Military activity in the Territory is set to soar, with more than one thousand Marines arriving in the Top End for the 13th rotation of Marine Rotational Force - Darwin.

On Friday, Marines got a taste for the Top End’s conditions as they stepped onto the airstrip tarmac.

The new rotation’s Commanding Officer Colonel Brian Mulvihill said his troops were “excited” to get started.

ADF Commanding Officer Headquarters Northern Command, Captain Mitchell Livingstone, said the next eight months would involve high-end training.

“I’m pleased to welcome the 13th iteration of MRF-D to the Top End,” he said.

“These rotations not only help build interoperability between the ADF and the US, but also serve to increase regional cooperation with partner nations in the Indo-Pacific.

“Over the next eight months, the ADF and USMC will conduct a comprehensive range of training activities, including humanitarian assistance, security operations, and live-fire exercises, all of which better prepare our forces to respond effectively to contingencies that may arise.”

U.S. Marines have returned to northern Australia as part of a six-month training tour across the South Pacific that will also include drills in the Philippines and Indonesia.

They’ll be supported by Marine Medium Tiltrotor Squadron 268 out of Hawaii flying MV-22 B Osprey aircraft.

Ospreys began flying again this month after being grounded following the Nov. 29 crash of an Air Force Osprey off the coast of Japan that killed eight airmen. An Osprey crash in Australia in August killed three Marines attached to Marine Medium Tiltrotor Squadron 363 during last year’s rotation to the Northern Territory.

In Australia, the Marines will join numerous training events, including Southern Jackaroo, which typically involves Japanese troops; Bhakti Kanyini AUSINDO, which involved Indonesian forces last year; and the aviation-focused Pitch Black, Diamond Storm and HELICON LUK.

The US Defence Department is seeking businesses for extensive upgrades to RAAF Base Darwin.

The works are part of the US Force Posture initiative to enhance security in the Asia-Pacific region - including construction of a parking apron, a maintenance support facility and an aircraft maintenance hangar at RAAF Base Darwin.

The contract also includes an aircraft rinse facility, aircraft wash rack, helicopter landing pads and supporting facilities as well as construction of Marine aviation logistics squadron and Marine wing support squadron facilities - as well as a Type 11 aircraft maintenance hangar, telecommunications distribution facility, supporting facilities, utility connections, site improvements and earthworks.

Under the Force Posture, Australian businesses and joint ventures have won United States-funded infrastructure contracts to the value of almost US$200m.

This includes the completion of a new fuel facility at RAAF Base Darwin to support enhanced air co-operation between the United States and Australia and construction of a US tank storage facility at East Arm, which is behind schedule but expected to be completed by July.

In addition, tens-of-millions was spent upgrading RAAF Base Tindal in Katherine to support KC-30A multi role tanker transport operations, which Defence said will enhance air mobility, including air-to-air refuelling and air logistics support missions.

Tens-of-millions more have been spent developing the MQ-4C Triton drone, four of which will be deployed at RAAF Base Tindal near Katherine from later this year.

An American Marine whose alleged rape of a woman in Palmerston resulted in his team being locked down in Robertson Barracks has appeared in court for the first time.

A 20-year-old American, who cannot be named for legal reasons, was charged with aggravated assault and sexual intercourse without consent following an alleged incident on Monday September 18.

His matter was adjourned until November 20 for preliminary examination mention, meaning the case could proceed to the Supreme Court. The rest of the Marines are due to leave Darwin in October

An American Marine has been arrested and charged after allegedly raping a woman in Palmerston, near Darwin in the Northern Territory.

A US Defence Force spokesman confirmed a 20-year-old Marine was arrested by NT Police and charged with aggravated assault and sexual intercourse without consent.

A NT Police spokeswoman said the 20-year-old’s arrest on Monday, September 18, was in relation to an alleged incident in Palmerston that same day.

It is understood that all Marines at the Robertson Barracks are unable to leave or allow visitors on base, with the US Defence Force spokesman saying there was a “restricted liberty status” at the base.
