L’Australie fait du maintien en service de ses six sous-marins Collins un « sujet de préoccupation »

Australia makes keeping its six Collins submarines in service a ‘matter of concern
by Laurent Lagneau - 14 December 2024
At the beginning of November, the Australian Broadcasting Corporation [ABC] revealed that only one of the six Collins submarines owned by the Royal Australian Navy [RAN] was seaworthy. It had previously been reported that corrosion had been discovered in the torpedo tubes of two other units, HMAS Farncombe and HMAS Sheean.
For the RAN, it is imperative that these six ‘Collins’ remain in service until the delivery of the nuclear attack submarines [NAS] it is due to receive under the AUKUS pact, signed by Australia with the United States and the United Kingdom in September 2021.
As a reminder, this led Canberra to cancel the acquisition of twelve Shortfin Barracuda [or ‘Attack’] submarines from France's Naval Group. Some people seem to regret this, as shown by an article recently published by the Australian Strategic Policy Institute [ASPI], a think tank funded by... the Australian Department of Defence.
The ASPI felt that ‘we should probably go back to the work done for the Attack class’, given the difficulties encountered in the AUKUS pact. In fact, the delivery by the United States of three Virginia-type SNAs to the Australian Navy seems risky insofar as the US Navy is already struggling to obtain its own, as the American naval industry has not yet managed to increase its production rate.
The five other SNAs promised to the RAN are to be built in cooperation with the UK. However, as the ASPI article points out, the PWR3 reactor that is to equip them ‘has not yet been tested’ and the UK's priority is the commissioning of the future Dreadnought nuclear-powered ballistic missile submarines (SSBNs). What's more, British industry seems to be struggling to maintain the Royal Navy's Astute submarines in operational condition. Last August, none of them were on mission...
Be that as it may, extending the six Collins-type submarines beyond their operational life, i.e. until the 2030s, remains the Australian Navy's priority. To this end, it has launched the LOTE [Life Of Type Extension] programme, costing around €3 billion. However, it has had to scale back its ambitions, notably by abandoning its plans to equip the navy with the capacity to launch Tomahawk cruise missiles, as this operation was not deemed economically viable.
The LOTE programme will not be enough to extend these submarines. In July, the RAN awarded a €1.3 billion contract to the ASC Pty Ltd shipyard to maintain them in operational condition for four years.
However, these efforts may not be enough to guarantee the Collins' availability. And a temporary breakdown in capacity is looming on the horizon. At least, that's what the Australian Department of Defence fears, having just announced its decision to classify the MCO of these submarines as a programme of ‘concern’. In plain English, this means that the programme will be placed under ‘enhanced scrutiny’.
‘As the submarines are expected to operate beyond their design life, it is essential to meet increased sustainment requirements to ensure that the Collins class remains an effective and formidable capability until it is withdrawn from service’, he explained. He will also present an action plan to address the highest risk vulnerabilities.
‘The Government is committed to investing in priority capability improvements... to ensure that the Collins Class submarine fleet remains a powerful and credible capability to conduct operations to protect Australia's maritime approaches and sea lines of communication,’ he added.
In the meantime, this decision suggests that extending the operational life of the Collins submarines will be more complicated than anticipated, which, depending on the evolution of their condition, could force the RAN to impose operational restrictions on them.
