According to the Chief of US Naval Operations Adm. Jonathan Greenert, Air-Sea Battle (ASB) is a centerpiece in the Navy’s “pivot” to Asia. Designed to counter the PLA’s growing “anti-access/ area-denial” challenge to forward operating US forces, Asian allies are expected to play a key role in supporting and implementing the concept. This includes Australia, one of America’s closest allies in the region. However, the US would be ill advised to take Australia’s support for granted. Indeed, Washington needs to do much more to explain Air-Sea Battle’s rationale to Canberra.
