rolls Royce Corps and Rolls Royce North America of negligence, negligent and fraudulent misrepresentation, and the failure to warn.

Tim Loranger, the lawyer representing the families in the lawsuit, told CNN on Thursday that ultimately the lawsuit alleges that the aircraft the Marines were on was known to have a defect but “insufficient steps have been taken to correct it.”

The lawsuit comes months after another deadly V-22 Osprey crash off the coast of Japan, which resulted in the deaths of eight US Special Operations airmen. The US military grounded its entire fleet of V-22 Ospreys in December as a result. That grounding guidance was lifted in March this year; officials said at the time an investigation identified a “materiel failure” responsible for the crash.

Col. Brian Taylor, the program manager of the Naval Air Systems Command V-22 joint program office, told reporters in March that the crash resulted from an “unprecedented” component failure, though he declined to say what component specifically failed or how.

A US Marine appeared in court after being charged with rape, charges he will seek to contest.

The man appeared in the Darwin Local Court on Wednesday charged with sexual intercourse without consent.

He was joined in court by members of his marine corps.

The case returns for a preliminary examination mention on July 3, where the defendant is excused.

The US military could be waiting until next year for the handover of 11 fuel storage tanks currently under construction at Darwin’s East Arm.

Originally scheduled for completion last September, the opening was put back until this July but with just weeks to go, construction flaws and permitting issues continue to dog the $270m development.

The liners beneath the tanks are leaking, environmental permits remain in limbo and building certifications are unresolved.

A spokesperson for the Department of Infrastructure, Planning and Logistics, which has carriage over certification, said under the Act, a building permit was required before work starts, and work must be certified or approved at the end of construction before occupancy.
