What the impact of Australian aging SSK Collins submarines (6) to the equation?
According to a fairly recent
, which is owned by the Australian government, from November 2024, of Australia's six Collins class submarines,
only one boat is fully operational at the moment
:
The Australian Navy has been left with just one fully operational submarine as the rest of its aging Collins-class fleet undergoes urgent repairs or waits to complete scheduled upgrades.
Three boats were determined to be non-operational and in need of major overhauls thanks to severe corrosion, but things apparently aren't proceeding smoothly due to labor issues:
Since then, workers began strike action at the government-owned ASC maintenance and sustainment facility in Adelaide as they continued their long-running dispute seeking pay parity with ASC workers in Western Australia.
From the sounds of the ABC report, the three remaining Collins boats are probably in rough shape too, and only one is reasonably deployable, likely due to deferred maintenance and/or simply inadequate planned, yet completed maintenance taking a toll on overall mission readiness across the board.
If only one boat is reasonably operational, and considering the overall age of the design and systems, the Collins isn't going to add much to the RAN, if at all.
Perhaps the Collins' greatest impact on the Australian military is its knack for affecting budgets elsewhere, considering what
:
The LOTE will
keep the Collins Class submarine operationally capable and available into the 2040s, supporting the transition to Australia's nuclear-powered submarines.
- Budget: $4.3 - $6.4 billion
- Timeframe: First LOTE scheduled for mid-2026
- Industry: more than 1500 jobs
- Location: Osborne South Australia (LOTE) and Henderson Western Australia (sustainment)
Moreover, not only does the Collins class lack any sort of AIP, it has been
plagued with problems -- if not
cursed as a program -- over the decades, and may or may not be reasonably serviceable into the 2040s, or even the 2030s, at which point it may already be fairly
obsolescent by regional standards.
