As the US deepens its security focus on the Indo-Pacific region, it has focused on keeping its edge underwater over rivals such as China.

This includes its plans to share nuclear-powered submarine technology with Australia as part of a new trilateral defence partnership that also includes Britain.
Analysts said the US Navy was still well ahead of China in undersea warfare, but that the Chinese People’s Liberation Army Navy (PLAN) has spent billions in recent years to narrow the gap.
According to a report this month by the Washington-based Hudson Institute, the submarine threat for the US and its allies has increased substantially, including from the modernisation of the Chinese navy’s fleet of around 65 to 70 submarines.
The report said China sought to conduct offensive operations as part of an active defence strategy, to expand the country’s influence and territorial control, potentially hindering US forces in the region.
“Submarines are an increasingly important element of adversaries’ weapons portfolios, delivering key capabilities needed for their strategies,” the report said.
