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

The Enhanced Air Cooperation initiative focused this year on fifth-generation fighter integration, aero-medical evacuation and aircraft maintenance.

Thousands of U.S. Marines on an Australian Army base this summer might be the most visible example of America’s growing military presence Down Under. But the nations’ air forces are growing equally close under a lesser-known program known as Enhanced Air Cooperation, or EAC.

The initiative, which kicked off in 2017, focused this year on fifth-generation fighter integration, aero-medical evacuation and aircraft maintenance. It involved U.S. F-22 Raptor, F-35B Lightning II, F-16 Fighting Falcon and F-15 Eagle fighters, B-52 strategic bombers and C-130J Super Hercules transports.

The Air Force’s activities in the Northern Territory, along with those of the Marines, are being supported with $2 billion worth of new military infrastructure funded by the U.S. and Australia, according to the Australian Defence Force.

At RAAF Darwin, for example, $88.65 million worth of projects have been awarded to build fuel tanks, expand the airfield and erect maintenance facilities.

These and other projects at RAAF Darwin are scheduled to be accomplished by 2023

“The major motivator for U.S. force restructure and redeployment on the western Pacific rim is China. It’s as simple as that”

The United States military is preparing to spend more than a quarter of a billion dollars on naval construction in the Northern Territory, in a move that could raise tensions with China.

the Defence Department says it is still too early to comment on what the US military may have planned in the Northern Territory.

"The referenced document is the Senate version of the National Defense Authorization Act, which authorises (but does not appropriate) Defence initiatives," the Department said in a statement.

"It is still progressing through the US Congress and must be reconciled with the House version before it is finalised. It is not yet approved.

"We expect the US Department of Defense will provide details of the funding in accordance with its processes and timelines following consideration and approval within the United States Government."

The draft US legislation also outlines several other proposed spending projects in the Northern Territory including $US50 million for a "new airport parking apron for the Navy", and $US70.6 million for the Air Force at Tindall.

Ecuador’s decision to allow US planes to use a San Cristobal airfield prompts environmental concerns.

Opposition congressman Carlos Viteri said the agreement with the US was "unacceptable" and should be prohibited if "it intends to cede an inch of Ecuadorian territory".

Under Article 5 of Ecuador's constitution, the country is "a territory of peace" and the "establishment of foreign military bases or foreign facilities for military purposes shall not be allowed".

Ecuador's former president Rafael Correa also reacted angrily, tweeting (in Spanish) that the island was "not an aircraft carrier" for the Americans.

The Galapagos Islands, 563 miles (906km) west of continental Ecuador, are a Unesco World Heritage site renowned worldwide for their unique array of plants and wildlife.

TWO military aircraft experienced mid-flight malfunctions over Top End skies within 24 hours of each other.

A Royal Australian Air Force spokeswoman said a C130 aircraft a USAF F-16 fighter jet were involved in separate incidents on Monday and Tuesday.

She said a C130 aircraft was returning to Darwin at 5.35pm on Monday when an engine “malfunctioned”, but the aircraft was able to land safely without incident.

The next day the USAF F-16 aircraft experienced an in-flight emergency and was forced to return to the base early ending its flight.

“The aircraft dumped fuel in accordance with normal procedures. The aircraft landed safely using the cable at approximately 9.10pm

Exercise Diamond Storm began in late April and runs until May 29 with aircraft operating out of RAAF Bases Tindal and Darwin. According to the RAAF, the exercise is the final phase of the Air Warfare Instructor Course, a three phase intensive six-month course that integrates war fighting functions across a range of specialisations.
