Australia plans to buy three used American submarines. What do we know about them?
We know their class and the broad transfer timetable. We do not know which submarines Australia will receive, how old they will be, what condition they will be in or how much service life will remain.

What people heard
Australia has already chosen the exact three used American submarines it will buy.
Partly established
Do we know which boats Australia will receive?
Short answer. The class, number and broad timetable are public. The individual boats, their ages, condition, price and remaining service lives are not.

Which view do you want to understand first?
Each view notices something useful. None is allowed to stand in for the complete evidence.
Defence capability
The transfer is intended to bridge the period before locally built submarines arrive.
What this view explainsWhy timing and operational availability matter to the pathway.
What it may missStrategic need alone does not establish the value or condition of the boats.

The answer
The plan changed. All three are now expected to be used.
01
The original plan
Australia intended to buy at least three Virginia class submarines. The first two were expected to be already in service. The third was expected to be new.
02
The current plan
In May 2026, the three countries announced a simpler approach. Australia would receive three submarines already in service instead.
03
The missing answer
The government says it knows how old the submarines will be. It has not disclosed their ages, hulls, condition or remaining service life.
Why age matters
The word “used” does not reveal how much useful life Australia will receive.
Defence Minister Richard Marles told ABC television that the typical life of a Virginia class submarine is about 33 years. He was asked how old the three submarines would be when Australia received them. He said he knew, but would not disclose the detail.
A submarine that is five years old at transfer is a different purchase from one that is 20 years old. Age can affect how long it can serve, when major work is needed and how much replacement capability Australia must plan for.
Used does not automatically mean unsuitable. The United States Navy maintains submarines throughout their service lives. But without the age, maintenance history, transfer condition and expected retirement date, the public cannot calculate the value Australia will receive.
The timetable
Rotations come first. Australian ownership comes later.
From 2027RotationsUnited States and United Kingdom submarines begin rotating through Western Australia.

then
Early 2040sFirst local boatAustralia plans to deliver its first locally built SSN AUKUS submarine.
These are planned windows, not guaranteed delivery dates. The first Collins class submarine is expected to retire around 2040, so delays or changes in either program matter.
What the headline leaves out
Four questions that still change the value of the deal.
01
Which submarines?
The names and hulls have not been announced. Without them, their build dates and service histories cannot be checked.
02
How much life is left?
No public answer shows the expected remaining service life of each submarine when it reaches Australia.
03
What will each one cost?
The program has large published funding totals. A final public price and transfer condition for each submarine are not available.
04
Who controls them?
The official position is that they will fly the Australian flag, be commanded by the Royal Australian Navy and act under Australian Government direction.
What remains unknown
The public knows the class and broad timetable. It does not yet know the boats.
The age and identity of each submarine
The maintenance and operating history of each submarine
The expected remaining service life at transfer
The final price and condition of each transfer
The exact delivery dates
Where Australia will permanently store its own nuclear waste
These are not minor details. They determine what Australia receives, how long it can use it and what must be paid for next.
The simple test
Ask for the age before judging the purchase.
Three submarines can sound like one clear promise. The useful questions are which three, how old, in what condition and with how many years left. Until those answers are public, the size of the purchase is clearer than its value.
