The U.S. is planning to deploy up to six of its nuclear-capable B-52 bombers to Australia, the latest in a series of moves by the partners amid soaring tensions with China.

The United States is funding a project to build an aircraft parking apron capable of accommodating up to six B-52s and other aircraft at the Royal Australian Air Force’s Tindal base in northern Australia, according to the Australian Defence Ministry.

“The project provides functionality for Australian Defence Force use and can also host other aircraft types, enhancing our capacity to train with and host international partners,” a ministry spokesperson told The Japan Times late Monday.
