More than $1b additional investment in making us reliant on the USA: major runway extensions, fuel stockpiles and engineering will be designed to support “Code E” large aircraft, such as US Air Force B-52 strategic bombers and RAAF KC-30 air-to-air refuellers.

Mr Morrison told The Australian the $1.1bn spending comes on top of almost $500m that had ­already been planned for Tindal.

Under the US Force Posture Initiative signed in 2011 by the ­Gillard government and Obama administration, the US and Austral­ia committed to joint funding for military infrastructure project­s of about $2bn.

This included an increase in the annual rotation of US marines through Darwin to about 2000. The Tindal program will be funded under Australia’s contrib­ution, after the US announced it would spend $305m in upgrading infrastructure in Darwin

“These are (the) sorts of things you can do when you manage money well and invest in priorities of keeping Australia safe and building the capability of our defenc­e forces.” #FFS

It has been painfully obvious for years that our major ally, the US, major regional partner, Japan, and our major market, China, all see more strategic value in northern Australia than successive federal governments and much of our Defence establishment.

At a time when the US has been trying to reduce the burden of overseas military commitments, the “rotational deployments” of US Marine Corps troops to the Top End — now in their ninth year — are based on an American judgment that northern Australia is increasingly important to Asia’s security.

In the face of a more aggressive China with stronger military forces, the US is dispersing its own forces in Asia. While it’s right to say that 2500 marines is hardly a threat to Beijing, it’s an important demonstration of America’s commitment to Australia and Southeast Asian security.

The U.S. Marines with 3rd Battalion, 12th Marine Regiment, a part of Marine Rotational Force-Darwin (MRF-D), fired Guided Multiple Launch Rocket System munitions, known as GMLRS, during Southern Reach, at Bradshaw Field Training Area, Northern Territory, Australia on August 15, 2019.

The HIMARS Marines fired two GMLRS in Australia for the first time ever, according to Cpl. Kallahan Morris. The HIMARS is a weapons system made up of the M142, five-ton chassis vehicle and can carry either a launcher pod of six rockets or one MGM-140 Army Tactical Missile System (ATACMS).

The live-fire training conducted was over an area of 3,282 square miles.

HIMARS is participating in MRF-D for the first time. These Marines and equipment provide MRF-D an extended range precision strike capability that can further shape the battlespace.

the HIMARS Marines with MRF-D conducted multiple fire missions, shot two GMLRS rounds, and enjoyed training in the heat of Australia’s Northern Territory dry-season.

America has allocated more than quarter of a billion dollars for Osprey aircraft infrastructure in Northern Australia.

The US Defence Department is looking to spend $305.9 million on facilities for their Osprey fleet, Chief Minister Michael Gunner told NT Parliament on Wednesday, while knocking back a suggestion that the money would be spent on a new naval base in Darwin.

"The budget appropriation that is being sought in America is for ramps for the Ospreys in the Northern Territory, not for a naval installation," Mr Gunner said.

"The Ospreys are aircraft vehicles. That is where the money is intended to go."

In July, the ABC revealed that a draft US Congressional bill had $US211.5 million allocated for new "Navy Military Construction" in Darwin, with few other details available.

Mr Gunner said that following these reports, he had reached out to US Secretary of Navy Richard Spencer, to clarify the nature of the spending.

The ABC understands plans for a new commercial port facility were still being discussed.

The US military is considering investing more than $211 million into construction in Darwin, Australia, according to the Senate's version of the annual defense legislation.

What that money will build is unknown. The Marine and Navy officials Marine Corps Times reached out to have yet to provide a statement.

Australian outlet ABC News reported that secret planning is underway to develop a new commercial port just outside of Darwin that could eventually be developed to house Australia's landing helicopter dock ships or the US amphibious assault ships that ferry Marines around the globe.

While Australia is one of America's most important military allies in the Pacific, the military construction could cause diplomatic headaches for Australia and sour its relationship with China, which over the years has become more economically intertwined.

"...even our best allies, the Australians, they're with us from a military perspective, but economically they're tied to China," Maj. Gen. Daniel Yoo, the commander of the Marine Raiders, told Marine Corps Times in an interview during a May special operations conference in Tampa, Florida.

"And so they have a problem internal to their own country as far as there's some that feel they should be closer to China, because their economic health is dependent upon it."

Congress may review the Corps' plan to redistribute its forces across the Pacific.
