Major construction, funded by the U.S. and Australian governments, is underway in Australia’s Northern Territory for facilities that will be used by the U.S. Air Force, Navy and Marine Corps.

The facilities will support U.S. and Australian forces training to defend chains of small islands that would likely be an arena for any future conflict with China, according to former Australian assistant defense secretary Ross Babbage.

The allies are learning to conduct dispersed operations and deploy anti-ship missiles to island chains in the Western Pacific “to make it extremely difficult and dangerous for Chinese operations in a crisis,” including a conflict over Taiwan, he said by phone Wednesday.

The Australian government will likely announce more initiatives in the northern Australia before the year is over, Babbage said.

Following the AUKUS nuclear-powered submarine deal, a senior US official reportedly said recently that the US would consider providing Australia with nuclear-capable B-21 bombers, the in-development successor to the B-2 stealth bomber that experts said on Wednesday would enable Australia to launch long-range strikes against China, thus posing serious threats to China.

US Air Force Secretary Frank Kendall made the remark at a media briefing after meeting with newly minted Royal Australian Air Force chief Air Marshal Robert Chipman on August 22 in Canberra, The Strategist, a website affiliated with the Australian Strategic Policy Institute, reported on Tuesday.

Kendall again hyped the "China threat" theory, claiming the US and its allies were "concerned about Chinese behavior" in the South China Sea as well as China's military modernization program.

Song Zhongping, a Chinese military expert and TV commentator, said if Australia obtains the B-21, the country would essentially become an overseas bomber base of the US,

US Marines of the Marine Rotational Force-Darwin (MRF-D) and members of the Australian Defence Force from Australian Army’s 1st and 13th Brigade, and Royal Australian Air Force’s 36th, 37th and 75th Squadrons have commenced Exercise Koolendong this week across the Top End.

The three week warfighting exercise is being held at Defence training areas in the Northern Territory and for the first time, in Western Australia to simulate a response to a regional security crisis.

“We are deploying significant forces by land, air and sea to training areas in both WA and the NT including Mount Bundy Training Area, RAAF Base Curtin & Yampi Sound Training Area,” Colonel Steele said.

The Marine Rotational Force-Darwin (MRF-D) Aviation Combat Element (ACE) has arrived in Darwin.

The aircraft are critical to accomplishing Marine Air Ground Task Force (MAGTF) missions and tasks in 2022.

As one of the major subordinate elements of the MAGTF, the ACE offers much more than just aircraft in the skies.

Led by Marine Medium Tiltrotor Squadron 268 (VMM-268), and joined by detachments from Marine Air Control Group 38 (MACG), Marine Wing Support Squadron 174 (MWSS), and Marine Aviation Logistics Squadron 24 (MALS), the MRF-D 2022 ACE provides mobility, response, and awareness to the MAGTF.

Compared with traditional rotary-wing platforms, the MV-22 extends the operational reach of the MAGTF which will be showcased during the exercises of this year’s rotation.

F-35B Lightning IIs from Marine Corps Air Station Iwakuni, Japan, will participate in Australia’s biennial Exercise Pitch Black, Marine Aircraft Group 12 spokesman Gunnery Sgt. Vitaliy Rusavskiy said in an email Thursday.

Pitch Black involves the Royal Australian Air Force working with regional, coalition and allied nations. It will take place from Aug. 19 to Sept. 8

Ten MV-22 Osprey tiltrotor aircraft deployed with the rotational force from Marine Medium Tiltrotor Squadron 268, out of Kaneohe Bay, Hawaii, will participate in Pitch Black, DiPietro said.

Marines from Air Control Group 38, part of the rotational force, will also take part in Pitch Black
