"The EAC initiative has been operating successfully for several years as one of the United States Force Posture Initiatives," she added.
"The RAAF welcomes the visiting aircraft and personnel and looks forward to working with them during this activity."
Lieutenant Colonel Andrew Kousgaard, US Air Force 393rd Expeditionary Bomb Squadron commander, said that the visit was more than just about training and it was about sending a message.
"This deployment of the B-2 to Australia demonstrates and enhances the readiness and lethality of our long-range penetrating strike force," Kousgaard said.
"We look forward for training and enhancing our interoperability with our RAAF teammates, as well as partners and allies across the Indo-Pacific as we meet (Pacific Air Forces Bomber Task Force) objectives."
The 393rd Bomb Squadron is still the only unit that have deployed nuclear weapons in combat, as the bombings of the Japanese cities of Hiroshima and Nagasaki at the end of World War II both conducted by them.
B-2's deployments to Australia was telegraphed last year in a Pentagon review also, where it was noted that new rotations were needed to "deter potential Chinese military aggression and threats from North Korea."
The B-2 jet can deploy both conventional and nuclear weapons.
