Mr Healey, fresh from the Nato summit in Washington DC, visited Sheffield Forgemasters, which is owned by the Ministry of Defence, alongside his Australian counterpart.
He reaffirmed the UK’s commitment to Aukus and emphasised its role in job creation.
Mr Healey said: “Working with allies and partners is fundamental to our security and so it is a pleasure to host my Australian counterpart within my first fortnight as defence secretary.
“The UK and Australia are the closest of friends and our work through Aukus is testament to this.”
The MP for Rawmarsh and Conisbrough, in South Yorkshire, added: “Sheffield Forgemasters is a shining light of UK industry that helps boost global security and employs skilled staff from the local community.
“This is just one example of how our hugely important partnership with our Australian and American partners can help drive jobs and growth across Britain.”
The visit comes after Prime Minister Sir Keir Starmer spoke to his Australian counterpart, Anthony Albanese, with the leaders outlining their commitment to partnership.
Mr Marles has also visited HMNB Clyde, in Scotland, to see first-hand how the UK operates its nuclear submarine base.
