Report of the test launch comes as tensions soar between Russia and the West over the fighting in Ukraine.

The Prime Minister and the US President have presented a united front amid current global uncertainty.

The recovery team also hauled up the titanium endcap of the vessel, which imploded deep deep beneath the Atlantic Ocean's surface.

There would be massive global impacts from any such incident, according to a US report.

Taiwan's first homemade submarine has been greeted with a stark warning from its superpower neighbour.

The legal filing cited a law that protects and preserves the shipwreck as a gravesite.

Defence Minister Richard Marles has brushed off concerns the US Congress may block Australia's bid to buy American submarines.

The company's website has been updated with a message for visitors, following the fatality.

The return is a key piece of the investigation into why the submersible imploded, killing all five people on board.

The find comes a day after huge pieces of the doomed submersible were hauled off the seafloor off the coast of Canada.

The mother of teenager Suleman Dawood, who died in the Titan submersible, said her son loved solving his Rubik's cube and even took it on board with him.

With rescuers and the public fixated first on saving and then on mourning those aboard the Titan submersible, it has made for uneasy conversation.

One grabbed unrelenting, moment-to-moment attention. One was watched and discussed as another sad, but routine, news story.

Authorities have begun the process of probing the cause of the underwater implosion and grappled with questions of who was responsible for determining how the tragedy unfolded.

Questions remain about what exactly happened to the ill-fated vessel, and whether the bodies can be recovered

Stockton Rush wore a hard-hat and stood next to one of his submersible crafts last year full of enthusiasm as he told a bunch of students about the thrills and perils of being a deep-sea explorer.

There's no other comparable ocean search, especially with so many countries and even commercial enterprises being involved, naval historian, Norman Polmar, said.

As officials work to determine the timeline and circumstances of the accident, remotely operated vehicles will be used to map out the Titan's debris field more than 3.2kms deep in the ocean.

Eight hours. And within them, many unanswered questions.

US film director James Cameron, who helmed the hit 1997 film Titanic and has himself made 33 dives to the wreckage, has spoken after it was announced that a missing Titanic-bound submersible suffered a "catastrophic implosion," killing five people on board.

He described the OceanGate CEO as a tinkerer who tried to make do with what was available but said "it was a bit dubious".

The US navy agreed to help him look for the Titanic - on the condition that he first help them locate two missing nuclear submarines.

Explorer Chris Brown said he had paid a deposit to go down in an OceanGate trip but ultimately backed out.

Only a handful of people have seen the Titanic's wreckage in person, because precious few have what it takes to visit: the financial resources, access to experts – and a willingness to accept the significant safety risk.

More search vessels, including a 'state-of-the-art' remote-operated vehicle from France, are heading to the North Atlantic.

A plane flying overhead has picked up "banging sounds", but the clock is ticking fast.

If five people onboard the missing submersible are still alive they may have little more than 24 hours of oxygen to breathe inside the small six-metre Titan.

Civilian submersible may have suffered a catastrophic leak, an electrical fire, a power blackout or even been swept up in a tremendously powerful underwater current.

A British businessman is one of the crew members on board a submersible that went missing on the way to see the Titanic.

Piloted by a video game controller, a TV reporter says the vessel "got lost for a few hours" when he was on it last year.

Realising the full potential of the landmark defence deal depends on a 'seamless' exchange of technology, Richard Marles said today.

The federal government will dramatically reduce their planned purchase of tanks and howitzers to free up money for other defence priorities, Nine Newspapers reports.

But Defence Minister Richard Marles has hit back, saying the government's position on nuclear submarines remains consistent.
